Overall remediation

As at the end of July 2026, there are 4,697 residential buildings 11 metres and over in height identified with unsafe cladding whose remediation progression is being reported on in this release, an increase of 228 since the end of June 2026. This is an estimated 64-81% of all buildings 11 metres and over in height expected to be remediated as part of MHCLG’s remediation programmes. Information on the increase of 228 buildings is available in the Overall Remediation section of the data release.

Since the department first began reporting on all five remediation programmes in October 2023, the overall number of 11m+ buildings with unsafe cladding whose remediation progress is being monitored by MHCLG is 900 more.

Overall, 2,551 buildings (54% of monitored buildings) have either started or completed remediation works. Of these, 1,833 buildings (39% of monitored buildings) have completed remediation works.

Figure 1: 4,697 11m+ buildings have been identified with unsafe cladding, and there are an estimated 1,100-2,600 11m+ buildings expected to be remediated as part of MHCLG’s remediation programmes yet to be confirmed as eligible for a remediation programme.

Figure 2: Of the 4,697 buildings identified with unsafe cladding, 2,551 (54% of monitored buildings) have started or completed remediation works, of which 1,833 (39% of monitored buildings) have completed remediation works.

Note: The total number of buildings identified with unsafe cladding, reported in the Overall Remediation section of the data release, does not sum to the total number of buildings in each remediation programme, reported in each respective section of the data release. This is due to some buildings appearing in more than one remediation programme.

The total number of 11m+ buildings identified with unsafe cladding decreased between November 2025 and December 2025 due to a change in the data collection and categorisation of social sector buildings used in our monitoring and reporting. The overall remediation progress figures from December 2025 are therefore not directly comparable to prior months. Fluctuations in the social self-funded data is expected over the coming months, which will affect the overall remediation progress figures. Further information is available in the Technical Note.

ACM remediation – monthly update (as at 30 July 2026) since previous publication.

As at 30 July 2026, of the 516 high-rise (18 metres and over in height) residential and publicly owned buildings with ACM cladding systems, unlikely to meet Building Regulations, 502 (97%) have either started or completed remediation works, an increase of two since the end of June.

Of these, 478 buildings (93%) have completed ACM remediation, including those awaiting building control sign-off, an increase of one since the end of June.

There are 14 buildings yet to start ACM remediation (3% of all buildings), a decrease of two since the end of June. Two buildings are vacant so do not pose a risk to resident safety, 10 occupied buildings have forecast start dates, one further building has had local authority enforcement action taken against it and the remaining building came into scope in 2026.

Building Safety Fund (BSF) – monthly update (as at 30 July 2026) since previous publication.

As at 30 July 2026, of the 639 high-rise (18 metres and over in height) residential buildings proceeding with an application for funding through the Building Safety Fund, 487 (76%) have completed remediation works, including those awaiting building control sign-off, and 75 buildings (12%) in the BSF have started remediation works on non-ACM cladding.

Overall, 562 high-rise buildings (88%) in the BSF have either started or completed remediation works on non-ACM cladding, no change since the end of June. Of these, 487 buildings (76% of buildings) have completed remediation works, an increase of five since the end of June.

Cladding Safety Scheme (CSS) – monthly update (as at end July 2026) since previous publication.

As at 31 July 2026, 1,438 buildings 11 metres and over in height have been assessed as eligible for the Cladding Safety Scheme (including 280 buildings that have transferred from the BSF), an increase of 43 since the end of June. Of these, 396 buildings (28%) have either started or completed remediation works, an increase of 15 since the end of June. Of these, 127 buildings (9%) have completed remediation works, including those awaiting building control sign-off, an increase of eight since the end of June.

The CSS continues to investigate and pull in potentially eligible buildings. There are a further 2,253 buildings 11 metres and over in height in the pre-eligible stages of the Cladding Safety Scheme, which launched fully in July 2023. Of these, 1,352 buildings are progressing through eligibility checks, and 901 buildings are in the pre-application stage.

Developer remediation – data received from developers as at 30 April 2026. Data received from other programmes relating to developer-led remediation is as at 31 July 2026.

As at 31 July 2026, 2,621 buildings 11 metres and over in height have been identified as having life-critical fire safety defects (including cladding and non-cladding defects) which developers have committed to remediate or pay to remediate (where the cladding remediation works are being carried out in a government funded remediation programme), an increase of seven since reported in the June data release.

Of these, developers reported that 1,264 (48%) have either started or completed remediation works, no change since reported in the June data release. Of these, 596 (23% of buildings) are reported to have completed remediation works, no change since reported in the June data release.

When excluding buildings reported with only non-cladding defects, there are 1,833 buildings which developers have reported as having unsafe cladding, an increase of eight since reported in the June data release. Of which 862 (47%) are reported to have started or completed remediation, no change since reported in the June data release, including 566 (31% of buildings) which are reported to have completed remediation, no change since reported in the June data release.

