Census 2021 puts Islington at 8,725 households with a median age of 33.9. The Georgian and early Victorian stock is social-housing-led, which is why 19% houses and 81% flats need different handling in N1.
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.
Expect precast concrete panels and dense blockwork; locally that also means often with surface conduit — which is what a 81% flat share across the ONS neighbourhood covering Islington actually produces behind the plaster in N1. That is why fixings are picked in the room rather than off a van shelf, and why drilling blind into a panel with reinforcement or a buried cable behind it on these streets — and with 36% one-person households in Islington, one adult is usually the only pair of hands on site is the fault we are called back to undo.
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.
On access, narrow squares with resident bays, listed frontages and basement flats down external steps — one reason a two-person crew and a Luton for flats; three or four crew and two vans for houses with lofts, cellars or garages.
