Air conditioning for extensions and kitchen-diners across Bedfordshire
In Luton, a side wall of a single-storey extension is usually the neatest place for the indoor unit. For a kitchen-diner in Luton, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Bright summers in the East of England mean solar gain through glass is usually the biggest load to design for.
Prices in Bedfordshire
In the East of England, our guide range for air conditioning for extensions and kitchen-diners is £1,595–£4,995 per space, including VAT. Prices here sit above the national middle, reflecting East of England labour rates and parking and access costs. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure. 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.
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. Surveys in Bedfordshire cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
