Overall remediation

As at the end of August 2024, there are 4,771 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 141 since the end of July 2024. This increase is larger than previous recent months as a result of quarterly updates from social housing providers and developers. The majority of the increase is due to social housing providers and developers identifying more buildings with cladding defects, along with some further buildings being identified for the three other remediation programmes.

At the beginning of 2023, the department was monitoring the remediation progress of high-rise buildings with ACM cladding systems unlikely to meet Building Regulations and buildings progressing in the Building Safety Fund. Throughout 2023, the department started monitoring the remediation progress of buildings in the Cladding Safety Scheme, developer remediation contract and reported by registered providers of social housing. From July 2024 social housing buildings that had completed remediation independently of government funding and monitoring schemes before March 2024 have been included in the reporting. These changes in scope have largely driven the reporting of an additional 3,431 buildings with unsafe cladding since the end of August 2023.

Overall, 2,377 buildings (50%) have either started or completed remediation works. Of these, 1,392 buildings (29%) have completed remediation works.

Figure 1: Of the 4,771 buildings identified with unsafe cladding, 2,377 (50%) have started or completed remediation works, of which 1,392 (29%) have completed remediation works. This includes remediation progress on high rise (18m+) and mid-rise (11-18m) buildings in height.

Note: Up to October 2023 combined remediation progress in the Building Safety Fund (BSF) and ACM programme is shown. Between June 2023 and September 2023 there was a decrease in the number of buildings largely due to eligible buildings in the Building Safety Fund transferring to developers under the developer remediation contract. These buildings are then included in the reporting under the developer remediation contract from October onwards. From October 2023 onwards combined remediation progress is shown across the BSF, ACM programme, Cladding Safety Scheme, developer remediation contract and as reported by registered providers of social housing. The total number of buildings does not sum to the total number of buildings reported in each respective section of the data release due to crossover between schemes.

The majority of the increase in completions shown between October and November 2023 is due to a change in methodology when assigning remediation statuses for buildings that crossover between multiple schemes.

The increase in the number of reported completions between May and June 2024 is largely due to a change in methodology in reporting social housing sector remediation, which from June 2024 includes social housing buildings that had completed remediation independently of government funding and monitoring schemes before March 2024.

ACM remediation – monthly update (as at end August 2024) since previous publication

As at 31 August 2024 of the 503 high-rise (18 metres and over in height) residential and publicly owned buildings with ACM cladding systems, unlikely to meet Building Regulations, 490 (97%) have either started or completed remediation works, an increase of two since the end of July.

Of these, 442 buildings (88%) have completed ACM remediation, including those awaiting building control sign-off, an increase of four since the end of July.

There are 13 buildings yet to start ACM remediation (3% of all buildings), an increase of two since the end of July. One building is vacant so does not pose a risk to resident safety, seven occupied buildings have forecast start dates, two further buildings have had local authority enforcement action taken against them, one building came into scope in April 2024, and the remaining two buildings came into scope in August 2024.

Building Safety Fund (BSF) – monthly update (as at end August 2024) since previous publication

As at 31 August 2024, of the 805 high-rise (18 metres and over in height) residential buildings proceeding with an application for funding through the Building Safety Fund, 191 buildings (24%) have started remediation works and 326 buildings (40%) have completed remediation on unsafe non-ACM cladding, including those awaiting building control sign-off.

Overall, 517 high-rise buildings (64%) in the BSF have either started or completed remediation works on non-ACM cladding, a decrease of one since the end of July. Of these, 326 buildings (40% of buildings) have completed remediation works, an increase of 5 since the end of July.

Cladding Safety Scheme (CSS) – monthly update (as at end August 2024) since previous publication

As at 31 August 2024, 405 buildings 11 metres and over in height have been assessed as eligible for the Cladding Safety Scheme (including 111 buildings that have transferred from the BSF), an increase of 26 since the end of July. All have either signed grant funding agreements or are in the process of doing so and are actively procuring works in the market. 10 buildings have started remediation work on site, an increase of two since the end of July.

