Cavity wall insulation for flats for Shrewsbury properties

If your property is in Shrewsbury or the SY1 district or nearby Wellington and Telford, it is within our Shropshire coverage. Shrewsbury is one of the main towns we cover in Shropshire.

Blocks of flats in Shrewsbury are surveyed as a whole, because the cavity runs across every flat in the building. For landlords and managing agents in Shrewsbury, we survey in batches and return a result sheet and fixed price per address.

Before any material is chosen, exposure is checked. Shropshire 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.

As for paperwork, in Shrewsbury filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Funding in England

In England, ECO4 runs to 31 December 2026 and Warm Homes: Local Grant supports low-income households through councils.

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.
