New build and renovation air conditioning in Southampton
Renovations in Southampton are the easiest jobs to make invisible, because the pipework goes in before the plaster. Hot spells reach the South East early, which makes spring the easiest time to arrange an installation.
For new Southampton extensions with flat roofs, the outdoor unit position is best agreed against the architect's drawings. We cover Southampton and the rest of Hampshire, including Portsmouth and Basingstoke. Coverage includes SO15.
Prices in Southampton
Our South East England guide price for air conditioning for new builds and renovations is £495–£1,095 per indoor position (first fix), VAT included. That is above the UK middle, mainly because labour and access cost more in South East England. What moves a quote in Southampton up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. Typical First and second fix work (complete install priced per room including units) lands around £1,745–£3,595 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%.
Working with your builder
Because the pipework is built into the structure, coordination with your builder matters more than planning here; the outdoor unit follows the same rules as any other installation.
The survey
We book surveys in Southampton at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. A survey in Southampton 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.
