What we do in City of London
The City's residential population is small but distinctive — Barbican leaseholders, Smithfield loft owners, and the converted commercial stock around Farringdon and Liverpool Street. Many of these doors are non-standard sizes that need a precisely-cut ABS cylinder rather than an off-the-shelf swap.
We measure on site, cut to size, and fit the same day. Where managing agents require 3-star compliance documentation for the building's insurance schedule, we provide it. Discreet attendance and full insurance for commercial premises.
A common City of London job
Barbican flat doors are a non-standard size — generic cylinders either stick out (making them snap-vulnerable) or sit recessed (jamming the handle). Cut-to-length ABS solves both.

Why ABS — even more relevant in City of London
The London snap-attack method does not discriminate by borough — but the housing stock does affect which doors are most exposed. Whether you have a Victorian timber front door, a uPVC back door, or a composite door on a new-build flat, the euro cylinder is what holds it shut. We replace it with the only cylinder rated 3-star against snap, bump, pick and drill attack independently: Avocet ABS.
What it costs
£149 flat. Cylinder, fitting, three keys, written invoice — all included. No callout fee, no per-minute labour, no upsell on the doorstep. The price you read is the price you pay.
Who we work with in City of London
Three jobs make up almost all our City of London work: landlords doing tenancy-change lock changes, tenants wanting their own keys after moving in, and homeowners upgrading from a generic cylinder to a 3-star ABS. If your job is one of those three, email us with your postcode and door type — we’ll come back within 2 hours with a slot.
