According to the Fire Protection Association, the Ministry of Housing, Communities and Local Government (MHCLG) has published updated figures on the remediation of high-rise residential buildings with unsafe cladding in England.

As of the end of March 2025, 5,031 residential buildings 11 metres and over in height have been identified as having unsafe cladding.

MHCLG reported that remediation work has either started or been completed on 2,459 of these buildings, with 1,637 having completed the process.

Progress reported across safety funding schemes

The Fire Protection Association reported that 824 buildings have been confirmed as eligible for support through the Building Safety Fund.

Of the remaining 2,861 registered for the scheme, 456 have been transferred to developers and 121 to the Cladding Safety Scheme.

There are now 617 buildings eligible under the Cladding Safety Scheme, and 602 of these have signed Grant Funding Agreements.

This represents an increase of 37 signed agreements since the previous reporting period in February 2025.

Developer remediation and social housing data

MHCLG confirmed that 4,648 buildings are within scope of the developer remediation contract.

Of these, 844 buildings have been identified with life-critical fire safety defects which developers are responsible for addressing.

The Regulator of Social Housing has reported that 2,718 social housing buildings 11 metres or taller have been identified with cladding-related fire safety defects.

Of these, 857 buildings have completed remediation works.

A total of 1,915 of the affected social buildings were reported by registered providers during their most recent assessment.
