What we look for in Norwich
Surveys in Norwich also cover the surrounding NR2 district and towns such as Dereham and Great Yarmouth. 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.
We plan internal insulation in Norwich homes room by room so you keep the rest of the house usable.

England: planning and regulations
Internal insulation rarely needs planning permission, but in England and Wales insulating or replastering more than half of a wall's area involves building control, and listed buildings need consent for internal changes that affect their character.
Do I need Building Regulations approval?
Yes, in England and Wales once you insulate or replaster more than half of a wall's area (or more than a quarter of the building's whole envelope), it's treated as renovating a thermal element. The wall should reach about 0.30 W/m²K where practical, and building control needs to be involved.

Internal wall insulation in Norwich: questions
What happens to my radiators and sockets?
They're taken off and refitted on the new wall face. Electrical work is done by a qualified electrician.
How much room space will I lose?
Usually 50–100mm on each insulated wall, depending on the system.
Is internal insulation cheaper than external?
Per m² usually yes, but the cost of moving fittings and redecorating narrows the gap on whole-house jobs.
Do you cover Norwich?
Yes — we survey and quote internal wall insulation in Norwich (NR2) and nearby Dereham, Great Yarmouth and Lowestoft, with a fixed written price before any work starts.
