What is brick slip external wall insulation?

Brick slip EWI in Cambridge: questions
Do I need planning permission for external wall insulation in Cambridge?
On a house, external wall insulation is usually permitted development if the finish looks similar to the existing walls. Render or cladding on a house in a conservation area, National Park, National Landscape (AONB), the Broads or a World Heritage Site needs planning permission. Flats and maisonettes have no householder permitted development rights, listed buildings need listed building consent, and an Article 4 direction can remove rights locally.
Is building control approval needed for brick slip external wall insulation in Cambridge?
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.
Do you cover Newmarket as well as Cambridge?
Yes. From Cambridge we also cover Newmarket, Ely and Huntingdon, and the rest of Cambridgeshire.
