What we look for in Hayes
As well as Hayes itself, we quote in Southall, Heston and Greenford. 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.
For commercial premises in Hayes, we programme the work around opening hours so the building can keep trading.

Approvals in England
For a house in Hayes, 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.
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 Hayes: questions
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 handle the planning application?
We provide the technical information, drawings and samples an application needs; your agent or our designer can submit it.
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 Hayes?
Yes — we survey and quote commercial external wall insulation in Hayes (UB3) and nearby Southall, Heston and Greenford, with a fixed written price before any work starts.
