Census 2021 puts Mayfair at 3,555 households with a median age of 38.4. The mixed-era stock is renter-heavy, which is why 12% houses and 88% flats need different handling in W1.
Private renting sits at 57% and owner-occupation at 32%; the first group books construction site clearance at short notice, the second plans it.
Expect dot-and-dab plasterboard over blockwork in W1, with metal stud partitions between rooms — the pattern behind 3,555 households inside the W1 neighbourhood behind the plaster in W1. That is why fixings are picked in the room rather than off a van shelf, and why in W1, short screws that grip only the board and slowly lever it off the dabs — which is why Westminster City Council kerb rules get settled before the van is loaded is the fault we are called back to undo.
Two streets can behave very differently in Mayfair: grosvenor and Berkeley squares, private members' clubs and the flagship stores of Bond Street. The quote reflects the street the job is actually on. 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.
Getting to the door matters as much as the job: extremely tight kerbside, mews arches under 2.1m and listed interiors needing floor and stair protection. Bond Street (Central, Jubilee, Elizabeth line) is the nearest station, and two operatives with a 3.5t tipper as standard, scaling to four operatives and a 7.5t vehicle on strip-outs or where the waste has to be barrowed a long way to the frontage.
