What is brick slip external wall insulation?
Brick slip external wall insulation is an EWI system finished with 10–20mm thick clay brick slips, bonded with adhesive onto a reinforced basecoat over the insulation and then pointed. Corner slips return around external corners so the finish reads as solid brickwork.

Brick slip EWI in Newton-le-Willows: questions
Is building control approval needed for brick slip external wall insulation in Newton-le-Willows?
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 Newton-le-Willows?
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.
Which EWI system suits homes in Newton-le-Willows?
It depends on the walls. Most brick houses in Newton-le-Willows 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.
