What is brick slip external wall insulation?

Rules that apply in Bolton

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 Bolton: questions

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

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 Farnworth as well as Bolton?

Yes. From Bolton we also cover Farnworth, Westhoughton and Radcliffe, and the rest of Greater Manchester.

How long will the work take in Bolton?

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.
