Cavity insulation for new builds and extensions across Tayside
We cover 4 towns in Tayside: Dundee, Perth, Arbroath and Forfar.
Exposure matters for every cavity wall. Tayside has a mix of moderate and more exposed sites. Hilltop, coastal and west-facing walls take the brunt of wind-driven rain, so the survey records exposure for each elevation before a material is chosen.
If a wall in Tayside is not suitable, for example because of an undiagnosed damp patch or a very exposed gable, you are told so in writing with the reason. A suitable wall in Tayside is usually filled in a single day from outside, with drill holes made good to match the pointing.
Building standards in Scotland
In Scotland, work associated with thermal insulating material within a wall is listed in schedule 3 of the Building (Scotland) Regulations as work that does not need a building warrant. It must still meet the building standards, so the survey still checks that the wall and the chosen material are suitable, including exposure to wind-driven rain.
Funding in Scotland
- Home Energy Scotland is the starting point for the Home Energy Scotland Grant and Loan and for Warmer Homes Scotland, which can include cavity wall insulation.
- Many councils also run area-based schemes for insulation in particular streets or estates.
- ECO4 runs until 31 December 2026 across Great Britain, including Scotland.

Extensions that join an older house
Where an extension meets an existing cavity wall, the junction is a weak point. We can borescope and fill the existing wall at the same time so the old and new walls perform together.
What is included
- Batts or boards to the specified U-value
