In Islington (N1) the split is 81% flats to 19% houses over 8,725 households, and the stock is Georgian and early Victorian.
Because 27% of Islington is privately rented and 47% socially rented, a lot of N1 work is agreed with a landlord or managing agent rather than the person opening the door.
Expect precast concrete panels and dense blockwork in Islington, often with surface conduit, measured on the walk in from Angel (Northern), with Highbury & Islington to the north rather than assumed from a map 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, as the Islington stock goes, a median age of 34 in this neighbourhood shapes what gets ordered here is the fault we are called back to undo.
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.
Getting to the door matters as much as the job: narrow squares with resident bays, listed frontages and basement flats down external steps. Angel (Northern), with Highbury & Islington to the north is the nearest station, and two crew and a Luton van; three where a wardrobe or corner sofa has to come down a shared stairwell.
