Quick Answer
Your van is your livelihood, and having insurance does not mean you are protected. Compliance is not assurance, and that applies to security as much as anything else. The most effective van security layers a Ghost immobiliser (stops keyless relay theft), deadlocks (physical door reinforcement), a Thatcham-approved GPS tracker (recovery), and an interior CCTV camera (evidence and deterrence). No single system is enough. Layer them and thieves move on to an easier target. At Elite Heating and Plumbing, our vans were our livelihood, and security was never optional. I have reviewed all eight systems drawing on my experience running a trades business with multiple vehicles, plus installer specs, Sold Secure ratings, and real feedback from tradespeople. Here is what actually works.

Why Van Theft Costs UK Trades £98M a Year
When I was running Elite Heating and Plumbing, I lost count of the number of times colleagues in the trade had their vans broken into. It was not a question of if, but when. The typical story is always the same: van door hanging open, every power tool gone, a police report that takes hours and replacement tools that take weeks. The average claim is around £3,000 (and that is before the PPE and safety kit you have to replace too), the insurance excess eats into that, and the lost jobs in the meantime cost even more. It is happening to someone in the UK trades every 21 minutes.
Tool theft is not a fringe problem. According to industry data, 44,514 incidents of tool theft were reported to UK police forces in a single year, with £98 million worth of tools stolen from tradespeople. The average individual claim is around £1,500 to £2,200, according to Direct Line 2024 data (which found an average of £1,565 per claim). Ford Transit vans account for more than half of all van thefts nationwide, with over 5,900 stolen in 2024 alone. One in four vans will be targeted at some point.
Let me be blunt: the thieves have upgraded. Relay attacks, CAN bus hacking, OBD port reprogramming. The standard factory alarm and central locking your van came with means almost nothing to a professional gang with £200 of electronic equipment. The security industry has caught up, though. Upgrading your van security is part of a wider digital transformation that forward-thinking trades businesses are embracing. The eight systems here range from £30 to £600. Some are worth every penny. Some are overhyped. Here is the full breakdown.

Ghost Immobiliser: Autowatch Ghost 2 Review
What it is
The Autowatch Ghost 2 is the gold standard of van immobilisation. It connects directly to your van's CAN bus network (the internal communication system all modern vehicles use). When installed, the van will not start until you enter a unique PIN sequence using your existing dashboard buttons (steering wheel, window switches, indicators). There are no visible components, no key fobs, no LED indicators. From the outside, there is nothing to find, cut, or clone.
Why it matters now
Relay attacks and key cloning now account for over 70% of UK vehicle thefts. If thieves boost the signal from your house keys and clone them outside your driveway, they can drive away in seconds. The Ghost 2 defeats this entirely. Even with a cloned key, the van will not start without the PIN. The only way to beat it is physical force, and that defeats the purpose of a quick, quiet theft.
Autowatch Ghost 2
9.5/10Pros
- Defeats relay attacks, key cloning and CAN injection completely
- No visible components, impossible to detect without scanning equipment
- No ongoing subscription fees
- TASSA verified and insurance-approved
- Won't void manufacturer warranty if fitted by approved installer
- Works on virtually every van make and model sold in the UK
Cons
- Professional fitting required (£449–£549 fully fitted)
- If you forget your PIN sequence, you will need breakdown assistance
Typical Cost: £449–£549 Fully Fitted
The Ghost 2 has no subscription fees. You pay once, and that's it for life. Given the average tool claim is £1,500 to £2,200, the maths are obvious. Look for a TASSA-approved installer near you; they carry certification from the Tracking And Aftermarket Security System Association.
Van Deadlocks: Mul-T-Lock and Van Guard Compared
How deadlocks work
A deadlock is a secondary lock fitted to the inside of your van's side or rear doors. It operates independently of the factory central locking. When a thief uses an OBD programmer or relay device to unlock the factory locks, the deadlock stays engaged. You need a separate key to open it. Even if thieves get through the factory security, they still cannot access the load area without physically destroying the door.
The options
The main manufacturers in the UK are Mul-T-Lock, Van Guard, Slam Locks Direct, and Locks 4 Vans. Sold Secure Gold or Diamond rated products are the ones worth buying; these have been tested against real attack methods. Budget deadlocks from unknown brands exist, but they tend to fail under determined attack in 30 seconds or less. A Mul-T-Lock high-security deadlock has been tested to resist attack for 300+ seconds. Choosing the right lock material matters too; our fixings and fasteners guide explains why stainless steel hardware outperforms zinc-plated alternatives in exposed environments.
Deadlocks (Mul-T-Lock / Van Guard)
9.0/10Pros
- Works independently of factory locking. Relay attacks won't open it
- Huge physical deterrence. Visible cylinder on the door
- Can cut van insurance premiums by 5-15%
- Mobile fitting services available nationwide
- Sold Secure Gold/Diamond options available
Cons
- Extra key to carry and remember
- Professional fitting recommended (£150–£250 per door)
- Doesn't protect against window smash-and-grab
Deadlock vs Hook Lock vs Slamlock: What's the Difference?
