In Kennington (SE11) the split is 88% flats to 12% houses over 8,644 households, and the stock is Georgian and early Victorian.
The social-housing-led mix here (28% owned, 25% privately rented) means a SE11 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Walls are precast concrete panels and dense blockwork; locally that also means often with surface conduit, measured on the walk in from Kennington (Northern) rather than assumed from a map, 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, where 28% owner-occupation means the same home is booked again rather than a new tenant each year.
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.
On access, match-day restrictions at the Oval, Duchy estate rules and basement-step access — 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.
