Heat load surveys and system design in Stornoway
No two rooms in Stornoway gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. In the Highlands, Islands and the North East of Scotland, systems are sized for cold winter days first.
For self-builds and extensions in Stornoway, a standalone design pack can go straight to your builder. We cover Stornoway and the rest of Orkney, Shetland and the Western Isles, including Kirkwall and Lerwick. Postcode districts we cover here include HS1.

Planning and permissions
Outdoor units on Scottish homes can often be installed without a planning application, but the conditions differ from England's, so we confirm the rules for your property at survey.
The survey
Where travel is involved, we agree the survey arrangements and any travel cost up front. On the day, the engineer measures the rooms, checks the electrics and agrees the outdoor unit position with you. In Stornoway we often start with photos, room measurements and the make of any existing system, so the survey visit is focused and any travel cost can be quoted in writing first.
