Air conditioning for extensions and kitchen-diners in Leytonstone
For a kitchen-diner in Leytonstone, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. London's dense streets hold heat overnight, so top-floor flats and loft rooms often stay warm long after sunset.
An extension in Leytonstone with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Our London coverage takes in Leytonstone, about 7 miles from central London. Coverage includes E11.
Prices in Leytonstone
For Leytonstone, expect roughly £1,895 to £5,845 per space, VAT included, adjusted for typical London rates. That is above the UK middle, mainly because labour and access cost more in London. What moves a quote in Leytonstone 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 £2,695–£3,745 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.

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
Since 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.
The survey
On a survey in Leytonstone 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 Leytonstone at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
