Homes and walls in Archway
We also cover Holloway and Muswell Hill, close to Archway. 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.
On mixed-tenure blocks in Archway, we agree access and resident notices with the managing agent before scaffold goes up.

England: planning and regulations
Before quoting in Archway, 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.
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.
What fire-safety rules apply?
For blocks with a storey 11 metres or more above ground, guidance points to external wall materials of limited combustibility, and combustible materials are banned in the external walls of relevant buildings 18 metres and over in England. Higher-risk buildings (18 metres or seven storeys and above, with at least two homes) go through the Building Safety Regulator. We specify non-combustible systems wherever these apply and tell you at enquiry stage if a building is outside our scope.

Flats and blocks in Archway: questions
Can one flat have external wall insulation on its own?
Rarely. The outside walls are usually owned by the freeholder, the result would look patchy, and planning is unlikely. Whole-building schemes are the norm.
Who pays for EWI on a leasehold block?
In England and Wales, usually the leaseholders through the service charge, depending on the lease, and the landlord must follow the Section 20 consultation process for major works.
Do flats need planning permission for EWI?
Yes. Permitted development rights for external alterations apply to houses, not flats or maisonettes, so an application is needed.
Do you cover Archway?
Yes — we survey and quote EWI for flats and blocks in Archway (N19) and nearby Holloway, Muswell Hill and Chalk Farm, with a fixed written price before any work starts.
