Local considerations in March
We cover March and nearby Wisbech, Peterborough and King's Lynn. March is about 14 miles from Peterborough. 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 Cambridgeshire 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.
Where a property in March is in a conservation area or the front elevation must stay unchanged, internal insulation is often the practical route.

England: planning and regulations
Planning isn't usually involved with internal insulation. Building control is, once more than half of a wall is treated, and listed buildings need listed building consent.
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 March: 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.
Can I stay in the house?
Yes, but each room is out of use while it's worked on, typically 3–5 days.
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.

Yes — we survey and quote internal wall insulation in March (PE15) and nearby Wisbech, Peterborough and King's Lynn, with a fixed written price before any work starts.
