Walk Westminster and Whitehall from The Palace of Westminster outwards and the period conversion pattern is obvious: 95% of the 3,927 households in SW1 live in flats, 5% in houses.
Private renting sits at 44% and owner-occupation at 28%; the first group books appliance clearance at short notice, the second plans it.
Walls are with metal stud partitions between rooms — and dot-and-dab plasterboard over blockwork — which is what a 95% flat share across the ONS neighbourhood covering Westminster and Whitehall actually produces, so the fixing that matters in Westminster and Whitehall is chosen on site — the usual failure here is short screws that grip only the board and slowly lever it off the dabs on these streets — with 29% social-rented stock locally, block access is agreed with the estate office first.
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.
On access, security cordons, camera-controlled streets and pre-notified vehicle access on many roads — one reason two crew and a Luton with a sack barrow; three for American fridge-freezers, range cookers and basement carries. Fitters travelling in use Westminster (Circle, District, Jubilee).
