Chichester: walls, weather and approvals
As well as Chichester itself, we quote in Bognor Regis, Havant and Littlehampton. Chichester sits around 32 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 one half of a pair in Chichester is insulated and the other isn't, we detail the boundary so the neighbour can join later.

Permissions in England
For a house in Chichester, 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.
If the work covers more than half of a wall, or a quarter of the building's whole envelope, it counts as renovating a thermal element, with a target of about 0.30 W/m²K where feasible.
What does the work involve?
After checking the wall condition, any spalling concrete or corroded steel is reported before boards go on. Fixings are chosen for the substrate — concrete, steel-framed panels or mixed constructions — and the system is detailed around eaves, cills and the junction with neighbouring properties, which may not be insulated.

Non-traditional houses in Chichester: 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 Chichester?
Yes — we survey and quote non-traditional house insulation in Chichester (PO19) and nearby Bognor Regis, Havant and Littlehampton, with a fixed written price before any work starts.
