Brick slip external wall insulation in Colchester

What is brick slip external wall insulation?
Brick slip external wall insulation is an EWI system finished with 10–20mm thick clay brick slips, bonded with adhesive onto a reinforced basecoat over the insulation and then pointed. Corner slips return around external corners so the finish reads as solid brickwork.

Brick slip EWI in Colchester: questions
Do I need planning permission for external wall insulation in Colchester?
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 VAT charged on brick slip external wall insulation in Colchester?
Not on installing insulation in a home at the moment: that's zero-rated until 31 March 2027, after which the rate is due to be 5%. Work on commercial buildings is standard-rated.
Which EWI system suits homes in Colchester?
It depends on the walls. Most brick houses in Colchester 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.
