What is brick slip external wall insulation?

Rules that apply in Newquay

Planning: 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.
VAT: Installing insulation in a home is zero-rated for VAT until 31 March 2027, then 5%.

Brick slip EWI in Newquay: questions

Is building control approval needed for brick slip external wall insulation in Newquay?

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.

Is VAT charged on brick slip external wall insulation in Newquay?

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 Newquay?

It depends on the walls. Most brick houses in Newquay 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.
