Brick slip EWI in Chiswick: questions
Do I need planning permission for external wall insulation in Chiswick?
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.
Do you cover Acton as well as Chiswick?
Yes. From Chiswick we also cover Acton, Barnes and Shepherds Bush, and the rest of Greater London.
How long will the work take in Chiswick?
Two to six weeks on site for most houses, depending on size: bungalows are quicker, detached houses longer, weather allowing. Render isn't applied in rain or frost.
