Air conditioning for extensions and kitchen-diners in Billericay
For a kitchen-diner in Billericay, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Long sunny spells in the East of England put conservatories and top-floor rooms under real pressure.
In Billericay, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Billericay lies roughly 14 miles from Southend-on-Sea, and we cover it as part of Essex. Coverage includes CM11.
Prices in Billericay
Our East of England guide price for air conditioning for extensions and kitchen-diners is £1,595–£4,995 per space, VAT included. That is above the UK middle, mainly because labour and access cost more in the East of England. Longer or hidden pipe runs, high-level brackets and electrical upgrades are the usual reasons a quote lands at the top of the range. 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.

We book surveys in Billericay at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. Surveys in Billericay cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
