In Walworth (SE17) the split is 89% flats to 11% houses over 7,263 households, and the stock is Georgian and early Victorian.
The social-housing-led mix here (22% owned, 30% privately rented) means a SE17 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Walls are precast concrete panels and dense blockwork in Walworth, often with surface conduit, measured on the walk in from Elephant & Castle (Northern, Bakerloo) rather than assumed from a map, so the fixing that matters in Walworth is chosen on site — the usual failure here is Walworth gives us drilling blind into a panel with reinforcement or a buried cable behind it, which is what a 89% flat share across the ONS neighbourhood covering Walworth actually produces.
Walworth sits inside the Congestion Charge zone as well as ULEZ, so both are itemised on the quote rather than absorbed into an hourly rate. What shapes the job more is the neighbourhood itself — east Street market, Georgian terraces at Walworth Village and the Aylesbury regeneration — which is why a SE17 quote is not a Southwark average.
On access, market-day closures on East Street, estate service roads and single-lift blocks — one reason two operatives with a 3.5t tipper as standard, scaling to four operatives and a 7.5t vehicle on strip-outs or where the waste has to be barrowed a long way to the frontage. Fitters travelling in use Elephant & Castle (Northern, Bakerloo).
