Air conditioning installers in Southampton
38 vetted installers covering Southampton
Southampton is 8th of 91 towns and cities in our UK Air Con Index, with an average summer high of 22.8°C across 2016 to 2025, and around 41% of homes in the city are flats. If you're weighing up which aircon unit to buy and who should fit it, the installers below cover Southampton, and the postcode search will find firms for Eastleigh, Chandler's Ford, Hedge End, and Totton.
Choosing an aircon unit for a Southampton home
For most houses, including the Victorian and Edwardian terraces of Portswood, Shirley, and Freemantle, the usual answer is a wall-mounted split: a slim indoor unit linked by refrigerant pipework to an outdoor unit on the back wall or the ground. Only an F-Gas certified engineer can connect that pipework, so a split is never a DIY job. Size matters more than brand, and our guide to what size air conditioning you need shows how to work it out room by room.
Flats are trickier, because the outdoor unit normally needs the freeholder's consent; our guide to air conditioning for flats covers the alternatives, including through-wall units with no outdoor box and portables for renters.
Planning and grants
Southampton City Council handles planning inside the city, while Eastleigh, Chandler's Ford, and Hedge End fall under Eastleigh Borough Council and Totton under New Forest District Council. In England a reverse-cycle unit that heats as well as cools is often permitted development, but a cooling-only unit generally needs planning permission, so check with your council before booking. If a reverse-cycle system will heat your whole home and replace fossil-fuel or electric heating, an MCS certified installer may be able to claim the £2,500 Boiler Upgrade Scheme grant on your behalf.

There's no Southampton price list, since every job is different, so treat these as UK ranges. A wall-mounted split system for one room typically costs around £1,500 to £2,500 supplied and fitted, while a portable aircon unit costs roughly £300 to £650 and simply plugs in. Quotes from the installers above will vary with the room size, the pipe run to the outdoor unit, and whether a new electrical circuit is needed, so get two or three in writing before you decide.
Frequently asked questions
Which aircon unit is best for a Southampton home?
For most houses, a wall-mounted split system is the best all-round choice: it's quiet, efficient, and a reverse-cycle model heats in winter as well. Flats that can't have an outdoor unit may suit a through-wall unit with no outdoor box, and renters often start with a portable. The right size depends on the room, so ask the installer to calculate it rather than guessing.
How much does an aircon unit cost to fit in Southampton?
Across the UK, a single-room wall-mounted split typically costs around £1,500 to £2,500 supplied and fitted, and a portable unit roughly £300 to £650 with no installation. A Southampton quote depends on the same things as anywhere else, mainly the size of the room, the pipe run, and whether a new electrical circuit is needed, so compare written quotes from two or three installers.
Do I need planning permission for air conditioning in Southampton?
A reverse-cycle unit that heats as well as cools can usually be installed under permitted development in England, while a cooling-only unit generally needs planning permission. Flats, listed buildings, and conservation areas face tighter rules. Check with Southampton City Council before work starts, or with Eastleigh Borough Council or New Forest District Council if you live outside the city.
How do I find an accredited air conditioning installer in Southampton?
Anyone fitting a split system must hold F-Gas certification, and you can check the company on the REFCOM register before you sign. If you want the system to replace fossil-fuel or electric heating and qualify for the £2,500 Boiler Upgrade Scheme grant, the installer must also be MCS certified. Ask for a written quote naming the exact unit and what's included.
Does an aircon unit need servicing?
A split system should be serviced by an F-Gas certified engineer about once a year, with the filters cleaned by you in between. A service keeps the unit running efficiently and picks up problems, such as a blocked condensate drain, before they cause damage. Ask your installer whether the first service is included and what it costs after that.
