Air conditioning for extensions and kitchen-diners in Fleet
The South East sees some of the UK's warmest summer days, and south-facing rooms and conservatories feel it first. An extension in Fleet with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon.
For a kitchen-diner in Fleet, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Fleet is about 36 miles from Southampton and falls within our Hampshire coverage. Coverage includes GU13, GU51 and GU52.
Prices in Fleet
Guide prices around Fleet 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 Fleet, 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
On a survey in Fleet 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. At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote.
