Walk Heathrow and Harmondsworth from Harmondsworth Great Barn outwards and the post-war pattern is obvious: 42% of the 3,318 households in TW6 live in flats, 58% in houses.
Private renting sits at 42% and owner-occupation at 41%; the first group books furniture disposal at short notice, the second plans it.
Walls are cavity brickwork outside — and timber stud partitions inside — which is what a 42% flat share across the ONS neighbourhood covering Heathrow and Harmondsworth actually produces, so the fixing that matters in Heathrow and Harmondsworth is chosen on site — the usual failure here is in TW6, a four-hole bracket with two screws in a stud and two in fresh air — and with 22% one-person households in Heathrow and Harmondsworth, one adult is usually the only pair of hands on site.
Two streets can behave very differently in Heathrow and Harmondsworth: the airport itself plus the villages of Harmondsworth, Sipson and Longford beside it. The quote reflects the street the job is actually on. Heathrow and Harmondsworth 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: airport perimeter security, restricted vehicle zones and drop-off charges; the villages are quiet with driveways. Heathrow Terminals 2 & 3 (Elizabeth line, Piccadilly) is the nearest station, and two crew and a Luton van; three where a wardrobe or corner sofa has to come down a shared stairwell.
