In Spitalfields (E1) the split is 88% flats to 12% houses over 4,012 households, and the stock is Georgian and early Victorian.
The renter-heavy mix here (22% owned, 48% privately rented) means a E1 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Spitalfields substrates run to dot-and-dab plasterboard over blockwork; locally that also means with metal stud partitions between rooms, with 30% social-rented stock locally, block access is agreed with the estate office first. 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 Spitalfields stock goes, which is what a 88% flat share across the ONS neighbourhood covering Spitalfields actually produces is the mistake that costs a E1 customer twice.
Spitalfields 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 — georgian silk-weavers' houses, the market and Brick Lane's curry houses — which is why a E1 quote is not a Tower Hamlets average.
Getting to the door matters as much as the job: listed staircases and shutters, market-day closures and City-fringe loading windows. Liverpool Street (Elizabeth line, Central, Circle) is the nearest station, and two operatives with a transit-sized van as standard, upsized to a Luton for a double garage or a lock-up with heavy workshop contents.
