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

To ask the Secretary of State for Housing, Communities and Local Government, if he will instruct the Building Research Establishment to design the BS 8414 tests on the fire performance of external cladding systems to reflect the worst-case scenario of a building fire.

Tests carried out using the BS 8414 methodology are designed using the established and recognised BS 8414 methodology. Rigs to be used in tests are constructed in line with standard industry practice to ensure compliance with Approved Document B guidance on the construction of external wall systems.
