The SW1 stock around The Palace of Westminster is period conversion. ONS records 95% flats, 5% houses and 3,927 households in Westminster and Whitehall.
44% of households rent privately and 28% own, which is why office clearance demand here peaks around tenancy changeovers and completion dates.
Expect with metal stud partitions between rooms — and dot-and-dab plasterboard over blockwork — and with 46% one-person households in Westminster and Whitehall, one adult is usually the only pair of hands on site behind the plaster in SW1. That is why fixings are picked in the room rather than off a van shelf, and why short screws that grip only the board and slowly lever it off the dabs on these streets — measured on the walk in from Westminster (Circle, District, Jubilee) rather than assumed from a map is the fault we are called back to undo.
Two streets can behave very differently in Westminster and Whitehall: government quarter around Parliament Square, Whitehall and Smith Square. The quote reflects the street the job is actually on. Westminster and Whitehall sits inside the Congestion Charge zone as well as ULEZ, so both are itemised on the quote rather than absorbed into an hourly rate.
Security cordons, camera-controlled streets and pre-notified vehicle access on many roads. Nearest station is Westminster (Circle, District, Jubilee), and four crew and a supervisor on a standard floor clearance, scaled up for phased overnight work.