Social self-funded remediation – monthly update (as at end July 2026) since previous publication.

As at 31 July 2026, there are 742 social buildings identified with unsafe cladding where remediation is self-funded by registered providers of social housing – an increase of 186 since the end of June.

Of these, 574 (77%) are reported to have started or completed remediation works - an increase of 156 since the end of June.

Registered providers of social housing are working with Homes England to finish compiling their records of buildings requiring remediation on the digital platform, the National Remediation Database (NRD). While work is underway to migrate data to the NRD, fluctuations in the remediation progress figures for social buildings where registered providers are self-funding remediation is expected. Further information is available in the Technical Note.

Enforcement – monthly update (as at 24 July 2026) since previous publication

As at 24 July 2026, local authority enforcement action has been, or is being, taken under the Housing Act 2004 against 921 buildings over 11m with suspected unsafe cladding, an increase of 15 since the end of June data release.

Introduction

This Data Release provides data on:

• The estimated number of residential buildings 11 metres and over in height in England that have or had unsafe cladding requiring remediation and the estimated cost to remediate them

• Remediation progress across MHCLG’s Building Safety Remediation portfolio, covering buildings in the ACM programme, Building Safety Fund, Cladding Safety Scheme, developer remediation contract and reported by registered providers of social housing

• Progress with remediation of high-rise (18 metres and over in height) residential buildings (including student accommodation and hotels) and publicly owned buildings with ACM cladding systems unlikely to meet Building Regulations in the ACM programme

• Progress with the applications for and remediation of medium-rise (11-18 metres in height) and high-rise residential buildings in England, and Northern Ireland, with non-ACM cladding systems in the Cladding Safety Scheme

• Progress of remediation of residential buildings 11 metres and over in height with life-critical fire safety risks under the developer remediation contract

• Progress of remediation of residential buildings 11 metres and over in height with unsafe cladding reported by registered providers of social housing as being self-funded

• Enforcement action taken by local authorities against high-rise residential buildings with unsafe cladding under the Housing Act 2004

• In additional management information tables only, the progress of the Waking Watch Relief Fund and the Waking Watch Replacement Fund. From June 2026 this includes data on the Interim Measures Alarm Fund

The data in Figures 3 and 4 and the overall remediation progress section of the data release, shows the combined remediation progress across MHCLG’s Building Safety Remediation portfolio, covering buildings and accounting for crossover in the ACM programme, Building Safety Fund, Cladding Safety Scheme, developer remediation contract and reported by registered providers of social housing as being self-funded.

The figures in this publication are correct as at the specified dates. Remediation progress on the ACM programme, BSF, CSS and social self-funded buildings will be updated monthly, and remediation progress on the developer remediation contract will be updated quarterly.

From June 2025 the Building Safety Remediation data release includes estimates on the number of residential buildings 11 metres and over in height in England with unsafe cladding requiring remediation. These estimates have been updated in the April 2026 Building Safety Remediation data release, and are not expected to change frequently.

From November 2025 the Building Safety Remediation data release includes estimates on the cost of external wall system remediation of residential buildings 11 metres and over in height in England. These estimates have not been updated since the November 2025 Building Safety Remediation data release. These estimates will be updated in the future, but are not expected to change frequently.

Building safety overview

This data release publishes data across all government remediation activities to give an overview of the status of progress to remediate unsafe cladding on residential buildings over 11m in England. This includes:

• Estimates of the number of buildings that have or had unsafe cladding to be remediated in a government remediation programme

• Estimates of the total cost to remediate buildings that have or had unsafe cladding by funding source

• Data relating to the Aluminium Composite Material (ACM) cladding programme – those highest risk buildings that are high-rise buildings with unsafe, ‘Grenfell-style’ ACM cladding

• Data relating to the Building Safety Fund, which funds the remediation of eligible high-rise residential buildings with other forms of unsafe cladding

• Data relating to the Cladding Safety Scheme, which funds the remediation of residential buildings over 11m in height with unsafe cladding

• Data relating to developer-led remediation, which reports on those buildings that developers have agreed to remediate

• Data on social buildings over 11m in height whose cladding remediation is funded by registered social housing providers

Estimated number of buildings with unsafe cladding

Information in this section shows MHCLG’s best estimates as at March 2026 and shows no update from the previous publication.

Key statistics:

MHCLG’s best estimates, as of March 2026, are that there are between 5,900 and 7,400 residential buildings, containing dwellings, 11 metres and over in height that have or had unsafe cladding requiring work in England. This equates to an estimated 8-14% of the residential building stock, containing dwellings, over 11 metres in England.

