Garden room and home office air conditioning in Kent

Garden room and home office air conditioning across Kent

For a garden room in Maidstone, the outdoor unit usually sits on a small stand behind the building. Garden offices used every day in Maidstone need cooling in summer and efficient heat in winter. In the South East, loft rooms and glazed extensions can climb well above the outside temperature on a sunny afternoon.

Prices in Kent

Guide prices around Kent run from £1,745 to £3,845 per system including VAT. That is above the UK middle, mainly because labour and access cost more in South East England. The biggest variables are the pipe route, access for the outdoor unit and the state of the consumer unit, all of which the survey settles. On our South East England figures, the Popular option (3.5 kW unit with Wi-Fi to warm up before you walk down the garden) is about £2,195–£2,995.

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

We book surveys in Kent at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. A survey in Kent 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.
