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.
Chelsea substrates run to lath and plaster over timber studs in Chelsea, with solid brick on the party and external walls, measured on the walk in from South Kensington (Circle, District, Piccadilly), with Sloane Square east rather than assumed from a map. Nothing is drilled until the wall has been sounded, because a plasterboard plug spun into lime plaster in SW3, which crumbles the key and drops the panel, where 38% owner-occupation means the same home is booked again rather than a new tenant each year is the mistake that costs a SW3 customer twice.
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. What shapes the job more is the neighbourhood itself — king's Road shops, Cadogan estate squares and the river at Chelsea Embankment — which is why a SW3 quote is not a Kensington and Chelsea average.
Cadogan estate parking rules, King's Road red-route loading and mews arches with height limits. Nearest station is South Kensington (Circle, District, Piccadilly), with Sloane Square east, and two crew and a Luton or tipper; three where everything has to be carried through a hallway.
