In Clerkenwell (EC1) the split is 94% flats to 6% houses over 5,170 households, and the stock is Georgian and early Victorian.
The renter-heavy mix here (25% owned, 36% privately rented) means a EC1 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Clerkenwell substrates run to often with surface conduit — and precast concrete panels and dense blockwork, measured on the walk in from Farringdon (Elizabeth line, Circle, Thameslink), with Barbican just east rather than assumed from a map. Nothing is drilled until the wall has been sounded, because Clerkenwell gives us drilling blind into a panel with reinforcement or a buried cable behind it, which is what a 94% flat share across the ONS neighbourhood covering Clerkenwell actually produces is the mistake that costs a EC1 customer twice.
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.
Getting to the door matters as much as the job: narrow one-way streets, seven-day controlled bays and warehouse lofts up several flights of stairs. Farringdon (Elizabeth line, Circle, Thameslink), with Barbican just east is the nearest station, and one fitter for bistro sets, parasols and BBQs; two for corner sofa sets, large dining sets and shed bases.
