Brick slip EWI in Abingdon: questions

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

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.

Are there grants for external wall insulation in Abingdon?

Low-income households in homes rated below EPC C can apply for Warm Homes: Local Grant where their council is taking part. The Great British Insulation Scheme closed on 31 March 2026, and ECO4 closes on 31 December 2026; its final months are for finishing and putting right existing work. Grant schemes use their own approved installers, so check a scheme's installer rules before booking; our quotes are for privately funded work unless we confirm otherwise in writing.

How long will the work take in Abingdon?

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.
