Government response

●UK Government · Accepted in part · 26 Feb 2025

Words of: HM Government, Grenfell Tower Inquiry Phase 2 Report: Government response (CP 1248), presented to Parliament by the Deputy Prime Minister and Secretary of State for Housing, Communities and Local Government, 26 February 2025

The government accepts this recommendation in principle. Any claims made about a product’s performance, including statements about its suitability for use in certain situations, must be clear, honest and evidenced. Test results relied on when placing a product on the market should be accessible and free of charge to those selecting and using the product. Further, the national regulator must have powers to mandate disclosure of any information relating to the testing process that it considers necessary to assure itself that a product complies with the law. We have published a construction products green paper alongside the response to the Inquiry that proposes extensive measures for system-wide reform, including measures to address product testing and conformity assessment.

Site note: This is the government's response to the Phase 2 report (CP 1248, published 26 February 2025). It prints each recommendation and then the response to it. Where the recommendation is addressed to a body outside government, the response prints that body's own acceptance (the Architects Registration Board and RIBA, HMICFRS, London Fire Brigade, the National Fire Chiefs Council, the British Standards Institution, the National Police Chiefs' Council), and the row is filed under that body.

●Ministry of Housing, Communities and Local Government · 10 Sep 2026

In February 2026, the government published the Construction Products Reform White Paper and consulted on a General Safety Requirement for Construction Products, with the consultations closing in May. The consultations received responses from across the sector, supported by engagement across the product supply chain. We are now considering these responses and are continuing to work with industry and regulators to refine our proposals for reform.

We intend to publish government responses to the white paper and General Safety Requirement consultations later in the year, setting out more detail on next steps. These next steps include our intention to bring forward legislation to introduce a General Safety Requirement when Parliamentary time allows.

In February 2025, alongside the government response, we published a Construction Product Reform Green Paper setting out proposed reforms to the sector. We conducted detailed analysis of the responses and undertook engagement with the sector to develop more detailed proposals.

Informed by this, the government has published the Construction Products Reform White Paper and a consultation on the details of a General Safety Requirement alongside this report. The white paper sets out the government’s response to the green paper and next steps for long term system-wide reform. The General Safety Requirement consultation sets out the proposed approach to bring unregulated products into the regulatory regime.
