Walk Cheam from Nonsuch Park and Whitehall, Cheam outwards and the inter-war pattern is obvious: 21% of the 13,016 households in SM3 live in flats, 79% in houses.
Private renting sits at 15% and owner-occupation at 81%; the first group books restaurant and cafe clearance at short notice, the second plans it.
Walls are timber stud partitions inside in SM3, cavity brickwork outside — which is what a 21% flat share across the ONS neighbourhood covering Cheam actually produces, so the fixing that matters in Cheam is chosen on site — the usual failure here is in SM3, a four-hole bracket with two screws in a stud and two in fresh air — and driveways on nearly every street; the village parade has short loading bays.
Two streets can behave very differently in Cheam: a village centre with timber-framed buildings and Nonsuch Park on the edge. The quote reflects the street the job is actually on. Cheam is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it.
Getting to the door matters as much as the job: driveways on nearly every street; the village parade has short loading bays. Cheam (Southern) is the nearest station, and two to three operatives as standard, with a specialist F-gas engineer booked in for any unit holding refrigerant-charged equipment.
