The SE1 stock around The National Theatre and Tate Modern is post-war. ONS records 94% flats, 6% houses and 4,696 households in South Bank and Waterloo.
44% of households rent privately and 24% own, which is why house and flat clearance demand here peaks around tenancy changeovers and completion dates.
Walls are precast concrete panels and dense blockwork; locally that also means often with surface conduit — measured on the walk in from Waterloo (Jubilee, Northern, Bakerloo, National Rail) rather than assumed from a map, so the fixing that matters in South Bank and Waterloo is chosen on site — the usual failure here is in SE1, drilling blind into a panel with reinforcement or a buried cable behind it — which is why London Borough of Southwark kerb rules get settled before the van is loaded.
Two streets can behave very differently in South Bank and Waterloo: cultural riverfront from the National Theatre to Tate Modern, with Waterloo's flats behind. The quote reflects the street the job is actually on. South Bank and Waterloo sits inside the Congestion Charge zone as well as ULEZ, so both are itemised on the quote rather than absorbed into an hourly rate.
Riverside pedestrian zones, red routes on Stamford Street and event-day closures. Nearest station is Waterloo (Jubilee, Northern, Bakerloo, National Rail), and a two-person crew and a Luton for flats; three or four crew and two vans for houses with lofts, cellars or garages.
