Ducted air conditioning in Belfast
In Northern Ireland, cooling is mostly needed in conservatories and glazed rooms, while efficient heating benefits the whole home. In an older house in Belfast, the loft and any existing bulkheads decide whether a ducted layout will work.
Ducted systems suit Belfast loft conversions and new extensions where ceilings are being boarded anyway. As well as Belfast itself, our County Antrim coverage takes in Lisburn, Newtownabbey and the towns around them. Postcode districts we cover here include BT1, BT2, BT3, BT7, BT9 and 3 more.
Prices in Belfast
Ducted air conditioning in Belfast typically comes in at £4,995–£13,745 per system including VAT, based on Northern Ireland rates. Labour rates in Northern Ireland keep this slightly under the national middle. The biggest variables are the pipe route, access for the outdoor unit and the state of the consumer unit, all of which the survey settles. As an example, the Zoned option (motorised dampers or two units for separate floors or room groups) would typically be £6,845–£10,045 here.

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
Northern Ireland has its own planning rules for outdoor units, and conservation areas and listed buildings need particular care. We confirm the position for your property before installation.
