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 buildings around Farringdon and Liverpool Street. Doors in converted buildings are often non-standard thicknesses, which is why we measure before fitting rather than guessing.
Where a managing agent needs evidence of what was fitted, the itemised invoice names the cylinder and its ratings. Our service is residential: flat and house doors, not commercial master-key systems.
A common City of London job
A cylinder that is too long sticks out and is easier to snap; one that is too short can jam the handle. Measured, correctly sized ABS avoids both.

Why ABS in City of London
Snap attacks do not discriminate by postcode, but the housing stock decides which doors are exposed. Whether you have a Victorian timber 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 an Avocet ABS — rated TS007 3-star on its own, so the door meets the standard whatever handle is fitted. Not sure what the stars mean? Read TS007 3-star explained.
What it costs
£149 flat for a planned booking. Cylinder, fitting, three keys, written invoice — all included. No callout fee, no per-minute labour, no upsell on the doorstep. For how that compares with typical London prices, see our lock change cost guide.
