Air conditioning for extensions and kitchen-diners in Leeds
Cold Yorkshire winters mean sizing for heating first, then checking the summer cooling load. For a kitchen-diner in Leeds, we place the indoor unit clear of the hob and plan the outdoor unit at the rear.
In Leeds, a side wall of a single-storey extension is usually the neatest place for the indoor unit. As well as Leeds itself, our West Yorkshire coverage takes in Bradford, Huddersfield and the towns around them. Postcode districts we cover here include LS1, LS2, LS3, LS4, LS6 and LS13.
Prices in Leeds
For Leeds, expect roughly £1,395 to £4,245 per space, VAT included, adjusted for typical Yorkshire and the Humber rates. It is a touch below the UK middle, as trade rates in Yorkshire and the Humber tend to be. What moves a quote in Leeds up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. For reference, the Large single option in Leeds (one 5–7 kW unit for a large glazed space) usually comes to about £1,945–£2,695.
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
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 Leeds 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. 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.
