Air conditioning in south-west London: what the boroughs ask for
South-west London is where our Surrey engineer network naturally spills over the Greater London boundary — Kingston, Richmond and Sutton were Surrey towns until 1965, and the same engineers work both sides of the line daily. The housing is dense and mostly period: Victorian and Edwardian terraces in Wimbledon, Tooting, Putney, Twickenham and Sutton; inter-war semis across Merton, Croydon and Kingston's suburbs; and a large share of flats, from purpose-built blocks to converted houses and riverside apartments at Kingston and Putney. Loft conversions and rear extensions are everywhere, and the hot top-floor bedroom or glazed kitchen-diner is the single most common reason people get in touch.
Commercially the area is busy in its own right: Croydon's office district, Kingston's retail centre and Thames-side restaurant belt, Wimbledon and Richmond town centres, plus clinics, studios and small offices in every borough. London's urban heat island makes summer nights noticeably warmer than in rural Surrey, and well-insulated terraces and top-floor flats hold that heat — so demand here peaks earliest and lasts longest, and modern units' efficient air-to-air heating makes them a year-round fixture.

2026 UK ranges. London boroughs usually sit at the upper end — labour rates, parking, access and the higher share of flats all push quotes up — so comparing several local figures matters more here than anywhere on our patch.
Planning notes for south-west London installations
Houses across these boroughs follow the national rule: a wall-mounted unit is normally permitted development within siting and size limits. Flats are the big exception. Permitted development rights do not extend to flats, so an outdoor unit on a flat's wall or balcony generally needs planning permission from the borough — and every leaseholder also needs the freeholder or management company's consent in writing before anything is fixed to the building. Engineers who work London flats regularly will tell you early whether a balcony, roof or lightwell position is realistic.
Conservation areas are widespread — Richmond, Kew, Twickenham riverside, Barnes, Wimbledon Village, Kingston's old town, Carshalton, Cheam and parts of central Croydon among many others — and several boroughs use Article 4 directions to withdraw permitted development rights within them, so a visible outdoor unit may need consent even on a house. Listed buildings always need listed building consent. Noise is the other London point: boroughs expect outdoor units sited and specified so they do not disturb neighbours in tight terraces, and engineers we match size and place them with that in mind.