Of these:

• An estimated 2,800 - 3,700 buildings are 11-18m (5-9% of the estimated 39,000 - 59,000 11-18m buildings)

• An estimated 3,100 - 3,700 buildings are 18m+ (26-31% of the estimated 12,000 18m+ stock)

The estimates of the number of 11m+ buildings with unsafe cladding, as of March 2026, replace the estimates last published in June 2025. More information on the methodology is available in the Technical Note.

Estimates of buildings to be remediated in MHCLG’s remediation programmes:

MHCLG estimate there to be between 5,800 and 7,300 residential buildings, 11 metres over in height that have or had unsafe cladding that will be or have been remediated or mitigated as part of the department’s five remediation programmes, and therefore will be or are already monitored in the Building Safety Remediation monthly data release.

These figures differ from those in the Key Statistics section above because:

• 18m+ hotels, student accommodation or public buildings identified with unsafe ACM cladding are included in the estimates in this section, because these buildings are remediated through the ACM programme, but are excluded from the Key Statistics section above because the buildings do not contain dwellings. At the time the estimate was made there were 100 of these buildings

• The estimated number of 11m+ buildings which are assumed to be remediated privately, outside of one of the department’s remediation programmes, are included in the Key Statistics section above but excluded from the estimates in this section

Of these:

• An estimated 2,700 - 3,600 buildings are 11-18m

• An estimated 3,100 - 3,700 buildings are 18m+

Table 1: Estimated number of residential buildings with unsafe cladding expected to be remediated or mitigated as part of MHCLG’s remediation programmes, over 11 metres with unsafe cladding, by height, England, March 2026. These figures include non dwelling 18m+ buildings with unsafe cladding, and excludes buildings assumed to be remediated outside of a remediation programme. Totals do not sum due to rounding.

Height	Low Estimate	High Estimate
11-18m	2700	3600
18m+	3100	3700
Total 11m+	5800	7300

Table 2: Estimated proportion of buildings with unsafe cladding expected to be remediated or mitigated in a government remediation programme that are currently monitored in a government remediation programme, end of July 2026. Proportions are calculated from unrounded estimates so may not be derivable from rounded estimates in the data release.

Height	Number of buildings currently monitored	As a proportion of the low estimate	As a proportion of the high estimate
11-18m	2088	77%	58%
18m+	2609	83%	71%
Total 11m+	4697	81%	64%

As at the end of July 2026, MHCLG is monitoring the remediation progress of an estimated 64-81% of residential buildings with unsafe cladding expected to be remediated or mitigated in the department’s remediation programmes. More information on the remediation progress of buildings MHCLG are currently monitoring can be found in the Overall Remediation section of the data release.

These figures include buildings that have already completed remediation or mitigation of unsafe cladding.

Estimated cost of external wall system remediation of 11m+ residential buildings in England

Information in this section shows MHCLG’s best estimates as at March 2025 and remains unchanged from the previous publication.

Key statistics:

As of March 2025, MHCLG estimates that it will cost between £11.8bn and £22.7bn to remediate residential buildings, containing dwellings, 11 metres and above in height that have or had unsafe cladding in England.

Of this total estimated capital cost:

• An estimated £6.7bn - £15.2bn will have been funded by government once all works have been completed (56% - 67% of the total capital costs)

• An estimated £5.2bn - £7.4bn will have been funded by non-government actors once all works have been completed (33% - 44% of the total capital costs). This includes developers, registered providers of social housing and other actors

These costs relate to buildings which will be or have been remediated or mitigated as part of the department’s five remediation programmes. The costs also include an estimated number of 11m+ buildings which are assumed to be remediated privately, outside of one of the department’s remediation programmes. The costs estimates relate to the estimated number of buildings requiring remediation and accessing government funding as of March 2025. They include the estimated cost of works to-date as well as future works. The estimates account for the change in funding eligibility criteria where social landlords will now receive equal access to government remediation funding as private landlords. They exclude costs which fall outside the scope of remediating buildings 11 metres and above in height that have or had unsafe cladding in England.

These estimates have not been updated to reflect the updated estimates, as of March 2026, of the number of 11m+ buildings with unsafe cladding. The cost estimates will be updated in the future.

These estimates represent our current best estimates and will be subject to change as more information becomes available. They update estimates previously published in the National Audit Office (NAO) report “Dangerous cladding: the government’s remediation portfolio” in November 2024.

More information on the methodology is available in the Technical Note.

Table 3: Estimated capital cost of external wall system works to residential buildings over 11 metres with unsafe cladding to be, and which have been, remediated or mitigated, by funding source, England, March 2025, £bn (nominal terms, nearest £0.1bn).

Funding Source	Low Estimate	Central Estimate	High Estimate
Government Programmes	6.7	8.9	15.2
Non-government actors	5.2	6.1	7.4
Total	11.8	15.1	22.7

Table 4: Estimated proportion of capital costs of external wall system works to buildings over 11 metres with unsafe cladding expected to be, and which have been, remediated or mitigated, by funding source, England, March 2025.

