In Brockley (SE4) the split is 70% flats to 30% houses over 6,905 households, and the stock is mainly Victorian.
Because 30% of Brockley is privately rented and 31% socially rented, a lot of SE4 work is agreed with a landlord or managing agent rather than the person opening the door.
Brockley substrates run to precast concrete panels and dense blockwork in Brockley, often with surface conduit, and with 30% one-person households in Brockley, one adult is usually the only pair of hands on site. 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 Brockley stock goes, where 39% owner-occupation means the same home is booked again rather than a new tenant each year is the mistake that costs a SE4 customer twice.
Brockley 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 — conservation-area streets of large Victorian villas and the Hilly Fields view — which is why a SE4 quote is not a Lewisham average.
Steep hills, long front paths and conversion flats up two or three flights. Nearest station is Brockley (Overground), and one technician and a van-mounted hot-water pressure washer for most driveways; two on larger block-paving jobs where re-sanding is included, since brushing sand in is a second task run alongside the wash.
