The SE11 stock around The Kia Oval is Georgian and early Victorian. ONS records 88% flats, 12% houses and 8,644 households in Kennington.
Private renting sits at 25% and owner-occupation at 28%; the first group books clearance services at short notice, the second plans it.
Kennington substrates run to precast concrete panels and dense blockwork; locally that also means often with surface conduit — which is what a 88% flat share across the ONS neighbourhood covering Kennington actually produces. Nothing is drilled until the wall has been sounded, because in SE11, drilling blind into a panel with reinforcement or a buried cable behind it — the pattern behind 8,644 households inside the SE11 neighbourhood is the mistake that costs a SE11 customer twice.
Two streets can behave very differently in Kennington: georgian terraces, the Oval's gasholders and the park between them. The quote reflects the street the job is actually on. 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.
On access, match-day restrictions at the Oval, Duchy estate rules and basement-step access — one reason standard crews are two people with a 3.5-tonne Luton; bigger clears run two vans or return the same day rather than overfilling. Fitters travelling in use Kennington (Northern).
