Air conditioning in Sidcup
Sidcup holds nine of Bexley's 23 conservation areas and more kinds of house than most of the borough: big Victorian and Edwardian villas near the station, 1930s semis across Lamorbey and Blackfen, flats above the High Street. We install and service air conditioning in all of them, and the first thing we check is which rules your street falls under.

Why does Sidcup have nine of Bexley's 23 conservation areas?
Because it kept more of its past than most suburbs. Bexley Council's list runs to 23 conservation areas, and nine are in Sidcup or Foots Cray: Christ Church, The Green, Halfway Street, The Hollies, Longlands Road, Old Forge Way, The Oval, Willersley Avenue and Braundton Avenue, and Foots Cray itself. Between them they take in the Victorian and Edwardian villas that followed the railway, which reached Sidcup in October 1866, a month after the Dartford Loop Line opened, and later streets as well. In any of them an outdoor unit cannot go on a wall or roof that faces the road, and the council's appraisal for each area says what it wants kept. Send us the address before the survey and we check it against the map. Sources: Bexley Council; Wikipedia; Planning Portal.
Which Sidcup houses overheat, and which are easy to fit?
Wikipedia's description is fair: a mixture of large Victorian and Edwardian properties alongside typical 1930s suburbia. The villas, many of them now divided, are tall, thick-walled and slow to warm but hard to pipe, because the outside wall belongs to the freeholder and the pipes may cross a flat you do not own. The semis of the 1930s suburbia that had lifted Sidcup's population to 12,355 by 1931 are the easy case: one outdoor unit at the rear as permitted development, a bedroom or a loft conversion served from it. Across the borough, 42,154 of 95,298 households live in semis. Sources: Wikipedia; Census 2021; Planning Portal; LEASE.
Which council is in charge of your street?
Usually Bexley, but not always. Sidcup borders Bromley and Greenwich, and several roads in the north of the district, Southspring, Greenhithe Close, Radfield Way and Overmead among them, are governed by the Royal Borough of Greenwich. The planning rules for an outdoor unit are national, but the conservation area maps, the Article 4 directions and the licensing schemes belong to each council, so the first thing we confirm at a Sidcup address is whose portal it goes through. Bexley's rules include an Article 4 direction on small shared houses across the whole borough, in force since 24 September 2017, and another, in force since 10 December 2025, requiring planning permission to turn commercial premises into homes in 13 town centres.

What about the High Street and the hospital end of town?
The High Street had a £1.8 million regeneration in 2014, paid for by Bexley Council, and keeps the pattern of shops with flats above, so a shop unit has to pass the sound test at a bedroom window and go through planning as a commercial installation. At the other end of town, Queen Mary's Hospital opened in 1917 with 300 beds in wooden huts and was, until 1925, the country's centre for the reconstructive surgery of war veterans under Harold Gillies; it reopened as a general hospital in 1930 and the streets around it are the usual Bexley semis. Lamorbey Park and Foots Cray Place are both on the national register of parks and gardens at Grade II, which matters only if an application is needed and the unit would be seen from them. Our commercial air conditioning page covers the shops. Sources: Wikipedia; Bexley Council; Planning Portal.

From first call to first cool night
Tell us about the room
A call to 01322 952910 or the form with your postcode in it. Which room overheats, what the building is, and whether the outside wall is yours to drill.
Survey, then a figure in writing
We measure the room, choose a position for the outdoor unit, calculate the sound at the neighbour's window, look inside the consumer unit and ask about leases, landlords and covenants. The price arrives in writing with the electrics itemised.
Consents settled first
If a freeholder, landlord, management company or council has a say, we wait for it, and we supply the drawings and sound figures they will ask for.
Installed, tested, shown to you
Units, pipes and the new circuit are fitted; the pipework is pressure tested and evacuated before charging; the system runs in both modes while we measure it; the certificates are yours and so is a tour of the remote. After that, a service once a year.
Sidcup questions
Do you cover Foots Cray, Blackfen and Albany Park?
Yes, and Lamorbey, Longlands and New Eltham on the Greenwich side if you ask. Chislehurst is the edge of our patch, so send a postcode.
Our flat is in a converted villa near the station. Possible?
Often, with the freeholder's written consent and the block's one permitted outdoor unit still available. If it has gone, a unit with no outdoor box is the fallback.
Does Sidcup get the same weather as Dartford?
Near enough. Greenwich Observatory, the Met Office station on our Dartford air conditioning page, is about six miles from Sidcup.
