In Shadwell (E1) the split is 92% flats to 8% houses over 5,744 households, and the stock is post-war.
The social-housing-led mix here (25% owned, 34% privately rented) means a E1 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Expect precast concrete panels and dense blockwork in E1, often with surface conduit, with 41% social-rented stock locally, block access is agreed with the estate office first behind the plaster in E1. That is why fixings are picked in the room rather than off a van shelf, and why drilling blind into a panel with reinforcement or a buried cable behind it, as the Shadwell stock goes, where 25% owner-occupation means the same home is booked again rather than a new tenant each year is the fault we are called back to undo.
Shadwell 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 — basin flats, Watney Market and the streets between Whitechapel and the river — which is why a E1 quote is not a Tower Hamlets average.
On access, the Highway red route, cycle-superhighway kerb build-outs and estate lift booking — one reason 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. Fitters travelling in use Shadwell (DLR, Overground).
