Cavity wall insulation for flats for Renfrew properties

Renfrew is among the towns we cover in Renfrewshire and Inverclyde, alongside Paisley, Newton Mearns and Greenock. It is about 3 miles north-east of Paisley.

Work on Renfrew rented homes and blocks is booked around tenants and residents, with access arranged through your agent if you prefer. Per-address photo records for Renfrew properties make compliance files and EPC updates straightforward.

Wind-driven rain is the first thing the surveyor weighs up. Parts of Renfrewshire and Inverclyde 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 compliance, in Renfrew no building warrant is needed for insulation within a wall, but the work must meet the building standards.

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.
