In Canary Wharf (E14) the split is 98% flats to 2% houses over 3,528 households, and the stock is recent new-build.
Because 59% of Canary Wharf is privately rented and 15% socially rented, a lot of E14 work is agreed with a landlord or managing agent rather than the person opening the door.
Canary Wharf substrates run to with metal stud partitions between rooms, over dot-and-dab plasterboard over blockwork, which is why London Borough of Tower Hamlets kerb rules get settled before the van is loaded. Nothing is drilled until the wall has been sounded, because short screws that grip only the board and slowly lever it off the dabs, as the Canary Wharf stock goes, and with 59% of homes here privately rented, it sets the booking date as often as the job does is the mistake that costs a E14 customer twice.
Canary Wharf sits inside the Congestion Charge zone as well as ULEZ, so both are itemised on the quote rather than absorbed into an hourly rate. What shapes the job more is the neighbourhood itself — tower cluster of banks, malls and high-rise apartments on the old West India Docks — which is why a E14 quote is not a Tower Hamlets average.
On access, estate permits from Canary Wharf Management, booked goods lifts and loading docks below ground — 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.
