Wall-mounted air conditioning across Hampshire
In a semi or terrace in Southampton, the indoor unit often goes on a back bedroom wall with the outdoor unit on a bracket below. A single wall-mounted unit is often all a bedroom or sunny living room in Southampton needs. In the South East, loft rooms and glazed extensions can climb well above the outside temperature on a sunny afternoon.
Prices in Hampshire
Budget around £1,395–£3,595 per room including VAT for wall-mounted air conditioning in and around Hampshire. Prices here sit above the national middle, reflecting South East England labour rates and parking and access costs. Longer or hidden pipe runs, high-level brackets and electrical upgrades are the usual reasons a quote lands at the top of the range. Typical Popular work (quieter mid-range unit with Wi-Fi control and better seasonal efficiency for a living room) lands around £1,895–£2,595 in this area.

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 Hampshire 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 Hampshire at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
