Multi-split air conditioning in Eastleigh
Multi-split is a good fit for Eastleigh flats and maisonettes where only a balcony or one rear wall is available. Hot spells reach the South East early, which makes spring the easiest time to arrange an installation.
Twin and triple systems suit Eastleigh homes where bedrooms sit above the kitchen and one rear wall can take the outdoor unit. Our Hampshire coverage takes in Eastleigh, about 5 miles from Southampton. Homes in SO50 are all within our coverage.

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