In Highbury (N5) the split is 77% flats to 23% houses over 7,327 households, and the stock is mainly Victorian.
The social-housing-led mix here (37% owned, 30% privately rented) means a N5 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Walls are often with surface conduit — and precast concrete panels and dense blockwork, the pattern behind 7,327 households inside the N5 neighbourhood, so the fixing that matters in Highbury is chosen on site — the usual failure here is Highbury gives us drilling blind into a panel with reinforcement or a buried cable behind it, which is what a 77% flat share across the ONS neighbourhood covering Highbury actually produces.
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. What shapes the job more is the neighbourhood itself — highbury Fields, Arsenal match days and streets of tall Victorian terraces — which is why a N5 quote is not a Islington average.
Match-day road closures and controlled parking, plus flats three or four floors up without lifts. Nearest station is Highbury & Islington (Victoria, Overground), and two to four operatives depending on room count, scaling to a second team on a full-floor or full-closure clearance where the schedule is set by a redevelopment date.
