Ducted air conditioning in Bicester
For a renovation in Bicester, the best time to plan ducted cooling is before the plasterers arrive. Summers in the South East are among the warmest in the country, so cooling often comes first, with efficient winter heating as a bonus.
Ducted systems suit Bicester loft conversions and new extensions where ceilings are being boarded anyway. Bicester is about 11 miles from Oxford and falls within our Oxfordshire coverage. Coverage includes OX6, OX25, OX26 and OX27.
Prices in Bicester
For Bicester, expect roughly £6,645 to £18,245 per system, VAT included, adjusted for typical South East England rates. That is above the UK middle, mainly because labour and access cost more in South East England. What moves a quote in Bicester up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. Typical Zoned work (motorised dampers or two units for separate floors or room groups) lands around £9,095–£13,345 in this area.

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 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.
