Maidstone: walls, weather and approvals
We also cover Chatham and Rochester, close to Maidstone. Homes across the South East range from inter-war semis and post-war estates, which are mostly cavity-walled, to older solid-walled cottages and Victorian town terraces.
Much of Kent 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.
For terraced homes in Maidstone with attractive brick fronts, one approach is to insulate the front internally and the rear externally.

Approvals in England
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 Maidstone: 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.
