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.
Private renting sits at 44% and owner-occupation at 24%; the first group books retail and shop clearance at short notice, the second plans it.
South Bank and Waterloo substrates run to often with surface conduit, over precast concrete panels and dense blockwork — which is what a 94% flat share across the ONS neighbourhood covering South Bank and Waterloo actually produces. Nothing is drilled until the wall has been sounded, because in SE1, drilling blind into a panel with reinforcement or a buried cable behind it — the pattern behind 4,696 households inside the SE1 neighbourhood is the mistake that costs a SE1 customer twice.
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 two to three operatives for a small or mid-size unit, with access equipment booked separately for fascia and signage above ground floor level.
