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.

How long does external wall insulation take?

Can I stay at home during the work?