The CSS continues to investigate and pull in potentially eligible buildings. There are a further 1,315 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, 392 buildings are progressing through eligibility checks, and 923 buildings are in the pre-application stage.

This is in addition to over 4,000 buildings in the pipeline that are being investigated, and where within programme parameters, are being brought into the pre- application process.

Developer remediation – data received from developers as at 31 July 2024, data received from other programmes relating to developer-led remediation is as at 31 August 2024

As at 31 August 2024, 1,626 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 61 since reported in the July data release.

Of these, developers reported that 769 (47%) have either started or completed remediation works, an increase of 42 since reported in the July data release. Of these, 410 (25% of buildings) are reported to have completed remediation works, an increase of 48 since reported in the July data release.

When excluding buildings reported with only non-cladding defects, there are 1,449 buildings which developers have reported as having unsafe cladding, of which 715 (49%) are reported to have started or completed remediation, including 381 (26% of buildings) which are reported to have completed remediation.

Social housing sector – data received from Registered Providers of social housing as at 30 June 2024, data received from other programmes relating to social housing sector remediation is as at 31 August 2024

As at 31 August 2024, 2,507 social buildings 11 metres and over in height have been identified as having life-critical fire-safety cladding defects. These have been identified using survey data submitted by Registered Providers of social housing and data on buildings the department is monitoring under other government programmes (ACM programme, BSF, CSS and Developer Remediation contract).

Of these, 1,268 (51%) have started or completed remediation works, an increase of 60 since reported in the July data release. Of these, 703 (28% of buildings) have completed remediation, an increase of 40 since reported in the July data release.

Enforcement – monthly update (as at 23 August 2024) since previous publication

As at 23 August 2024, local authority enforcement action has been, or is being, taken under the Housing Act 2004 against 430 buildings over 11m with unsafe cladding, an increase of 12 since the end of July.

Introduction

This Data Release provides data on:

• 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 remediation of high-rise residential buildings with non-ACM cladding systems assessed as eligible for funding from the Building Safety Fund
• Progress with the applications for and remediation of medium-rise (11 – 18 metres in height) residential buildings in England, and Northern Ireland, and high-rise residential buildings outside of London 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
• Enforcement action taken by local authorities against high-rise residential buildings with unsafe cladding under the Housing Act 2004.

From October 2023 onwards the Building Safety Remediation data release includes data on buildings in the Building Safety Fund, Cladding Safety Scheme, developer remediation contract and reported by registered providers of social housing, as well as high-rise buildings with ACM cladding systems. Previous versions of the data release have only included data on high-rise buildings with ACM cladding systems unlikely to meet Building Regulations, with data on buildings in the Building Safety Fund published separately.

Since April 2023, the management information tables published alongside the data release have included a table on combined remediation progress in the ACM programme and BSF, accounting for buildings that are eligible for both programmes.

In Figure 1 in this data release, up to October 2023 the data includes the combined remediation progress in the ACM programme and BSF. From October 2023 onwards, the data in Figure 1 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.

The figures in this publication are correct as at the specified dates. Remediation progress on the ACM programme, BSF and CSS will be updated monthly, and remediation progress on the developer remediation contract and registered providers of social housing will be updated quarterly.

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:

• 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 residential buildings over 11m in height that are the responsibility of registered social housing providers.

Overall remediation progress

Overall remediation: key statistics

Of the 4,771 residential buildings 11 metres and over in height with unsafe cladding the department is monitoring, as at 31 August 2024:

• 1,392 buildings (29%) have completed remediation, including those awaiting building control sign off
• 985 building (21%) have started remediation
• 2,394 buildings (50%) have not started remediation

Since the end of July 2024:

• The department is monitoring the remediation progress of 141 more buildings.
• 78 more buildings are known to have started or completed remediation, and 42 more buildings are known to have completed remediation.

