Multi-split air conditioning in Stockton-on-Tees

Twin and triple systems suit Stockton-on-Tees homes where bedrooms sit above the kitchen and one rear wall can take the outdoor unit. Stockton-on-Tees is about 18 miles from Durham and falls within our County Durham coverage. Postcode districts we cover here include TS19.

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
Since 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.
