Walk South Bank and Waterloo from The National Theatre and Tate Modern outwards and the post-war pattern is obvious: 94% of the 4,696 households in SE1 live in flats, 6% in houses.
44% of households rent privately and 24% own, which is why appliance clearance demand here peaks around tenancy changeovers and completion dates.
Expect precast concrete panels and dense blockwork; locally that also means often with surface conduit — with 31% social-rented stock locally, block access is agreed with the estate office first behind the plaster in SE1. That is why fixings are picked in the room rather than off a van shelf, and why drilling blind into a panel with reinforcement or a buried cable behind it on these streets — measured on the walk in from Waterloo (Jubilee, Northern, Bakerloo, National Rail) rather than assumed from a map is the fault we are called back to undo.
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.
On access, riverside pedestrian zones, red routes on Stamford Street and event-day closures — one reason two crew and a Luton with a sack barrow; three for American fridge-freezers, range cookers and basement carries. Fitters travelling in use Waterloo (Jubilee, Northern, Bakerloo, National Rail).
