Walk Islington from Islington Green and the Almeida Theatre outwards and the Georgian and early Victorian pattern is obvious: 81% of the 8,725 households in N1 live in flats, 19% in houses.
Owner-occupation runs at 27% in Islington, so alongside the 27% rental churn there is steady planned work — refurbishments, downsizes and probate clearances booked weeks ahead.
Walls are often with surface conduit, over 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 in N1, 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.
Two streets can behave very differently in Islington: barnsbury and Canonbury squares, antique shops and the Almeida. The quote reflects the street the job is actually on. 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.
Narrow squares with resident bays, listed frontages and basement flats down external steps. Nearest station is Highbury & Islington (Victoria, Overground), and one fitter for a pivot or fixed screen; two for sliding and bi-fold enclosures and any wet-room panel over 190cm, which is awkward to hold plumb alone.