A deadlock uses a key-operated bolt and works independently of factory locking. A hook lock uses a hooked bolt that grabs onto the door frame; it is stronger than a deadlock against door peel attacks. A slamlock automatically locks when the door closes. For maximum security, many fitters combine a deadlock AND a hook lock on rear doors.
Slamlocks for Trades Vans: Auto-Locking Door Security
A slamlock automatically locks the van door the instant it closes. There is no fumbling with keys or forgetting to lock up. The door locks itself. This is ideal if you are making multiple stops throughout the day: deliveries, house calls, site visits. Every time the door shuts, the van is secured.
Who it is for
Slamlocks are popular with multi-drop delivery drivers and tradespeople who are constantly in and out of their vans. If you leave your van for five minutes to go into a property and forget to lock the side door, a thief can be in and out in under 20 seconds. A slamlock eliminates that risk entirely. The downside is that they are slower to open than a standard lock and you must never leave your key inside the van before the door closes.
Slamlock Pricing: £120–£300 Fitted Per Door
Prices vary by van make and model. Ford Transit, Transit Custom, Vauxhall Vivaro, Renault Trafic and Mercedes Sprinter all have van-specific fitments available. Always use a Sold Secure certified product; cheap imitations can fail the locking mechanism over time.
Van GPS Trackers: VanGuardian vs Thatcham S5
Why tracking matters
A GPS tracker tells you where your van is at all times. If it is stolen, you have real-time location data to give to the police. Thatcham Cat 6/7 approved trackers are linked to monitoring centres that will contact police on your behalf. Tracked vehicles have a recovery rate of around 90%, compared to under 20% for untracked ones.
VanGuardian and other options
VanGuardian offers a GPS tracking device at £99+VAT with no monthly subscription, an unusual and attractive proposition in a market full of ongoing fees. It also doubles as a motion-sensitive alarm that activates before entry is made, removing the thief's advantage of anonymity. For Thatcham-approved S5 tracking (the standard insurers prefer), expect to pay £300–£500 for hardware plus a £10–£20/month monitoring subscription. If you are already running fleet tracking or route management software, our comparison of van management platforms covers how GPS security integrates with broader fleet operations.
VanGuardian GPS Tracker
8.0/10Pros
- £99+VAT with no ongoing monthly fees
- Self-installation, takes minutes
- Motion detection alarm activates before entry (not after)
Cons
- Not Thatcham approved, so insurers may not recognise it
- No 24/7 monitoring centre backing
- Relies on SIM connectivity; can be jammed in theory
- Battery-powered, needs recharging every few weeks depending on use
Interior Van CCTV: AI Cameras for Van Security
An interior van camera records the inside of your van continuously. Motion detection triggers instant alerts to your phone when movement is detected while the van is locked. Some systems send a 30-second clip of any detected incident straight to your phone. AI-powered versions go further. They can recognise faces, track movement patterns, and distinguish between genuine intrusion attempts and animals or passing headlights.
AI CCTV: The Next Level
AI-powered van CCTV (companies like Catch a Thief UK) use machine learning to filter out false alarms and flag real threats. AI is transforming many trades workflows beyond security; our AI tools guide covers what is worth using and what is not. These systems can detect a person approaching your van at 2am and send a live alert before they have even tried to open a door. Some include number plate recognition that logs every vehicle that passes your parked van overnight. Costs are higher, typically £400–£800 for hardware plus a subscription, but for high-value tool setups, the investment is justified.
OBD Port Blockers: Cheap Protection Against Key Cloning
The £30 layer most people skip
Your OBD (On-Board Diagnostics) port is a small socket usually located under the dashboard. It is how mechanics plug in diagnostic equipment. It is also how thieves reprogram a van's ECU to create a blank key in under 60 seconds. An OBD port blocker is a lockable cover that physically prevents access to the port.
Is it worth it?
At £30–£80 fitted, an OBD port blocker is one of the cheapest additional layers you can add. It specifically protects against OBD-based key programming attacks, which are now routine on Ford Transit and Vauxhall Vivaro models. It won't stop everything, but combined with a Ghost immobiliser (which renders OBD reprogramming useless anyway), it adds another step thieves have to defeat.
Legislation Update: 2025 Ban on Theft Devices
In February 2025, new UK legislation made it illegal to possess or distribute electronic devices used to steal vehicles, including signal jammers, relay gadgets, and OBD programming tools not used for legitimate vehicle servicing. This is a useful signal but should not encourage complacency. The devices are still widely available, and enforcement is difficult.
Having insurance is not the same as being protected. Insurance pays out after the damage is done. A layered security system stops the damage happening in the first place. One is paperwork. The other is risk management. Do the work upfront.
Thatcham Cat 1 Alarm: Is It Worth the Cost?
How it differs from your factory alarm
A Thatcham Category 1 alarm is the highest standard of factory-equivalent aftermarket alarm. It includes a full immobiliser and alarm system with a siren, door and bonnet sensors, and movement detection. Unlike factory alarms, it cannot be defeated by relay attacks or key cloning because it uses its own independent authentication. Thatcham certification means insurers will typically reduce premiums.
