In Westminster and Whitehall (SW1) the split is 95% flats to 5% houses over 3,927 households, and the stock is period conversion.
The renter-heavy mix here (28% owned, 44% privately rented) means a SW1 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Westminster and Whitehall substrates run to dot-and-dab plasterboard over blockwork in Westminster and Whitehall, with metal stud partitions between rooms, with 29% social-rented stock locally, block access is agreed with the estate office first. Nothing is drilled until the wall has been sounded, because Westminster and Whitehall gives us short screws that grip only the board and slowly lever it off the dabs, and with 44% of homes here privately rented, it sets the booking date as often as the job does is the mistake that costs a SW1 customer twice.
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. What shapes the job more is the neighbourhood itself — government quarter around Parliament Square, Whitehall and Smith Square — which is why a SW1 quote is not a Westminster average.
Getting to the door matters as much as the job: security cordons, camera-controlled streets and pre-notified vehicle access on many roads. Westminster (Circle, District, Jubilee) is the nearest station, and one technician and a van-mounted dip tank; two for commercial ranges or where a lift booking limits the time on site.
