In Sudbury and Alperton (HA0) the split is 47% flats to 53% houses over 12,166 households, and the stock is inter-war.
With 38% private renting against 47% owner-occupied, most HA0 bookings land on a move-in day rather than a weekend.
Sudbury and Alperton substrates run to with solid brick on the party and external walls — and lath and plaster over timber studs, measured on the walk in from Alperton (Piccadilly) rather than assumed from a map. Nothing is drilled until the wall has been sounded, because a plasterboard plug spun into lime plaster in HA0, which crumbles the key and drops the panel, where 47% owner-occupation means the same home is booked again rather than a new tenant each year is the mistake that costs a HA0 customer twice.
Sudbury and Alperton 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 — canal-side new-build towers beside Metroland semis and industrial units — which is why a HA0 quote is not a Brent average.
On access, canal bridges limit turning; towers require booked service lifts and loading bays — one reason two cleaners for a flat, two to three for a house, working together in one visit rather than spreading the job across days. Fitters travelling in use Alperton (Piccadilly).
