Census 2021 puts Belgravia at 3,844 households with a median age of 38.1. The post-war stock is social-housing-led, which is why 8% houses and 92% flats need different handling in SW1.
30% of households rent privately and 22% own, which is why BBQ cleaning demand here peaks around tenancy changeovers and completion dates.
Walls are precast concrete panels and dense blockwork in SW1, often with surface conduit — which is what a 92% flat share across the ONS neighbourhood covering Belgravia actually produces, so the fixing that matters in Belgravia is chosen on site — the usual failure here is drilling blind into a panel with reinforcement or a buried cable behind it on these streets — with 48% social-rented stock locally, block access is agreed with the estate office first.
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 one technician with a van-mounted dip tank; two where a barbecue has to be carried through a flat to reach a terrace.
