Question to the Department for Levelling Up, Housing & Communities:

To ask the Secretary of State for Communities and Local Government, if his Department will require the Building and Research Establishment to (a) report measurement of smoke development and smoke toxicity from the recent post-Grenfell Tower tests it has conducted and (b) publish all past test information results it holds.

Smoke development and smoke toxicity is not a feature of either the screening or large-scale tests conducted for DCLG, so was not measured.

Following a request from DCLG, the Building Research Establishment (BRE) agreed to contact customers for whom they had carried out large-scale testing previously. If a customer gives permission, the BRE provides summary details of the test on their website (www.bre.co.uk/regulatory-testing).
