Why Insurance Companies Require Thatcham Approved Trackers

If you've recently bought a high-value car, a performance model or a vehicle with a patchy theft record, there's a good chance your insurer has asked you to fit a Thatcham approved tracker. For many drivers, it's the first time they've heard the term, and the request can feel like one more hoop to jump through before the policy goes live.

There's solid reasoning behind it, though. Insurers aren't asking for a tracker at random. They want a device that has been independently tested, professionally fitted and monitored around the clock, because that combination changes the odds of getting a stolen vehicle back. Below, we explain what Thatcham approval really means, why insurers insist on it, and how it can work in your favour.

What Is Thatcham Research?

Thatcham Research is the UK motor insurance industry's independent research centre. Founded in 1969 and funded by insurers, it tests vehicle safety and security systems against rigorous standards. When a tracker carries Thatcham approval, it means the device has passed a demanding assessment covering accuracy, tamper resistance, reliability and the monitoring service behind it.

For vehicle trackers, the two categories insurers ask for most often are:

• Thatcham S7: a stolen vehicle tracking system linked to a 24/7 monitoring centre, with location data shared with the police to aid recovery.
• Thatcham S5: everything in S7, plus Automatic Driver Recognition. The vehicle knows whether an authorised driver is present, usually through a small tag or fob, and the control room is alerted if it moves without one.

Some S5 systems go a step further by adding immobilisation, so the engine won't start at all without the tag. GPSBob refers to this as its S5 Plus.

Reasons Insurers Require Thatcham Approved Trackers

1. Independent Testing Removes the Guesswork

The market is full of GPS trackers, and the quality varies hugely. Some are excellent. Others lose signal, drain batteries or can be found and disabled in seconds. An insurer can't test every device on the market, so it relies on Thatcham to do that work.

Approval gives underwriters confidence that the tracker in your car meets a known, consistent standard. It's the same reason insurers ask for approved alarms and immobilisers. A recognised benchmark lets them price risk accurately.

2. 24/7 Monitoring Means Someone Always Responds

A standard GPS tracker shows you where your car is, but only if you happen to check. If it's stolen at 3am while you're asleep, the thieves may have hours of head start before you notice.

Thatcham approved trackers are connected to an accredited Secure Operating Centre that monitors the system around the clock. When a theft alert is triggered, trained operators start working on it straight away. From an insurer's point of view, that speed is everything, because vehicles recovered quickly are far less likely to be damaged, stripped or shipped abroad.

3. Priority Police Response Improves Recovery Rates

Monitoring centres working with Thatcham approved systems have established links with UK police forces. When a theft is verified, the vehicle can receive a priority response, with live location data passed directly to officers.

Every recovered vehicle is a claim the insurer doesn't have to pay in full. Across thousands of policies, better recovery rates mean lower losses, which is exactly why insurers are keen to see approved tracking fitted to the vehicles they consider most at risk.

4. Driver Recognition Beats Keyless and Key Theft

Modern car crime has moved on. Relay attacks, key cloning and keyless entry exploits mean that thieves often drive off without breaking a window or setting off an alarm. To the car, it looks like the owner has simply unlocked it.

That's where S5 technology earns its place. Because the tracker checks for an authorised driver tag, a vehicle moving without one is flagged immediately, regardless of how the thieves got in. GPSBob's Mongoose S5 uses a fob with Time-Based One-Time Password technology, similar to the security used by banks, making the tag itself extremely difficult to clone.

Add immobilisation and the theft stops before it starts. With an S5 Plus system, no tag means no start, even if the thieves have a working copy of the key.

5. Approved Trackers Are Built to Resist Tampering

Experienced thieves know what to look for. A tracker that's easy to find or disconnect offers very little protection. Thatcham approved systems are designed with features such as backup batteries and tamper alerts, so disconnecting the power or interfering with the unit triggers a warning rather than silencing the device.

