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 TV mounting at short notice, the second plans it.
Highgate substrates run to lath and plaster over timber studs in Highgate, with solid brick on the party and external walls — where 51% owner-occupation means the same home is booked again rather than a new tenant each year. Nothing is drilled until the wall has been sounded, because which crumbles the key and drops the panel, over a plasterboard plug spun into lime plaster — the pattern behind 5,593 households inside the N6 neighbourhood 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.
Getting to the door matters as much as the job: steep, narrow lanes where a Luton is the practical limit, plus listed-building constraints. Highgate (Northern) is the nearest station, and one fitter up to 43 inches, two for anything larger or where the screen has to go up a stairwell.
