In Chelsea (SW3) the split is 78% flats to 22% houses over 8,944 households, and the stock is Georgian and early Victorian.
Because 35% of Chelsea is privately rented and 27% socially rented, a lot of SW3 work is agreed with a landlord or managing agent rather than the person opening the door.
Walls are lath and plaster over timber studs in SW3, with solid brick on the party and external walls, measured on the walk in from Sloane Square (Circle, District) rather than assumed from a map, so the fixing that matters in Chelsea is chosen on site — the usual failure here is a plasterboard plug spun into lime plaster in Chelsea, which crumbles the key and drops the panel, which is what a 78% flat share across the ONS neighbourhood covering Chelsea actually produces.
King's Road shops, Cadogan estate squares and the river at Chelsea Embankment. That character decides the practical detail of hoarder clearance here far more than the borough boundary does. Chelsea 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, cadogan estate parking rules, King's Road red-route loading and mews arches with height limits — one reason two to four operatives depending on severity, with PPE for biohazard handling and a plain, unmarked vehicle available on request. Fitters travelling in use Sloane Square (Circle, District).
