Ducted air conditioning across Hampshire
For a renovation in Southampton, the best time to plan ducted cooling is before the plasterers arrive. In an older house in Southampton, the loft and any existing bulkheads decide whether a ducted layout will work. Hot spells reach the South East early, which makes spring the easiest time to arrange an installation.
Prices in Hampshire
In South East England, our guide range for ducted air conditioning is £6,645–£18,245 per system, including VAT. That is above the UK middle, mainly because labour and access cost more in South East England. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure. For reference, the Zoned option in Hampshire (motorised dampers or two units for separate floors or room groups) usually comes to about £9,095–£13,345.

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 Hampshire, 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
Surveys in Hampshire cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. We book surveys in Hampshire at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
