Tottenham: walls, weather and approvals
Surveys in Tottenham also cover the surrounding N17 district and towns such as Edmonton and Wood Green. 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.
We provide drawings and finish samples for planning applications on Tottenham commercial buildings.

Permissions in England
Planning in Tottenham 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.
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 Tottenham: 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.
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.
