Air conditioning for extensions and kitchen-diners in Swaffham
In Swaffham, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Long sunny spells in the East of England put conservatories and top-floor rooms under real pressure.
For a kitchen-diner in Swaffham, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. We cover Swaffham as part of Norfolk, roughly 26 miles from Norwich. Coverage includes PE37.
Prices in Swaffham
Guide prices around Swaffham run from £1,595 to £4,995 per space including VAT. That is above the UK middle, mainly because labour and access cost more in the East of England. What moves a quote in Swaffham up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. 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.
Single unit
One 3.5–5 kW unit for a medium extension.
Large single
One 5–7 kW unit for a large glazed space.

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
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. Surveys in Swaffham cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
