Overall remediation

As at the end of September 2024, there are 4,821 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 50 since the end of August 2024. 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 3,457 buildings with unsafe cladding since the end of September 2023.

Overall, 2,412 buildings (50%) have either started or completed remediation works. Of these, 1,412 buildings (29%) have completed remediation works.

Figure 1: Of the 4,821 buildings identified with unsafe cladding, 2,412 (50%) have started or completed remediation works, of which 1,412 (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 September 2024) since previous publication

As at 30 September 2024 of the 513 high-rise (18 metres and over in height) residential and publicly owned buildings with ACM cladding systems, unlikely to meet Building Regulations, 490 (96%) have either started or completed remediation works, no change since the end of August.

Of these, 443 buildings (86%) have completed ACM remediation, including those awaiting building control sign-off, an increase of one since the end of August.

There are 23 buildings yet to start ACM remediation (4% of all buildings), an increase of 10 since the end of August. One building is vacant so does not pose a risk to resident safety, eight occupied buildings have forecast start dates, six further buildings have had local authority enforcement action taken against them, and the remaining eight buildings have come into scope in recent months.

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

As at 30 September 2024, of the 809 high-rise (18 metres and over in height) residential buildings proceeding with an application for funding through the Building Safety Fund, 176 buildings (22%) have started remediation works and 341 buildings (42%) 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, no change since the end of August. Of these, 341 buildings (42% of buildings) have completed remediation works, an increase of 15 since the end of August.

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

As at 30 September 2024, 432 buildings 11 metres and over in height have been assessed as eligible for the Cladding Safety Scheme (including 108 buildings that have transferred from the BSF), an increase of 27 since the end of August. All have either signed grant funding agreements or are in the process of doing so and are actively procuring works in the market. 22 buildings have started remediation work on site, an increase of 12 since the end of August.

The CSS continues to investigate and pull in potentially eligible buildings. There are a further 1,381 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, 367 buildings are progressing through eligibility checks, and 1,014 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 30 September 2024

As at 30 September 2024, 1,629 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 3 since reported in the August data release.

Of these, developers reported that 772 (47%) have either started or completed remediation works, an increase of 3 since reported in the August data release. Of these, 413 (25% of buildings) are reported to have completed remediation works, an increase of 3 since reported in the August data release.

When excluding buildings reported with only non-cladding defects, there are 1,452 buildings which developers have reported as having unsafe cladding, of which 718 (49%) are reported to have started or completed remediation, including 384 (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 30 September 2024

As at 30 September 2024, 2,536 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, 1,295 (51%) have started or completed remediation works, an increase of 27 since reported in the August data release. Of these, 704 (28% of buildings) have completed remediation, an increase of one since reported in the August data release.

Enforcement – monthly update (as at 19 September 2024) since previous publication

As at 19 September 2024, local authority enforcement action has been, or is being, taken under the Housing Act 2004 against 444 buildings over 11m with unsafe cladding, an increase of 14 since the end of August.

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

Figure 2: 2,412 residential buildings (50% of identified buildings) have started or completed remediation on unsafe cladding, of which 1,412 (29% of identified buildings) have completed remediation works.

Overall remediation: key statistics

Of the 4,821 residential buildings 11 metres and over in height with unsafe cladding the department is monitoring, as at 30 September 2024:

• 1,412 buildings (29%) have completed remediation, including those awaiting building control sign off
• 1,000 buildings (21%) have started remediation
• 2,409 buildings (50%) have not started remediation

Since the end of August 2024:

• The department is monitoring the remediation progress of 50 more buildings.
• 35 more buildings are known to have started or completed remediation, and 20 more buildings are known to have completed remediation.

Since the end of September 2023:

• The department is monitoring the remediation progress of 3,457 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.
• 1,557 more buildings are known to have started or completed remediation, of which 868 more buildings are known to have completed remediation.

There are an estimated 260,000 dwellings in the occupied private and social sector 11m+ residential buildings with unsafe cladding that the department are monitoring. Of these an estimated 88,000 dwellings are in buildings that have completed remediation, and an estimated 56,000 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 30 September 2024, the department has identified 513 high-rise residential and publicly owned buildings identified with ACM cladding systems unlikely to meet Building Regulations, an increase of 10 since the end of August.

