Garden room and home office air conditioning in Surrey

Garden room and home office air conditioning across Surrey

Garden offices used every day in Woking need cooling in summer and efficient heat in winter. We check the armoured supply cable on every Woking garden room before quoting. Summers in the South East are among the warmest in the country, so cooling often comes first, with efficient winter heating as a bonus.

Prices in Surrey

Garden room and home office air conditioning in Surrey typically comes in at £1,745–£3,845 per system including VAT, based on South East England rates. 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

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.

The survey

Surveys in Surrey cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote.
