Conservatory air conditioning across Gwynedd
Conservatories and orangeries in Bangor can swing from too hot in July to too cold in January. If your conservatory in Bangor faces south, that is where overheating is worst. North Wales has mild, damp weather for much of the year, so efficient heating and dehumidifying are big benefits.

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.
