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 wallpaper hanging demand here peaks around tenancy changeovers and completion dates.
Walls are precast concrete panels and dense blockwork in SW1, often with surface conduit — and with 30% of homes here privately rented, it sets the booking date as often as the job does, so the fixing that matters in Belgravia is chosen on site — the usual failure here is in SW1, drilling blind into a panel with reinforcement or a buried cable behind it — which is why Westminster City Council kerb rules get settled before the van is loaded.
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.
Getting to the door matters as much as the job: estate parking rules, mews arches with height limits and listed staircases requiring protection. Sloane Square (Circle, District) is the nearest station, and one decorator for a feature wall or single room; two for stairwells, long drops and murals that must be hung to a strict sequence.
