Ducted air conditioning across Gwynedd
Ducted systems suit Bangor loft conversions and new extensions where ceilings are being boarded anyway. For a renovation in Bangor, the best time to plan ducted cooling is before the plasterers arrive. North Wales has mild, damp weather for much of the year, so efficient heating and dehumidifying are big benefits.
Prices in Gwynedd
Budget around £5,095–£14,045 per system including VAT for ducted air conditioning in and around Gwynedd. It is a touch below the UK middle, as trade rates in North Wales tend to be. Longer or hidden pipe runs, high-level brackets and electrical upgrades are the usual reasons a quote lands at the top of the range. For reference, the Zoned option in Gwynedd (motorised dampers or two units for separate floors or room groups) usually comes to about £6,995–£10,295.

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.
The survey
Surveys in Gwynedd cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. A survey in Gwynedd usually takes one to two hours. We measure the rooms, check the walls and the consumer unit, agree the outdoor unit position with you and photograph the pipe routes.
