In Sydenham (SE26) the split is 64% flats to 36% houses over 9,790 households, and the stock is mainly Victorian.
The social-housing-led mix here (45% owned, 22% privately rented) means a SE26 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Sydenham substrates run to often with surface conduit — and precast concrete panels and dense blockwork, which is what a 64% flat share across the ONS neighbourhood covering Sydenham actually produces. Nothing is drilled until the wall has been sounded, because Sydenham gives us drilling blind into a panel with reinforcement or a buried cable behind it, and with 22% of homes here privately rented, it sets the booking date as often as the job does is the mistake that costs a SE26 customer twice.
Sydenham 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 — a long high street on the hill where the Crystal Palace once stood nearby — which is why a SE26 quote is not a Lewisham average.
Steep hills, high-street loading windows and narrow side streets. Nearest station is Sydenham (Overground), and two to four operatives depending on room count, scaling to a second team on a full-floor or full-closure clearance where the schedule is set by a redevelopment date.
