In Heathrow and Harmondsworth (TW6) the split is 42% flats to 58% houses over 3,318 households, and the stock is post-war.
Because 42% of Heathrow and Harmondsworth is privately rented and 16% socially rented, a lot of TW6 work is agreed with a landlord or managing agent rather than the person opening the door.
Walls are timber stud partitions inside in Heathrow and Harmondsworth, cavity brickwork outside, the pattern behind 3,318 households inside the TW6 neighbourhood, so the fixing that matters in Heathrow and Harmondsworth is chosen on site — the usual failure here is a four-hole bracket with two screws in a stud and two in fresh air, as the Heathrow and Harmondsworth stock goes, a median age of 35 in this neighbourhood shapes what gets ordered here.
Heathrow and Harmondsworth is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it. What shapes the job more is the neighbourhood itself — the airport itself plus the villages of Harmondsworth, Sipson and Longford beside it — which is why a TW6 quote is not a Hillingdon average.
Airport perimeter security, restricted vehicle zones and drop-off charges; the villages are quiet with driveways. Nearest station is Heathrow Terminals 2 & 3 (Elizabeth line, Piccadilly), and a two-person crew and a Luton for flats; three or four crew and two vans for houses with lofts, cellars or garages.
