Multi-split air conditioning in Caerphilly
Wet South Wales winters make a heat pump's quiet, even heating and dehumidifying mode useful well beyond summer. Multi-split is a good fit for Caerphilly flats and maisonettes where only a balcony or one rear wall is available.
Twin and triple systems suit Caerphilly homes where bedrooms sit above the kitchen and one rear wall can take the outdoor unit. Caerphilly sits around 16 miles from Bridgend, inside our Mid Glamorgan area. That includes the CF83 postcode district.
Prices in Caerphilly
Guide prices around Caerphilly run from £2,245 to £7,145 for 2–4 rooms including VAT. It is a touch below the UK middle, as trade rates in South and Mid Wales tend to be. Longer or hidden pipe runs, high-level brackets and electrical upgrades are the usual reasons a quote lands at the top of the range. 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.
Twin
Two rooms on one outdoor unit, wall-mounted indoor units, standard routes.
Triple
Three rooms with mixed indoor styles and Wi-Fi control throughout.
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%.
Planning and permissions
Since 1 June 2026, Welsh permitted development rules for outdoor units closely match England's: up to 1.5 m³, two units on a detached home, one on other homes, and MCS 020a noise compliance. Listed buildings need consent, and conservation areas have extra restrictions on units facing a road.
The survey
On a survey in Caerphilly 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. A survey in Caerphilly 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.
