Nunhead SE15 is mainly Victorian and social-housing-led: 58% of homes here are flats and 42% are houses, across 7,127 households (ONS Census 2021).
Because 20% of Nunhead is privately rented and 39% socially rented, a lot of SE15 work is agreed with a landlord or managing agent rather than the person opening the door.
Nunhead substrates run to often with surface conduit — and precast concrete panels and dense blockwork, which is why London Borough of Southwark kerb rules get settled before the van is loaded. Nothing is drilled until the wall has been sounded, because drilling blind into a panel with reinforcement or a buried cable behind it, as the Nunhead stock goes, where 41% owner-occupation means the same home is booked again rather than a new tenant each year is the mistake that costs a SE15 customer twice.
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.
On access, steep hill streets, narrow railway bridges and permit bays near the station — one reason one technician for a standard garden patio or deck; two for a roof terrace or balcony where water has to be carried up by bowser and furniture moved through a lift or stairwell.
