Heston: walls, weather and approvals
As well as Heston itself, we quote in Hounslow, Isleworth and Southall. 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.
If your home in Heston is in a conservation area, we check the council's position on render before suggesting wood fibre EWI.

England: planning and regulations
Planning in Heston 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.
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.
What about listed buildings and conservation areas?
EWI on a listed building needs listed building consent and is often refused where the outside appearance matters. In conservation areas, rendering or cladding a house normally needs planning permission. Wood fibre and lime are more likely to be acceptable than foam and acrylic, but the council decides. We check before quoting.

Wood fibre EWI in Heston: questions
Is wood fibre worth the extra cost?
On older solid walls the main benefit is moisture safety rather than raw U-value. If the wall needs to breathe, the cheaper option can cost more later.
Does wood fibre need a lime render?
It needs the render specified by the system manufacturer, which is usually lime or mineral based.
Is wood fibre insulation fireproof?
No — it's a timber product. It chars rather than flaming readily, but it is combustible, so it's used on low-rise buildings within a tested system and never where non-combustible materials are required.