Cost and fitting
A fitted Thatcham Cat 1 alarm typically costs £300–£600, depending on your van model and the level of sensors included. Many also include remote monitoring and phone alerts. If you are buying a Ghost 2 immobiliser from an approved installer, ask about combining it with a Thatcham alarm. Many installers offer discounted packages.
Insurance Implications
Fitting a Thatcham Cat 1 alarm, a Thatcham S5 tracker, or a Ghost 2 immobiliser can each reduce your van insurance premium by 5-15%. On a premium of £1,200/year, that is £60-£180 off annually. The security devices often pay for themselves within two to four years on premium savings alone, before you factor in the value of what they protect. If you are a CIS-registered subcontractor, claim the full cost as a business expense. Trades that require registration, such as those on the Gas Safe Register, carry especially expensive specialist tools that make the investment even more worthwhile.
Steering Wheel Locks: Milenco vs Disklok
A steering wheel lock is the most visible deterrent available. It is a physical bar that clamps onto the steering wheel and prevents it from being turned. Any thief who gets into the van, even if they bypass everything else, cannot drive it away if the steering is locked. The psychological impact should not be underestimated. Most thieves operate on speed and stealth. A visible yellow steering lock tells them this van will take time and noise. They move on.
Best options
The Milenco High Security Steering Wheel Lock (from £65) is Sold Secure Gold rated and resists 300 seconds of attack. It is the best value option for everyday use. The Disklok (£170–£295) covers the entire wheel and is much harder to cut, but it is heavy and cumbersome to use daily. For tradespeople using the van every day, the Milenco is the practical choice. The Disklok is better for longer-term parking or high-risk areas.
Van Security Layering: My Recommended Setup
No single security system will stop a determined, professional gang. But the statistics are clear: most van thieves are opportunists, not professionals. They target the van that is quickest and easiest. Add enough layers and you become too much trouble. Here is the setup I recommend after researching everything above.
| System | Cost (Fitted) | Subscription | Defeats | Rating |
|---|---|---|---|---|
| Ghost Immobiliser | £449–£549 | None | Relay, key clone, CAN injection | 9.5/10 |
| Deadlocks | £150–£250/door | None | OBD unlock, relay unlock | 9.0/10 |
| Thatcham GPS Tracker | £300–£500 | £10–£20/month | Recovery after theft | 8.5/10 |
| Slamlocks | £120–£300/door | None | Opportunistic grab, unlocked door | 8.0/10 |
| VanGuardian GPS | £99+VAT | None | Tracking + motion alarm | 8.0/10 |
| Interior CCTV | £100–£800 | £5–£15/month | Evidence gathering, deterrence | 7.5/10 |
| Steering Wheel Lock | £60–£295 | None | Drive-away after entry | 7.0/10 |
| OBD Port Blocker | £30–£80 | None | OBD key programming | 6.5/10 |
You would not leave an electrical installation half-finished with live cables exposed. So why would you leave £3,000 worth of tools in a van with nothing but a factory lock between them and the street?
Minimum Recommended Setup: £700 to £900 All-In
Ghost 2 immobiliser (£499) + two rear deadlocks (£200) + OBD port blocker (£50) + steering wheel lock (£65). This combination defeats the three most common attack methods: relay/keyless theft, OBD reprogramming, and opportunistic door entry. Add a GPS tracker if your van carries over £2,000 in tools. High-value kit like a drone survey setup or specialist test equipment justifies the extra spend on tracking.
My Verdict
After reviewing all eight systems, the Ghost 2 immobiliser is the single most effective investment you can make. It defeats the three most common modern theft methods in one device. Pair it with deadlocks on the rear and side doors and you have stopped 90% of what professional thieves will attempt. Add a GPS tracker for recovery and a steering wheel lock for visual deterrence, and your van becomes more trouble than it is worth to almost anyone.
Best overall: Autowatch Ghost 2 immobiliser (£449–£549 fitted, no ongoing fees)
Best budget layer: Steering wheel lock + OBD blocker for under £150
Best for recovery: Thatcham S5 GPS tracker with monitoring centre
Recommended minimum: Ghost 2 + deadlocks + GPS tracker

In theory, yes. Thatcham S5 trackers detect jamming attempts and alert the monitoring centre automatically, which is why insurers prefer them. Budget trackers like VanGuardian are more vulnerable to jamming, but most opportunistic thieves are not carrying signal jammers. They are carrying a screwdriver and a relay box. If you are in a high-risk area or carrying over £5,000 in tools, spend the extra on Thatcham S5.
Yes, typically 5-15% off your premium for Sold Secure Gold or Diamond rated products. Tell your insurer before renewal, not after. And claim the cost as a business expense.
Ford Transit. Not even close. Over 5,900 stolen in 2024, more than half of all van thefts nationwide. If you drive a Transit with factory security only, you are making it easy for them.
Yes. Every night. No security system is a substitute for an empty van. Take the power tools and anything over £100 into the house or a locked garage. Leaving a Hilti drill and a Megger in a Transit overnight is asking for trouble, no matter how many deadlocks you have. Security is your backstop for the nights you cannot unload, not an excuse to leave everything in.
