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.
Walls are precast concrete panels and dense blockwork in Old Street, often with surface conduit — a median age of 32 in this neighbourhood shapes what gets ordered here, so the fixing that matters in Old Street is chosen on site — the usual failure here is in EC1V, drilling blind into a panel with reinforcement or a buried cable behind it — with 52% social-rented stock locally, block access is agreed with the estate office first.
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 one or two crew depending on access; American-style and full-height units on an upper floor with no lift are booked as a two-person job as standard. Fitters travelling in use Old Street (Northern, Great Northern).
