Multi-split air conditioning across Gwynedd
Twin and triple systems suit Bangor homes where bedrooms sit above the kitchen and one rear wall can take the outdoor unit. Multi-split is a good fit for Bangor flats and maisonettes where only a balcony or one rear wall is available. In North Wales, an air-to-air system can be an efficient way to heat holiday homes and bungalows, with cooling as a bonus.
Prices in Gwynedd
For Gwynedd, expect roughly £2,295 to £7,295 for 2–4 rooms, VAT included, adjusted for typical North Wales rates. That sits a little below the UK middle, reflecting typical North Wales labour rates. What moves a quote in Gwynedd up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed.

Twin
Two rooms on one outdoor unit, wall-mounted indoor units, standard routes.

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
At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote. The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote.
