The Building Safety Remediation data release is a crucial tool for monitoring the progress of residential buildings over 11 metres tall with unsafe cladding in England. The update monitors the wider progress of a large-scale remediation action plan.
As of 31st July 2025, there were 5,214 residential buildings of 11 metres and over in height identified with unsafe cladding.
The remediation progress reported an increase of 24 since the end of June 2025. That means an estimated 61%-91% of all buildings of 11 metres and over in height are expected to be remediated as part of MHCLG’s (Ministry of Housing, Communities and Local Government) remediation schemes.
1,417 more buildings with unsafe cladding have been added to the list since the department first began reporting on all five remediation programmes in October 2023.
So far, 2,502 buildings (48%) have either started or completed remediation works. Of these, 1,780 buildings (34%) have completed remediation works.
To help facilitate the remediation progress, 3B Training has developed Rainscreen Façade Systems training courses in conjunction with CITB.
Before we go any further with the updated figures, let’s explain what the government’s remediation action plan is.
The Remediation Acceleration Plan (RAP) – announced 2nd December 2024 – is the government’s attempt to resolve delays in cladding remediation of residential buildings over 11 metres high.
Following the Grenfell fire in 2017, the government has taken many steps to compel building owners to identify and remediate fire safety defects in the external walls of their buildings.
The approach has evolved over time, with the creation of the government-backed remediation fund in 2020 (called the Building Safety Fund). Then the Building Safety Act was introduced in 2022 introduction, bringing extended limitation periods and new rights of action against relevant parties.
In early 2023, remediation contracts were introduced to which developers agreed to meet remedial costs for their buildings.
The scope of the buildings and defects covered has expanded over this period. There are up to 10,000 buildings nationally where remedial works have not yet concluded.
Furthermore, there are buildings which have been remediated which must be remediated again due to incorrect workmanship.
RAP focuses on forcing developers and those with obligations to repair properties (landlords and freehold owners) to speed up remediation.
The government has identified barriers to making buildings safe, including:
The objectives of the RAP are:
Landlords face severe penalties if, by the end of 2029, buildings over 11 metres high with unsafe cladding have not been remediated. Also, if a completion date for remedial works has not been set.
Criticism has been levied at developers who signed up to the developer remediation pledge but have so far failed to progress remedial works in accordance with the agreements.
A group of major developers met with the government in November 2024 to discuss the problems with remediation. They made 35 commitments in a joint remediation plan. These commitments range of areas, such as improving resident experience of remedial works, plus accelerating efforts to find all unsafe buildings which need remedial work.
The joint plan contains ambitious targets, including:
To facilitate the progress of remediation, the government proposed to legislate by:
Whether RAP will be successful will only be evidenced by the ongoing progress of remediation to the identified unsafe buildings.
As of 31st July 2025, 511 high-rise residential and publicly owned buildings were identified as being unlikely to meet building safety regulations. No change from the end of June.
The Building Safety Fund (BSF) was a UK government scheme, which provided funding to address dangerous cladding on high-rise buildings (over 18m high) in England to help resolve fire safety risks. The BSF was closed to applications on 1st September 2025.
The BSF’s goal was to protect leaseholders from having to pay for the costly replacement of unsafe cladding and insulation.
The BSF has been replaced by the Cladding Safety Scheme (CSS), which funds remediation for all buildings over 11m high, including medium-rise buildings that were not covered by the original BSF.
As of 31st July 2025, 70% of buildings which applied for BSF funding have started or completed remediation, with 55% having completed remediation.
The Cladding Safety Scheme (CSS) was launched in July 2023.
The CSS meets the cost of addressing life safety fire risks associated with cladding on residential buildings over 11 metres in height in England.
Applications for the CSS are made through the Building Remediation Hub, which is managed by Homes England.
An application for the CSS can be submitted by the person or organisation legally responsible for the building’s external repairs or their representative.
As of 31st July 2025, there are 5,043 buildings at various stages of the Cladding Safety Scheme (289 with live applications and 782 which are eligible). 142 buildings have started or completed works, with 49 having completed works.
Developer-Led Remediation refers to the UK government’s program, the Developer Remediation Contract (also known as the Developer Pledge). The Developer Remediation Contract requires developers of residential buildings over 11 metres to directly address or fund the remediation of fire-safety defects, such as unsafe cladding, which they were responsible for.
This approach holds developers accountable for past projects to ensure buildings are made safe and taxpayers are reimbursed for any government funds previously spent on fixing life-critical defects.
When excluding buildings reported to have only non-cladding defects, there are 1,527 buildings which developers have reported as having unsafe cladding.
Win the main, self-reported information covers buildings to be remediated by the developer rather than being remediated through a government fund and being reimbursed to taxpayers. However, some buildings being remediated under a government remediation programme will be included if other relevant fire safety defects have been discovered.
Developers have self-reported 1,892 buildings which require life-critical fire safety remediation.
Data released in the recent Building Safety Remediation monthly data release is correct as of 31st March 2025 in relation to data from Registered Providers of Social Housing. Data from other programmes is correct as of 31st July 2025.
On the 31st July 2025, 44% of social buildings identified as having unsafe cladding have begun or completed remediation works. 34% of identified buildings have completed remediation works.
There is still a lot of building safety remediation work to be completed to ensure high-rise buildings over 11 metres tall are safe for residents. What is crucial if for rainscreen façade systems to be installed correctly, so that remediated buildings are safe to inhabit.
