Holborn WC1 is post-war and social-housing-led: 95% of homes here are flats and 5% are houses, across 3,090 households (ONS Census 2021).
The social-housing-led mix here (18% owned, 30% privately rented) means a WC1 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Holborn substrates run to precast concrete panels and dense blockwork in WC1, often with surface conduit, a median age of 34 in this neighbourhood shapes what gets ordered here. Nothing is drilled until the wall has been sounded, because drilling blind into a panel with reinforcement or a buried cable behind it, as the Holborn stock goes, which is what a 95% flat share across the ONS neighbourhood covering Holborn actually produces is the mistake that costs a WC1 customer twice.
Legal London — the Inns of Court, Lincoln's Inn Fields and Sicilian Avenue. That character decides the practical detail of shed assembly here far more than the borough boundary does. Holborn 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, inns of Court gate access, weekday loading windows and listed staircases — one reason one fitter for a small shed on a ready base; two for anything over 8x6ft or where roof panels need lifting together. Fitters travelling in use Holborn (Central, Piccadilly).
