In Walworth (SE17) the split is 89% flats to 11% houses over 7,263 households, and the stock is Georgian and early Victorian.
Because 30% of Walworth is privately rented and 48% socially rented, a lot of SE17 work is agreed with a landlord or managing agent rather than the person opening the door.
Walworth substrates run to precast concrete panels and dense blockwork in SE17, often with surface conduit, measured on the walk in from Elephant & Castle (Northern, Bakerloo) rather than assumed from a map. Nothing is drilled until the wall has been sounded, because drilling blind into a panel with reinforcement or a buried cable behind it, as the Walworth stock goes, the reality on the streets around East Street Market is the mistake that costs a SE17 customer twice.
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.
Market-day closures on East Street, estate service roads and single-lift blocks. Nearest station is Elephant & Castle (Northern, Bakerloo), and two operatives with a transit-sized van as standard, upsized to a Luton for a double garage or a lock-up with heavy workshop contents.
