Wall-mounted air conditioning in Eastleigh
A single wall-mounted unit is often all a bedroom or sunny living room in Eastleigh needs. Hot spells reach the South East early, which makes spring the easiest time to arrange an installation.
Where a home in Eastleigh faces the street, the outdoor unit usually goes at the rear, out of sight. Eastleigh lies roughly 5 miles from Southampton, and we cover it as part of Hampshire. That includes the SO50 postcode district.
Prices in Eastleigh
Guide prices around Eastleigh run from £1,395 to £3,595 per room including VAT. South East England is one of the dearer parts of the UK for trades, which shows in the range. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure. As an example, the Popular option (quieter mid-range unit with Wi-Fi control and better seasonal efficiency for a living room) would typically be £1,895–£2,595 here.

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 Eastleigh, 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
The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote. On a survey in Eastleigh 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.
