Census 2021 puts Old Street at 4,949 households with a median age of 31.5. The post-war stock is social-housing-led, which is why 2% houses and 98% flats need different handling in EC1V.
Owner-occupation runs at 19% in Old Street, so alongside the 28% rental churn there is steady planned work — refurbishments, downsizes and probate clearances booked weeks ahead.
Old Street substrates run to often with surface conduit, over precast concrete panels and dense blockwork — which is what a 98% flat share across the ONS neighbourhood covering Old Street actually produces. Nothing is drilled until the wall has been sounded, because in EC1V, drilling blind into a panel with reinforcement or a buried cable behind it — which is why London Borough of Islington kerb rules get settled before the van is loaded 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.
On access, red-route roundabout with no kerbside loading, goods-lift booking in the towers and gated estate yards — one reason two crew and a Luton on a standard mattress and base; the same crew dismantles bunk frames and storage divans on site before the carry. Fitters travelling in use Old Street (Northern, Great Northern).
