In Westbourne Park (W10) the split is 94% flats to 6% houses over 3,175 households, and the stock is post-war.
The social-housing-led mix here (13% owned, 16% privately rented) means a W10 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Westbourne Park substrates run to precast concrete panels and dense blockwork in Westbourne Park, often with surface conduit, which is what a 94% flat share across the ONS neighbourhood covering Westbourne Park actually produces. Nothing is drilled until the wall has been sounded, because Westbourne Park gives us drilling blind into a panel with reinforcement or a buried cable behind it, the pattern behind 3,175 households inside the W10 neighbourhood is the mistake that costs a W10 customer twice.
Westbourne Park 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 — canal-side streets between Notting Hill and Paddington with a strong market culture — which is why a W10 quote is not a Kensington and Chelsea average.
Getting to the door matters as much as the job: canal bridges limit turning, resident bays are permit-only and towpath access is on foot. Westbourne Park (Circle, Hammersmith & City) is the nearest station, and two cleaners for a flat, two to three for a house, working together in one visit rather than spreading the job across days.
