The N6 stock around Highgate Cemetery is Georgian and early Victorian. ONS records 65% flats, 35% houses and 5,593 households in Highgate.
Private renting sits at 37% and owner-occupation at 51%; the first group books clearance services at short notice, the second plans it.
Walls are lath and plaster over timber studs in Highgate, with solid brick on the party and external walls — which is what a 65% flat share across the ONS neighbourhood covering Highgate actually produces, so the fixing that matters in Highgate is chosen on site — the usual failure here is a plasterboard plug spun into lime plaster in N6, which crumbles the key and drops the panel — which is why London Borough of Haringey kerb rules get settled before the van is loaded.
Two streets can behave very differently in Highgate: hilltop village of Georgian houses, the cemetery and Waterlow Park. The quote reflects the street the job is actually on. Highgate is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it.
On access, steep, narrow lanes where a Luton is the practical limit, plus listed-building constraints — one reason standard crews are two people with a 3.5-tonne Luton; bigger clears run two vans or return the same day rather than overfilling. Fitters travelling in use Highgate (Northern).
