Homes and walls in Devon
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.
Parts of Devon fall in the higher wind-driven rain exposure bands, especially coastal and upland sites, so render specification, movement joints and detailing at cills, verges and the base of the wall matter more than usual.

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.

Devon: questions
Do you work across all of Devon?
Yes — we survey and quote across Devon, including Plymouth, Exeter, Torquay, Paignton, Newton Abbot, Exmouth.
Do I need planning permission for external wall insulation in Devon?
Before quoting in Devon, 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.
