Air conditioning for extensions and kitchen-diners in Washington
North East summers are cooler, so heat pump heating is often the main draw, with cooling for warm spells. For a kitchen-diner in Washington, we place the indoor unit clear of the hob and plan the outdoor unit at the rear.
An extension in Washington with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. We cover Washington as part of Tyne and Wear, roughly 6 miles from Newcastle upon Tyne. Coverage includes NE37 and NE38.
Prices in Washington

Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. As an example, the Large single option (one 5–7 kW unit for a large glazed space) would typically be £1,895–£2,595 here.

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
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 Washington 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 Washington cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
