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.
Walls are precast concrete panels and dense blockwork; locally that also means often with surface conduit — where 24% owner-occupation means the same home is booked again rather than a new tenant each year, so the fixing that matters in Harlesden is chosen on site — the usual failure here is in NW10, drilling blind into a panel with reinforcement or a buried cable behind it — which is why London Borough of Brent kerb rules get settled before the van is loaded.
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 crew and a Luton for a studio or one-bed; three crew and a second van on two- and three-bedroom apartments or any duplex. Fitters travelling in use Harlesden (Bakerloo, Overground).
