In Islington (N1) the split is 81% flats to 19% houses over 8,725 households, and the stock is Georgian and early Victorian.
With 27% private renting against 27% owner-occupied, most N1 bookings land on a move-in day rather than a weekend.
Walls are often with surface conduit — and precast concrete panels and dense blockwork, with 47% social-rented stock locally, block access is agreed with the estate office first, so the fixing that matters in Islington is chosen on site — the usual failure here is Islington gives us drilling blind into a panel with reinforcement or a buried cable behind it, a median age of 34 in this neighbourhood shapes what gets ordered here.
Islington 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 — barnsbury and Canonbury squares, antique shops and the Almeida — which is why a N1 quote is not a Islington average.
Narrow squares with resident bays, listed frontages and basement flats down external steps. Nearest station is Highbury & Islington (Victoria, Overground), and two to three operatives as standard, with a specialist F-gas engineer booked in for any unit holding refrigerant-charged equipment.
