Census 2021 puts Heathrow and Harmondsworth at 3,318 households with a median age of 34.5. The post-war stock is renter-heavy, which is why 58% houses and 42% flats need different handling in TW6.
Private renting sits at 42% and owner-occupation at 41%; the first group books mirror and artwork hanging at short notice, the second plans it.
Heathrow and Harmondsworth substrates run to 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. Nothing is drilled until the wall has been sounded, because in TW6, a four-hole bracket with two screws in a stud and two in fresh air — with 16% social-rented stock locally, block access is agreed with the estate office first is the mistake that costs a TW6 customer twice.
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 pictures and mirrors up to about 25kg; two for overmantels, full-length glass and anything carried up a communal stairwell. Fitters travelling in use Heathrow Terminals 2 & 3 (Elizabeth line, Piccadilly).
