In Canada Water (SE16) the split is 90% flats to 10% houses over 4,483 households, and the stock is post-war.
The social-housing-led mix here (20% owned, 33% privately rented) means a SE16 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Expect precast concrete panels and dense blockwork in Canada Water, often with surface conduit, the pattern behind 4,483 households inside the SE16 neighbourhood behind the plaster in SE16. That is why fixings are picked in the room rather than off a van shelf, and why Canada Water gives us drilling blind into a panel with reinforcement or a buried cable behind it, where 20% 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.
Canada Water 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 — dock, library and the biggest regeneration site in south-east London — which is why a SE16 quote is not a Southwark average.
On access, construction diversions, estate loading bays and mandatory lift booking in new blocks — one reason 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.
