In Acton (W3) the split is 71% flats to 29% houses over 20,052 households, and the stock is mainly Victorian.
Because 39% of Acton is privately rented and 24% socially rented, a lot of W3 work is agreed with a landlord or managing agent rather than the person opening the door.
Walls are lath and plaster over timber studs; locally that also means with solid brick on the party and external walls, measured on the walk in from Acton Main Line (Elizabeth line) rather than assumed from a map, so the fixing that matters in Acton is chosen on site — the usual failure here is a plasterboard plug spun into lime plaster; locally that also means which crumbles the key and drops the panel, which is what a 71% flat share across the ONS neighbourhood covering Acton actually produces.
Acton 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 — seven stations, Victorian terraces and a fast-changing town centre — which is why a W3 quote is not a Ealing average.
On access, narrow terraced streets with permit bays, plus new towers requiring booked lifts — one reason a two-person crew and a Luton for flats; three or four crew and two vans for houses with lofts, cellars or garages. Fitters travelling in use Acton Main Line (Elizabeth line).
