Cavity wall insulation for Oadby properties
Our Leicestershire coverage takes in Oadby (LE2) and nearby Wigston Magna, Leicester and Loughborough. It is around 3 miles south-east of Leicester.
Oadby properties with rendered or painted walls get a closer look at the outer finish, because cracked render can let rain behind it. Where an Oadby property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed.
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.
On compliance, in Oadby 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.

Is my wall suitable for cavity wall insulation?
Most homes built from the 1920s onwards have cavity walls, but having a cavity is not the same as being suitable. The Energy Saving Trust's rule of thumb is a cavity of at least 50mm, clear of rubble, behind masonry in good condition, on a wall that is not exposed to severe driving rain or flood risk.
