Conclusion (the committee's words)
Eight years on from Grenfell, we are concerned that MHCLG still does not know how many buildings have dangerous cladding, how much it will cost to address, or how long it will take. MHCLG’s latest estimate, that 9,000 to 12,000 buildings will need remediating at a total cost of between £12.6 billion and £22.4 billion, is very broad given the length of time that has passed since Grenfell and is now more than a year old. MHCLG asserts that it is working to narrow the range, but promised six–monthly updates have not materialised. This level of uncertainty means that MHCLG cannot know if it is on track to achieve value for money for residents and the taxpayer. PAS 9980, leaves too much open to interpretation and is resulting in disagreements over the extent of remediation required. Meanwhile, MHCLG’s data on the unit costs of remediation is based on the costs of remediating high–rise buildings under the more risk–averse standard pre–dating PAS

Treasury minutes: Government response to the Committee of Public Accounts on the Seventeenth report from Session 2024-25
Published 16 May 2025.
Summary written by Accountability Index from the government's response. It is not the government's own words.The government agrees with most of the Committee's recommendations on the remediation of dangerous cladding, with target dates between summer and December 2025, but disagrees with the recommendation on construction manufacturers paying a share of remediation costs.
- On the Remediation Acceleration Plan, the government agrees to update the Committee in Autumn 2025. It says it "has not seen significant evidence that non-cladding defects are slowing down remediation" but is committed to removing blockers.
- On construction manufacturers paying a share of remediation costs, the government disagrees. It says it is consulting on redress routes in the Construction Products Reform Green Paper and that leaseholders and tenants are protected from the cost of cladding remediation.
- The government will publish latest building number estimates "by the summer", but the timing of cost and completion date estimates "will depend on the outcome of the forthcoming Spending Review".
- On insurance, the government agrees and will share an update on progress by the end of 2025. It is gathering data on premiums and is considering whether government "might support industry to reduce fire related liabilities".
