Ducted air conditioning in Oxford
The South East sees some of the UK's warmest summer days, and south-facing rooms and conservatories feel it first. In an older house in Oxford, the loft and any existing bulkheads decide whether a ducted layout will work.
Ducted systems suit Oxford loft conversions and new extensions where ceilings are being boarded anyway. We cover Oxford and the rest of Oxfordshire, including Banbury and Abingdon. Postcode districts we cover here include OX1.
Prices in Oxford
Our South East England guide price for ducted air conditioning is £6,645–£18,245 per system, VAT included. South East England is one of the dearer parts of the UK for trades, which shows in the range. Longer or hidden pipe runs, high-level brackets and electrical upgrades are the usual reasons a quote lands at the top of the range. On our South East England figures, the Zoned option (motorised dampers or two units for separate floors or room groups) is about £9,095–£13,345.

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
In England, most houses can have an outdoor unit under permitted development if it is no larger than 1.5 m³, meets the MCS 020(a) noise limit of 37 dB(A) at the nearest neighbour's window, and there are no more than two on a detached house or one on other houses. Listed buildings need consent.
The survey
We book surveys in Oxford at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote.
