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.

Can brick slips match my existing bricks?
Slips come in a wide range of colours and textures, and a close match is often possible. An exact match to weathered Victorian brick is hard; we bring samples to the survey and you see them against your wall in daylight before ordering.
Why is a brick slip finish more expensive?
Slips are a material cost on their own, they are laid by hand course by course, corners need special pieces, and the whole face is pointed. Expect brick slip finishes to cost noticeably more per square metre than render.

The rules in Scotland
- Planning
- Changes to the external appearance of a house can need planning permission in Scotland, and flats, listed buildings and conservation areas always need checking with the council before EWI is ordered.
- Building regulations
- An external wall insulation cladding system on a house normally needs a building warrant under the Building (Scotland) Regulations; only minor like-for-like repairs to an existing system are exempt. Section 6 of the technical handbooks sets the energy standards.
- Fire safety
- Under section 2.7 of the domestic technical handbook, cladding on a building with any storey more than 11m above ground should be European Classification A1 or A2. Below that height, combustible cladding may be used more than 1m from a boundary, with tighter rules closer to it.
- Funding
- Home Energy Scotland Grant and Loan offers up to £7,500 grant plus a £2,500 interest-free loan for solid wall insulation, with a rural and island uplift. You need a valid EPC recommending the measure, a TrustMark-registered installer, and a written offer before work starts. Warmer Homes Scotland helps eligible low-income households through its own installers. Our quotes are for privately funded work unless we confirm in writing that we can carry out a funded job.

Questions about brick slip external wall insulation
Can brick slips go on mineral wool?
Yes, where the system holder certifies the combination. Mineral wool with brick slips is used on low-rise blocks.
How long do brick slips take?
Longer than render: allow extra days per elevation for laying and pointing.
Can I do the front in slips and the rest in render?
Yes. It is a common way to keep the street face in brick and control the cost.
