Air conditioning for extensions and kitchen-diners in Dolgellau
For a kitchen-diner in Dolgellau, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. North Wales has mild, damp weather for much of the year, so efficient heating and dehumidifying are big benefits.
An extension in Dolgellau with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Dolgellau sits around 35 miles from Bangor, Gwynedd, inside our Gwynedd area. Homes in LL40 are all within our coverage.

Guide prices show VAT at 20%. HMRC treats most fixed air conditioners and air-to-air heat pumps installed in homes as energy-saving materials, zero-rated until 31 March 2027 when we supply and fit them. If your installation qualifies, your quote shows 0% VAT and a lower price. Servicing, repairs, cleaning and controls are charged at 20%.
Planning and permissions
In Wales, outdoor units of up to 1.5 m³ that meet MCS 020a noise limits are usually permitted development on houses; listed buildings need consent, and in conservation areas a unit cannot go on a wall or roof facing a road.
