Brick slip EWI in Norwich: questions
How much should I budget for brick slip external wall insulation in Norwich?
Budget around £185–£265 per square metre of wall for the system and finish, plus scaffolding priced per house. The survey measures your walls in Norwich and fixes the total in writing.
Do I need planning permission for external wall insulation in Norwich?
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.
Which EWI system suits homes in Norwich?
It depends on the walls. Most brick houses in Norwich suit EPS with silicone render; older stone or lime-built walls suit wood fibre or insulating lime render; and blocks need mineral wool. The free survey recommends one and explains why.
