Cavity wall insulation for flats for Lerwick properties

Our Highlands and Islands coverage takes in Lerwick (ZE1). Island addresses are surveyed by arrangement.

For landlords and managing agents in Lerwick, we survey in batches and return a result sheet and fixed price per address. For commercial buildings in Lerwick, the survey also considers building use and fire requirements before a material is specified.

Local weather affects which walls can be filled. Parts of the Highlands and Islands face some of the heaviest wind-driven rain in the UK, especially exposed coastal and upland sites. Here the survey is stricter: some walls suit only certain certified systems, and some should not be filled at all.

On the rules side, in Lerwick no building warrant is needed for insulation within a wall, but the work must meet the building standards.

Funding in Scotland

In Scotland, Home Energy Scotland is the route to the Home Energy Scotland Grant and Loan and Warmer Homes Scotland.

Why one flat cannot usually be done alone

The cavity runs continuously across the building. The Energy Saving Trust notes that flats need agreement from the whole block. Filling one flat's walls in isolation leaves gaps, and the freeholder normally owns the structure.
