Building Safety Remediation: monthly data release - February 2024

Updated 26 March 2024

Applies to England

Date of next publication: 9.30am on Thursday 18 April 2024

Since October 2023, 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.

1. Headlines

Overall remediation

As at the end of February 2024, there are 4,092 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 120 since the end of January 2024.

At the beginning of 2023, DLUHC 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, DLUHC started monitoring the remediation progress of buildings in the Cladding Safety Scheme, developer remediation contract and reported by registered providers of social housing. This change in scope has largely driven the reporting of an additional 2,475 buildings with unsafe cladding since the end of February 2023.

Overall, 1,815 buildings (44%) have either started or completed remediation works. Of these, 863 buildings (21%) have completed remediation works. The total number of buildings reported to have started or completed remediation works has more than doubled since the end of February 2023.

Figure 1: Of the 4,092 buildings identified with unsafe cladding, 1,815 (44%) have started or completed remediation works, of which 863 (21%) 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 due to buildings transferring from the BSF to being remediated by developers. 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 decrease in the total number of reported buildings between June and September 2023 was 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.

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

As at 29 February 2024, of the 496 high-rise (18 metres and over in height) residential and publicly owned buildings with ACM cladding systems, unlikely to meet Building Regulations, 485 (98%) have either started or completed remediation works, an increase of five since the end of January.

Of these, 433 buildings (87%) have completed ACM remediation, including those awaiting building control sign-off, an increase of three since the end of January.

There are 11 buildings yet to start ACM remediation (2% of all buildings), a decrease of five since the end of January. One building is vacant so does not pose a risk to resident safety, eight occupied buildings have forecast start dates and the other two without a start forecast have had local authority enforcement action taken against them.

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

As at 29 February 2024, of the 938 high-rise (18 metres and over in height) residential buildings proceeding with an application for funding through the Building Safety Fund, 237 buildings (25%) have started remediation works and 261 buildings (28%) have completed remediation on unsafe non-ACM cladding, including those awaiting building control sign-off.

Overall, 498 high-rise buildings (53%) in the BSF have either started or completed remediation works on non-ACM cladding, an increase of 2 since the end of January. Of these, 261 buildings (28% of buildings) have completed remediation works, an increase of 11 since the end of January.

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

As at 29 February 2024, 424 buildings 11 metres and over in height have live applications with the Cladding Safety Scheme, which launched fully in July 2023, and are progressing through the eligibility checks.

A further 152 buildings have already been assessed as eligible for the programme, an increase of 25 since the end of January. All have either signed grant funding agreements or are in the process of doing so, 100 applications are at the stage of assembling a works package and one application has started work.

This is in addition to over 3,100 buildings in the pipeline that are being investigated, and where within programme parameters, are being brought into the application process, including 447 buildings in the pre-application stage.

Developer remediation – quarterly update (as at end January 2024) since previous publication

As at 31 January 2024, 1,500 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, an increase of 155 since October 2023.

Of these, developers reported that 624 (42%) have either started or completed remediation works, an increase of 151 since the end of October 2023. Of these, 307 (20% of buildings) are reported to have completed remediation works, an increase of 45 since the end of October.

When excluding buildings reported with only non-cladding defects, there are 1,403 buildings which developers have reported as having unsafe cladding, of which 587 (42%) are reported to have started or completed remediation, including 284 (20% of buildings) which are reported to have completed remediation.

Social housing sector – data remains at end November 2023 (the same as previous publication)

As at 30 November 2023, a survey of Registered Providers of social housing identified 1,952 buildings 11 metres and over in height as having unsafe cladding, an increase of 344 compared to the end of August 2023.

Of these, providers have reported that 729 (37%) have either started or completed remediation works (an increase of 229 since the end of August), including 204 buildings (10%) reported to have completed remediation (an increase of 98 since the end of August 2023).

Enforcement – monthly update (as at end February 2024) since previous publication

As at 29 February 2024, local authority enforcement action has been, or is being, taken under the Housing Act 2004 against 359 high-rise buildings with unsafe cladding.

2. Introduction

This data release provides data on:

• Remediation progress across DLUHC’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 DLUHC’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.

4. Building safety overview

The government has made ground-breaking reforms to building and fire safety legislation and is making good progress in dealing with the legacy of unsafe cladding in England to make homes safe. All residential buildings above 11 metres in England have a pathway to fix unsafe cladding, either through a taxpayer-funded scheme or through a developer-funded scheme, protecting leaseholders from these costs. 

