Commercial cavity wall insulation for Norwich properties
If your property is in Norwich or the NR1 district or nearby Great Yarmouth, Thetford and King's Lynn, it is within our Norfolk coverage. Norwich is one of the main towns we cover in Norfolk.
For commercial buildings in Norwich, the survey also considers building use and fire requirements before a material is specified. Blocks of flats in Norwich are surveyed as a whole, because the cavity runs across every flat in the building.
Exposure matters for every cavity wall. Much of Norfolk 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 Norwich 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.

What is different on commercial jobs
Access is planned around opening hours, often with towers or MEWPs. Material choice takes account of building use and fire requirements, so non-combustible mineral wool is often specified. Work is usually standard-rated for VAT unless the building qualifies for a relief, which we confirm on the quote.
