In Sutton (SM1) the split is 59% flats to 41% houses over 22,476 households, and the stock is mainly Victorian.
Because 32% of Sutton is privately rented and 13% socially rented, a lot of SM1 work is agreed with a landlord or managing agent rather than the person opening the door.
Sutton substrates run to lath and plaster over timber studs; locally that also means with solid brick on the party and external walls, a median age of 38 in this neighbourhood shapes what gets ordered here. Nothing is drilled until the wall has been sounded, because a plasterboard plug spun into lime plaster in SM1, which crumbles the key and drops the panel, which is what a 59% flat share across the ONS neighbourhood covering Sutton actually produces is the mistake that costs a SM1 customer twice.
Sutton is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it. What shapes the job more is the neighbourhood itself — a long pedestrianised high street with the Trinity Square district behind — which is why a SM1 quote is not a Sutton average.
Getting to the door matters as much as the job: pedestrianised high street with timed vehicle access; driveways on the residential roads. Sutton (Southern, Thameslink) is the nearest station, and two to four operatives depending on severity, with PPE for biohazard handling and a plain, unmarked vehicle available on request.
