Air conditioning for extensions and kitchen-diners in Shirley
For a kitchen-diner in Shirley, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Hot spells in the West Midlands are shorter but intense, especially in loft rooms and rooms with big windows.
An extension in Shirley with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Shirley is about 6 miles from Birmingham and falls within our West Midlands coverage. Coverage includes B90.
Prices in Shirley
Budget around £1,395–£4,345 per space including VAT for air conditioning for extensions and kitchen-diners in and around Shirley. 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. As an example, the Large single option (one 5–7 kW unit for a large glazed space) would typically be £1,995–£2,795 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
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
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. A survey in Shirley 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.
