Social housing remediation data release: 30 June 2025

Published 25 September 2025

Applies to England

Headline findings

• As at 30 June 2025, registered providers social housing reported that they were responsible for 17,140 11m+ buildings. 
• Registered providers of social housing reported 2,810 11m+ buildings with life-critical fire safety defects related to the external wall system (16% of all 11m+ buildings). Two providers – London Borough of Brent and Bright and Hove City Council – reported they were unable to provide information on their number of 11m+ buildings with life-critical fire safety defects related to the external wall system. 
• Of them, registered providers reported that 1,307 buildings have started or completed remediation (47% of 11m+ buildings with life-critical fire safety defects related to the external wall system). 

About the Fire Safety Remediation Survey 

Data was collected from Registered Providers of social housing (RPs) via the Fire Safety Remediation Survey (the survey) for their 11m+ residential building stock in England. The survey required landlords to provide aggregate level information to Regulator of Social Housing (RSH) for all 11m+ residential buildings where they are the Responsible Entity, and landlords were asked to submit fire safety remediation data at a building level for assessment by Ministry of Housing, Communities and Local Government (MHCLG). Local Authority Registered Providers (LARPs) were asked to complete the survey on a voluntary basis. The survey reflects data as at 30 June 2025. 

549 registered providers of social housing were invited to respond to this round of the survey on their 11m+ stock. 939 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. 540 registered providers responded to this round of the survey. Of them, 112 registered providers reported that they were not responsible for any 11m+ residential buildings, and 430 registered providers reported that they were responsible for at least one 11m+ residential building.   

Of the 430 registered providers, two registered providers (London Borough of Brent and Brighton and Hove City Council) reported they were not able to confidently provide further information on their 11m+ buildings as of 30 June 2025 while they were undertaking a review of their data. As a result, this data release includes only their total number of 11m+ buildings, which they confirmed is correct as at 30 June 2025. No information is included for the assessment status, presence of life-critical fire safety defects related to the external wall system or remediation status of their buildings as at 30 June 2025. MHCLG and RSH are working with these two providers to support their reviews and future data submission. 

This data release covers responses to the building-level questionnaire. The estimates in this data release may differ from those included in the Fire safety remediation in social housing in England data release, which is published by the Regulator for Social Housing and uses aggregate-level data rather than building-level data. This is due to discrepancies between the aggregate-level return and building-level return for a small number of registered providers. 

Of 549 registered providers that were invited to respond to this round of the survey, 430 providers reported that they were responsible for at least one building that is 11m+. This release is based on the building-level data returns from these 428 providers, as at 30 June 2025 and two providers (London Borough of Brent and Brighton and Hove City Council) which confirmed their total number of 11+m buildings as at 30 June 2025 but which reported they were not able to confidently provide further information on their 11m+ buildings. 

These 430 providers reported that they were responsible for a total of 17,140 residential buildings above 11 metres in height which contain at least one unit of social housing. Of those 430 providers: 

• 197 providers reported responsibility for more than five 11m+ buildings, including two providers (London Borough of Brent and Brighton and Hove City Council) which reported they were not able to confidently provide information on their assessment status, presence of life-critical fire safety defects, or remediation status. Further information on these providers’ buildings is provided available in the accompanying management information tables. 
• 233 providers reported responsibility for five or fewer 11m+ buildings each. The data for these 233 providers is grouped into a single “Other RPs” row in the accompanying management information tables.  The data for these providers is grouped in this way to avoid inadvertently identifying individual buildings with life-critical fire safety defects. 

Overview 

This data release is split into four sections: 

1. Progress with building works assessments and specialist assessments. This section shows the number of buildings in England over 11 metres which contain at least one unit of social housing, for which social housing providers who responded to the survey are the responsible entity. This section also also sets out the number and proportion of buildings that have had a recent building works assessment and/or a specialist assessment (such as a Fire Risk Appraisal of External Wall System, FRAEW). A breakdown by provider is available in the accompanying management information tables. 
2. Buildings with EWS defects. This section sets out the number and proportion of buildings that were found to require remedial works to mitigate life-critical fire safety defects related to the external wall system (EWS), since June 2017 and at the time of the most recent building works assessment. A breakdown by provider is available in the accompanying management information tables. 
3. Progress with remediation. This section shows the number and proportion of buildings requiring remedial works to mitigate life-critical fire safety defects related to the EWS. This section sets out the number and proportion of buildings with EWS defects, where remediation has been completed, has started, works are planned or plans are unclear. A breakdown by provider is available in the accompanying management information tables. 

1. Progress with assessments 

As of 30 June 2025, social housing providers reported that: 

• 16,978 of the 17,140 buildings for which they are responsible (99%) have had a recent building works assessment.*
• 17 buildings (<1%) have not had a recent building works assessment. 

Recent building works assessment?	Number	Percentage	Cumulative Number	Cumulative Percentage
Yes	16,978	99%	16,978	99%
No	17	<1%	16,995	99%

London Borough of Brent and Brighton and Hove City Council’s figures are included in the total number of 11m+ buildings to calculate the percentage of 11+m buildings which have had or have not had a recent building works assessments.  

2. Buildings with life-critical fire safety EWS defects 

Providers reported that 2,810 buildings (16% of 11m+ buildings) have been found to have LCFS related to the EWS since June 2017. Of 2,810 buildings with life-critical fire safety defects related to the EWS: 

• 1,925 buildings had LCFS relating to the EWS (11% of 11m+ buildings) at the time of their most recent building works assessment. 
• 885 buildings were identified as having life-critical fire safety defects relating to the EWS which were remediated prior to their most recent building works assessment (5% of 11m+ buildings). 

*A building works assessment should comply with the requirements of the Fire Safety Order, for example a building works assessment or Fire Risk Appraisal of External Walls (FRAEW). 

This excludes 1 building identified with EWS defects which was decanted prior to demolition. 

London Borough of Brent and Brighton and Hove City Council’s figures are included in the total number of 11m+ buildings to the percentage of 11+m buildings which have been assessed and identified life-critical fire safety defects related to the EWS since June 2017 or in their most recent building works assessment. 

3. Progress with remediation 

2,810 buildings (16% of 11m+ buildings) that were identified as having life-critical fire safety defects relating to the External Wall System (EWS) since June 2017. Of them: 

• 1,042 buildings (37%) completed remediation works. Of them, 885 buildings completed remediation works since June 2017 but prior to their most recent building works assessment, and 157 completed remediation prior to their most recent building works assessment.**
• 265 buildings (9%) have started remediation works.
• 980 buildings (35%) have not started remediation works but have plans in place. 
• 523 buildings (19%) have not started remediation works and were reported to have no or unclear plans in place.*** 

**which could include buildings whose remediation work has been completed but is awaiting building control sign-off and those awaiting a post-works building works assessment to check whether any life-critical fire safety defects remain. 

***This is either because works have not started and there are no plans in place, or the remediation status has been left blank in the survey. 

Remediation status of buildings with EWS defects	Number	Percentage	Cumulative Number	Cumulative Percentage
Works Complete - Prior to Recent Assessment	885	31%	885	31%
Works Complete - Since to Recent Assessment	157	6%	1,042	37%
Works Started	265	9%	1,307	47%
Works Not Started - Plans in Place	980	35%	2,287	81%
Works Not Started - No or Unclear Plans	523	19%	2,810	100%
