Air conditioning for extensions and kitchen-diners in Chester
In Chester, a side wall of a single-storey extension is usually the neatest place for the indoor unit. In the North West, heating efficiency is often the main benefit, with summer cooling a welcome bonus.
For a kitchen-diner in Chester, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. We cover Chester as part of Cheshire, roughly 19 miles from Warrington. Homes in CH1 are all within our coverage.
Prices in Chester
For Chester, expect roughly £1,395 to £4,245 per space, VAT included, adjusted for typical North West England rates. That sits a little below the UK middle, reflecting typical North West England labour rates. The biggest variables are the pipe route, access for the outdoor unit and the state of the consumer unit, all of which the survey settles. As an example, the Large single option (one 5–7 kW unit for a large glazed space) would typically be £1,945–£2,695 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
For most houses in Chester, the outdoor unit is permitted development if it passes the MCS 020(a) noise check (37 dB(A) or less at the nearest neighbouring window) and stays within the size and number limits. We run that check on survey.
The survey
On a survey in Chester 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. A survey in Chester 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.
