Homes and walls in Chislehurst
As well as Chislehurst itself, we quote in Eltham, Welling and Bexley. 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 Chislehurst, we programme the work around opening hours so the building can keep trading.

Planning and building control in England
Before quoting in Chislehurst, 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.
How is the work programmed?
Work is split by elevation so entrances and fire exits stay usable. For schools, noisy and access-heavy stages are planned around holidays where possible. Health and safety duties under CDM 2015 are agreed at the start, including who acts as principal contractor.

Do you handle the planning application?

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 provide a maintenance plan?
Yes — the handover includes the system documents and recommended inspection and cleaning intervals.
Do you cover Chislehurst?
Yes — we survey and quote commercial external wall insulation in Chislehurst (BR7) and nearby Eltham, Welling and Bexley, with a fixed written price before any work starts.
