Walk Victoria from Westminster Cathedral outwards and the inter-war pattern is obvious: 92% of the 3,844 households in SW1 live in flats, 8% in houses.
Private renting sits at 30% and owner-occupation at 22%; the first group books driveway cleaning at short notice, the second plans it.
Walls are precast concrete panels and dense blockwork in SW1, often with surface conduit — and with 30% of homes here privately rented, it sets the booking date as often as the job does, so the fixing that matters in Victoria is chosen on site — the usual failure here is drilling blind into a panel with reinforcement or a buried cable behind it on these streets — measured on the walk in from Victoria (Victoria, Circle, District, National Rail) rather than assumed from a map.
Two streets can behave very differently in Victoria: station district of offices, theatres and new mixed-use blocks around Nova. The quote reflects the street the job is actually on. Victoria 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, coach-station traffic, red routes on Vauxhall Bridge Road and dock booking in the newer blocks — one reason one technician and a van-mounted hot-water pressure washer for most driveways; two on larger block-paving jobs where re-sanding is included, since brushing sand in is a second task run alongside the wash.
