In West Hampstead (NW6) the split is 88% flats to 12% houses over 4,309 households, and the stock is mainly Victorian.
The renter-heavy mix here (30% owned, 49% privately rented) means a NW6 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Walls are lath and plaster over timber studs in West Hampstead, with solid brick on the party and external walls, and with 40% one-person households in West Hampstead, one adult is usually the only pair of hands on site, so the fixing that matters in West Hampstead is chosen on site — the usual failure here is a plasterboard plug spun into lime plaster in West Hampstead, which crumbles the key and drops the panel, which is what a 88% flat share across the ONS neighbourhood covering West Hampstead actually produces.
West Hampstead 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 — three stations, a busy high street and streets of red-brick Victorian conversions — which is why a NW6 quote is not a Camden average.
On access, very tight parking, narrow terraced streets and flats up two to four flights without lifts — one reason two operatives with a transit-sized van as standard, upsized to a Luton for a double garage or a lock-up with heavy workshop contents.
