Homes and walls in Winchester
We cover Winchester and nearby Eastleigh, Southampton and Totton. It's roughly 12 miles from Winchester to Southampton, the largest town in Hampshire.
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 Hampshire: 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.

Approvals in England
For a house in Winchester, 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.

Winchester: questions
Do you cover Winchester?
Yes — we survey and quote in Winchester (SO23) and nearby Eastleigh, Southampton and Totton.
How much does external wall insulation cost in Winchester?
Our guide is £105–£170 per m² depending on the system, plus scaffolding — roughly £10,200–£17,700 for a typical three-bed semi with EPS and silicone render. Installing insulation in a home is zero-rated for VAT until 31 March 2027, so that's the total. A free survey fixes the price.
Do I need planning permission in Winchester?
Before quoting in Winchester, we check whether the property is in a conservation area, under an Article 4 direction or listed, because that decides whether changing the outside needs planning permission.
Is VAT charged on wall insulation?
Installing wall insulation in homes is zero-rated until 31 March 2027, then 5%, so our insulation prices are totals. Render-only work and repairs carry VAT at 20%, and our prices for them include it.
