In Brixton (SW9) the split is 80% flats to 20% houses over 16,254 households, and the stock is mainly Victorian.
The social-housing-led mix here (31% owned, 30% privately rented) means a SW9 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Expect often with surface conduit — and precast concrete panels and dense blockwork, measured on the walk in from Brixton (Victoria, National Rail) rather than assumed from a map behind the plaster in SW9. That is why fixings are picked in the room rather than off a van shelf, and why Brixton gives us drilling blind into a panel with reinforcement or a buried cable behind it, where 31% owner-occupation means the same home is booked again rather than a new tenant each year is the fault we are called back to undo.
Brixton 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 — market arcades, the Academy and one of the most culturally significant high streets in London — which is why a SW9 quote is not a Lambeth average.
On access, market and nightlife congestion, red routes on the A23 and permit-only side streets — one reason 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.
