The SE7 stock around Charlton House is mainly Victorian. ONS records 48% flats, 52% houses and 5,904 households in Charlton.
Private renting sits at 20% and owner-occupation at 41%; the first group books shed assembly at short notice, the second plans it.
Charlton substrates run to often with surface conduit — and precast concrete panels and dense blockwork — where 41% owner-occupation means the same home is booked again rather than a new tenant each year. Nothing is drilled until the wall has been sounded, because drilling blind into a panel with reinforcement or a buried cable behind it on these streets — which is why Royal Borough of Greenwich kerb rules get settled before the van is loaded is the mistake that costs a SE7 customer twice.
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.
On access, match-day restrictions at the Valley, steep village hill and riverside estate roads — one reason one fitter for a small shed on a ready base; two for anything over 8x6ft or where roof panels need lifting together. Fitters travelling in use Charlton (Southeastern).
