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.
Private renting sits at 27% and owner-occupation at 27%; the first group books cooker cleaning at short notice, the second plans it.
Walls are precast concrete panels and dense blockwork in Islington, often with surface conduit — a median age of 34 in this neighbourhood shapes what gets ordered here, so the fixing that matters in Islington is chosen on site — the usual failure here is drilling blind into a panel with reinforcement or a buried cable behind it on these streets — with 47% social-rented stock locally, block access is agreed with the estate office first.
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 one technician for a freestanding cooker; two for 110cm ranges, where the doors alone are a two-person lift. Fitters travelling in use Highbury & Islington (Victoria, Overground).
