Cavity wall insulation for flats for Dunstable properties

We cover Dunstable and the LU6 postcode district, including nearby Luton, Leighton Buzzard and Ampthill. It is roughly 17 miles south of Bedford.

For commercial buildings in Dunstable, the survey also considers building use and fire requirements before a material is specified. Blocks of flats in Dunstable are surveyed as a whole, because the cavity runs across every flat in the building.

Every elevation is judged on its own exposure. Much of Bedfordshire sits in the more sheltered driving-rain zones of the UK, which widens the choice of fill. Exposed elevations, coastal sites and high ground still get checked wall by wall.

As for paperwork, in Dunstable 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.

Fire and height

For blocks, the material must suit the building's height and use. Non-combustible mineral wool is the usual choice; we confirm the system and its certificate limits in writing.
