Multi-split air conditioning across County Londonderry
In a house in Derry/Londonderry with a usable loft, multi-split pipes can often run through it so the front stays clear. Twin and triple systems suit Derry/Londonderry homes where bedrooms sit above the kitchen and one rear wall can take the outdoor unit. Damp Northern Ireland winters make a heat pump's dehumidifying mode useful well beyond the summer.
Prices in County Londonderry
For County Londonderry, expect roughly £2,245 to £7,145 for 2–4 rooms, VAT included, adjusted for typical Northern Ireland rates. That sits a little below the UK middle, reflecting typical Northern Ireland labour rates. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure. As an example, the Triple option (three rooms with mixed indoor styles and Wi-Fi control throughout) would typically be £3,095–£4,995 here.

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

Quad
Four or five rooms, longer concealed runs or a ducted unit in a loft void.
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%.
