Cavity insulation top-up for Leicester properties
Leicester sits in Leicestershire. We work across the LE1 district, including nearby Oadby, Wigston Magna and Loughborough.
Most Leicester houses built from the 1920s onwards have cavity walls, but the survey still checks each one: cavity width, debris, the condition of the brickwork and how exposed each wall is. Leicester properties with rendered or painted walls get a closer look at the outer finish, because cracked render can let rain behind it.
Before any material is chosen, exposure is checked. Much of Leicestershire 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 Leicester 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.

How do I know if my walls need a top-up?
Cold patches on internal walls, a thermal image showing uneven heat loss, or an EPC that says 'filled cavity' when parts of the house feel colder are all signs. Extensions are a common cause: the new wall is insulated as built, but the old wall it joins may have been left partly empty.
