As of the end of July 2025, 5,214 residential buildings over 11 metres in height with unsafe cladding are being monitored for remediation progress. This represents an increase of 24 buildings compared with June 2025 and accounts for an estimated 61–91% of all such buildings expected to be remediated under MHCLG’s programmes.

Since reporting began in October 2023 across all five remediation programmes, 1,417 more buildings have been added to the monitoring list.

Overall Progress

• 2,502 buildings (48%) have either started or completed remediation works.
• Of these, 1,780 buildings (34%) have fully completed remediation, including those awaiting building control sign-off.

This figure includes both high-rise (18m+) and mid-rise (11–18m) buildings.

Programme Updates

ACM Remediation

• Of 511 high-rise buildings with ACM cladding unlikely to meet Building Regulations, 497 (97%) have started or completed remediation, unchanged since June.
• 460 buildings (90%) have completed works, an increase of three.
• 14 buildings remain to start remediation. Nine have forecast start dates, one is vacant, one is under local authority enforcement, and three only came into scope during 2024–25.

Building Safety Fund (BSF)

• Of 774 high-rise buildings applying for BSF support, 545 (70%) have started or completed remediation, up by one since June.
• 424 buildings (55%) have completed works, up by six.
• 121 buildings (16%) have begun remediation but not yet completed.

Cladding Safety Scheme (CSS)

• 782 buildings have been deemed eligible for the scheme, an increase of 29.
• Of these, 142 buildings (18%) have started or completed works, up by 12.
• 49 buildings (6%) have completed remediation, up by six.
• A further 4,261 buildings remain in the pre-eligibility or pre-application stages.

Developer Remediation

• 2,026 buildings with life-critical fire safety defects have been identified for developer-led remediation, unchanged from June.
• 997 buildings (49%) have started or completed remediation.
• 516 buildings (25%) have completed works.
• When excluding non-cladding defects, 1,527 buildings have unsafe cladding, with 824 (54%) having started or completed remediation, and 448 (29%) completed.

Social Housing Sector

• 2,805 social housing buildings with life-critical cladding defects have been identified, an increase of nine.
• 1,227 buildings (44%) have started or completed remediation, up by one.
• 953 buildings (34%) have completed remediation, unchanged since June.

Enforcement

• Local authorities have taken or are pursuing enforcement action under the Housing Act 2004 against 659 buildings with unsafe cladding, an increase of 93 compared with June.

Estimated Building Stock Affected

MHCLG’s estimates (January 2025) indicate between 5,900 and 9,000 residential buildings over 11m with unsafe cladding, representing around 12–13% of England’s 11m+ residential stock.

• 11–18m buildings: 2,900–5,800 (7–10% of stock).
• 18m+ buildings: 2,900–3,200 (24–27% of stock).

Of the monitored 5,214 buildings as of 31 July 2025:

• 1,780 buildings (34%) have completed remediation.
• 722 buildings (14%) have started remediation.
• 2,712 buildings (52%) remain unremediated.

Impact on Dwellings

The department estimates 280,000 dwellings are within unsafe buildings being monitored.

• 105,000 dwellings are in remediated buildings.
• 47,000 dwellings are in buildings where works have started.
• 128,000 dwellings are in buildings yet to begin remediation.

Progress continues across the government’s five remediation programmes, with over a third of identified buildings now fully remediated. However, a significant proportion of residential buildings – representing hundreds of thousands of dwellings – remain in need of urgent works. Ongoing monitoring, enforcement, and support schemes remain crucial to accelerating remediation and ensuring resident safety.
