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.
Private renting sits at 35% and owner-occupation at 32%; the first group books commercial cleaning at short notice, the second plans it.
Colindale substrates run to often with surface conduit, over precast concrete panels and dense blockwork — a median age of 32 in this neighbourhood shapes what gets ordered here. Nothing is drilled until the wall has been sounded, because in NW9, drilling blind into a panel with reinforcement or a buried cable behind it — and with 30% one-person households in Colindale, one adult is usually the only pair of hands on site is the mistake that costs a NW9 customer twice.
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 to four operatives depending on floor area, with a named supervisor and a mobile cover team for sickness.