Since the end of August 2023:

• The department is monitoring the remediation progress of 3,431 more buildings, largely due to the opening of new programmes and new data reporting on the CSS, developer-led remediation, and from social housing registered providers.
• 1,538 more buildings are known to have started or completed remediation, of which 857 more buildings are known to have completed remediation.

There are an estimated 258,000 dwellings in the occupied private and social sector 11m+ residential buildings with unsafe cladding that the department are monitoring. Of these an estimated 87,000 dwellings are in buildings that have completed remediation, and an estimated 55,000 additional dwellings are in buildings that have started remediation. An estimated 116,000 dwellings are in buildings that have not started remediation.

ACM Remediation: key statistics

As of 31 August 2024, the department has identified 503 high-rise residential and publicly owned buildings identified with ACM cladding systems unlikely to meet Building Regulations, an increase of four since the end of July.

• 442 buildings (88% of all buildings) have completed ACM remediation – an increase of four since the end of July. Of these, 412 buildings (82% of all buildings) have received building control sign off – an increase of one since the end of July.
• 490 buildings (97% of all buildings) have started or completed ACM remediation – an increase of two since the end of July. Of these, 473 buildings (94% of all buildings) have removed ACM cladding – an increase of two since the end of July.

There are an estimated 26,400 – 29,600 dwellings in private and social sector buildings that have completed remediation, and a further 5,000 – 5,100 dwellings in occupied private and social sector buildings that have yet to be remediated.

Driving ACM remediation forward

There are 13 buildings yet to start ACM remediation (3% of all buildings) – an increase of two since the end of July. One building is vacant so does not pose a risk to resident safety.

Table 3: Enforcement action and forecast start dates for occupied high-rise buildings yet to start ACM remediation, 31 August 2024

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

• Two buildings are forecast to start works by the end of December 2024.
• Five additional buildings are forecast to start works in 2025 and four of these have had local authority enforcement action taken against them.
• Two further buildings without a forecast start date have had local authority enforcement action taken against them.
• One building was newly in scope of the ACM monitoring programme in April 2024.
• The remaining two buildings are newly in scope of the ACM monitoring programme in August 2024.

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: 97% of buildings are forecast to have started or completed ACM remediation works by the end of September 2024.

ACM remediation progress by year of identification

Figure 9: 99% of buildings identified at 31 December 2022 have started or completed remediation compared to 97% of all buildings in the programme.

Since 31 December 2021, 22 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 in 2023 and eight in 2024.

BSF remediation: key statistics

As at 31 August 2024, 805 buildings were assessed as eligible and are proceeding with an application for funding from the Building Safety Fund. The remaining 2,853 buildings registered with the fund are either ineligible (1,109), withdrawn (1,594), in review or have given insufficient evidence (25), or have transferred to the Cladding Safety Scheme (125).

Of the 2,853 buildings that registered with the Building Safety Fund and are not currently proceeding with an application for funding, 452 buildings which were assessed as eligible have been transferred to developers.

As at 31 August, 125 buildings have transferred to the Cladding Safety Scheme for their remediation (where works have not yet started on site) and are progressing through the CSS process. 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 transferred buildings will go through CSS eligibility checks before buildings are included in the eligible CSS figures.

Of the 805 buildings proceeding with an application for funding in the Building Safety Fund:

• 171 buildings (21%) are remaining in the fund with developers set to reimburse the cost of remediation,
• Nine buildings (1%) are anticipated to be transferred to developers

Of the 805 buildings proceeding with an application for funding, 136 buildings have been assessed with a Fire Risk Appraisal for External Walls (FRAEW), and 669 have been assessed under the BSF 2020 CAN criteria. Further details are available in the technical note.

Of the 805 buildings proceeding with an application for funding, 517 buildings (64%) have either started or completed remediation works – a decrease of one since the end of July.

