Walk Charlton from Charlton House outwards and the mainly Victorian pattern is obvious: 48% of the 5,904 households in SE7 live in flats, 52% in houses.
Private renting sits at 20% and owner-occupation at 41%; the first group books upholstery cleaning at short notice, the second plans it.
Walls are precast concrete panels and dense blockwork; locally that also means often with surface conduit — which is what a 48% flat share across the ONS neighbourhood covering Charlton actually produces, so the fixing that matters in Charlton is chosen on site — the usual failure here is drilling blind into a panel with reinforcement or a buried cable behind it on these streets — with 38% social-rented stock locally, block access is agreed with the estate office first.
Two streets can behave very differently in Charlton: jacobean Charlton House, the Valley stadium and riverside retail parks. The quote reflects the street the job is actually on. Charlton 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: match-day restrictions at the Valley, steep village hill and riverside estate roads. Charlton (Southeastern) is the nearest station, and one technician with a portable extraction machine — the standard kit for London flats, where a truck-mount hose cannot reach a fourth floor.
