Cavity wall insulation for flats for Gainsborough properties
Our Lincolnshire coverage takes in Gainsborough (DN21) and nearby Scunthorpe and Lincoln. It is about 14 miles north-west of Lincoln.
Blocks of flats in Gainsborough are surveyed as a whole, because the cavity runs across every flat in the building. For landlords and managing agents in Gainsborough, we survey in batches and return a result sheet and fixed price per address.
Every elevation is judged on its own exposure. Much of Lincolnshire 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 Gainsborough 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.
