In Woolwich (SE18) the split is 63% flats to 37% houses over 13,241 households, and the stock is post-war.
Because 25% of Woolwich is privately rented and 47% socially rented, a lot of SE18 work is agreed with a landlord or managing agent rather than the person opening the door.
Expect precast concrete panels and dense blockwork in Woolwich, often with surface conduit, and with 31% one-person households in Woolwich, one adult is usually the only pair of hands on site behind the plaster in SE18. That is why fixings are picked in the room rather than off a van shelf, and why Woolwich gives us drilling blind into a panel with reinforcement or a buried cable behind it, which is what a 63% flat share across the ONS neighbourhood covering Woolwich actually produces is the fault we are called back to undo.
Woolwich 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 — the Arsenal's converted barracks, a market town centre and the ferry across the river — which is why a SE18 quote is not a Greenwich average.
On access, royal Arsenal estate permits, town-centre one-way loading and booked lifts in the towers — 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 Woolwich (Elizabeth line, DLR).
