Before we quote in Streatham
As well as Streatham itself, we quote in Mitcham, Brixton and Wimbledon. 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 Streatham, we programme the work around opening hours so the building can keep trading.

Permissions in England
Planning in Streatham follows England's national rules: similar-looking finishes on houses are usually permitted, while flats, commercial premises, conservation areas and streets under an Article 4 direction need an application.
Building control applies once more than half of a wall is insulated or re-rendered, or more than a quarter of the whole building envelope, and your written quote says how that's handled.
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 Streatham: 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.
Can the building stay open during the works?
Usually, yes. The work is phased and the scaffold layout keeps entrances and escape routes clear.
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 Streatham?
Yes — we survey and quote commercial external wall insulation in Streatham (SW16) and nearby Mitcham, Brixton and Wimbledon, with a fixed written price before any work starts.
