New build and renovation air conditioning in Castlereagh
For new Castlereagh extensions with flat roofs, the outdoor unit position is best agreed against the architect's drawings. Damp Northern Ireland winters make a heat pump's dehumidifying mode useful well beyond the summer.
Renovations in Castlereagh are the easiest jobs to make invisible, because the pipework goes in before the plaster. Castlereagh sits around 2 miles from Belfast, inside our County Antrim area. Homes in BT5 and BT6 are all within our coverage.
Prices in Castlereagh
For Castlereagh, expect roughly £365 to £795 per indoor position (first fix), VAT included, adjusted for typical Northern Ireland rates. It is a touch below the UK middle, as trade rates in Northern Ireland tend to be. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. As an example, the First and second fix option (complete install priced per room including units) would typically be £1,345–£2,695 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%.
Working with your builder
Because the pipework is built into the structure, coordination with your builder matters more than planning here; the outdoor unit follows the same rules as any other installation.

On a survey in Castlereagh the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows.
