Air conditioning for extensions and kitchen-diners in Peterborough
Low rainfall and long summer days in the East of England make south-facing rooms the first to overheat. For a kitchen-diner in Peterborough, we place the indoor unit clear of the hob and plan the outdoor unit at the rear.
In Peterborough, a side wall of a single-storey extension is usually the neatest place for the indoor unit. We cover Peterborough and the rest of Cambridgeshire, including Cambridge and Wisbech. We cover PE1 and the streets around them.
Prices in Peterborough
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. The East of England is one of the dearer parts of the UK for trades, which shows in the range. Longer or hidden pipe runs, high-level brackets and electrical upgrades are the usual reasons a quote lands at the top of the range. As an example, the Large single option (one 5–7 kW unit for a large glazed space) would typically be £2,295–£3,195 here.
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
For most houses in Peterborough, the outdoor unit is permitted development if it passes the MCS 020(a) noise check (37 dB(A) or less at the nearest neighbouring window) and stays within the size and number limits. We run that check on survey.
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 Peterborough cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
