In Belgravia (SW1) the split is 92% flats to 8% houses over 3,844 households, and the stock is post-war.
The social-housing-led mix here (22% owned, 30% privately rented) means a SW1 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Expect precast concrete panels and dense blockwork; locally that also means often with surface conduit, which is why Westminster City Council kerb rules get settled before the van is loaded behind the plaster in SW1. 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, as the Belgravia stock goes, a median age of 38 in this neighbourhood shapes what gets ordered here is the fault we are called back to undo.
Grosvenor estate stucco, embassies and cobbled mews behind Eaton Square. That character decides the practical detail of hoarder clearance here far more than the borough boundary does. 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 two to four operatives depending on severity, with PPE for biohazard handling and a plain, unmarked vehicle available on request.
