In Mayfair (W1) the split is 88% flats to 12% houses over 3,555 households, and the stock is mixed-era.
The renter-heavy mix here (32% owned, 57% privately rented) means a W1 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Walls are dot-and-dab plasterboard over blockwork in W1, with metal stud partitions between rooms, measured on the walk in from Bond Street (Central, Jubilee, Elizabeth line) rather than assumed from a map, so the fixing that matters in Mayfair is chosen on site — the usual failure here is short screws that grip only the board and slowly lever it off the dabs, as the Mayfair stock goes, where 32% owner-occupation means the same home is booked again rather than a new tenant each year.
Mayfair 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 — grosvenor and Berkeley squares, private members' clubs and the flagship stores of Bond Street — which is why a W1 quote is not a Westminster average.
On access, extremely tight kerbside, mews arches under 2.1m and listed interiors needing floor and stair protection — one reason two crew and a Luton for a studio or one-bed; three crew and a second van on two- and three-bedroom apartments or any duplex. Fitters travelling in use Bond Street (Central, Jubilee, Elizabeth line).
