Home air conditioning in Southampton
The South East sees some of the UK's warmest summer days, and south-facing rooms and conservatories feel it first. Southampton is one of the main towns we cover in Hampshire, alongside Portsmouth and Basingstoke. Postcode districts we cover here include SO15.
Rooms and systems
In an older house in Southampton, the loft and any existing bulkheads decide whether a ducted layout will work. For bedrooms in Southampton, we place the outdoor unit at the back of the house, away from neighbours' windows. Drip and drain faults are a common reason a system in Southampton stops working properly in the first hot week. Old storage heaters in Southampton homes are removed and recycled as part of the replacement.
If heating matters as much as cooling, an air-to-air heat pump sized for winter can replace old electric heaters room by room, and still cool in summer. Existing systems need care too: an annual service, an occasional deep clean and prompt repairs keep them efficient and quiet.
Guide prices in Southampton
On our South East England figures, a wall-mounted system is typically £1,395–£3,595 per room, a garden room system £1,745–£3,845 per system, and air conditioning in a flat £1,645–£7,245 per flat, all including VAT. Installations are fixed in writing after a free survey; visits are priced before we come.
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. For flats in Southampton, the lease and the freeholder's consent come first. Planning rules for blocks of flats are stricter than for houses, and we check them before quoting.
Southampton is in the Boiler Upgrade Scheme area, so eligible homes replacing oil, gas, LPG or electric heating may be able to get £2,500 off an air-to-air heat pump, as long as no fossil-fuel boiler stays in use. An MCS-certified installer must claim it; we confirm eligibility, and which installer applies, before you commit.
