Cavity wall insulation for landlords for Newtown properties

Newtown sits in Powys. We work across the SY16 district, including nearby Welshpool and Llandrindod Wells.

For landlords and managing agents in Newtown, we survey in batches and return a result sheet and fixed price per address. Work on Newtown rented homes and blocks is booked around tenants and residents, with access arranged through your agent if you prefer.

Local weather affects which walls can be filled. Parts of Powys 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 Newtown filling a cavity is notifiable work under the Building Regulations as they apply in Wales, usually self-certified through a competent person scheme.

Funding in Wales

In Wales, Warm Homes Nest offers free improvements to eligible low-income households, and ECO4 runs to 31 December 2026.
