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.

Planning: Welsh guidance allows cladding a house without an application if the materials look similar to the original, but external wall insulation that projects more than 16cm from the wall needs planning permission. Any cladding or render in a conservation area, National Park, AONB or World Heritage Site needs permission, listed buildings need consent, and permitted development rights may have been removed by condition or Article 4 direction.
VAT: Installing insulation in a home is zero-rated for VAT until 31 March 2027, then 5%.

Brick slip EWI in Rhyl: questions

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

Wales has its own Building Regulations and Approved Document L. Renovating a large part of an external wall brings the energy standards into play, so building control approval is needed for EWI. We arrange it as part of the job.

How long will the work take in Rhyl?

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.

Which EWI system suits homes in Rhyl?

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