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.
Angel substrates run to lath and plaster over timber studs; locally that also means with solid brick on the party and external walls, the pattern behind 4,920 households inside the N1 neighbourhood. Nothing is drilled until the wall has been sounded, because which crumbles the key and drops the panel, over a plasterboard plug spun into lime plaster, where 34% owner-occupation means the same home is booked again rather than a new tenant each year is the mistake that costs a N1 customer twice.
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.
Getting to the door matters as much as the job: seven-day CPZ, no off-street parking on the Georgian streets and steep basement access. Angel (Northern) is the nearest station, and two to three operatives as standard, with a specialist F-gas engineer booked in for any unit holding refrigerant-charged equipment.
