Walk Colindale from The former Hendon Aerodrome and Colindale Gardens outwards and the inter-war pattern is obvious: 80% of the 7,659 households in NW9 live in flats, 20% in houses.
Owner-occupation runs at 32% in Colindale, so alongside the 35% rental churn there is steady planned work — refurbishments, downsizes and probate clearances booked weeks ahead.
Expect often with surface conduit, over precast concrete panels and dense blockwork — the pattern behind 7,659 households inside the NW9 neighbourhood behind the plaster in NW9. That is why fixings are picked in the room rather than off a van shelf, and why in NW9, drilling blind into a panel with reinforcement or a buried cable behind it — and with 35% of homes here privately rented, it sets the booking date as often as the job does is the fault we are called back to undo.
Two streets can behave very differently in Colindale: the fastest-growing new-build district in north London, around the old aerodrome. The quote reflects the street the job is actually on. Colindale is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it.
Getting to the door matters as much as the job: every new block requires booked goods lifts and loading bays; estate roads are gated. Colindale (Northern) is the nearest station, and one technician for domestic hoods and bathroom fans; two for island canopies and any commercial kitchen.
