Brick slip EWI in Liverpool: questions

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

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 Birkenhead as well as Liverpool?

Yes. From Liverpool we also cover Birkenhead, Wallasey and Litherland, and the rest of Merseyside.

How long will the work take in Liverpool?

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.
