In Camberwell (SE5) the split is 83% flats to 17% houses over 12,806 households, and the stock is Georgian and early Victorian.
Because 24% of Camberwell is privately rented and 44% socially rented, a lot of SE5 work is agreed with a landlord or managing agent rather than the person opening the door.
Walls are precast concrete panels and dense blockwork in SE5, often with surface conduit, the pattern behind 12,806 households inside the SE5 neighbourhood, so the fixing that matters in Camberwell is chosen on site — the usual failure here is drilling blind into a panel with reinforcement or a buried cable behind it, as the Camberwell stock goes, which is what a 83% flat share across the ONS neighbourhood covering Camberwell actually produces.
Camberwell sits inside the Congestion Charge zone as well as ULEZ, so both are itemised on the quote rather than absorbed into an hourly rate. What shapes the job more is the neighbourhood itself — georgian Camberwell Grove, the art college and King's College Hospital — which is why a SE5 quote is not a Southwark average.
Getting to the door matters as much as the job: hospital-area restrictions, narrow Georgian streets and steep front steps. Denmark Hill (Overground, Thameslink) is the nearest station, and two to three operatives for a small or mid-size unit, with access equipment booked separately for fascia and signage above ground floor level.
