The latest building safety remediation data has been published by the Ministry of Housing, Communities, and Local Government (MHCLG), with more than 5,200 buildings with unsafe cladding having now been identified
Data recorded for the end of July 2025 reveals that 2,502 (48%) buildings have either started or completed remediation works, with 1,780 (34%) buildings having had all work completed. 3,434 buildings are still awaiting completion of remediation, while 52% or 2,712 buildings have not yet started remedial work.
In total, 5,214 residential buildings 11 metres and over in height have been identified as having unsafe cladding, which is an increase of 24 since the end of June 2025. These are the buildings covered by the government’s ongoing ACM programme, Building Safety Fund, Cladding Safety Scheme, developer remediation contract, and as reported by registered providers of social housing.
“This is an estimated 61-91% of all buildings 11 metres and over in height expected to be remediated as part of MHCLG’s remediation programmes,” the report highlights.
MHCLG estimates that there are between 5,900 and 9,000 residential buildings 11 metres or higher that have or had unsafe cladding requiring work in England, equating to 12-13% of the residential building stock in England for buildings that are 11 metres and more in height. MHCLG expects that between 5,700 and 8,600 residential buildings “will be or have been remediated or mitigated” as part of its five remediation schemes.
For those buildings covered by the developer-led remediation programme, 2,026 buildings have life-critical fire safety risks. Currently, only 25% or 516 buildings have had remediation work completed, showing no change since the data release from June. A reported 21% or 430 buildings have received building control sign-off, and around 372 or 18% of buildings have not started remediation but have plans in place, while 657 or 32% of buildings have not started work and do not have any plans in place.
Key statistics for social housing remediation indicate there are 2,805 buildings with unsafe cladding. Of these, 34% or 953 buildings have completed remediation, with 905 buildings having received building control sign-off. Additionally, 1,578 buildings (56%) have not yet started remediation, and 997 buildings (36% of all buildings with defects) have not started remediation but have plans in place.
MHCLG reports: “Of the 1,578 buildings with cladding defects that have not yet started remediation, 1,222 buildings are not currently covered by the developer remediation contract or are not currently in another government programme.”
For all buildings being monitored by the department, the highest concentration appears to be around urbanised areas in England, such as Greater London, Greater Manchester, West Yorkshire, and the south coast.
MHCLG has also shared enforcement action taken by local authorities in relation to buildings over 11 metres in height with suspected unsafe cladding. An increase of 93 since the end of June, the department reports 659 buildings have seen enforcement action. Of this figure, 215 improvement notices, 70 hazard awareness notices, and one prohibition order were issued. Around 52 of the improvement notices have been subject to appeals.
