Replacing windows in Wales
Wales shares most of its housing types with England, from slate-roofed valley terraces to seaside villas and farmhouses, but it has its own building regulations and its own heritage body for historic buildings. Ask any installer to confirm which rules apply to your address and how they certify the work. In rural and upland areas fitters travel far, so book the survey early.
Wales has a large share of solid-walled, pre-1919 housing: slate-roofed stone terraces line the valleys, with Victorian and interwar suburbs in Cardiff and Newport. Steep valley streets can make access harder for fitters, and that can show in the price.
Planning and building rules in Wales
Building regulations in Wales are set by the Welsh Government and have diverged from England's, so ask any fitter which rules apply to your address. Eryri, Bannau Brycheiniog and the Pembrokeshire Coast are National Parks, and Cadw protects listed buildings.
Rules change, so check the current position with your council and the Welsh Government building regulations guidance: read the official guidance.
How the weather affects new windows in Wales
Wet and exposed, with the uplands of Eryri (Snowdonia) among the wettest ground in the UK. Rain driven onto west-facing walls tests every seal, and coastal homes in Pembrokeshire and on the north coast add salt and wind.
