The Ministry of Housing, Communities and Local Government has published the 106th monthly building safety remediation data release. It applies to England.
As at the end of August 2026, 4,724 residential buildings of 11 metres and over were identified with unsafe cladding and monitored, 27 more than at the end of July. Of these, 1,849 (39%) have completed remediation works, 722 (15%) have started and 2,153 (46%) have not started. The department estimates that a further 1,100 to 2,600 buildings expected to be remediated are yet to be confirmed as eligible for a programme.
By programme:
- ACM (Grenfell-style cladding): of 516 high-rise buildings, 503 (97%) have started or completed works and 478 (93%) have completed. Thirteen have yet to start; two are vacant, and one has had local authority enforcement action.
- Building Safety Fund: of 640 high-rise buildings, 564 (88%) have started or completed works on non-ACM cladding, and 490 (77%) have completed.
- Cladding Safety Scheme: 1,497 buildings are eligible. Of these, 417 (28%) have started or completed works and 139 (9%) have completed. A further 2,660 are in the pre-eligible stages.
- Developer remediation: 2,679 buildings have life-critical fire safety defects that developers have committed to remediate or pay to remediate. Developers reported, as at 31 July 2026, that 1,416 (53%) have started or completed works.
- Social self-funded: 708 buildings, of which 518 (73%) are reported to have started or completed works. Both figures fell from July. The release says fluctuations are expected while data is migrated to the National Remediation Database, and links changes to continued data cleansing by registered providers and a methodological change in computing remediation stages.
Local authorities have taken or are taking enforcement action under the Housing Act 2004 against 929 buildings over 11 metres with suspected unsafe cladding, six more than in July.
Figures from December 2025 are not directly comparable with earlier months because of a change in how social sector buildings are collected and categorised. Progress also differs by height: 62% of 18m+ buildings have started or completed works, against 46% of 11-18m buildings.
Government estimates, as at March 2026, that 5,900 to 7,400 residential buildings of 11 metres and over have or had unsafe cladding. The estimated cost of remediation, as at March 2025, is £11.8bn to £22.7bn.
The next release is due at 9.30am on 28 October 2026.
What this means for people living in or owning affected buildings
The figures are national totals for each remediation programme. Programmes differ in how far work has progressed, and the release notes that this reflects their differing maturity. The release also estimates about 250,000 dwellings are in monitored occupied private and social sector buildings with unsafe cladding, of which about 111,000 are in buildings that have completed remediation and about 36,000 more are in buildings where work has started.
