Local considerations in Stornoway
We cover Stornoway and the wider Orkney, Shetland and the Western Isles; island and remote addresses are surveyed by arrangement. The Highlands and Islands have many exposed stone and harled homes, timber-framed houses and scattered rural properties.
Parts of Orkney, Shetland and the Western Isles fall in the higher wind-driven rain exposure bands, especially coastal and upland sites, so render specification, movement joints and detailing at cills, verges and the base of the wall matter more than usual.
We plan EWI in Stornoway around the details that cause trouble later — cills, eaves, downpipes and the base of the wall above the damp-proof course.

Permissions in Scotland
In Scotland, permitted development for external wall changes is narrower, so in Stornoway we check with the council's planning team where the appearance changes, and always for flats, tenements and conservation areas.
Over-cladding work in Scotland often needs a building warrant from the council's building standards service, with Section 6 of the Technical Handbooks setting insulation benchmarks.
What does the survey check before EWI is specified?
- Wall construction and condition, including any damp, cracking or loose render
- Ground levels and the damp-proof course, so the system starts above splash height
- Eaves depth, verges and whether the roofline needs extending
- Window positions, cill depths and reveal space
- Services on the wall: gas, electric meters, flues, soil pipes, satellite dishes and lights
- Planning and Building Regulations position for your property and nation

External wall insulation in Stornoway: questions
Can EWI go over pebble dash?
Usually yes. The dash is tested for adhesion and hollow areas; sound dash can be insulated over with additional mechanical fixings, while loose areas are removed first.
How much does external wall insulation cost?
Our guide price for EWI is £105–£170 per m² of wall depending on the system, plus scaffolding. A typical three-bed semi with EPS and silicone render comes to roughly £10,200–£17,700 for the whole house, including scaffold. Installing insulation in a home is zero-rated for VAT until 31 March 2027, so that's the total. You get a fixed written price after a free survey.
Does external wall insulation cause damp?
Not when it is specified and detailed properly. Problems usually come from poor detailing: no starter track above the damp-proof course, gaps at cills and penetrations, or a vapour-closed system on a wall that needs to breathe. The survey checks moisture, ground levels and the wall type before a system is chosen.
Do you cover Stornoway?
Yes — we survey and quote external wall insulation in Stornoway (HS1); island and remote addresses are surveyed by arrangement, with a fixed written price before any work starts.
