Brick slip EWI in Heswall: questions

How much should I budget for brick slip external wall insulation in Heswall?

Budget around £185–£265 per square metre of wall for the system and finish, plus scaffolding priced per house. The survey measures your walls in Heswall and fixes the total in writing.

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

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.

Which EWI system suits homes in Heswall?

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