Air conditioning for extensions and kitchen-diners across Staffordshire
For a kitchen-diner in Stoke-on-Trent, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. An extension in Stoke-on-Trent with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. In the West Midlands, sizing for winter heating first and then checking summer cooling usually gives the best all-year system.
Prices in Staffordshire
Our West Midlands guide price for air conditioning for extensions and kitchen-diners is £1,395–£4,345 per space, VAT included. That is broadly in line with national guide prices. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs.

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
At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote. 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.
