Before we quote in Surbiton
Surveys in Surbiton also cover the surrounding KT5 district and towns such as New Malden and Esher. 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.
Where one half of a pair in Surbiton is insulated and the other isn't, we detail the boundary so the neighbour can join later.

England: planning and regulations
Planning in Surbiton follows England's national rules: similar-looking finishes on houses are usually permitted, while flats, commercial premises, conservation areas and streets under an Article 4 direction need an application.
Insulating or re-rendering more than half of a wall's area brings in Part L of the Building Regulations, so building control is notified and the wall is upgraded to about 0.30 W/m²K where practical.
What does the work involve?
After checking the wall condition, any spalling concrete or corroded steel is reported before boards go on. Fixings are chosen for the substrate — concrete, steel-framed panels or mixed constructions — and the system is detailed around eaves, cills and the junction with neighbouring properties, which may not be insulated.

Non-traditional houses in Surbiton: questions
Can you insulate a Wimpey no-fines house?
Yes. No-fines houses have solid poured-concrete walls with no cavity, so EWI is the usual route. The survey checks the concrete condition first.
What if my neighbour isn't insulating?
We finish the system neatly at the boundary with a closing detail so the neighbouring house isn't affected and can be joined later.
Will EWI make my house mortgageable?
It can make a house more attractive and better insulated, but it does not replace a certified structural repair where a lender requires one. Ask your lender before relying on it.
Do you cover Surbiton?
Yes — we survey and quote non-traditional house insulation in Surbiton (KT5) and nearby New Malden, Esher and Morden, with a fixed written price before any work starts.
