What affects air source heat pump costs in Wales

Tradespeople in Wales typically charge £155 to £215 a day, which is 6% below the UK average and the single biggest reason prices here differ from the national figure.

Wales has one of the highest proportions of solid-wall, pre-1919 housing anywhere in the UK. The valleys are lined with stone terraces built for the coal and steel industries, roofed in Welsh slate and stepped down steep hillsides, which makes access and scaffolding a larger share of the bill than it would be on level ground. Cardiff and Newport add Victorian and interwar suburbs on more conventional lines.

Wet and exposed. Snowdonia is among the wettest ground in the UK, with parts of the uplands recording well over 2,000mm a year against a UK average nearer 1,150mm. Driving rain on west-facing solid walls is the single biggest weathering problem in the Welsh stock, and it is why breathable repair and correct pointing matter more here than in the dry east of England.

Planning and building regulations in Wales

Building regulations in Wales are set by the Welsh Government and have diverged from England, particularly on energy efficiency, so guidance written for England does not always apply. Eryri (Snowdonia), Bannau Brycheiniog (the Brecon Beacons) and Pembrokeshire Coast are National Parks. Welsh slate roofs in conservation areas usually have to be repaired in slate.
