Non-traditional and concrete house insulation in Littlehampton
From Littlehampton to Bognor Regis, we price non-traditional house insulation after a measured survey — no guesswork, and no work starts until the price is agreed in writing. Where one half of a pair in Littlehampton is insulated and the other isn't, we detail the boundary so the neighbour can join later.

What's included

What we look for in Littlehampton
We cover Littlehampton and nearby Bognor Regis, Worthing and Chichester. Littlehampton sits around 26 miles from Crawley. 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.
Exposure to wind-driven rain varies across West Sussex: 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.
Where a home in Littlehampton is system-built, the first job is confirming the construction type.

Permissions in England
Planning in Littlehampton 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.
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 Littlehampton: 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.
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.
Do you cover Littlehampton?
Yes — we survey and quote non-traditional house insulation in Littlehampton (BN17) and nearby Bognor Regis, Worthing and Chichester, with a fixed written price before any work starts.
