Underfloor insulation for Runcorn properties
If your property is in Runcorn or the WA7 district or nearby Widnes, Warrington and Ellesmere Port Town, it is within our Cheshire coverage. It is roughly 12 miles north-east of Chester.
We check ventilation as carefully as insulation in Runcorn homes, because both matter for keeping a house dry. In Runcorn homes this is often done on the same visit as a cavity fill, which saves a second trip.
For regulations, if cavity wall insulation follows in Runcorn, 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.

Keeping the void ventilated
Air bricks under a suspended floor must stay clear so the timbers stay dry. Insulation goes between the joists, not across the void, and gaps at skirtings are sealed to stop draughts.