Building owners and the industry that constructed and profited from the defective buildings have a responsibility to make sure these buildings are safe. 55 developers have taken responsibility for fixing life-critical fire safety defects arising from design or construction by signing the developer remediation contract. Of these, 53 data reports have been submitted to DLUHC, which indicates developers are committed to fix or pay to fix residential buildings in England at an estimated cost to themselves of £3.0 billion. Data for one developer who signed the contract in January 2024 and data for a developer who has gone into administration are not included in this release. Data for the recent signatory will be added to future releases. The Responsible Actors Scheme has been established to monitor the progress made by responsible developers in identifying and remediating buildings. 45 developers have already joined the Scheme and any eligible developer who fails to comply with the terms of the developer remediation contract will be subject to significant prohibitions.

The government has committed £5.1 billion to address unsafe cladding on residential buildings where developers or building owners are not currently doing so. The government is prioritising the highest-risk buildings – high-rise buildings with unsafe, ‘Grenfell-style’ Aluminium Composite Material cladding – and has almost finished the ACM programme. Relevant high-rise residential buildings with other forms of unsafe cladding are remediated through the Building Safety Fund. After a pilot in autumn 2022, the full opening of the Cladding Safety Scheme in July 2023 marked the culmination of extensive work to ensure that medium-rise buildings have a pathway towards remediation. The Scheme is also open to new applications for 18m+ buildings outside of London. All eligible applications to the Building Safety Fund received before 9 May 2023 will continue through the Fund.

Registered providers of social housing are responsible for making sure their buildings are made safe in a proportionate and timely way. The Social Sector ACM Cladding Remediation Fund has funded the remediation of ACM cladding on social housing buildings. The BSF and CSS for 11m+ buildings with other forms of unsafe cladding is open to registered providers to provide funding equivalent to the amount which the registered provider would otherwise be entitled to pass on to leaseholders; or where remediation would render the owner financially unviable. A number of social housing buildings are also expected to be remediated by the original developers under the terms of developer remediation contracts.

This data release publishes data across all the above remediation activities to give an overview of the progress made to remediate unsafe cladding on residential buildings over 11m in England. Developers send the department regular updates on the progress of remediation on those buildings. This data release also includes data on how each developer is performing against their contractual commitments.

5. Overall remediation progress

Figure 2: 1,815 residential buildings have started or completed remediation on unsafe cladding, of which 863 (21%) have completed remediation works.

Overall remediation: key statistics

Of the 4,092 residential buildings 11 metres and over in height with unsafe cladding DLUHC are monitoring, as at 29 February 2024:

• 863 buildings (21%) have completed remediation, including those awaiting building control sign off
• 952 building (23%) have started remediation
• 2,277 buildings (56%) have not started remediation

Since the end of February 2023:

• DLUHC is monitoring the remediation progress of 2,475 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.
• 1,032 more buildings are known to have started or completed remediation, of which 402 more buildings are known to have completed remediation.

There are an estimated 238,000 dwellings in the occupied private and social sector 11m+ residential buildings with unsafe cladding that DLUHC are monitoring. Of these an estimated 59,000 dwellings are in buildings that have completed remediation, and an estimated 59,000 additional dwellings are in buildings that have started remediation.

Figure 3: Remediation progress differs across the programmes due to the differing maturity of the schemes.

Overall remediation by height

Figure 4: 53% of the 18m+ buildings DLUHC is monitoring the remediation progress of have started or completed remediation on unsafe cladding, compared to 30% of 11-18m buildings

Overall remediation by location

Figure 5: Most buildings that DLUHC are monitoring the cladding remediation of are concentrated around urbanised areas in England, particularly the urban areas of Greater London, Greater Manchester, West Yorkshire and the south coast

Local authorities with 10 or fewer 11m+ buildings monitored with unsafe cladding are excluded from this map as their inclusion could lead to the identification of buildings with unsafe cladding.

6. ACM remediation

Information in this section is correct as at 29 February 2024 and shows a monthly update from the previous publication.

Figure 6: 98% of the 496 identified ACM clad high-rise buildings have started or completed remediation, with 94% having had their ACM cladding removed and 87% having completed remediation.

Table 2: Remediation status of buildings with ACM cladding systems unlikely to meet Building Regulations, 29 February 2024

ACM remediation: key statistics

As at 29 February 2024, DLUHC has identified 496 high-rise residential and publicly owned buildings identified with ACM cladding systems unlikely to meet Building Regulations, no change since the end of January.

• 433 buildings (87% of all buildings) have completed ACM remediation – an increase of three since the end of January. Of these, 401 buildings (81% of all buildings) have received building control sign off – an increase of two since the end of January.
• 485 buildings (98% of all buildings) have started or completed ACM remediation – an increase of five since the end of January. Of these, 466 buildings (94% of all buildings) have removed ACM cladding - an increase of one since the end of January.

There are an estimated 26,000 – 29,300 dwellings in private and social sector buildings that have completed remediation, and a further 5,200 – 5,400 dwellings in occupied private and social sector buildings that have yet to be remediated.

