Homes and walls in Redhill
We cover Redhill and nearby Reigate, Horley and Caterham. Redhill sits around 18 miles from Woking. 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.
We provide drawings and finish samples for planning applications on Redhill commercial buildings.

Planning and building control in England
Before quoting in Redhill, we check whether the property is in a conservation area, under an Article 4 direction or listed, because that decides whether changing the outside needs planning permission.
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.
On residential buildings with a storey 11 metres or more above ground, guidance points to non-combustible external wall materials, and combustible materials are banned in relevant buildings 18 metres and over, so we specify mineral wool systems there.
Which system suits a commercial building?
The building's height, use (for example, residential or assembly use) and fire strategy shape the choice. Mineral wool systems are typical for multi-storey and public buildings; EPS may suit single-storey units. The system manufacturer's classification is confirmed in writing.

Commercial EWI in Redhill: questions
Do you handle the planning application?
We provide the technical information, drawings and samples an application needs; your agent or our designer can submit it.
Is VAT 0% on commercial insulation?
Usually not. The zero rate covers insulation installed in residential accommodation and, since 1 February 2024, buildings used solely for a relevant charitable purpose, such as many charity-run village halls. Other commercial work is standard-rated.
Can the building stay open during the works?
Usually, yes. The work is phased and the scaffold layout keeps entrances and escape routes clear.
Do you cover Redhill?
Yes — we survey and quote commercial external wall insulation in Redhill (RH1) and nearby Reigate, Horley and Caterham, with a fixed written price before any work starts.
