Brick slip external wall insulation in Grays
From Grays to South Ockendon and Gravesend, we plan brick slip external wall insulation around the house in front of us rather than a standard package, with guide prices online and a written quote after survey.

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 Grays
- 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%.
Checked October 2026. Rules change, so we confirm them for your address at survey.
Brick slip EWI in Grays: questions
Is building control approval needed for brick slip external wall insulation in Grays?
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.
Are there grants for external wall insulation in Grays?
Low-income households in homes rated below EPC C can apply for Warm Homes: Local Grant where their council is taking part. The Great British Insulation Scheme closed on 31 March 2026, and ECO4 closes on 31 December 2026; its final months are for finishing and putting right existing work. Grant schemes use their own approved installers, so check a scheme's installer rules before booking; our quotes are for privately funded work unless we confirm otherwise in writing.
