Question to the Ministry of Housing, Communities and Local Government:

To ask the Secretary of State for Housing, Communities and Local Government, how many small and medium-sized housebuilders face building safety remediation liabilities.

The Government has been clear that those responsible for unsafe buildings should contribute towards the cost of fixing them. As of March 2025, the Government estimated that it will cost between £11.8bn and £22.7bn to remediate residential buildings 11 metres and above in height that have or had unsafe cladding in England.

Under the Developer Remediation Contract (DRC), 53 major developers have committed to fix or pay to fix over 2,600 buildings at a cost to themselves of around £4.2bn.

Where a building which was not developed by one of the 53 major developers requires cladding remediation, the Government has committed to grant funding. Under the terms of the grant funding agreement, the applicant is required to pursue reasonable cost recovery efforts from third parties, including developers where appropriate.

In addition, the Government is taking legal action to recover costs from those responsible using powers in the Building Safety Act 2022. For example, in May 2026 the department secured a remediation contribution order for £3.7m from a developer responsible for a building in London which the taxpayer had paid to remediate.

The Government does not publish data on the number of small and medium housebuilders who have building safety remediation liabilities. Data on the liabilities of developers under the Developer Remediation Contracts is published on gov.uk here.

The wider housebuilding sector will contribute to remediation costs through the Building Safety Levy, which comes into force from 1 October 2026. Measures within the levy to support smaller developers include an exemption for developments of fewer than 10 units, a 50% discount for new developments on previously developed land and an exemption for affordable housing.

The Government keeps the impact of building safety measures on housing delivery under review.
