In Nunhead (SE15) the split is 58% flats to 42% houses over 7,127 households, and the stock is mainly Victorian.
The social-housing-led mix here (41% owned, 20% privately rented) means a SE15 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Walls are precast concrete panels and dense blockwork in SE15, often with surface conduit, measured on the walk in from Nunhead (Southeastern) rather than assumed from a map, so the fixing that matters in Nunhead is chosen on site — the usual failure here is drilling blind into a panel with reinforcement or a buried cable behind it, as the Nunhead stock goes, a median age of 35 in this neighbourhood shapes what gets ordered here.
Nunhead 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 — cemetery, hill views and a quiet village green between Peckham and Brockley — which is why a SE15 quote is not a Southwark average.
Steep hill streets, narrow railway bridges and permit bays near the station. Nearest station is Nunhead (Southeastern), and one technician with a portable extraction machine and air mover on a single household booking; two technicians on HMO, student accommodation and serviced-apartment rounds where six or more mattresses are cleaned in a day.
