Air conditioning for extensions and kitchen-diners in Darlington
Cooler North East summers mean cooling is mostly needed in lofts, conservatories and rooms with large windows. In Darlington, a side wall of a single-storey extension is usually the neatest place for the indoor unit.
For a kitchen-diner in Darlington, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Darlington lies roughly 17 miles from Durham, and we cover it as part of County Durham. Coverage includes DL3.

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

On a survey in Darlington the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows.
