Conservatory air conditioning across Kent
If your conservatory in Maidstone faces south, that is where overheating is worst. Conservatories and orangeries in Maidstone can swing from too hot in July to too cold in January. Hot spells reach the South East early, which makes spring the easiest time to arrange an installation.
Prices in Kent
Guide prices around Kent run from £1,745 to £4,195 per system including VAT. That is above the UK middle, mainly because labour and access cost more in South East England. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure. Typical Popular work (5 kW unit with Wi-Fi for a medium conservatory or orangery) lands around £2,245–£3,145 in this area.
Essential
3.5 kW unit for a small lean-to or Edwardian conservatory.
Popular
5 kW unit with Wi-Fi for a medium conservatory or orangery.
Premium
7 kW or console-plus-wall setup for large glazed rooms.
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 Kent 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.
