Before we quote in Finchley
We cover Finchley and nearby Muswell Hill, Cricklewood and Kilburn. 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.
EPS is a common choice for two-storey houses, mainly on cost and weight, and we price it alongside mineral wool for homes in Finchley.

England: planning and regulations
For a house in Finchley, 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.
When is EPS the right choice?
EPS suits most two-storey houses, bungalows and park homes where the wall is sound and there are no fire-height restrictions. It is a good fit where eaves are shallow, because grey EPS can hit the target with less thickness. On buildings with a storey 11 metres or more above ground, or where the guidance asks for non-combustible materials, mineral wool is used instead.

EPS insulation in Finchley: questions
How long does EPS last on a wall?
The board itself doesn't degrade when protected by the render system. Service life depends on the render, sealants and detailing, typically 25–30 years or more with maintenance.
Will woodpeckers damage EPS?
It happens occasionally, especially near woodland. Damage is to the render and board surface and is repaired with a mesh patch and colour-matched finish.
White or grey EPS?
Grey graphite EPS insulates better per millimetre, so it is the pick where space is tight at the eaves or around windows. White EPS is slightly cheaper and works well where the extra thickness isn't a problem.
