Off-licences face a brutal and growing threat. They hold three things criminals actively target: cash in the till, expensive stock on shelves, and often a single entry point that’s easy to breach quickly. Robberies and ram-raids on off-licences are not isolated incidents. They represent a serious problem for store owners, staff safety, and the communities these businesses serve.
The Association of Convenience Stores recorded 59,000 violent incidents across the convenience sector in the last year. This includes 22,478 robberies of business premises—a 66% increase year-on-year. Two-thirds target cash or high-value goods. Off-licences are easy targets because they stock spirits and premium brands worth taking quickly.
Why Off-Licences Are Under Attack
Robberies are effective for offenders because the economics make sense. A till holds accessible cash. Shelves are stocked with spirits and premium products that have high resale value. The store layout is familiar to local offenders from previous visits. Armed robbery follows a predictable pattern: gain entry fast, threaten staff verbally or with a weapon, grab items from the till or shelves, and leave before police arrive. Staff compliance is immediate because the threat of violence is immediate and credible.
Ram-raids follow a different but equally effective model. A vehicle smashes through the frontage, typically in the early morning hours when staff presence is minimal or the store is closed. The offender targets high-value stock—premium bottles of spirits and wine—loads quickly, and departs before any meaningful response is possible. Police response times, even in urban areas, are measured in minutes. The offender is often gone in under five minutes.
22,478 robberies of business premises in 2024–25: a 66% increase year-on-year. Off-licences are frequent targets because they hold cash and high-value stock.
The Limits of Physical Security Alone
Shutters and metal grilles do provide a delay. But the delay is shorter than many store owners believe. A determined attacker armed with a hammer, crowbar, or pry bar can compromise a typical metal grille in two to three minutes. A vehicle moving at speed breaches a standard doorframe in seconds. During these moments—the only moments when staff might escape or lock themselves into a safe area—staff are exposed to violence and at serious personal risk.
The fundamental problem is that physical barriers only slow attacks; they do not stop them. After the barrier is breached, the attacker still reaches the tills or shelves. The robbery still happens. Stock is still taken. Staff are still in danger. The front of the store is damaged and requires expensive repairs. The attack succeeds—just with a short delay.
How Security Fog Changes the Equation
Security fog systems like the UNIK fog system operate on a different principle entirely. They deploy within seconds of an alarm trigger. When an attacker breaches a door or window, the fog generator activates automatically and fills the entire sales floor with a dense, opaque mist. Within five seconds, visibility is reduced to near-zero. An attacker cannot navigate safely.
The effect is immediate. Criminals cannot see the tills. They cannot locate stock. They cannot identify staff or customers. The store becomes a liability, not a prize. Most attackers leave immediately. Those who stay move blind and slowly—easy targets for police.
The fog itself is safe. It’s non-toxic and certified by Eurofins for safety to humans and animals. In an off-licence environment, it is also tested and certified for food contact under Regulation (CE) No. 1935/2004. This means it is completely safe to deploy around all beverages, wines, spirits, and food products. It does not leave stains, residue, or damage to bottles.
Speed and Deterrence in One Layer
Speed is the key advantage. A traditional alarm calls police. But fog stops the attack now. The attacker can’t finish the crime. Stock stays on the shelves. Tills stay secure. Staff stay out of harm’s way.
Word spreads fast in criminal networks. An off-licence with fog becomes a bad target. Attacks move to easier targets. This happens in real places—across 80+ countries, thousands of sites use foam to stop theft.
Integration with Existing Alarms
Fog systems work with your existing alarm. Whether you have a hardwired system, Ajax, or another provider, fog integrates easily. When the alarm triggers, fog deploys instantly.
Systems meeting EN 50131-8:2019 support remote monitoring. You get alerts in real time. Fog works even if power fails or the internet goes down.
For larger off-licences, you can cover multiple zones: stockrooms, offices, and the sales floor. Fog deploys where you need it most.
The Evidence: Fog Plus Alarm
Here’s the key number: 97% of thefts are avoided with a fogging system AND an alarm, compared with 17% with an alarm only. That’s a Density® manufacturer figure, tested in high-crime retail. An alarm is a warning. Fog is an active barrier that stops the crime.
For your off-licence, this is real: you stop the attacker before they reach the stock. Staff don’t face an armed raider. Tills stay secure. Your store and your reputation stay intact.
Planning a Fog Installation for Your Off-Licence
Most standalone and small-chain off-licences require modest generator capacity. The UNIK system is specifically designed for smaller retail spaces. It provides instant fog deployment, generates zero heat, and offers up to six months of battery autonomy—meaning protection continues even during a mains power failure. The system covers spaces up to 600 cubic metres, which is sufficient for most conventional off-licence layouts. Installation is straightforward: the generator is mounted discreetly near the till area or in a stockroom, and the deployment trigger is integrated directly into your existing alarm panel. For a full assessment of your specific premises and security requirements, see the Off-Licences security guide.
A comprehensive security strategy combines your existing physical measures with active fog protection. Shutters and grilles slow the attacker and buy critical seconds. Security fog then deploys and renders the premises worthless to them. When layered together, these create a system that is genuinely difficult to breach and even less rewarding when breached. The combination is far more effective than either layer alone.

Frequently asked questions
Will the fog damage bottles or stock in an off-licence?
No. The fog is safe around food and drink. It’s certified under Regulation (CE) No. 1935/2004. It won’t stain or damage bottles or stock.
How quickly does the fog deploy?
Fog starts within seconds of an alarm trigger. It fills the sales floor in about five seconds. Attackers can’t see at all.
Can the fog be triggered manually or only by the alarm?
The alarm triggers the fog. Staff can also trigger it manually in an emergency. It won’t go off by accident.
Will a fogging system work if the power goes out?
Yes. Fog systems have battery backup. The UNIK system runs for six months on battery alone. Power failure doesn’t affect protection.
How much does a security fog system cost to install and maintain?
Contact the Density team for a free survey and quote. Maintenance is minimal, and the cost is lower than most physical security upgrades or CCTV expansion.
Off-licence robbery and ram-raids are preventable. Security fog stops fast attacks, protects staff, and makes your store a poor target. Contact Density to arrange a site survey and protection plan for your store.
