Cavity wall insulation for flats for Denton properties
If your property is in Denton or the M34 district or nearby Hyde, Dukinfield and Droylsden, it is within our Greater Manchester coverage. It is about 5 miles east of Manchester.
For commercial buildings in Denton, the survey also considers building use and fire requirements before a material is specified. Blocks of flats in Denton are surveyed as a whole, because the cavity runs across every flat in the building.
Local weather affects which walls can be filled. Greater Manchester 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.
On the rules side, in Denton 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.
