Air conditioning for period and listed homes in Carshalton
If your Carshalton home is listed or in a conservation area, consent comes first and we provide what the council needs to see. The urban heat island effect means London bedrooms can stay uncomfortably warm on summer nights.
If your home in Carshalton is Victorian, Edwardian or older, a console or concealed system often works better than a high wall unit. Carshalton sits around 9 miles from central London, inside our London area. That includes the SM5 postcode district.
Prices in Carshalton
Budget around £2,195–£10,495 per home, one room upwards including VAT for air conditioning for period and listed homes in and around Carshalton. London is one of the dearer parts of the UK for trades, which shows in the range. 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 London figures, the Concealed option (ducted unit from a loft or void serving one or two rooms) is about £4,545–£7,195.
Console
Low-level console in place of a radiator, rear outdoor unit.

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%.
Listed building consent
For a listed property in Carshalton, consent comes first: the council decides on the outdoor unit position, the pipe routes and any change to historic fabric. Conservation areas add their own limits on units facing a road. 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
On a survey in Carshalton the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows. We book surveys in Carshalton at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
