Air conditioning for extensions and kitchen-diners in Bicester
Summers in the South East are among the warmest in the country, so cooling often comes first, with efficient winter heating as a bonus. An extension in Bicester with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon.
For a kitchen-diner in Bicester, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. We cover Bicester as part of Oxfordshire, roughly 11 miles from Oxford. Postcode districts we cover here include OX6, OX25, OX26 and OX27.
Prices in Bicester
Guide prices around Bicester run from £1,745 to £5,445 per space including VAT. That is above the UK middle, mainly because labour and access cost more in South East England. The biggest variables are the pipe route, access for the outdoor unit and the state of the consumer unit, all of which the survey settles. As an example, the Large single option (one 5–7 kW unit for a large glazed space) would typically be £2,495–£3,495 here.
Single unit
One 3.5–5 kW unit for a medium extension.
Large single
One 5–7 kW unit for a large glazed space.
Twin units
Two indoor units on a multi-split for long or L-shaped spaces.
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
For most houses in Bicester, the outdoor unit is permitted development if it passes the MCS 020(a) noise check (37 dB(A) or less at the nearest neighbouring window) and stays within the size and number limits. We run that check on survey.
The survey
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. Surveys in Bicester cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
