The SE1 stock around Borough Market is Georgian and early Victorian. ONS records 95% flats, 5% houses and 4,532 households in London Bridge and Bermondsey Street.
Private renting sits at 29% and owner-occupation at 21%; the first group books commercial cleaning at short notice, the second plans it.
London Bridge and Bermondsey Street substrates run to often with surface conduit, over precast concrete panels and dense blockwork — the reality on the streets around Borough Market. Nothing is drilled until the wall has been sounded, because in SE1, drilling blind into a panel with reinforcement or a buried cable behind it — which is why London Borough of Southwark kerb rules get settled before the van is loaded is the mistake that costs a SE1 customer twice.
Two streets can behave very differently in London Bridge and Bermondsey Street: the Shard, Borough Market and the Georgian shopfronts of Bermondsey Street. The quote reflects the street the job is actually on. London Bridge and Bermondsey Street 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: market delivery windows before 09:00, railway-arch streets and booked goods lifts in the towers. London Bridge (Northern, Jubilee, National Rail) is the nearest station, and one to four operatives depending on floor area, with a named supervisor and a mobile cover team for sickness.