Of the 517 buildings that have started or completed remediation as at 31 August 2024:

• 191 buildings (24% of all buildings) have started remediation.
• 326 buildings (40% of all buildings) have completed remediation – an increase of five since the end of July. Of these, 210 buildings (26% of all buildings) have received building control sign off.

There are 288 eligible buildings proceeding with an application for funding that have not started remediation, of which:

• 130 (16% of all buildings) have remediation plans in place
• 158 (20% of all buildings) have reported an intent to remediate

There are an estimated 67,000 dwellings in buildings that are eligible and proceeding with an application for funding in the BSF.

BSF remediation progress over time

Figure 12: 92 more buildings proceeding with an application for funding in the BSF have started or completed remediation since the end of August 2023

Since the end of August 2023:

• 133 fewer eligible buildings are proceeding with an application for funding from the Building Safety Fund.
• 92 more eligible buildings have started or completed remediation, and 155 more eligible buildings have completed remediation.

BSF remediation by tenure

Figure 13: 65% of social sector buildings in the BSF, including buildings with a financial viability claim, have started or completed remediation compared to 64% of private sector buildings.

Social sector buildings receiving full government funding for their remediation due to financial viability claims were, up until May 2024, included in private sector buildings counts. Further detail is available in the accompanying technical note.

Cladding Safety Scheme

Information in this section is correct as at 31 August 2024 and shows a monthly update from the previous publication.

Figure 14: There are 1,720 buildings at different stages of the Cladding Safety Scheme, including 392 buildings with live applications and 405 eligible buildings, of which 10 buildings have started works.

Cladding Safety Scheme: Key statistics

As at the end of August 2024, there were 1,720 buildings in the different stages of the Cladding Safety Scheme (405 eligible buildings and 1,315 pre-eligible buildings). Of the 1,315 pre-eligible buildings:

• 923 buildings are in the pre-application stage.
• 392 buildings have a live application and are progressing through the eligibility stages.

There are 405 eligible buildings as at the end of August 2024, an increase of 26 since the end of July. None of the newly eligible buildings this month has been transferred from the BSF. In total, 108 of the eligible buildings in the CSS have been transferred from the BSF.

Of the 405 eligible buildings:

• 343 buildings (85% of eligible buildings) have signed Grant Funding Agreements (GFA) - an increase of 55 since the end of July
• Of these, 227 buildings (56% of all eligible buildings) have received a pre-tender support payment – an increase of 41 since the end of July
• 10 buildings have started remediation works on site – an increase of two since the end of July.

There are over 4,000 further buildings being investigated to establish whether they can start the pre-application process.

Three eligible buildings and two buildings with a live application are in Northern Ireland, with the remainder in England.

Height breakdown

Developer-led remediation

Information in this section received by developers is correct as at 31 July 2024 and shows a quarterly update from the previous publication. Information in this section received from other programmes that relate to developer-led remediation (where cladding remediation is being carried out in a government funded remediation programme and the developer will subsequently pay for the works) is correct as at 31 August 2024.

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’, ‘Cladding Safety Scheme’ and ‘Social Housing Sector’.

Figure 17: 47% of buildings in the developer remediation contract have either started or completed remediation works on life-critical fire safety risks, with 25% having completed remediation works.

Table 7: Remediation status of buildings requiring works under the developer remediation contract, 31 August 2024. Percentages may not sum to 100% due to rounding.

Developer remediation: key statistics

As at 31 August 2024, there are 4,668 buildings covered by the developer remediation contract. Of which, there are 1,626 buildings identified as having life-critical fire safety risks that will be remediated by developers. This is an increase of 61 compared to the 31 July 2024 Building Safety Data Release, which used data submitted by developers at the end of April 2024. The increase is due to pre-existing signatories identifying and reporting more buildings requiring works in their latest data return, which was submitted to MHCLG in August, for the quarter to the end of July 2024.

