In Victoria (SW1) the split is 92% flats to 8% houses over 3,844 households, and the stock is inter-war.
Because 30% of Victoria is privately rented and 48% socially rented, a lot of SW1 work is agreed with a landlord or managing agent rather than the person opening the door.
Expect precast concrete panels and dense blockwork; locally that also means often with surface conduit, with 48% social-rented stock locally, block access is agreed with the estate office first behind the plaster in SW1. That is why fixings are picked in the room rather than off a van shelf, and why Victoria gives us drilling blind into a panel with reinforcement or a buried cable behind it, the reality on the streets around Westminster Cathedral is the fault we are called back to undo.
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. What shapes the job more is the neighbourhood itself — station district of offices, theatres and new mixed-use blocks around Nova — which is why a SW1 quote is not a Westminster average.
On access, coach-station traffic, red routes on Vauxhall Bridge Road and dock booking in the newer blocks — one reason two operatives with a 3.5t tipper as standard, scaling to four operatives and a 7.5t vehicle on strip-outs or where the waste has to be barrowed a long way to the frontage.
