Air conditioning for extensions and kitchen-diners in Fareham
In Fareham, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Hot spells reach the South East early, which makes spring the easiest time to arrange an installation.
An extension in Fareham with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Fareham sits around 10 miles from Southampton, inside our Hampshire area. Postcode districts we cover here include PO16.
Prices in Fareham
Guide prices around Fareham 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. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. 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 Fareham, 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
A survey in Fareham 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. Surveys in Fareham cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
