What you get

- Steel-framed BISF houses need care around the upper-storey cladding
- Most system-built homes have thin, cold walls and no fillable cavity
Local considerations in Swindon
We cover Swindon and nearby Chippenham, Witney and Stroud. The South West has many stone and solid-walled cottages, exposed coastal properties and a share of post-war system-built houses, including types such as the Cornish Unit.
Exposure to wind-driven rain varies across Wiltshire: sheltered town streets fare better than walls on high ground or facing the prevailing weather, and the render, beads and cill details are chosen with that in mind.
For concrete houses in Swindon, we report any visible spalling or cracking before quoting the insulation, not after.

Planning and building control in England
For a house in Swindon, 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.
Insulating or re-rendering more than half of a wall's area brings in Part L of the Building Regulations, so building control is notified and the wall is upgraded to about 0.30 W/m²K where practical.
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 Swindon: questions
Can you insulate a Wimpey no-fines house?
Yes. No-fines houses have solid poured-concrete walls with no cavity, so EWI is the usual route. The survey checks the concrete condition first.
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.
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.
Do you cover Swindon?
Yes — we survey and quote non-traditional house insulation in Swindon (SN1) and nearby Chippenham, Witney and Stroud, with a fixed written price before any work starts.
