Walk Elephant and Castle from Elephant Park outwards and the Georgian and early Victorian pattern is obvious: 96% of the 3,233 households in SE17 live in flats, 4% in houses.
48% of households rent privately and 20% own, which is why patio and decking cleaning demand here peaks around tenancy changeovers and completion dates.
Elephant and Castle substrates run to often with surface conduit — and precast concrete panels and dense blockwork — which is what a 96% flat share across the ONS neighbourhood covering Elephant and Castle actually produces. Nothing is drilled until the wall has been sounded, because in SE17, drilling blind into a panel with reinforcement or a buried cable behind it — measured on the walk in from Elephant & Castle (Northern, Bakerloo, Thameslink) rather than assumed from a map is the mistake that costs a SE17 customer twice.
Two streets can behave very differently in Elephant and Castle: rebuilt junction of new towers, the university campus and the remains of the Heygate. The quote reflects the street the job is actually on. Elephant and Castle sits inside the Congestion Charge zone as well as ULEZ, so both are itemised on the quote rather than absorbed into an hourly rate.
Getting to the door matters as much as the job: junction red routes, construction diversions and strict loading-dock booking in new towers. Elephant & Castle (Northern, Bakerloo, Thameslink) is the nearest station, and 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.
