In Bow (E3) the split is 85% flats to 15% houses over 22,995 households, and the stock is mainly Victorian.
The social-housing-led mix here (29% owned, 31% privately rented) means a E3 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Walls are precast concrete panels and dense blockwork; locally that also means often with surface conduit, which is why London Borough of Tower Hamlets kerb rules get settled before the van is loaded, so the fixing that matters in Bow is chosen on site — the usual failure here is drilling blind into a panel with reinforcement or a buried cable behind it, as the Bow stock goes, and with 31% of homes here privately rented, it sets the booking date as often as the job does.
Bow 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 — roman Road market, Bow Quarter's match-factory lofts and canal-side streets — which is why a E3 quote is not a Tower Hamlets average.
Getting to the door matters as much as the job: bow flyover red routes, market-day restrictions and gated conversion estates. Bow Road (District, Hammersmith & City) is the nearest station, and two crew and a Luton on a standard timber shed; three crew where the shed is a workshop size, the base is concrete or the only route out is through the house.
