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.
Heathrow and Harmondsworth substrates run to timber stud partitions inside; locally that also means cavity brickwork outside, the pattern behind 3,318 households inside the TW6 neighbourhood. Nothing is drilled until the wall has been sounded, because 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 is the mistake that costs a TW6 customer twice.
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 one fitter for a pivot or fixed screen; two for sliding and bi-fold enclosures and any wet-room panel over 190cm, which is awkward to hold plumb alone.