Driving ACM remediation forward

There are 11 buildings yet to start ACM remediation (2% of all buildings) – a decrease of 5 since the end of January. One building is vacant so does not pose a risk to resident safety.

		Enforcement action	Enforcement action supported by Joint Inspection Team	Forecast start available	Forecast to start by the end of March 2024
Total	10	7	4	8	2

Table 3: Enforcement action and forecast start dates for occupied high-rise buildings yet to start ACM remediation, 29 February 2024

Of the 10 high-rise occupied buildings yet to start ACM remediation:

• Two buildings are forecast to start works by the end of March 2024.
• A further 6 buildings are forecast to start works by the end of December 2024.
• A further 2 buildings without a start forecast has had local authority enforcement action taken against them.

These forecast estimates are based on information provided by building owners and agents and are expected to 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 7: 98% of buildings are forecast to have started or completed ACM remediation works by the end of March 2024, with 95% estimated to be de-risked and 89% estimated to have completed remediation.

ACM remediation progress by year of identification

Figure 8: 99% of buildings identified at 31 December 2022 have started or completed remediation compared to 98% of all buildings in the programme.

Since 31 December 2021, 15 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, and nine in 2023.

Table 6: Remediation status for buildings within the Cladding Safety Scheme, 29 February 2024

Cladding Safety Scheme: Key statistics

As at the end of February 2024, there were 1,023 buildings in the different stages of the Cladding Safety Scheme. Of the 871 pre-eligible buildings:

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

There are 152 eligible buildings in programme as at the end of February 2024, an increase of 25 since the end of January 2024. Of the 152 eligible buildings:

• All 152 buildings have been issued or have signed Grant Funding Agreements (GFA) - an increase of 25 since the end of January - with those eligible receiving pre-tender support.
• 100 buildings are assembling or preparing to assemble a works package to complete the remediation works required, having signed a GFA – an increase of 31 since the end of January.
• One building has started remediation works on site – an increase of 1 since the end of January

In total, 128 buildings (84% of eligible buildings) have signed a Grant Funding Agreement and of these, 93 buildings (61% of eligible buildings) have received a pre-tender support payment.

There are over 2,600 further buildings being investigated to establish whether they can start the pre-application process.

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

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

Developer remediation: key statistics

As at 31 January 2024, there are 1500 buildings identified as having life-critical fire safety risks that will be remediated by developers, an increase of 155 since the end of October 2023. This increase is due to three new developers signing the developer remediation contract and pre-existing signatories identifying more buildings requiring works.  

Of the 1,500 buildings identified as having life-critical fire safety risks:

• 307 (20%) are reported to have completed remediation – an increase of 45 since the end of October.
• 624 (42%) are reported to have started or completed remediation – an increase of 151 since the end of October.
• 512 (34%) are reported to have not started remediation but have plans in place – an increase of 6 since the end of October.

The 1,500 buildings identified as requiring remediation have an estimated cost of remediation of around £3.0 billion.

There are an estimated 99,000 dwellings in buildings with defects that developers are committed to remediate. Of these, there are an estimated 40,000 dwellings in buildings that are reported as having either started or completed remediation works.

Based on start and completion dates reported by developers, 368 buildings are expected to start works and 252 buildings are expected to complete their remediation between 1 February 2024 and 31 January 2025.

Height breakdown

Figure 17: 46% of the 18m+ buildings have started or completed remediation, compared to 36% 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 1,403 buildings which developers have reported as having unsafe cladding. Of these:

• 284 (20%) are reported to have completed remediation
• 587 (42%) are reported to have started or completed remediation
• 481 (34%) are reported to have not started remediation but have plans in place.

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 1,324 buildings require remediation to life-critical fire safety risks and of those 1,205 buildings will be directly remediated by the developer, rather than remaining in the BSF or ACM fund to be remediated and then reimbursed by the developer. Some buildings are being remediated in the BSF or ACM but have other non-EWS life-critical fire safety defects which are also included in these statistics. Of these:

• 213 buildings (18%) have completed remediation
• 446 buildings (37%) have started or completed remediation
• 467 buildings (39%) have not started remediation but have a plan in place

Further information on the progress developers have made regarding the buildings they’ve reported on is available in the accompanying management information tables.

10. Social housing sector

Information in this section is correct as at 30 November 2023 and remains the same as the previous publication. 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 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’.

Social housing remediation: key statistics

Data was collected from 1,498 registered providers of social housing via a survey on their 11m+ stock. 96% of registered providers have responded.

As reported in the surveys submitted at aggregate level across the respondents, 1,952 buildings were reported to have unsafe cladding, an increase of 344 since the end of August 2023. This increase was mainly due to the improved response rate.

Of the 1,952 buildings reported to have unsafe cladding:
