Air conditioning for extensions and kitchen-diners across Suffolk
For a kitchen-diner in Ipswich, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. An extension in Ipswich with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Low rainfall and long summer days in the East of England make south-facing rooms the first to overheat.
Prices in Suffolk
Air conditioning for extensions and kitchen-diners in Suffolk typically comes in at £1,595–£4,995 per space including VAT, based on East of England rates. Prices here sit above the national middle, reflecting East of England labour rates and parking and access costs. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. On our East of England figures, the Large single option (one 5–7 kW unit for a large glazed space) is about £2,295–£3,195.

One 3.5–5 kW unit for a medium extension.

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. 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.
