On 1 June 2022, the Government published a response to a consultation following the review of the ban of combustible materials in and on the external walls of buildings. The consultation proposed a temporary 18-month relaxation of the ban as it relates to cavity trays. This followed from issues highlighted to officials on the excessive cost, supply (including of trained professional able to install these products) and installation of products on the market at the time. At the time we brought in the changes we considered it appropriate, on balance, to allow for a short-term exemption for combustible cavity trays as the risk they pose remains relatively low while providing temporary flexibility. The consultation response is available here. We will continue to review the impact of the ban including this short-term exemption and to work with industry to understand new products available on the market.