Funding Source	Low Estimate	Central Estimate	High Estimate
Government Programmes	56%	59%	67%
Non-government actors	44%	41%	33%
Total	100%	100%	100%

Funding sources available to MHCLG for remediation:

It is estimated that, as of March 2025, MHCLG will have £9.2bn available to fund the remediation of external wall system defects.

This includes:

• a £5.2bn Exchequer contribution

• an estimated £0.7bn in refunds from developers

• a £3.4bn Building Safety Levy revenue target

These estimates are as of end March 2025 and have not been updated since their initial publication. As cost estimates continue to be updated, the Levy revenue target will be reviewed and adjusted such that funding available for remediation aligns to government expenditure.

Overall remediation progress

Figure 3: 2,551 residential buildings (54% of identified buildings) have started or completed remediation on unsafe cladding, of which 1,833 (39% of identified buildings) have completed remediation works.

Table 5: Remediation progress for 11m+ buildings identified with unsafe cladding which are in the ACM programme, eligible for the Building Safety Fund and the CSS, remediated under the developer remediation contract and self-funded by registered providers of social housing, England, end of July 2026.

Remediation Stage	Number of buildings	Percentage	Cumulative Number	Cumulative Percentage
Remediation complete	1833	39%	1833	39%
Remediation underway	718	15%	2551	54%
In programme	2146	46%	4697	100%
Total	4697	100%	4697	100%

The in programme figures currently include 78 social self-funded buildings where their remediation status is unknown as registered providers are yet to provide remediation dates. We expect buildings with unknown remediation status to be confirmed in coming months as further data is collected through engagement with Homes England.

Overall remediation: key statistics

Of the 4,697 residential buildings 11 metres and over in height with unsafe cladding the department is monitoring, as of the end of July 2026:

• 1,833 buildings (39%) have completed remediation, including those awaiting building control sign off

• 718 buildings (15%) have started remediation

• 2,146 buildings (46%) have not started remediation

Since the end of June 2026:

• The department is monitoring the remediation progress of 228 more buildings.

• 172 more buildings are known to have started or completed remediation, and 152 more buildings are known to have completed remediation.

• The increase in the number of buildings reported on is predominantly due to the inclusion of 194 more social self-funded buildings. 146 of these previously couldn’t be included in our reporting due to missing information. This information has now been provided to the department so these buildings can be included in our reporting. The remaining 48 have been newly added to the National Remediation Database (NRD) as social self-funded buildings this month. The majority of the 194 buildings are reported to have already completed remediation.

There are an estimated 250,000 dwellings in the occupied private and social sector 11m+ residential buildings with unsafe cladding that the department are monitoring. Of these an estimated 111,000 dwellings are in buildings that have completed remediation, and an estimated 35,000 additional dwellings are in buildings that have started remediation. An estimated 104,000 dwellings are in buildings that have not started remediation.

Figure 4: Progress of remediating unsafe cladding differs across the programmes and monitoring routes due to the differing maturity of the programmes.

Overall remediation by height

Figure 5: 62% of the 18m+ buildings the department is monitoring the remediation progress of have started or completed remediation on unsafe cladding, compared with 45% of 11-18m buildings.

Overall remediation by tenure

Figure 6: 58% of the social buildings the department is monitoring the remediation progress of have started or completed remediation on unsafe cladding, compared with 50% of the private buildings.

An interactive map showing remediation progress for all local authorities with over 10 buildings monitored with unsafe cladding can be found in the Maps section of the accompanying dashboard.

ACM remediation

Information in this section is correct as at 30 July 2026 and shows a monthly update from the previous publication.

Figure 7: 97% of the 516 identified ACM clad high-rise buildings have started or completed remediation, with 95% having had their ACM cladding removed and 93% having completed remediation, including those awaiting building control sign-off.

ACM Remediation: key statistics

As of 30 July 2026, the department has identified 516 high-rise residential and publicly owned buildings identified with ACM cladding systems unlikely to meet Building Regulations, no change since the end of June.

• 478 buildings (93% of all buildings) have completed ACM remediation – an increase of one since the end of June. Of these, 458 buildings (89% of all buildings) have received building control sign off – no change since the end of June

• 502 buildings (97% of all buildings) have started or completed ACM remediation – an increase of two since the end of June. Of these, 490 buildings (95% of all buildings) have removed ACM cladding – an increase of two since the end of June

There are an estimated 30,200-33,400 dwellings in private and social sector buildings that have completed remediation, and a further 2,400-2,500 dwellings in occupied private and social sector buildings that have yet to be remediated.

Driving ACM remediation forward

There are 14 buildings yet to start ACM remediation (3% of all buildings) - a decrease of two since the end of June. Two buildings are vacant so do not pose a risk to resident safety.

