Homes and walls in Brighton
We cover Brighton and nearby Hove, Portslade and Burgess Hill. 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 East 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.
On solid-walled houses in Brighton, the gable or the most weather-exposed wall is often the place to start.

England: planning and regulations
Before quoting in Brighton, 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.
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.
External or internal — which is better?
External insulation keeps the wall warm, reduces cold bridging at floors and party walls, renews the outside, and doesn't shrink rooms — but it changes the look and needs scaffolding. Internal insulation keeps the façade unchanged and can be done room by room, but loses 50–100mm of floor space per wall and needs careful detailing to avoid condensation at joists and corners.

Solid wall insulation in Brighton: questions
Can I do one wall at a time?
Yes. Many owners start with the coldest or most exposed elevation, often a gable end.
Does solid wall insulation cause condensation?
It can if detailed poorly, particularly internally. A condensation risk check for the proposed build-up and careful detailing at joists, reveals and corners avoid it.
Is solid wall insulation worth it?
For many solid-walled homes it's one of the biggest single improvements to comfort, because the walls are often the largest heat-loss area. Savings depend on the home and heating, so we don't promise a figure.
