What is brick slip external wall insulation?

Rules that apply in Durham

Planning: On a house, external wall insulation is usually permitted development if the finish looks similar to the existing walls.

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.

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.