Table 8: Enforcement action and forecast start dates for occupied high-rise buildings yet to start ACM remediation, 30 July 2026

Occupied buildings that have:	Undergone enforcement action	Undergone enforcement action supported by Joint Inspection Team	Forecast start available	Forecast to start by the end of September 2026
Total	6	3	10	2

Of the 12 high-rise occupied buildings yet to start ACM remediation:

• Two buildings are forecast to start works by the end of September 2026, and one of these has had local authority enforcement action taken against it

• An additional eight buildings are forecast to start works by the end of 2027, and four of these have had local authority enforcement action taken against them

• One building without a forecast start date has had local authority enforcement action taken against it

• The remaining building has been determined as in scope of the ACM monitoring programme in 2026, and the department continues to engage with building owners to ensure remediation is progressed.

These forecast estimates are based on information provided by building owners and agents and may change as further information is received. These estimates can also change as a result of buildings being newly identified. The department continues to engage with building owners to start remediation works on site as soon as possible, and will continue to support local authorities and fire and rescue services in the use of their enforcement powers.

Figure 8: 98% of buildings are forecast to have started or completed ACM remediation works by the end of September 2026.

ACM remediation progress by year of identification

Figure 9: 99% of buildings identified at 31 December 2024 have started or completed remediation compared with 97% of all buildings in the programme.

Since 31 December 2021, 35 further high-rise residential buildings have been identified with ACM cladding systems unlikely to meet Building Regulations and have moved into scope of the Building Safety Programme. Of these, six buildings were identified in 2022, eight buildings were identified in 2023, 10 buildings were identified in 2024, eight buildings were identified in 2025 and three buildings were identified in 2026.

BSF remediation: key statistics

As at 30 July 2026, 639 buildings were assessed as eligible and are proceeding with an application for funding from the Building Safety Fund. The remaining 3,072 buildings registered with the fund are either ineligible (1,118), withdrawn (1,634), have transferred to the Cladding Safety Scheme (307), or have been retained by the Cladding Safety Scheme (13).

Of the 3,071 buildings that registered with the Building Safety Fund and are not currently proceeding with an application for funding, 461 buildings which were assessed as eligible have been transferred to developers.

As at 30 July 2026, 307 buildings have been transferred to the Cladding Safety Scheme for their remediation and are progressing through the CSS fund, no change since reported at the end of June. Of these, 303 buildings had not started remediation works before transferring to the CSS.

The number of buildings reported as transferred from the BSF to the CSS in this section of the data release may not be the same as the number of eligible CSS buildings that have transferred from the BSF in the CSS section of the data release. This is because different programmes may define buildings differently due to how they operate. Five buildings have also withdrawn from the CSS since transferring from the BSF.

Of the 639 buildings proceeding with an application for funding in the Building Safety Fund:

• 156 buildings (24%) are remaining in the fund with developers set to reimburse the cost of remediation

• Zero buildings (0%) are anticipated to be transferred to developers

Of the 639 buildings proceeding with an application for funding, 99 buildings have been assessed with a Fire Risk Appraisal for External Walls (FRAEW), and 540 have been assessed under the BSF 2020 CAN criteria. It is possible for a building to submit a new application to the fund after having completed remediation, if it originally applied under the BSF 2020 CAN criteria. Therefore, buildings could be double counted. As of 30 July 2026 one building had undertaken remediation work from both application periods, so is double counted. Further details are available in the Technical Note.

Of the 639 buildings proceeding with an application for funding, 562 buildings (88%) have either started or completed remediation works – no change since the end of June.

Of the 562 buildings that have started or completed remediation as at 30 July 2026:

• 75 buildings (12% of all buildings) have started remediation

• 487 buildings (76% of all buildings) have completed remediation – an increase of five since the end of June. Of these, 389 buildings (61% of all buildings) have received building control sign off

There are 77 eligible buildings proceeding with an application for funding that have not started remediation, of which:

• 66 (10% of all buildings) have remediation plans in place

• 11 (2% of all buildings) have reported an intent to remediate

There are an estimated 53,000 dwellings in buildings that are eligible and proceeding with an application for funding in the BSF.

BSF remediation progress over time

Figure 12: 17 more buildings proceeding with an application for funding in the BSF have started or completed remediation since the end of July 2025

Since the end of July 2025:

• 135 fewer eligible buildings are proceeding with an application for funding from the Building Safety Fund

• 17 more eligible buildings have started or completed remediation

• 63 more eligible buildings have completed remediation

Cladding Safety Scheme

Information in this section is correct as at 31 July 2026 and shows a monthly update from the previous publication.

Figure 14: There are 3,691 buildings at different stages of the Cladding Safety Scheme, including 1,352 buildings with live applications and 1,438 eligible buildings, of which 396 buildings have started or completed works, with 127 having completed works.

