Census 2021 puts Belsize Park at 3,000 households with a median age of 37.8. The mainly Victorian stock is renter-heavy, which is why 7% houses and 93% flats need different handling in NW3.
51% of households rent privately and 39% own, which is why TV mounting demand here peaks around tenancy changeovers and completion dates.
Walls are lath and plaster over timber studs; locally that also means with solid brick on the party and external walls — the reality on the streets around Belsize Village, so the fixing that matters in Belsize Park is chosen on site — the usual failure here is a plasterboard plug spun into lime plaster in NW3, which crumbles the key and drops the panel — which is why London Borough of Camden kerb rules get settled before the van is loaded.
Two streets can behave very differently in Belsize Park: stucco villas and mansion blocks on the slope between Hampstead and Chalk Farm. The quote reflects the street the job is actually on. 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.
On access, resident-permit streets, hill gradients and conversion flats up three or four flights — one reason one fitter up to 43 inches, two for anything larger or where the screen has to go up a stairwell. Fitters travelling in use Belsize Park (Northern).
