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

To ask the Secretary of State for Communities and Local Government, how the combustibility testing regime being used to test samples of building materials as a result of the Grenfell Tower fire was chosen.

On 30 June, we published a note at: https://www.gov.uk/government/publications/explanatory-note-on-safety-checks-and-testing

This note sets out how the screening methodology for testing of cladding was chosen. On 6 July we then published details of further tests to be carried out as the next step in helping landlords to ensure the safety of their buildings. These large scale tests will help establish how different types of Aluminium Composite Material (ACM) panels, in combination with different types of insulation, behave in a fire. Further detail about the next testing stage can be found at https://www.gov.uk/government/news/expert-panel-recommends-further-tests-on-cladding-and-insulation
