In Barbican (EC2) the split is 98% flats to 2% houses over 4,914 households, and the stock is post-war.
The renter-heavy mix here (37% owned, 48% privately rented) means a EC2 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Barbican substrates run to with metal stud partitions between rooms — and dot-and-dab plasterboard over blockwork, which is why City of London Corporation kerb rules get settled before the van is loaded. Nothing is drilled until the wall has been sounded, because short screws that grip only the board and slowly lever it off the dabs, as the Barbican stock goes, which is what a 98% flat share across the ONS neighbourhood covering Barbican actually produces is the mistake that costs a EC2 customer twice.
Barbican 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 — brutalist estate of towers and terrace blocks around lakes and an arts centre, quiet at weekends — which is why a EC2 quote is not a City of London average.
Estate loading bays must be booked with the car park office; goods lifts are shared and time-limited. Nearest station is Barbican (Circle, Metropolitan, Hammersmith & City), and two operatives as standard, one in the loft and one on the ladder and ground floor, which is how a loft clear stays safe rather than a one-person job with a rope and a prayer.