Of the 1,626 buildings identified as having life-critical fire safety risks:

• 410 (25%) are reported to have completed remediation– an increase of 48 since reported in the July data release. Of the 410 buildings that are reported to have completed remediation, 342 buildings (21% of all buildings) have received building control sign-off.
• 769 (47%) are reported to have started or completed remediation – an increase of 42 since reported in the July data release.
• 455 (28%) are reported to have not started remediation but have plans in place – an increase of 84 since reported in the July data release.

Although information from developers is received quarterly, these statistics are updated monthly as information from other programmes which relate to developer remediation is updated monthly. For further information about the previous quarterly update, see the May Building Safety Remediation data release.

The 1,626 buildings identified as requiring remediation have an estimated cost of remediation of around £3.3 billion. This is an increase of £0.1 billion since reported in the July data release, which is due to more buildings with defects being identified

There are an estimated 105,000 dwellings in buildings with defects that developers are committed to remediate. Of these, there are an estimated 50,000 dwellings in buildings that are reported as having either started or completed remediation works.

Based on start and completion dates reported by developers, 451 buildings are expected to start works and 361 buildings are expected to complete their remediation between 1 August 2024 and 31 July 2025.

Of the 1,626 buildings identified as requiring remediation, 441 have transferred from the Building Safety Fund, having been assessed as eligible during their application process. Of these 441 buildings:

• 39 (9%) have completed remediation - an increase of 10 since reported in the July data release. Of these 39, 25 buildings (6% of all buildings) have received building control sign-off.
• 141(32%) have started or completed remediation - an increase of 9 since reported in the July data release.
• 133 (30%) are reported to have not started remediation but have plans in place - an increase of 13 since reported in the July data release.

The 441 buildings in the developer remediation contract differs from the 452 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

Figure 18: 54% of the 18m+ buildings have started or completed remediation, compared to 39% of the 11-18m buildings.

Cladding defects

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 1,449 buildings which developers have reported as having unsafe cladding. Of these:

• 381 (26%) are reported to have completed remediation - an increase of 41 since reported in the July data release. Of these 381, 320 buildings (22% of all buildings) have received building control sign-off.
• 715 (49%) are reported to have started or completed remediation - an increase of 38 since reported in the July data release.
• 418 (29%) are reported to have not started remediation but have plans in place - an increase of 73 since reported in the July 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 information

The figures reported for developers above combine information received directly from developers as well as information held by the department regarding additional buildings that require or previously required remediation work to help better estimate a figure for buildings requiring remediation. Developers have self-reported that 1,480 buildings require remediation to life-critical fire safety risks and of those 1,357 buildings will be directly remediated by the developer, rather than remaining in government funds to be remediated and then reimbursed by the developer. Some buildings are being remediated in the BSF or ACM programme but have other non-EWS life-critical fire safety defects which are also included in these statistics. Of these 1,357 buildings being directly remediated by the developer:

• 247 buildings (18%) have completed remediation – an increase of 29 since reported in the July data release. Of these, 194 buildings (14% of all buildings) have received building control sign-off.
• 553 buildings (41%) have started or completed remediation – an increase of 55 since reported in the July data release.
• 429 buildings (32%) have not started remediation but have a plan in place – an increase of 82 since reported in the July 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.

Social Housing Sector

Information in this section received by Registered Providers of Social Housing is correct as at 30 June 2024. Information in this section received from other programmes that relate to social housing is correct as at 31 August 2024.

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’, ‘Cladding Safety Scheme’ and ‘Developer Remediation’.

From June 2024, the estimates in this section of the release include buildings which have been reported by Registered Providers to have completed remediation since 14 June 2017 but prior to the most recent assessment. They also include social buildings the department has identified in other remediation programmes as having unsafe cladding and are also being monitored in those programmes.

Figure 19: 51% of social buildings identified to have unsafe cladding have started or completed remediation works, with 28% (of identified buildings) having completed remediation works.