Cladding Safety Scheme: Key statistics

As at the end of July 2026, there were 3,691 buildings in the different stages of the Cladding Safety Scheme (1,438 eligible buildings and 2,253 pre-eligible buildings). Of the 2,253 pre-eligible buildings:

• 901 buildings are in the pre-application stage

• 1,352 buildings have a live application and are progressing through the eligibility stages

There are 1,438 eligible buildings as at the end of July 2026, an increase of 43 since the end of June. None of the newly eligible buildings this month have been transferred from the BSF. In total, 280 of the eligible buildings in the CSS have been transferred from the BSF.

The number of eligible CSS buildings reported as transferred from the BSF to the CSS in this section of the data release may not be the same as the number of buildings that have transferred from the BSF to the CSS in the BSF section of the data release. This is because different programmes may define buildings differently due to how they operate. Five buildings have also withdrawn from the CSS since transferring from the BSF.

Of the 1,438 eligible buildings:

• 1,353 buildings (94% of eligible buildings) have signed Grant Funding Agreements (GFA) - an increase of 84 since the end of June

• Of these, 1,199 buildings (83% of all eligible buildings) have received a pre-tender support payment – an increase of 112 since the end of June

• 396 buildings (28% of all eligible buildings) have started or completed remediation works on site – an increase of 15 since the end of June

• Of these, 127 buildings (9% of all eligible buildings) have completed remediation works on site, including those awaiting building control sign-off – an increase of eight since the end of June

Four eligible buildings are in Northern Ireland, with the remainder in England.

Height breakdown

Figure 15: 37% of eligible 11-18m buildings in the CSS have started or completed remediation, compared with 13% of eligible 18m+ buildings.

Tenure breakdown

Figure 16: 22% of eligible social sector buildings in the CSS have started or completed remediation, compared with 32% of eligible private sector buildings.

Social housing funding eligibility criteria changed in June 2025, allowing more social housing buildings to access government funding from the CSS. Therefore, we expect more eligible social buildings will appear on the social bar of this graph over time. As of 31 July 2026, of the pre-eligible live applications to the CSS, 85% of the applications are social, 13% are private, and for 2% their tenure is currently unknown.

Developer-led remediation

Information in this section received by developers is correct as at 30 April 2026 and remains unchanged from the previous publication.

The estimates in this section include some buildings which are also included in other sections of this data release e.g., those reported under the following sections: ‘ACM Remediation’, ‘Building Safety Fund’ and ‘Cladding Safety Scheme’.

Figure 17: 48% of buildings in the developer remediation contract have either started or completed remediation works on life-critical fire safety risks, with 23% having completed remediation works, including those awaiting building control sign-off.

Table 12: Remediation status of buildings requiring works under the developer remediation contract, 31 July 2026. Percentages may not sum to 100% due to rounding.

Developer remediation: key statistics

The estimates in this section are based on a combination of self-reported data submitted by developers and information that has been imputed from Building Safety Fund (BSF), Cladding Safety Scheme (CSS) and ACM programme data. A building is identified with life-critical fire safety defects if at least one of the following is true:

• The developer has self-reported that works are (or were) required on the building

• The developer has reported a remediation status of planned, started or complete

• The building is eligible for funding in the BSF, Cladding Safety Scheme (CSS) or is being monitored under the ACM programme (including buildings developers have agreed to reimburse taxpayers for)

• The building has had money paid out by the BSF or ACM remediation funds

Furthermore, where a building has been identified with life-critical fire safety defects but the developer has not reported a defect type in the question ‘What do the issues relate to’ it is assumed that the defect type relates to cladding.

Other data, unless otherwise stated, is based on self-reported data by developers in their latest data report.

From February 2026, if a developer’s buildings will be monitored solely via government remediation schemes, we use the developer’s most recent data return held by MHCLG to report the number of buildings for which the developer is responsible under the Developer Remediation Contract, and we use relevant data from the government scheme(s) to impute whether a building requires works, the defect type, remediation status and cost of works.

As at 31 July 2026, 53 developers have signed the developer remediation contract. There are 4,738 buildings covered by the developer remediation contract. Of these, 2,621 have been identified as having life-critical fire safety defects that developers are obligated to remediate or pay to remediate – an increase of seven since the June data release.

Of the 2,621 buildings identified as having life-critical fire safety risks:

• 596 (23%) are reported to have completed remediation – no change since the June data release. Of the 596 buildings that are reported to have completed remediation, 487 buildings (19% of all buildings with defects) are reported to have received building control sign-off

• 1,264 (48%) are reported to have started or completed remediation – no change since the June data release

• 383 (15%) are reported to have not started remediation but have plans in place – no change since the June data release

• 974 buildings (37%) have not started and have no plans in place - an increase of seven since the June data release

Although information from developers is received quarterly, these statistics are subject to change and are updated monthly as information from other programmes which relate to remediation is updated monthly.

