In West Hampstead (NW6) the split is 88% flats to 12% houses over 4,309 households, and the stock is mainly Victorian.

Walls are with solid brick on the party and external walls — and lath and plaster over timber studs, measured on the walk in from West Hampstead (Jubilee, Overground, Thameslink) rather than assumed from a map, 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 NW6, which crumbles the key and drops the panel, a median age of 33 in this neighbourhood shapes what gets ordered here.
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 to three operatives as standard, with a specialist F-gas engineer booked in for any unit holding refrigerant-charged equipment.
