Census 2021 puts Holborn at 3,090 households with a median age of 34.4. The post-war stock is social-housing-led, which is why 5% houses and 95% flats need different handling in WC1.
30% of households rent privately and 18% own, which is why cat flap fitting demand here peaks around tenancy changeovers and completion dates.
Holborn substrates run to precast concrete panels and dense blockwork in Holborn, often with surface conduit — and with 30% of homes here privately rented, it sets the booking date as often as the job does. 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.
On access, inns of Court gate access, weekday loading windows and listed staircases — one reason one fitter for doors and panels; two where a wall tunnel is core-drilled and the debris has to be carried out of a flat. Fitters travelling in use Holborn (Central, Piccadilly).
