●UK Government — initial response
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.

Each entry above links to a primary source — gov.uk written statement, consultation response document, or inspection report. The Index does not characterise government intent; it tracks what has been published.
How this page is built
Source and Response are verbatim from primary documents. The Evidence trail records published activity since — written statements, consultation outcomes, inspection findings, parliamentary references. The Index does not paraphrase or characterise intent; it tracks what has been published. Where the evidence is the absence of action (a missed deadline, a slipped timetable), that absence is documented from primary sources rather than inferred.
This recommendation's data is verified periodically against primary sources. The Index is monitored for staleness weekly.
