The SW1 stock around Eaton Square is post-war. ONS records 92% flats, 8% houses and 3,844 households in Belgravia.
30% of households rent privately and 22% own, which is why spring cleaning demand here peaks around tenancy changeovers and completion dates.
Expect precast concrete panels and dense blockwork in SW1, often with surface conduit — the pattern behind 3,844 households inside the SW1 neighbourhood behind the plaster in SW1. That is why fixings are picked in the room rather than off a van shelf, and why in SW1, drilling blind into a panel with reinforcement or a buried cable behind it — and with 30% of homes here privately rented, it sets the booking date as often as the job does is the fault we are called back to undo.
Two streets can behave very differently in Belgravia: grosvenor estate stucco, embassies and cobbled mews behind Eaton Square. The quote reflects the street the job is actually on. Belgravia sits inside the Congestion Charge zone as well as ULEZ, so both are itemised on the quote rather than absorbed into an hourly rate.
Estate parking rules, mews arches with height limits and listed staircases requiring protection. Nearest station is Sloane Square (Circle, District), and two cleaners for a flat, two to three for a house, working together in one visit rather than spreading the job across days.
