The WC1 stock around Lincoln's Inn Fields is post-war. ONS records 95% flats, 5% houses and 3,090 households in Holborn.
Owner-occupation runs at 18% in Holborn, so alongside the 30% rental churn there is steady planned work — refurbishments, downsizes and probate clearances booked weeks ahead.
Holborn substrates run to often with surface conduit, over precast concrete panels and dense blockwork — the reality on the streets around Lincoln's Inn Fields. Nothing is drilled until the wall has been sounded, because in WC1, drilling blind into a panel with reinforcement or a buried cable behind it — measured on the walk in from Holborn (Central, Piccadilly) rather than assumed from a map is the mistake that costs a WC1 customer twice.
Two streets can behave very differently in Holborn: legal London — the Inns of Court, Lincoln's Inn Fields and Sicilian Avenue. The quote reflects the street the job is actually on. 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.
Getting to the door matters as much as the job: inns of Court gate access, weekday loading windows and listed staircases.
