Brick slip EWI in Gerrards Cross: questions
Is building control approval needed for brick slip external wall insulation in Gerrards Cross?
Insulating more than half of a wall, or more than a quarter of the whole building envelope, counts as renovating a thermal element under the Building Regulations, so the wall should reach 0.30 W/m²K where that is technically, functionally and economically feasible, and building control must be involved. We arrange it as part of the job.
