Wimbledon: walls, weather and approvals
As well as Wimbledon itself, we quote in Morden, Mitcham and Putney. London's housing includes a large stock of Victorian and Edwardian solid-wall terraces, inter-war semis and post-war blocks, and conservation areas cover many streets — so planning is often the first question for external work.
Much of Greater London 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 Wimbledon 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.
What are the options for internal insulation?
- Insulated plasterboard — PIR or phenolic foam bonded to plasterboard, fixed to the wall and skimmed. Thinnest option.
- Insulated stud wall — a timber or metal frame filled with insulation, with a vapour control layer and plasterboard. Takes more space but runs services easily.
- Wood fibre and lime — breathable boards finished in lime plaster, for older walls that need to manage moisture.

Internal wall insulation in Wimbledon: questions
Can I stay in the house?
Yes, but each room is out of use while it's worked on, typically 3–5 days.
How much room space will I lose?
Usually 50–100mm on each insulated wall, depending on the system.
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.
