In Kennington (SE11) the split is 88% flats to 12% houses over 8,644 households, and the stock is Georgian and early Victorian.
Because 25% of Kennington is privately rented and 47% socially rented, a lot of SE11 work is agreed with a landlord or managing agent rather than the person opening the door.
Walls are often with surface conduit — and precast concrete panels and dense blockwork, with 47% social-rented stock locally, block access is agreed with the estate office first, so the fixing that matters in Kennington is chosen on site — the usual failure here is Kennington gives us drilling blind into a panel with reinforcement or a buried cable behind it, the reality on the streets around The Kia Oval.
Kennington 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 — georgian terraces, the Oval's gasholders and the park between them — which is why a SE11 quote is not a Lambeth average.
Getting to the door matters as much as the job: match-day restrictions at the Oval, Duchy estate rules and basement-step access. Kennington (Northern) is the nearest station, and two to three operatives for a small or mid-size unit, with access equipment booked separately for fascia and signage above ground floor level.
