In Barnsbury (N1) the split is 81% flats to 19% houses over 7,513 households, and the stock is Georgian and early Victorian.
With 30% private renting against 27% owner-occupied, most N1 bookings land on a move-in day rather than a weekend.
Barnsbury substrates run to often with surface conduit — and precast concrete panels and dense blockwork, the pattern behind 7,513 households inside the N1 neighbourhood. Nothing is drilled until the wall has been sounded, because drilling blind into a panel with reinforcement or a buried cable behind it, as the Barnsbury stock goes, which is what a 81% flat share across the ONS neighbourhood covering Barnsbury actually produces is the mistake that costs a N1 customer twice.
Barnsbury 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 — conservation-area squares and crescents west of Upper Street — which is why a N1 quote is not a Islington average.
Getting to the door matters as much as the job: low-traffic neighbourhood filters, narrow squares and heavy basement-step access. Caledonian Road & Barnsbury (Overground) is the nearest station, and one technician with a portable extraction machine and air mover on a single household booking; two technicians on HMO, student accommodation and serviced-apartment rounds where six or more mattresses are cleaned in a day.
