Homes and walls in Dorset
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 Dorset: 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.

Planning and building control in England
For houses, external wall insulation and render are often permitted development where the finish looks similar to the existing walls. Planning permission is usually needed in conservation areas, National Parks, National Landscapes, the Broads and World Heritage Sites (where cladding a house in stone, artificial stone, pebble dash, render, timber, plastic or tiles isn't permitted development), for flats and maisonettes, for commercial buildings, under an Article 4 direction, or where the look changes noticeably. Listed buildings need listed building consent.
Renovating more than half of a wall's area — insulating it, or stripping and re-rendering it — or more than a quarter of the building's whole external envelope brings in the energy requirements of Part L, so building control needs to be involved and the wall should reach about 0.30 W/m²K where that's technically, functionally and economically feasible.

Dorset: questions
Do you work across all of Dorset?
Yes — we survey and quote across Dorset, including Bournemouth, Poole, Weymouth, Christchurch, Dorchester, Bridport.
Do I need planning permission for external wall insulation in Dorset?
Before quoting in Dorset, 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.
Are there grants for wall insulation in England?
ECO4 runs until 31 December 2026 for eligible households, and some councils run Warm Homes: Local Grant schemes. The Warm Homes Plan sets out further grants and low-interest loans being introduced in phases.
