Conservatory air conditioning in Southampton
In Southampton, the indoor unit usually goes on the original house wall inside the conservatory. Summers in the South East are among the warmest in the country, so cooling often comes first, with efficient winter heating as a bonus.
Conservatories and orangeries in Southampton can swing from too hot in July to too cold in January. As well as Southampton itself, our Hampshire coverage takes in Portsmouth, Basingstoke and the towns around them. Coverage includes SO15.

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.

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.

We book surveys in Southampton at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote.
