In Clerkenwell (EC1) the split is 94% flats to 6% houses over 5,170 households, and the stock is Georgian and early Victorian.
Because 36% of Clerkenwell is privately rented and 39% socially rented, a lot of EC1 work is agreed with a landlord or managing agent rather than the person opening the door.
Expect often with surface conduit, over precast concrete panels and dense blockwork, which is why City of London Corporation kerb rules get settled before the van is loaded behind the plaster in EC1. That is why fixings are picked in the room rather than off a van shelf, and why Clerkenwell gives us drilling blind into a panel with reinforcement or a buried cable behind it, and with 36% of homes here privately rented, it sets the booking date as often as the job does is the fault we are called back to undo.
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. What shapes the job more is the neighbourhood itself — design studios, Italian delis and Georgian squares on the City's north-west edge — which is why a EC1 quote is not a City of London average.
On access, narrow one-way streets, seven-day controlled bays and warehouse lofts up several flights of stairs — one reason one technician with a van-mounted dip tank; two where a barbecue has to be carried through a flat to reach a terrace. Fitters travelling in use Farringdon (Elizabeth line, Circle, Thameslink), with Barbican just east.
