Air conditioning for extensions and kitchen-diners across Surrey
For a kitchen-diner in Woking, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. In Woking, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Summers in the South East are among the warmest in the country, so cooling often comes first, with efficient winter heating as a bonus.
Prices in Surrey
For Surrey, expect roughly £1,745 to £5,445 per space, VAT included, adjusted for typical South East England rates. Prices here sit above the national middle, reflecting South East England labour rates and parking and access costs. What moves a quote in Surrey up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. 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
England's rules let most houses fit an outdoor unit without a planning application, as long as the size, number and MCS 020(a) noise conditions are met. Flats, listed buildings and roof-mounted units are treated differently.
The survey
On a survey in Surrey 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. We book surveys in Surrey at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
