Air conditioning for extensions and kitchen-diners in Holloway
In London, heat soaks into brick and concrete during the day and comes back out at night, which is when it is hardest to sleep. An extension in Holloway with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon.
For a kitchen-diner in Holloway, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. We cover Holloway as part of London, roughly 4 miles from central London. Homes in N7 are all within our coverage.
Prices in Holloway
Guide prices around Holloway run from £1,895 to £5,845 per space including VAT. That is above the UK middle, mainly because labour and access cost more in London. Longer or hidden pipe runs, high-level brackets and electrical upgrades are the usual reasons a quote lands at the top of the range. For reference, the Large single option in Holloway (one 5–7 kW unit for a large glazed space) usually comes to about £2,695–£3,745.
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
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.
The survey
A survey in Holloway 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. The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote.
