The EC1V stock around Old Street roundabout and Bunhill Fields burial ground is post-war. ONS records 98% flats, 2% houses and 4,949 households in Old Street.
Private renting sits at 28% and owner-occupation at 19%; the first group books washing machine cleaning at short notice, the second plans it.
Old Street substrates run to precast concrete panels and dense blockwork in Old Street, often with surface conduit — which is why London Borough of Islington kerb rules get settled before the van is loaded. Nothing is drilled until the wall has been sounded, because drilling blind into a panel with reinforcement or a buried cable behind it on these streets — measured on the walk in from Old Street (Northern, Great Northern) rather than assumed from a map is the mistake that costs a EC1V customer twice.
Two streets can behave very differently in Old Street: the roundabout, tech offices and warehouse conversions on the City fringe. The quote reflects the street the job is actually on. Old Street sits inside the Congestion Charge zone as well as ULEZ, so both are itemised on the quote rather than absorbed into an hourly rate.
Red-route roundabout with no kerbside loading, goods-lift booking in the towers and gated estate yards. Nearest station is Old Street (Northern, Great Northern), and one technician; the visit is usually booked alongside an oven or fridge clean to make the London call-out worth it.
