In Belsize Park (NW3) the split is 93% flats to 7% houses over 3,000 households, and the stock is mainly Victorian.
Because 51% of Belsize Park is privately rented and 10% socially rented, a lot of NW3 work is agreed with a landlord or managing agent rather than the person opening the door.
Belsize Park substrates run to lath and plaster over timber studs in NW3, with solid brick on the party and external walls, which is why London Borough of Camden kerb rules get settled before the van is loaded. Nothing is drilled until the wall has been sounded, because a plasterboard plug spun into lime plaster in NW3, which crumbles the key and drops the panel, which is what a 93% flat share across the ONS neighbourhood covering Belsize Park actually produces is the mistake that costs a NW3 customer twice.
Belsize Park 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 — stucco villas and mansion blocks on the slope between Hampstead and Chalk Farm — which is why a NW3 quote is not a Camden average.
Resident-permit streets, hill gradients and conversion flats up three or four flights. Nearest station is Belsize Park (Northern), and three to six operatives depending on the plant, with skates, pallet trucks and a tail-lift 7.5t as standard and a HIAB where a machine cannot be moved to the bay by hand.
