The N6 stock around Highgate Cemetery is Georgian and early Victorian. ONS records 65% flats, 35% houses and 5,593 households in Highgate.
Owner-occupation runs at 51% in Highgate, so alongside the 37% rental churn there is steady planned work — refurbishments, downsizes and probate clearances booked weeks ahead.
Highgate substrates run to 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. Nothing is drilled until the wall has been sounded, because which crumbles the key and drops the panel — and a plasterboard plug spun into lime plaster — and with 34% one-person households in Highgate, one adult is usually the only pair of hands on site is the mistake that costs a N6 customer twice.
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 one fitter for a typical multi-item visit; two where anything crosses 30kg or has to be carried up a shared stairwell. Fitters travelling in use Highgate (Northern).
