Homes and walls in Norwich
As well as Norwich itself, we quote in Dereham, Great Yarmouth and Lowestoft. The East of England has a mix of post-war estates, inter-war semis and older solid brick and flint cottages, with some system-built council homes on post-war estates.
Much of Norfolk sits in the lower wind-driven rain exposure bands, which keeps the choice of finishes wide — though hilltop, coastal and exposed gable walls can still need a tougher specification, so we check the actual site.
Schools and community buildings around Norwich are usually phased by elevation, with noisy stages in holidays where possible.

Planning and building control in England
Before quoting in Norwich, we check whether the property is in a conservation area, under an Article 4 direction or listed, because that decides whether changing the outside needs planning permission.
Building control applies once more than half of a wall is insulated or re-rendered, or more than a quarter of the whole building envelope, and your written quote says how that's handled.
On residential buildings with a storey 11 metres or more above ground, guidance points to non-combustible external wall materials, and combustible materials are banned in relevant buildings 18 metres and over, so we specify mineral wool systems there.
Which system suits a commercial building?
The building's height, use (for example, residential or assembly use) and fire strategy shape the choice. Mineral wool systems are typical for multi-storey and public buildings; EPS may suit single-storey units. The system manufacturer's classification is confirmed in writing.

Commercial EWI in Norwich: questions
Do you provide a maintenance plan?
Yes — the handover includes the system documents and recommended inspection and cleaning intervals.
Is VAT 0% on commercial insulation?
Usually not. The zero rate covers insulation installed in residential accommodation and, since 1 February 2024, buildings used solely for a relevant charitable purpose, such as many charity-run village halls. Other commercial work is standard-rated.
Can the building stay open during the works?
Usually, yes. The work is phased and the scaffold layout keeps entrances and escape routes clear.
Do you cover Norwich?
Yes — we survey and quote commercial external wall insulation in Norwich (NR2) and nearby Dereham, Great Yarmouth and Lowestoft, with a fixed written price before any work starts.
