Cornwall: walls, weather and approvals
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 Cornwall 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.
We bring brick slip samples to Cornwall surveys so you can compare them with neighbouring houses.

Approvals 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.
Are brick slips real brick?
They can be — cut or manufactured clay slips — or concrete and flexible polymer slips designed to look like brick. Clay slips are heavier and need systems rated for that weight.

Brick slip EWI in Cornwall: questions
Is a brick slip finish more expensive?
Yes — roughly £70–£120 per m² more than render, because of materials and slower installation.
Will brick slips match my neighbours' brick?
We source slips to get close in colour and texture and show samples beforehand, but an exact match to weathered brick isn't always possible.
Do brick slips fall off?
Not when installed to the system manufacturer's specification, with the right adhesive, fixings and pointing.
Do you cover all of Cornwall?
Yes. We survey and quote brick slip finishes across Cornwall, including Redruth, Falmouth, St Austell, Truro, Camborne.
Do I need planning permission in England?
For houses, external wall insulation and render are often permitted development where the finish looks similar to the existing walls. We check your address before quoting.
