Air conditioning for period and listed homes in New Malden
If your home in New Malden is Victorian, Edwardian or older, a console or concealed system often works better than a high wall unit. London's dense streets hold heat overnight, so top-floor flats and loft rooms often stay warm long after sunset.
For period homes in New Malden, we look at consoles in place of radiators and ducted units from the loft before anything else. New Malden lies roughly 9 miles from central London, and we cover it as part of London. Coverage includes KT3.
Prices in New Malden
Our London guide price for air conditioning for period and listed homes is £2,195–£10,495 per home, one room upwards, VAT included. That is above the UK middle, mainly because labour and access cost more in London. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. As an example, the Concealed option (ducted unit from a loft or void serving one or two rooms) would typically be £4,545–£7,195 here.
Console
Low-level console in place of a radiator, rear outdoor unit.
Concealed
Ducted unit from a loft or void serving one or two rooms.
Mixed
Consoles downstairs and ducted upstairs on one system.
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 New Malden, 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. 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
On a survey in New Malden 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. Surveys in New Malden cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