• 443 buildings (86% of all buildings) have completed ACM remediation – an increase of one since the end of August. Of these, 415 buildings (81% of all buildings) have received building control sign off – an increase of three since the end of August.
• 490 buildings (96% of all buildings) have started or completed ACM remediation – no change since the end of August. Of these, 473 buildings (92% of all buildings) have removed ACM cladding – no change since the end of August.

There are an estimated 26,400 – 29,700 dwellings in private and social sector buildings that have completed remediation, and a further 5,400 – 5,500 dwellings in occupied private and social sector buildings that have yet to be remediated.

Driving ACM remediation forward

There are 23 buildings yet to start ACM remediation (4% of all buildings) – an increase of 10 since the end of August. One building is vacant so does not pose a risk to resident safety.

The 10 buildings determined as in scope of the ACM monitoring programme this month are eligible for funding from the BSF. The Department continues to work closely with the applicant and is currently expediting the review of FRAEWs for these buildings.

Table 3: Enforcement action and forecast start dates for occupied high-rise buildings yet to start ACM remediation, 30 September 2024

Of the 22 high-rise occupied buildings yet to start ACM remediation:

• Eight buildings are forecast to start works in 2025 and five of these have had local authority enforcement action taken against them.
• Six further buildings without a forecast start date have had local authority enforcement action taken against them.
• The remaining eight buildings have been determined as in scope of the ACM monitoring programme in recent months, and the department continues to engage with building owners to ensure their 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.

BSF remediation: key statistics

As at 30 September 2024, 809 buildings were assessed as eligible and are proceeding with an application for funding from the Building Safety Fund. The remaining 2,851 buildings registered with the fund are either ineligible (1,111), withdrawn (1,595), in review or have given insufficient evidence (21), or have transferred to the Cladding Safety Scheme (124).

Of the 2,851 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 30 September, 124 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 809 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 809 buildings proceeding with an application for funding, 138 buildings have been assessed with a Fire Risk Appraisal for External Walls (FRAEW), and 671 have been assessed under the BSF 2020 CAN criteria. Further details are available in the technical note.

Of the 809 buildings proceeding with an application for funding, 517 buildings (64%) have either started or completed remediation works – no change since the end of August.

Of the 517 buildings that have started or completed remediation as at 30 September 2024:

• 176 buildings (22% of all buildings) have started remediation.
• 341 buildings (42% of all buildings) have completed remediation – an increase of 15 since the end of August. Of these, 217 buildings (27% of all buildings) have received building control sign off.

There are 292 eligible buildings proceeding with an application for funding that have not started remediation, of which:

• 136 (17% of all buildings) have remediation plans in place
• 156 (19% 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: 74 more buildings proceeding with an application for funding in the BSF have started or completed remediation since the end of September 2023

Since the end of September 2023:

• 159 fewer eligible buildings are proceeding with an application for funding from the Building Safety Fund.
• 74 more eligible buildings have started or completed remediation, and 156 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 63% 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 30 September 2024 and shows a monthly update from the previous publication.

Figure 14: There are 1,813 buildings at different stages of the Cladding Safety Scheme, including 367 buildings with live applications and 432 eligible buildings, of which 22 buildings have started works.

Table 6: Remediation status for buildings within the Cladding Safety Scheme, 30 September 2024

Cladding Safety Scheme: Key statistics

As at the end of September 2024, there were 1,813 buildings in the different stages of the Cladding Safety Scheme (432 eligible buildings and 1,381 pre-eligible buildings). Of the 1,381 pre-eligible buildings:

• 1,014 buildings are in the pre-application stage.
• 367 buildings have a live application and are progressing through the eligibility stages.

There are 432 eligible buildings as at the end of September 2024, an increase of 27 since the end of August. 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 432 eligible buildings:

• 382 buildings (88% of eligible buildings) have signed Grant Funding Agreements (GFA) - an increase of 39 since the end of August
• Of these, 253 buildings (59% of all eligible buildings) have received a pre-tender support payment – an increase of 26 since the end of August
• 22 buildings have started remediation works on site – an increase of 12 since the end of August.

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

Four eligible buildings and one building with a live application are in Northern Ireland, with the remainder in England.

Height breakdown

Tenure breakdown

Figure 16: Of the 432 eligible buildings in the CSS, 339 are private sector buildings and 93 are social sector buildings.

