What the job covers

Local considerations in Stornoway
Surveys in Stornoway (HS1) are arranged around travel to the wider Orkney, Shetland and the Western Isles. 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.
For Stornoway homeowners weighing external against internal insulation, the survey sets out both with prices.

Planning and building control 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.
Where a building warrant is needed for Stornoway work, it's obtained before installation starts, and the quote says who arranges it.

Solid wall insulation in Stornoway: questions
Can I get a grant for solid wall insulation?
Some schemes cover it for eligible households — for example ECO4 until 31 December 2026, Home Energy Scotland's grant and loan, Wales' Warm Homes Nest and NI's Affordable Warmth Scheme. Each has its own eligibility and installer rules; see our grants guide.
Is solid wall insulation worth it?
For many solid-walled homes it's one of the biggest single improvements to comfort, because the walls are often the largest heat-loss area. Savings depend on the home and heating, so we don't promise a figure.
Does solid wall insulation cause condensation?
It can if detailed poorly, particularly internally. A condensation risk check for the proposed build-up and careful detailing at joists, reveals and corners avoid it.
Do you cover Stornoway?
Yes — we survey and quote solid wall insulation in Stornoway (HS1); island and remote addresses are surveyed by arrangement, with a fixed written price before any work starts.
