Garden room and home office air conditioning across Hampshire
For a garden room in Southampton, the outdoor unit usually sits on a small stand behind the building. Garden offices used every day in Southampton need cooling in summer and efficient heat in winter. Summers in the South East are among the warmest in the country, so cooling often comes first, with efficient winter heating as a bonus.

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
England's rules let most houses fit an outdoor unit without a planning application, as long as the size, number and MCS 020(a) noise conditions are met. Flats, listed buildings and roof-mounted units are treated differently.
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. A survey in Hampshire 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.
