What we do in Hertsmere
Hertsmere sits just over the border from Barnet, so it is a short run from our North London base. Housing is mostly semi-detached and detached family homes, plus newer flats around Borehamwood and Potters Bar stations — typically uPVC or composite front doors where a euro cylinder drives the whole multipoint lock. That cylinder is what we upgrade.
Most Hertsmere jobs are lock changes after buying a house, landlord changes between tenancies, and homeowners replacing the unrated cylinder a door was supplied with. We fit an Avocet ABS — TS007 3-star and Sold Secure Diamond — sized to the door, with three keys and an itemised invoice.
A common Hertsmere job
Back and side doors on family homes often still have the original basic cylinder even when the front has been upgraded. Each euro cylinder is £149 — worth doing them together.

Why ABS in Hertsmere
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.
