Air conditioning for extensions and kitchen-diners in Hanworth
Many London homes are flats or tall terraces, where heat rises to the top floor and the bedrooms bear the brunt of a hot spell. An extension in Hanworth with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon.
For a kitchen-diner in Hanworth, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. We cover Hanworth as part of London, roughly 12 miles from central London. We cover TW13 and the streets around them.
Prices in Hanworth
Guide prices around Hanworth run from £1,895 to £5,845 per space including VAT. London is one of the dearer parts of the UK for trades, which shows in the range. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure. As an example, the Large single option (one 5–7 kW unit for a large glazed space) would typically be £2,695–£3,745 here.

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
In England, most houses can have an outdoor unit under permitted development if it is no larger than 1.5 m³, meets the MCS 020(a) noise limit of 37 dB(A) at the nearest neighbour's window, and there are no more than two on a detached house or one on other houses. Listed buildings need consent.

We book surveys in Hanworth at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