The 2,621 buildings identified as requiring remediation have an estimated cost of remediation of around £4.3 billion. This is an increase of £13m compared to the June data release. This cost is based on the self-reported cost of works in the developer data report. However, if the cost is not known it is imputed based on the average known reported cost by developers by height band of building.

There are an estimated 168,000 dwellings in buildings with defects that developers are committed to remediate. Of these, there are an estimated 89,000 dwellings in buildings that are reported as having either started or completed remediation works.

Based on start and completion dates reported by developers, 722 buildings which have not yet started are reportedly expected to start works between 1 May 2026 and 30 April 2027, and 392 buildings which have not yet completed are reportedly expected to complete their remediation between 1 May 2026 and 30 April 2027.

451 buildings have transferred from the Building Safety Fund to developers, no change since the June data release. From July 2026 we have made a methodological change to these statistics. Previously, whether a building had been identified with life-critical fire-safety defects or not relied on developer self-reported data and other programme data. From July 2026 this now relies on developer self-reported data only:

• 71 (16%) have completed remediation - no change since the June data release. Of these 71, 48 buildings (11% of all buildings) are reported to have received building control sign-off

• 224 (50%) have started or completed remediation – no change since the June data release

• 89 (20%) are reported to have not started remediation but have plans in place – no change since the June data release

• 79 (18%) are reported to have not started remediation and have no plans in place – a decrease of four since the June data release due to a methodological change

• 59 (13%) have not been identified by developers as having life-critical fire-safety defects – an increase of four since the June data release due to a methodological change

The 451 buildings in the developer remediation contract differs from the 461 reported in the Building Safety Fund section of the data release, due to developers defining buildings differently to in the Building Safety Fund. The same building structures are included in both sections of the release.

Height breakdown

Cladding defects

The estimates in this section are based on a combination of self-reported data submitted by developers and information that has been imputed from Building Safety Fund (BSF), ACM and CSS programme data (please see above for further details).

Where a building has been identified with life-critical fire safety defects but the developer has not reported a defect type in the question ‘What do the issues relate to’ it is assumed that the defect type relates to cladding.

Some remediation being undertaken by developers on buildings with life-critical fire safety risks relate to non-cladding defects. When excluding buildings reported to have only non-cladding defects, there are 1,833 buildings which developers have reported as having unsafe cladding – an increase of eight since the June data release. Of these:

• 566 (31%) are reported to have completed remediation– no change since the June data release. Of the 566 buildings that are reported to have completed remediation, 434 buildings (24% of all buildings with defects) are reported to have received building control sign-off

• 862 (47%) are reported to have started or completed remediation – no change since the June data release

• 387 (21%) are reported to have not started remediation but have plans in place – no change since the June data release

• 584 (32%) are reported to have not started remediation but have plans in place – an increase of eight since the June data release

These estimates are subject to change each month due to the monitoring of buildings under the developer remediation contract in other remediation programmes.

Self-reported and developer-led remediation

The figures reported for developers above combine information received directly from developers as well as information held by the department from other programmes which relate to remediation. This is to help better estimate a figure for buildings requiring remediation under the developer remediation contract. The figures reported above will also include buildings which are being remediated solely under a government remediation scheme, for which the developer will reimburse taxpayers.

The estimates in this section report on buildings which have been self-reported by developers as requiring remediation to life-critical fire safety risks. Furthermore, this section reports on buildings which are being remediated by the developer directly, rather than being remediated through a government fund and being reimbursed to taxpayers. However, some buildings being remediated under a government remediation programme will be included if other relevant fire safety defects have been found, which were not eligible for a government remediation programme and which the developer is remediating themselves. Developers have self-reported that 2,456 buildings require life-critical fire safety remediation, which will be directly remediated by the developer, no change since the June data release.

Buildings that are being remediated in the BSF, ACM or CSS programme, but are also reported to have other non-EWS life-critical fire safety defects by the developer will be included in these statistics. Of these 2,456 buildings being directly remediated by the developer:

• 511 buildings (21%) have completed remediation, no change since the June data release. Of these, 417 buildings (17% of all buildings with defects) are reported to have received building control sign-off

• 1,145 buildings (47%) have started or completed remediation, no change since the June data release

• 383 buildings (16%) have not started remediation but have a plan in place, no change since the June data release

• 928 buildings (38%) have not started and have no plans in place, no change since the June data release

Further information on the progress developers have made regarding the buildings they’ve reported on is available in the accompanying management information tables and quarterly Developer remediation contract data release. From August 2025 these include an update against the commitments set out in the joint plan to accelerate developer-led remediation and improve resident experience, which was published alongside the department Remediation Acceleration Plan (RAP).

