Walk Highbury from Highbury Fields and the Emirates Stadium outwards and the mainly Victorian pattern is obvious: 77% of the 7,327 households in N5 live in flats, 23% in houses.
Private renting sits at 30% and owner-occupation at 37%; the first group books extractor fan cleaning at short notice, the second plans it.
Highbury substrates run to often with surface conduit, over precast concrete panels and dense blockwork — which is what a 77% flat share across the ONS neighbourhood covering Highbury actually produces. Nothing is drilled until the wall has been sounded, because in N5, drilling blind into a panel with reinforcement or a buried cable behind it — which is why London Borough of Islington kerb rules get settled before the van is loaded is the mistake that costs a N5 customer twice.
Two streets can behave very differently in Highbury: highbury Fields, Arsenal match days and streets of tall Victorian terraces. The quote reflects the street the job is actually on. Highbury 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: match-day road closures and controlled parking, plus flats three or four floors up without lifts. Highbury & Islington (Victoria, Overground) is the nearest station, and one technician for domestic hoods and bathroom fans; two for island canopies and any commercial kitchen.
