Blown mineral wool insulation for Leicester properties
Our Leicestershire coverage takes in Leicester (LE1) and nearby Oadby, Wigston Magna and Loughborough. Leicester is one of the main towns we cover in Leicestershire.
A suitable wall in Leicester is usually filled in a single day from outside, with drill holes made good to match the pointing. For semi-detached and terraced homes in Leicester, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side.
Wind-driven rain is the first thing the surveyor weighs up. 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 the rules side, 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.

When is it not the right choice?
Very narrow or uneven cavities, walls with lots of mortar snots and debris, and some very exposed elevations can be better suited to bonded bead, which flows around obstructions and is certified for a wider range of exposure zones in some systems. The survey says which and why.
