Garden room and home office air conditioning in Southampton
Garden offices used every day in Southampton need cooling in summer and efficient heat in winter. Hot spells reach the South East early, which makes spring the easiest time to arrange an installation.
For a garden room in Southampton, the outdoor unit usually sits on a small stand behind the building. We cover Southampton and the rest of Hampshire, including Portsmouth and Basingstoke. That includes the SO15 postcode district.

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
In England, most houses can have an outdoor unit under permitted development if it is no larger than 1.5 m³, meets the MCS 020(a) noise limit of 37 dB(A) at the nearest neighbour's window, and there are no more than two on a detached house or one on other houses. Listed buildings need consent.
The survey
On a survey in Southampton the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows. Surveys in Southampton cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
