Air conditioning for extensions and kitchen-diners across the West Midlands
An extension in Birmingham with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. For a kitchen-diner in Birmingham, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Away from the coast, West Midlands summers can turn hot quickly, and bedrooms under the roof are the first to suffer.
Prices in the West Midlands
For the West Midlands, expect roughly £1,395 to £4,345 per space, VAT included, adjusted for typical West Midlands rates. That is close to the UK middle for this kind of work. 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. Typical Large single work (one 5–7 kW unit for a large glazed space) lands around £1,995–£2,795 in this area.
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
England's rules let most houses fit an outdoor unit without a planning application, as long as the size, number and MCS 020(a) noise conditions are met. Flats, listed buildings and roof-mounted units are treated differently.
The survey
We book surveys in the West Midlands at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. Surveys in the West Midlands cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
