Walk Hanwell from The Wharncliffe Viaduct outwards and the mainly Victorian pattern is obvious: 45% of the 3,219 households in W7 live in flats, 55% in houses.
Private renting sits at 31% and owner-occupation at 55%; the first group books TV mounting at short notice, the second plans it.
Hanwell substrates run to some of it dry-lined during a later refurbishment, over solid London stock brick — and with 31% of homes here privately rented, it sets the booking date as often as the job does. Nothing is drilled until the wall has been sounded, because in W7, fixings landing in soft lime mortar joints instead of the brick body — and with 27% one-person households in Hanwell, one adult is usually the only pair of hands on site is the mistake that costs a W7 customer twice.
Two streets can behave very differently in Hanwell: the Wharncliffe Viaduct, the Brent valley and a village-like clock tower centre. The quote reflects the street the job is actually on. Hanwell is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it.
Getting to the door matters as much as the job: narrow bridges over the Brent, permit bays near the station and driveways elsewhere. Hanwell (Elizabeth line) is the nearest station, and one fitter up to 43 inches, two for anything larger or where the screen has to go up a stairwell.
