Census 2021 puts Harlesden at 5,538 households with a median age of 35.8. The mainly Victorian stock is renter-heavy, which is why 22% houses and 78% flats need different handling in NW10.
Owner-occupation runs at 24% in Harlesden, so alongside the 41% rental churn there is steady planned work — refurbishments, downsizes and probate clearances booked weeks ahead.
Harlesden substrates run to precast concrete panels and dense blockwork; locally that also means often with surface conduit — with 35% social-rented stock locally, block access is agreed with the estate office first. Nothing is drilled until the wall has been sounded, because in NW10, drilling blind into a panel with reinforcement or a buried cable behind it — measured on the walk in from Harlesden (Bakerloo, Overground) rather than assumed from a map is the mistake that costs a NW10 customer twice.
Two streets can behave very differently in Harlesden: jubilee Clock, Caribbean food shops and a working high street. The quote reflects the street the job is actually on. Harlesden is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it.
On access, very busy high street with short loading bays; side streets are narrow and permit-only — one reason two to four operatives for a single-building clear, scaling to two teams working in parallel where a full primary site has to be finished inside a two-week holiday window. Fitters travelling in use Harlesden (Bakerloo, Overground).
