Professional Security Upgrade Services
Here’s a stat that should bother you: 1 in 5 of our Islington lockout customers end up upgrading their locks on the same visit. They call us because they’re locked out, and once we’re inside and they see the state of what was supposedly protecting their home, they upgrade on the spot. That tells you everything about the gap between what people think their locks are doing and what they’re actually doing.

We’ve handled security upgrades across Islington that range from a single BS3621 5-lever deadlock on a Victorian front door to comprehensive multi-lock hardening jobs. The biggest: four euro deadcases with bullet locks fitted to entrance and fire exit doors at a property in N1 8 — all in one visit. A creative venue near Old Street needed three deadlocks, a euro cylinder, roller shutter bullet locks, and code lock servicing across three visits. Council estates across N1 account for a significant share of our upgrade work — deadlock upgrades on flat front doors are one of the most common jobs we do on estates. Security gates are a recurring theme too — several Islington properties have internal gates needing BS-rated sash locks or deadlocks.
The most common upgrade we do in Islington? Replacing 3-lever mortice locks with 5-lever BS3621 insurance-compliant deadlocks. Your insurer almost certainly requires BS3621 on every external door. If you’ve got an old 3-lever lock — and most Victorian conversions in N1 still do — your insurance could be void and you wouldn’t know it until you tried to claim. We’ve replaced Union 5-lever BS sash locks, fitted ERA nightlatches to BS standard, upgraded 3G114 lever packs in existing deadlocks, and installed high-security cylinders where maximum pick resistance is needed. Every job comes with a locksmith certificate for your insurer.
Multipoint locking systems are the other big upgrade category. UPVC and composite front doors across Islington develop gearbox failures, keeps shift out of alignment, and the whole mechanism seizes. We’ve replaced complete multipoint systems, swapped out failed gearboxes, and adjusted centre keeps that have shifted as buildings settle. If your front door won’t lock properly from the inside, the gearbox is usually the culprit — and replacing it before it fails completely saves you an emergency call-out later.
Post-burglary upgrades are a significant part of what we do, and we don’t sugarcoat it. If someone has kicked your door in, a like-for-like replacement of whatever was there before is not a security upgrade — it’s putting the same weakness back. We fit euro deadcases with bullet locks to reinforce against forced entry, upgrade cylinders to anti-snap specifications, and install high-security hardware where it’s needed. The goal is to make your property harder to get into than the one next door. No call-out fee, no sales pitch — just honest advice on what actually needs upgrading.
Serving Islington
London Borough of Islington
Islington’s property stock creates two distinct security upgrade profiles, and we see both every week.
The Victorian and Edwardian conversions — particularly across Barnsbury, Canonbury, and the streets around Angel — still run on rim cylinders and traditional nightlatches.
These are the properties where we most often find 3-lever locks that haven’t been changed since the house was converted into flats decades ago.
They need BS3621 5-lever deadlocks, upgraded nightlatches, and often a complete re-securing of the front entrance door.
Then there are the purpose-built blocks and council estates across N1 — where euro cylinders and multipoint locking systems are standard.
These properties need anti-snap euro cylinder upgrades, gearbox replacements when the multipoint mechanism fails, and bullet locks on doors that face communal hallways.
We’ve completed 132 jobs across N1 and N7 in the past year.
We know which streets have which locks, which buildings have recurring problems, and which door types need which locks.
Our N1 office means we’re not guessing — we already know the building before we arrive.
