Walk Woolwich from The Royal Arsenal and Woolwich Ferry outwards and the post-war pattern is obvious: 63% of the 13,241 households in SE18 live in flats, 37% in houses.
Owner-occupation runs at 28% in Woolwich, so alongside the 25% rental churn there is steady planned work — refurbishments, downsizes and probate clearances booked weeks ahead.
Walls are precast concrete panels and dense blockwork; locally that also means often with surface conduit — which is what a 63% flat share across the ONS neighbourhood covering Woolwich actually produces, so the fixing that matters in Woolwich is chosen on site — the usual failure here is in SE18, drilling blind into a panel with reinforcement or a buried cable behind it — the pattern behind 13,241 households inside the SE18 neighbourhood.
Two streets can behave very differently in Woolwich: the Arsenal's converted barracks, a market town centre and the ferry across the river. The quote reflects the street the job is actually on. Woolwich is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it.
Getting to the door matters as much as the job: royal Arsenal estate permits, town-centre one-way loading and booked lifts in the towers. Woolwich (Elizabeth line, DLR) is the nearest station, and four operatives with a 7.5t tail-lift vehicle on a standard unit, scaling to six with a second vehicle where the handover date is tight.
