Air conditioning for extensions and kitchen-diners in Cheshunt
The East of England is one of the sunniest and driest parts of the UK, which makes glazed rooms and lofts hard to keep cool. In Cheshunt, a side wall of a single-storey extension is usually the neatest place for the indoor unit.
For a kitchen-diner in Cheshunt, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Cheshunt is about 16 miles from Watford and falls within our Hertfordshire coverage. Coverage includes EN8.
Prices in Cheshunt
Our East of England guide price for air conditioning for extensions and kitchen-diners is £1,595–£4,995 per space, VAT included.

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
England's rules let most houses fit an outdoor unit without a planning application, as long as the size, number and MCS 020(a) noise conditions are met. Flats, listed buildings and roof-mounted units are treated differently.
The survey
A survey in Cheshunt usually takes one to two hours. We measure the rooms, check the walls and the consumer unit, agree the outdoor unit position with you and photograph the pipe routes. Surveys in Cheshunt cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
