What is brick slip external wall insulation?

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 Lancaster: questions

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

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.

How long will the work take in Lancaster?

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.

Which EWI system suits homes in Lancaster?

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