Replacing windows in the South West

In the South West the houses are as varied as the weather: granite and slate in Cornwall and Devon, Bath stone and Georgian terraces around Bristol and Bath, and cob cottages with deep, uneven reveals. Openings that were never quite square need a careful survey before anything is ordered. Exposed coastal sites and national park rules can both shape what you are allowed to fit.

Much of the South West is solid-walled: granite and slate in Cornwall, stone and cob in Devon, and Bath stone in the city and along the Cotswold edge. Openings are often deep and not quite square, so windows have to be measured on site. Bristol adds large Victorian terraced streets with bays and sashes.

Planning and building rules in the South West

Dartmoor, Exmoor and several National Landscapes cover much of the region, Bath is a World Heritage Site, and Cornwall and Devon hold many listed buildings. In those places the council will often accept only like-for-like timber windows, so check before you price anything in uPVC.

Rules change, so check the current position with your council and the Planning Portal guide to doors and windows: read the official guidance.

How the weather affects new windows in the South West

Mild, wet and windy, with some of England's heaviest rain on Dartmoor and Exmoor. Houses on the Cornish and north Devon coasts face driving rain and salt, so draught seals, drainage channels and corrosion-resistant hardware matter more than they would inland.
