In St James's (SW1) the split is 95% flats to 5% houses over 3,927 households, and the stock is mixed-era.
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.
Walls are with metal stud partitions between rooms — and dot-and-dab plasterboard over blockwork, and with 44% of homes here privately rented, it sets the booking date as often as the job does, so the fixing that matters in St James's is chosen on site — the usual failure here is St James's gives us short screws that grip only the board and slowly lever it off the dabs, measured on the walk in from Green Park (Piccadilly, Victoria, Jubilee) rather than assumed from a map.
St James's 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 — gentlemen's clubs, galleries and Jermyn Street shirtmakers between the palace and Piccadilly — which is why a SW1 quote is not a Westminster average.
On access, royal Parks restrictions, listed building rules and narrow service entrances off Duke Street — one reason four operatives with a 7.5t tail-lift vehicle on a standard unit, scaling to six with a second vehicle where the handover date is tight. Fitters travelling in use Green Park (Piccadilly, Victoria, Jubilee).
