Multi-split air conditioning across County Durham
In a house in Durham with a usable loft, multi-split pipes can often run through it so the front stays clear. Multi-split is a good fit for Durham flats and maisonettes where only a balcony or one rear wall is available. Cold, windy North East winters favour a well-sized heat pump with an outdoor unit sheltered from the prevailing wind.

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 County Durham, 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
On a survey in County Durham 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. We book surveys in County Durham at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
