Underfloor insulation for Eastbourne properties
If your property is in Eastbourne or the BN21 district or nearby Hailsham, Seaford and Bexhill-on-Sea, it is within our East Sussex coverage. It is around 19 miles east of Brighton.
In Eastbourne homes this is often done on the same visit as a cavity fill, which saves a second trip. Small measures like this are often among the cheapest per pound saved, and they suit Eastbourne homes of every age.
On compliance, if cavity wall insulation follows in Eastbourne, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

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.
