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 blinds and curtain fitting at short notice, the second plans it.
Expect timber stud partitions inside in TW6, cavity brickwork outside — and with 42% of homes here privately rented, it sets the booking date as often as the job does behind the plaster in TW6. That is why fixings are picked in the room rather than off a van shelf, and why 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 is the fault we are called back to undo.
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.
On access, airport perimeter security, restricted vehicle zones and drop-off charges; the villages are quiet with driveways — one reason one fitter for standard windows; two for bent bay tracks or full-height stairwell blinds. Fitters travelling in use Heathrow Terminals 2 & 3 (Elizabeth line, Piccadilly).
