In Angel (N1) the split is 75% flats to 25% houses over 4,920 households, and the stock is Georgian and early Victorian.
The renter-heavy mix here (34% owned, 37% privately rented) means a N1 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Walls are with solid brick on the party and external walls, over lath and plaster over timber studs, where 34% owner-occupation means the same home is booked again rather than a new tenant each year, so the fixing that matters in Angel is chosen on site — the usual failure here is a plasterboard plug spun into lime plaster; locally that also means which crumbles the key and drops the panel, and with 37% of homes here privately rented, it sets the booking date as often as the job does.
Angel 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 — upper Street's bars and theatres, canal basin flats and Georgian squares — which is why a N1 quote is not a Islington average.
On access, seven-day CPZ, no off-street parking on the Georgian streets and steep basement access — one reason two operatives with a 3.5t tipper as standard, scaling to four operatives and a 7.5t vehicle on strip-outs or where the waste has to be barrowed a long way to the frontage.
