Homes and walls in Holloway
We cover Holloway and nearby Highbury, Archway and Chalk Farm. 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 blocks in Holloway, we start with height, storeys and the planning position, because those decide the system.

England: planning and regulations
Planning in Holloway 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.
Who needs to agree to EWI on a block?
The freeholder or management company commissions the work, but leaseholders usually pay through the service charge. In England and Wales, major works above the statutory threshold trigger the Section 20 consultation process before a contract is placed. We provide the specification and pricing you need for that consultation.

Flats and blocks in Holloway: questions
Do you work on high-rise buildings?
Tell us the height and number of storeys. Buildings in the higher-risk category have a separate regulatory route, and we'll say plainly if we're not the right contractor.
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.
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.
Do you cover Holloway?
Yes — we survey and quote EWI for flats and blocks in Holloway (N7) and nearby Highbury, Archway and Chalk Farm, with a fixed written price before any work starts.
