Air conditioning for extensions and kitchen-diners in Hailsham
The South East sees some of the UK's warmest summer days, and south-facing rooms and conservatories feel it first. For a kitchen-diner in Hailsham, we place the indoor unit clear of the hob and plan the outdoor unit at the rear.
In Hailsham, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Hailsham is about 17 miles from Brighton and falls within our East Sussex coverage. That includes the BN27 postcode district.

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
