Wall-mounted air conditioning in Belfast
In Northern Ireland, homes on oil or electric heating can look at air-to-air systems for efficient warmth. Where a home in Belfast faces the street, the outdoor unit usually goes at the rear, out of sight.
A single wall-mounted unit is often all a bedroom or sunny living room in Belfast needs. We cover Belfast and the rest of County Antrim, including Lisburn and Newtownabbey. Homes in BT1, BT2, BT3, BT7, BT9 and 3 more are all within our coverage.
Prices in Belfast
Our Northern Ireland guide price for wall-mounted air conditioning is £1,045–£2,695 per room, VAT included. It is a touch below the UK middle, as trade rates in Northern Ireland tend to be. What moves a quote in Belfast up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. On our Northern Ireland figures, the Popular option (quieter mid-range unit with Wi-Fi control and better seasonal efficiency for a living room) is about £1,445–£1,995.

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
Planning rules for outdoor units in Northern Ireland differ from Great Britain's, so we check your property with you and the council where needed.
The survey
A survey in Belfast 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. 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.
