Walk Clerkenwell from The Charterhouse and Exmouth Market outwards and the Georgian and early Victorian pattern is obvious: 94% of the 5,170 households in EC1 live in flats, 6% in houses.
Private renting sits at 36% and owner-occupation at 25%; the first group books construction site clearance at short notice, the second plans it.
Walls are often with surface conduit, over precast concrete panels and dense blockwork — the reality on the streets around The Charterhouse and Exmouth Market, so the fixing that matters in Clerkenwell is chosen on site — the usual failure here is in EC1, drilling blind into a panel with reinforcement or a buried cable behind it — with 39% social-rented stock locally, block access is agreed with the estate office first.
Two streets can behave very differently in Clerkenwell: design studios, Italian delis and Georgian squares on the City's north-west edge. The quote reflects the street the job is actually on. Clerkenwell sits inside the Congestion Charge zone as well as ULEZ, so both are itemised on the quote rather than absorbed into an hourly rate.
On access, narrow one-way streets, seven-day controlled bays and warehouse lofts up several flights of stairs — one reason two operatives with a 3.5t tipper as standard, scaling to four operatives and a 7.5t vehicle on strip-outs or where the waste has to be barrowed a long way to the frontage.
