The government's April 2026 remediation data shows 2,415 of 4,378 monitored residential buildings of 11 metres and over in England have started or completed cladding remediation, with 1,544 completed.
Key facts
- Who: Residential buildings of 11 metres and over in England with unsafe cladding, and those connected to the government's remediation programmes
- From: Data current at 30 April 2026; published 27 May 2026
- Source: Building Safety Remediation: monthly data release – April 2026
The Ministry of Housing, Communities and Local Government (MHCLG) published its 102nd monthly building safety remediation data release on 27 May 2026. It applies to England.
Overall progress
At the end of April 2026, 4,378 residential buildings of 11 metres and over with unsafe cladding were being monitored, 56 more than at the end of March. Of these, 2,415 (55%) have started or completed remediation and 1,544 (35%) have completed it. A further 871 (20%) have started work and 1,963 (45%) have not started.
MHCLG estimates the monitored buildings are 60-75% of those expected to be remediated in its programmes. The March release gave 50-76%; the change reflects updated estimates of how many buildings have unsafe cladding.
Those estimates, as of March 2026, are 5,900 to 7,400 residential buildings of 11 metres and over in England that have or had unsafe cladding requiring work. An estimated 238,000 dwellings are in the monitored occupied private and social sector buildings.
By programme
- ACM programme: Of 516 high-rise buildings with "Grenfell-style" ACM cladding, 500 (97%) have started or completed work and 467 (91%) have completed it. Sixteen have not started: two are vacant, 11 occupied buildings have forecast start dates, two have had local authority enforcement action and one came into scope in 2026.
- Building Safety Fund: Of 678 high-rise buildings, 557 (82%) have started or completed work on non-ACM cladding, and 470 (69%) have completed it.
- Cladding Safety Scheme: 1,239 buildings are eligible; 363 (29%) have started or completed work and 100 (8%) have completed it. A further 2,388 are at pre-eligible stages.
- Developer remediation: 2,553 buildings have life-critical fire safety defects that developers have committed to remediate or pay to remediate. Developers report 1,181 (46%) started or completed. Developer data was received as at 31 January 2026.
- Social self-funded: 570 buildings, of which 384 (67%) have started or completed work. Figures are expected to fluctuate while records move to the National Remediation System.
Enforcement
As at 24 April 2026, local authority enforcement action had been, or was being, taken under the Housing Act 2004 against 880 buildings over 11 metres with suspected unsafe cladding, 17 more than at the end of March.
Costs
The cost estimates are unchanged from March 2025: £11.8bn to £22.7bn to remediate residential buildings containing dwellings. Under current plans, MHCLG will have £9.2bn available to fund remediation of external wall system defects, made up of a £5.2bn Exchequer contribution, an estimated £0.7bn in refunds from developers and a £3.4bn Building Safety Levy revenue target. The release says the Levy target will be reviewed and adjusted as cost estimates are updated.
What this means for people in affected buildings
The figures are national totals and do not show what will happen in any one building. Progress differs by programme, height and tenure: 62% of monitored buildings of 18 metres and over have started or completed remediation, compared with 47% of those of 11-18 metres.
The release notes that forecast start dates for ACM buildings are based on information from building owners and agents and may change. The next release is due at 9.30am on 24 June 2026.
