Local considerations in Buckinghamshire
Homes across the South East range from inter-war semis and post-war estates, which are mostly cavity-walled, to older solid-walled cottages and Victorian town terraces.
Much of Buckinghamshire 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 concrete houses in Buckinghamshire, we report any visible spalling or cracking before quoting the insulation, not after.

England: planning and regulations
For houses, external wall insulation and render are often permitted development where the finish looks similar to the existing walls. Planning permission is usually needed in conservation areas, National Parks, National Landscapes, the Broads and World Heritage Sites (where cladding a house in stone, artificial stone, pebble dash, render, timber, plastic or tiles isn't permitted development), for flats and maisonettes, for commercial buildings, under an Article 4 direction, or where the look changes noticeably. Listed buildings need listed building consent.
Renovating more than half of a wall's area — insulating it, or stripping and re-rendering it — or more than a quarter of the building's whole external envelope brings in the energy requirements of Part L, so building control needs to be involved and the wall should reach about 0.30 W/m²K where that's technically, functionally and economically feasible.
How do I know if my house is non-traditional?
Clues include concrete panels or posts visible at corners, a smooth concrete or rendered finish on houses of a 1940s–1960s estate, steel sheeting on the upper storey, or a mortgage valuation that mentioned the construction type. Common types include Wimpey no-fines (poured concrete), Airey and Cornish Unit (precast reinforced concrete), Reema, Orlit and BISF (steel frame). We identify the type during the survey.

Non-traditional houses in Buckinghamshire: questions
What if my neighbour isn't insulating?
We finish the system neatly at the boundary with a closing detail so the neighbouring house isn't affected and can be joined later.
Will EWI make my house mortgageable?
It can make a house more attractive and better insulated, but it does not replace a certified structural repair where a lender requires one. Ask your lender before relying on it.
Can you put EWI on a BISF house?
Yes, with care. The steel frame and upper-storey cladding need a system and fixing method designed for that construction, and the condition of the frame should be understood first.
Do you cover all of Buckinghamshire?
Yes. We survey and quote non-traditional house insulation across Buckinghamshire, including Milton Keynes, High Wycombe, Aylesbury, Bletchley, Amersham.
Do I need planning permission in England?
For houses, external wall insulation and render are often permitted development where the finish looks similar to the existing walls. We check your address before quoting.
