The SW1 stock around Westminster Cathedral is inter-war. ONS records 92% flats, 8% houses and 3,844 households in Victoria.
Private renting sits at 30% and owner-occupation at 22%; the first group books cooker cleaning at short notice, the second plans it.
Victoria substrates run to precast concrete panels and dense blockwork in Victoria, often with surface conduit — and with 49% one-person households in Victoria, one adult is usually the only pair of hands on site. Nothing is drilled until the wall has been sounded, because 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 is the mistake that costs a SW1 customer twice.
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 for a freestanding cooker; two for 110cm ranges, where the doors alone are a two-person lift. Fitters travelling in use Victoria (Victoria, Circle, District, National Rail).
