In Heathrow and Harmondsworth (TW6) the split is 42% flats to 58% houses over 3,318 households, and the stock is post-war.
With 42% private renting against 41% owner-occupied, most TW6 bookings land on a move-in day rather than a weekend.
Walls are cavity brickwork outside, over timber stud partitions inside, 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 Heathrow and Harmondsworth gives us a four-hole bracket with two screws in a stud and two in fresh air, where 41% owner-occupation means the same home is booked again rather than a new tenant each year.
The airport itself plus the villages of Harmondsworth, Sipson and Longford beside it. That character decides the practical detail of business clearance here far more than the borough boundary does. Heathrow and Harmondsworth is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it.
On access, airport perimeter security, restricted vehicle zones and drop-off charges; the villages are quiet with driveways — one reason two crew and a Luton on a small office or shop unit; three to four crew with a 7.5-tonne vehicle on retail strip-outs, warehouses and racking removals. Fitters travelling in use Heathrow Terminals 2 & 3 (Elizabeth line, Piccadilly).
