Cladding Remediation Update–May

Remediation continues to be a major focus for the Building Safety Regulator (BSR), with the latest Gateway Two data highlighting the increasing pressure on approval times for existing building safety works.

Current figures show that the median approval period for remediation applications has risen to 46 weeks, compared with 22 weeks for new-build applications, underlining the additional complexity involved in upgrading occupied Higher-Risk Buildings (HRBs). The King has also confirmed the introduction of a new bill requiring all landlords to remediate cladding on HRBs by the end of 2029 or face "unlimited fines or imprisonment".   

In response, remediation has been identified as a priority area within the BSR’s Strategic Plan for 2026/27, with a dedicated external remediation improvement plan introduced to help accelerate the application process. The measures outlined include the creation of a specialist external remediation multi-disciplinary team (MDT), designed to mirror the Innovation Unit already operating for new-build projects. The MDT will provide more coordinated technical oversight and clearer communication channels for applicants navigating the Gateway Two process. 

The regulator is also increasing its use of “Approval with Requirements”, allowing remediation projects demonstrating substantial compliance with Building Regulations to begin progressing while outstanding technical matters are resolved. The approach is intended to reduce delays without weakening safety standards, particularly where projects are urgently required to address life safety risks. 

The improvement plan also highlights recurring issues within remediation submissions that continue to contribute to delays. Common problems include insufficient evidence relating to the fire-resistance performance of replacement cladding systems and incomplete structural loading calculations demonstrating that existing buildings can safely support proposed remediation solutions. 

Alongside these operational changes, the Ministry of Housing, Communities and Local Government (MHCLG) has published its latest monthly remediation data for residential buildings over 11 metres in England. By the end of March 2026, remediation works had been completed on 35% of the 4,322 buildings identified with unsafe cladding, while works were actively underway on a further 21%. The next official data release is scheduled for 27 May. 

Although significant progress has been made since the introduction of the post-Grenfell remediation programmes, thousands of residents remain affected by ongoing safety works, temporary mitigation measures and project delays. Industry bodies continue to warn that regulatory capacity, funding pressures and application quality remain key factors influencing the pace of remediation delivery across the sector.
