Walk Kensington from Kensington Palace outwards and the period conversion pattern is obvious: 83% of the 13,346 households in W8 live in flats, 17% in houses.
46% of households rent privately and 35% own, which is why oven cleaning demand here peaks around tenancy changeovers and completion dates.
Walls are with solid brick on the party and external walls, over lath and plaster over timber studs — which is why Royal Borough of Kensington and Chelsea kerb rules get settled before the van is loaded, so the fixing that matters in Kensington is chosen on site — the usual failure here is a plasterboard plug spun into lime plaster in Kensington, which crumbles the key and drops the panel — where 35% owner-occupation means the same home is booked again rather than a new tenant each year.
Two streets can behave very differently in Kensington: the high street, palace gardens and the quiet garden squares of Kensington proper. The quote reflects the street the job is actually on. Kensington 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: mansion blocks with cage lifts and porter sign-in; Kensington High Street loading windows are short. High Street Kensington (Circle, District) is the nearest station, and one technician and a van-mounted dip tank; two for commercial ranges or where a lift booking limits the time on site.