Developer-Led Remediation

Information in this section received by developers is correct as at 31 July 2024 and remains unchanged 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 30 September 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.

Developer remediation: key statistics

As at 30 September 2024, 55 developers have signed the developer remediation contract, although data for only 54 developers is included in this data release due to one developer who has gone into administration. Between them, there are 4,668 buildings covered by the developer remediation contract. Of which, there are 1,629 buildings identified as having life-critical fire safety risks that will be remediated by developers. This is an increase of 3 compared to the 31 August 2024 Building Safety Data Release, due to a correction in the analysis used to identify buildings with defects.

Of the 1,629 buildings identified as having life-critical fire safety risks:

• 413 (25%) are reported to have completed remediation– an increase of 3 since reported in the August data release. Of the 413 buildings that are reported to have completed remediation, 342 buildings (21% of all buildings) are reported to have received building control sign-off.
• 772 (47%) are reported to have started or completed remediation – an increase of 3 since reported in the August data release.
• 455 (28%) are reported to have not started remediation but have plans in place – no change since the August 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 1,629 buildings identified as requiring remediation have an estimated cost of remediation of around £3.3 billion. This has not changed compared to the August data release, but 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 1,629 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 - no change since the August data release. Of these 39, 25 buildings (6% of all buildings) are reported to have received building control sign-off.
• 141 (32%) have started or completed remediation - no change since the August data release.
• 133 (30%) are reported to have not started remediation but have plans in place - no change since the August 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 1,452 buildings which developers have reported as having unsafe cladding. Of these:

• 384 (26%) are reported to have completed remediation - an increase of 3 since reported in the August data release. Of these 384, 320 buildings (22% of all buildings) are reported to have received building control sign-off.
• 718 (49%) are reported to have started or completed remediation - an increase of 3 since reported in the August data release.
• 418 (29%) are reported to have not started remediation but have plans in place - no change since the August 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 – no change since the August data release. Of these, 194 buildings (14% of all buildings) are reported to have received building control sign-off.
• 553 buildings (41%) have started or completed remediation – no change since the August data release.
• 429 buildings (32%) have not started remediation but have a plan in place – an increase of 82 since reported in the August data release - no change since the August 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 30 September 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	642	25%	642	25%
Remediation complete – awaiting building control sign-off	62	2%	704	28%
Remediation started	591	23%	1295	51%
Remediation works planned	701	28%	1996	79%
Remediation plans unclear from survey	540	21%	2536	100%
Total	2536	100%	2536	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 30 September 2024, 2,536 social buildings 11 metres and over in height have been identified as having life-critical fire-safety cladding defects. Of the 2,536 buildings identified with unsafe cladding:

• 1,914 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.
• 109 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 2,536 buildings identified to have unsafe cladding:

• 704 buildings (28%) are reported to have completed remediation – an increase of one since reported in the August data release. Of these 704, 642 (25% of all buildings) are reported to have received building control sign-off.
• 1,295 buildings (51%) are reported to have started or completed remediation – an increase of 27 since reported in the August data release.
• 701 buildings (28%) are reported to have not started remediation but have plans in place – an increase of two since reported in the August 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. The figures in the September data release include revisions to the end of June data provided by one social housing provider.

Height breakdown

Figure 20: 60% 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 1,914 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 – no change since the August data release Of these 108, 50 buildings (3% of all buildings) are reported to have received building control sign-off.
• 696 buildings (36%) are reported to have started or completed remediation - an increase of 26 since reported in the August data release. This increase is due to one social housing provider providing revised end of June figures following the August data release.
• 674 buildings (35%) are reported to have not started remediation but have plans in place – no change since the August data release

Enforcement

Information in this section is correct as of 19th September 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 19th September 2024, enforcement action has been, or is being, taken under the Housing Act against:

• 444 buildings over 11m with unsafe cladding - an increase of 14 since the end of August
• including 140 buildings with Joint Inspection Team support – an increase of 9 since the end of August

Of the 444 buildings where a local authority had undertaken an inspection, we are aware that:

• 109 had a Category 1 HHSRS rating
• 288 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 444 buildings, we are aware that at least 140 improvement notices, 37 hazard awareness notices and 1 prohibition order have been served to date. We understand that 36 of the improvement notices have been subject to appeals.
