In Wallington (SM6) the split is 43% flats to 57% houses over 7,054 households, and the stock is mainly Edwardian.
The owner-occupier-led mix here (66% owned, 22% privately rented) means a SM6 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Wallington substrates run to cavity brickwork outside — and timber stud partitions inside, which is why London Borough of Sutton kerb rules get settled before the van is loaded. Nothing is drilled until the wall has been sounded, because a four-hole bracket with two screws in a stud and two in fresh air, as the Wallington stock goes, and with 22% of homes here privately rented, it sets the booking date as often as the job does is the mistake that costs a SM6 customer twice.
Wallington 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 — edwardian avenues, a compact high street and Beddington Park nearby — which is why a SM6 quote is not a Sutton average.
On access, wide avenues with driveways; the high street has timed loading bays — one reason one or two crew depending on access; American-style and full-height units on an upper floor with no lift are booked as a two-person job as standard. Fitters travelling in use Wallington (Southern).