Additionally, alongside the Building Safety Remediation Data Release, MHCLG publishes a ‘developer progress chart’ which allows you to compare the progress developers have made on determining whether works are required on buildings they are responsible for, as well as progress being made on buildings requiring works that have started on site. This chart represents the self-reported information shown above and is published in the accompanying dashboard.

Social housing self-funded remediation

Data quality

Homes England are continuing to work with registered providers to review records of their 11m+ buildings which have or had unsafe cladding to the National Remediation Database (NRD). While this work is underway, fluctuations in the remediation progress figures for social buildings where registered providers are self-funding cladding remediation is expected. Once this work is complete, we expect to be able to provide more accurate and frequent information on social housing remediation progress. Further information on the data collection of social self-funded buildings is available in the Technical Note.

Social Housing remediation: Key statistics

Figure 19: 77% of social self-funded buildings reported to have unsafe cladding have started or completed remediation works, with 64% (of identified buildings) having completed remediation works.

Table 13: Remediation status of social self-funded buildings with unsafe cladding, 31 July 2026.

Remediation Stage	Number	Percentage	Cumulative Number	Cumulative Percentage
Remediation completed	474	64%	474	64%
Works started	100	13%	574	77%
Works not started	90	12%	664	89%
Remediation progress currently unknown	78	11%	742	100%
Total	742	100%	742	100%

As at 31 July 2026, there are 742 11m+ social buildings identified with unsafe cladding which registered providers are self-funding the remediation of. These figures include social buildings that registered providers reported to be self-funding the cladding remediation of in the NRD, that were not identified in another remediation programme, and 19 social buildings monitored in the ACM programme where registered providers have self-funded ACM remediation.

The number of 11m+ social buildings identified with unsafe cladding which registered providers are self-funding the remediation of has increased by 186 since the end of June 2026. This increase is predominantly driven by 146 social buildings which previously couldn’t be included due to missing information. This information has now been provided in the department’s data from the NRD and can be reported on in the data release. Additionally, 48 buildings have been newly added to the NRD as social self-funded buildings this month. Eight buildings have been removed from our reporting as they are no longer reported in the NRD.

Of these 742 11m+ social buildings where registered providers are self-funding remediation:

• 474 (64%) are reported to have completed remediation – an increase of 138 since the end of June 2026

• 574 (77%) are reported to have started or completed remediation – an increase of 156 since the end of June 2026

• 90 (12%) are reported to have not started remediation – an increase of 15 since the end of June 2026

• The remediation status of 78 (11%) buildings is currently unknown as registered providers are yet to provide remediation dates on the NRD – an increase of 15 since the end of June. We expect buildings with unknown remediation status to be confirmed in coming months as further data is collected

Enforcement

Information in this section is correct as at 24 July 2026 and shows a monthly update from the previous publication.

This section includes local authority enforcement action on buildings 11 metres or over in height. Up until June 2024 only enforcement action taken on buildings over 18m in height was reported on.

Local authority enforcement action: key statistics

As at 24 July 2026, enforcement action has been, or is being, taken under the Housing Act against 921 buildings over 11m with suspected unsafe cladding - an increase of 15 since the end of June data release . Some of these buildings will have been found to be safe, and others may not have unsafe cladding but other building safety defects. The department has monitored or is currently monitoring the cladding remediation progress of 47% of these 921 buildings, including those which have completed remediation.

191 of the 921 buildings where enforcement action has been, or is being taken, have had 194 inspections with Joint Inspection Team support – an increase of four inspections since the end of June data release.

Of the 921 buildings where a local authority had undertaken an inspection, we are aware of the following HHSRS ratings in relation to fire hazards only:

• 150 had a Category 1 rating

• 676 had a Category 2 rating

As several buildings have now had two or more inspections, from August 2024, only the most recent inspection’s category rating is reported on, as this is used to gauge the risks of the buildings in each Local Authority’s portfolio. Additional inspections are still reported as enforcement action.

Of the 921 buildings, we are aware that at least 277 improvement notices, 123 hazard awareness notices and 1 prohibition order have been served to date. Some buildings may have received multiple notices. We understand that 64 of the improvement notices have been subject to appeals.

Accompanying dashboard

An additional interactive dashboard showing the information in this release is available.

Accompanying tables

Additional management information tables are available.

The tables provide data on:

• The estimated number of residential buildings 11 metres and over with unsafe cladding and the estimated cost to remediate them

• the remediation progress of high-rise (18 metres and over) residential buildings identified with unsafe Aluminium Composite Material (ACM) cladding systems

• the remediation progress of high-rise residential buildings with unsafe non-ACM cladding systems that are pursuing successful applications from their Building Safety Fund (BSF) Registration

• data on buildings in the Cladding Safety Scheme (CSS)

• the remediation progress of buildings covered by the developer remediation contract, including a developer-by-developer breakdown
