Brick slip external wall insulation in Corby

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.

Rules that apply in Corby
- 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 Corby: questions
Is building control approval needed for brick slip external wall insulation in Corby?
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 Uppingham as well as Corby?
Yes. From Corby we also cover Uppingham, Kettering and Market Harborough, and the rest of Northamptonshire.
Which EWI system suits homes in Corby?
It depends on the walls. Most brick houses in Corby 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.
