External Wall Insulation in Woking
Based in Ash Vale — about 20 minutes from Woking
Woking’s solid-wall stock around Maybury, older Old Woking streets and parts of St John’s bleeds heat. EWI cuts that heating bill materially.
EWI in Woking runs £130–£190 per m² installed; solid-wall homes around Maybury and Old Woking are exactly the stock where grants of up to £15,000 usually apply.
Woking's older housing away from the high-rise town centre — Victorian, Edwardian and inter-war housing under Woking Borough Council in the GU21 and GU22 postcodes — is genuinely solid-wall, pre-cavity construction in large parts of the borough, and it's the town where our EWI specification work has been most consistent of anywhere we cover.
That's part of why Woking is the one town on our patch where we quote monocouche, silicone and external wall insulation in roughly equal measure, rather than one system dominating — the mix of housing ages here genuinely calls for all three. We're around 20 minutes from Woking, home to the Shah Jahan Mosque and the H.G. Wells Martian tripod statue.

External wall insulation costs £130–£190 per m² including labour and materials, depending on insulation thickness, system choice and access. Grants of up to £15,000 are available for qualifying homes, and the Energy Saving Trust estimates £300–£500 annual heating savings on a semi-detached property.
EWI fixes 60–150mm of insulation board (EPS, mineral wool or phenolic) to the outside of your walls and renders over the top. On a solid-wall home it typically cuts heating bills by 25–40% — the Energy Saving Trust estimates £300–£500 a year on a semi-detached property.
EWI on a semi-detached property takes about two weeks. Thin-coat silicone rendering is typically completed in a week, and monocouche spray render takes just 3–4 days on a semi-detached house thanks to the efficiency of the spray pump.
Usually not — re-rendering in a similar finish falls under permitted development for most houses. You DO need consent if the property is listed, in a conservation area with an Article 4 direction, or a flat. External wall insulation that changes the appearance may also need approval — we advise on this at survey, free of charge.
