Conservatory air conditioning in Carshalton

Conservatory air conditioning in Carshalton

Conservatories and orangeries in Carshalton can swing from too hot in July to too cold in January. In London, heat soaks into brick and concrete during the day and comes back out at night, which is when it is hardest to sleep.

In Carshalton, the indoor unit usually goes on the original house wall inside the conservatory. Carshalton lies roughly 9 miles from central London, and we cover it as part of London. Postcode districts we cover here include SM5.

For Carshalton, expect roughly £1,895 to £4,545 per system, VAT included, adjusted for typical London rates. Prices here sit above the national middle, reflecting London labour rates and parking and access costs. What moves a quote in Carshalton up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed.

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

A survey in Carshalton 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. 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.
