Homes and walls in Staines
Surveys in Staines also cover the surrounding TW18 district and towns such as Egham and Ashford (Surrey). Staines is about 8 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.
For commercial premises in Staines, we programme the work around opening hours so the building can keep trading.

England: planning and regulations
For a house in Staines, 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.
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.
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.
Does commercial EWI need planning permission?
Generally yes — permitted development rights for external wall changes are written for houses. Applications need elevations showing the projection, finish and colours, and details at eaves and openings.

Commercial EWI in Staines: questions
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 provide a maintenance plan?
Yes — the handover includes the system documents and recommended inspection and cleaning intervals.
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.
Do you cover Staines?
Yes — we survey and quote commercial external wall insulation in Staines (TW18) and nearby Egham, Ashford (Surrey) and Feltham, with a fixed written price before any work starts.