Remediation Stage	Number of buildings	Percentage	Cumulative Number	Cumulative Percentage
Remediation complete	641	26%	641	26%
Remediation complete – awaiting building control sign-off	62	2%	703	28%
Remediation started	565	23%	1268	51%
Remediation works planned	699	28%	1697	78%
Remediation plans unclear from survey	540	22%	2507	100%
Total	2507	100%	1626	100%

Social Housing remediation: key statistics

577 registered providers of social housing were invited to respond to this round of a survey on their 11m+ stock. 922 small registered providers were excluded from this round of the survey because they had indicated that they were not the Responsible Entity for any 11m+ residential buildings.

As at 31 August 2024, 2,507 social buildings 11 metres and over in height have been identified as having life-critical fire-safety cladding defects. Of the 2,507 buildings identified with unsafe cladding:

• 1,888 were reported by Registered Providers to have unsafe cladding at the time of their most recent assessment. This could include buildings whose remediation work has been completed but await building control sign off and those awaiting a subsequent assessment to confirm no outstanding life-critical fire-safety defects. Additional information on these buildings is available in the accompanying management information tables, social housing provider release document and the Regulator for Social Housing’s publication on Fire safety remediation in social housing in England.
• 513 were reported by Registered Providers to have unsafe cladding since 14 June 2017 but prior to the most recent assessment, which have since been remediated. Of these, 20 were reported by Registered Providers to have unsafe cladding in the previous survey (as at 31 March 2024) but have since completed remediation.
• 106 were identified under other remediation programmes (BSF, ACM, CSS or developer remediation) as having unsafe cladding and are also being monitored in those programmes.

Of the 2,507 buildings identified to have unsafe cladding:

• 703 buildings (28%) are reported to have completed remediation – an increase of 40 since reported in the July data release. Of these 703, 641 (26% of all buildings) have received building control sign-off.
• 1,268 buildings (51%) are reported to have started or completed remediation – an increase of 60 since reported in the July data release.
• 699 buildings (28%) are reported to have not started remediation but have plans in place - a decrease of 18 since reported in the July data release.

Although information from registered providers of social housing is received quarterly, these statistics will be updated monthly as information from other programmes which relate to social building remediation is updated monthly.

Height breakdown

Figure 20: 59% of the 18m+ social buildings identified to have unsafe cladding have started or completed remediation, compared to 42% of the 11-18m buildings.

Additional information available for individual social housing providers is available in the accompanying management information tables and social housing provider release document.

The estimates in this section exclude three buildings identified with unsafe cladding which have been decanted prior to demolition.

Social Housing remediation: recent assessments

The estimates in this section include buildings self-reported by registered providers in the latest survey (as at 30 June 2024) as having unsafe cladding at the time of their most recent assessment.

Registered Providers reported that 1,888 buildings have been identified with unsafe cladding at the time of the most recent assessment. Of these:

• 108 buildings (6%) are reported to have completed remediation – an increase of five since reported in the July data release. Of these 108, 50 buildings (3% of all buildings) have received building control sign-off.
• 670 buildings (35%) are reported to have started or completed remediation - an increase of 39 since reported in the July data release.
• 674 buildings (36%) are reported to have not started remediation but have plans in place - a decrease of 26 since reported in the July data release.

Enforcement

Information in this section is correct as of 23rd August 2024 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 of 23rd August 2024, enforcement action has been, or is being, taken under the Housing Act against:

• 430 buildings over 11m with unsafe cladding - an increase of 12 since the end of July
• including 131 buildings with Joint Inspection Team support – an increase of 3 since the end of June

Of the 430 buildings where a local authority had undertaken an inspection, we are aware that:

• 106 had a Category 1 HHSRS rating
• 280 buildings had a Category 2 HHSRS 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 430 buildings, we are aware that at least 137 improvement notices, 36 hazard awareness notices and 1 prohibition order have been served to date. We understand that 35 of the improvement notices have been subject to appeals.
