Census 2021 puts Dartmouth Park at 3,395 households with a median age of 41.9. The mainly Victorian stock is social-housing-led, which is why 28% houses and 72% flats need different handling in NW5.
Private renting sits at 18% and owner-occupation at 45%; the first group books oven cleaning at short notice, the second plans it.
Walls are precast concrete panels and dense blockwork in Dartmouth Park, often with surface conduit — which is what a 72% flat share across the ONS neighbourhood covering Dartmouth Park actually produces, so the fixing that matters in Dartmouth Park is chosen on site — the usual failure here is in NW5, drilling blind into a panel with reinforcement or a buried cable behind it — the pattern behind 3,395 households inside the NW5 neighbourhood.
Two streets can behave very differently in Dartmouth Park: steep Victorian streets between Highgate Cemetery and the eastern edge of Hampstead Heath. The quote reflects the street the job is actually on. Dartmouth 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.
Getting to the door matters as much as the job: steep gradients, resident permit bays and long communal stair runs in the conversions. Tufnell Park (Northern) is the nearest station, and one technician and a van-mounted dip tank; two for commercial ranges or where a lift booking limits the time on site.
