Question to the Department for Business and Trade:

To ask the Secretary of State for Business and Trade, whether the Office for Product Safety and Standards has made an estimate of the number of constructions using (a) Mica, (b) Pyrite and (c) other defective building materials in Northern Ireland.

The Office for Product Safety and Standards was appointed by MHCLG in April 2021 as the national regulator of construction products, overseeing conformity of construction products with designated standards under the Construction Products Regulations 2013. In this role, OPSS has not made any estimates of the number of constructions in Northern Ireland using Mica, Pyrite or defective materials.
