Brick slip EWI in Barnstaple: questions

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

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.

Not on installing insulation in a home at the moment: that's zero-rated until 31 March 2027, after which the rate is due to be 5%. Work on commercial buildings is standard-rated.

How long will the work take in Barnstaple?

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.
