In Soho (W1) the split is 98% flats to 2% houses over 4,257 households, and the stock is Georgian and early Victorian.
The renter-heavy mix here (20% owned, 52% privately rented) means a W1 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, which is why Westminster City Council kerb rules get settled before the van is loaded, so the fixing that matters in Soho is chosen on site — the usual failure here is Soho gives us short screws that grip only the board and slowly lever it off the dabs, which is what a 98% flat share across the ONS neighbourhood covering Soho actually produces.
Soho 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 — post-production studios, restaurants and above-shop flats packed into a Georgian grid — which is why a W1 quote is not a Westminster average.
On access, pedestrian zones, night-time economy congestion and no lifts in most walk-ups — carry-up is the default — one reason one technician for a freestanding cooker; two for 110cm ranges, where the doors alone are a two-person lift.
