Conservatory air conditioning in Richmond
In Richmond, the indoor unit usually goes on the original house wall inside the conservatory. The urban heat island effect means London bedrooms can stay uncomfortably warm on summer nights.
If your conservatory in Richmond faces south, that is where overheating is worst. Richmond sits around 8 miles from central London, inside our London area. That includes the TW9 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.

We book surveys in Richmond at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote.
