Part of every quote
- Both can be done in stages, elevation by elevation or room by room

- External insulation keeps room sizes and treats cold bridges well
- In England and Wales, Building Regulations apply when more than half of a wall is treated
Before we quote in Woking
As well as Woking itself, we quote in Guildford, Egham and Walton-on-Thames. 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 Surrey 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 Woking homeowners weighing external against internal insulation, the survey sets out both with prices.

Approvals in England
For a house in Woking, external insulation or render is often permitted development if it looks similar to the existing walls; conservation areas, flats, commercial buildings and listed buildings need permission or consent, so we check your address first.
If the work covers more than half of a wall, or a quarter of the building's whole envelope, it counts as renovating a thermal element, with a target of about 0.30 W/m²K where feasible.
External or internal — which is better?
External insulation keeps the wall warm, reduces cold bridging at floors and party walls, renews the outside, and doesn't shrink rooms — but it changes the look and needs scaffolding. Internal insulation keeps the façade unchanged and can be done room by room, but loses 50–100mm of floor space per wall and needs careful detailing to avoid condensation at joists and corners.

Solid wall insulation in Woking: questions
Can I do one wall at a time?
Yes. Many owners start with the coldest or most exposed elevation, often a gable end.
Does solid wall insulation cause condensation?
It can if detailed poorly, particularly internally. A condensation risk check for the proposed build-up and careful detailing at joists, reveals and corners avoid it.
Can I get a grant for solid wall insulation?
Some schemes cover it for eligible households — for example ECO4 until 31 December 2026, Home Energy Scotland's grant and loan, Wales' Warm Homes Nest and NI's Affordable Warmth Scheme. Each has its own eligibility and installer rules; see our grants guide.