For insurers, that resilience is the difference between a tracker that looks good on paper and one that genuinely helps recover stolen vehicles.

6. Professional Installation Guarantees It Works

A tracker is only as good as its fitting. Poorly installed units can fail without anyone realising, or be placed somewhere obvious. Thatcham approved trackers must be fitted by approved installers, who issue a certificate confirming the system is installed correctly and active.

That certificate gives your insurer proof that the condition of cover has been met. GPSBob offers free professional installation on its insurance approved trackers anywhere in the UK, with engineers coming to your home or workplace.

7. High-Risk Vehicles Need Higher Protection

Insurers track theft data closely. Certain makes and models are targeted far more often than others, particularly premium SUVs, performance cars and vehicles with known keyless vulnerabilities. For these, a tracker requirement is often non-negotiable.

The same applies to high-value vehicles in general. The more a car is worth, the bigger the potential claim, and the more an insurer wants reassurance that a stolen vehicle can be found quickly.

Can a Thatcham Tracker Lower Your Premium?

Very often, yes. Because approved trackers reduce the risk of total loss, many insurers reward them with a lower premium, with savings of up to 20% possible depending on the provider and vehicle. Where a tracker is a condition of cover, fitting one may be the only way to secure a policy at all.

Standard GPS trackers are rarely recognised for discounts. They can still be useful for keeping an eye on a vehicle, but they don't carry the testing, monitoring or police links insurers are looking for.

S5 or S7: Which Will Your Insurer Ask For?

Your insurer will usually specify the category it needs, so always check your policy documents or ask directly before buying.

As a rule of thumb, S7 is the most common requirement and a cost-effective way to meet it. S5 is typically requested for higher-value or higher-risk vehicles, especially those vulnerable to keyless theft. If you want the strongest protection available, an S5 system with immobilisation adds a final barrier on top.

Meet Your Insurer's Requirements With Confidence

Insurers require Thatcham approved trackers because they work. Independent testing, round-the-clock monitoring, priority police response and professional fitting all combine to give stolen vehicles a far better chance of coming home.

If your insurer has asked for an approved tracker, or you simply want the best protection for a valuable car, GPSBob's insurance approved range covers every option. 

Frequently Asked Questions

Is Thatcham a government organisation?

No. Thatcham Research is an independent, not-for-profit research centre funded by UK motor insurers. It sets security and safety standards that insurers use to assess vehicle risk.

How can I check a tracker is genuinely Thatcham approved?

Ask the supplier for the product's Thatcham category and check it against Thatcham Research's published list of approved systems. After fitting, you should also receive an installation certificate.

What happens if my tracker subscription lapses?

If the monitoring subscription lapses, the 24/7 control room stops monitoring your vehicle. This can breach your insurer's requirements and may affect a theft claim, so keep it active.

Do Thatcham approved trackers work in Europe?

Most Thatcham approved trackers include European coverage, allowing the monitoring centre to track a stolen vehicle abroad and work with overseas police. Confirm coverage with your provider before travelling.

Can I move my tracker to a new car?

Often, yes. Many approved trackers can be removed and refitted to a replacement vehicle by an approved installer, who issues a new certificate. Fees and eligibility vary by provider.

How to Protect Your Fleet Vehicles Against Theft: Expert Strategies

Losing a vehicle is bad enough for a private driver. For a business, it's worse. A stolen van means missed jobs, lost tools, disappointed customers and an insurance claim that can push your premium up for years. Multiply that risk across a fleet and vehicle theft becomes one of the most serious operational threats a company can face.

Commercial vehicles are attractive targets. Vans often carry expensive tools and stock, they're parked in predictable places, and they're easy to sell on or break for parts. Thieves are well organised and increasingly use technology to beat factory security.

The good news is that a layered approach makes your fleet a far harder target. These expert strategies will help you protect your vehicles, your equipment and your bottom line.

1. Fit GPS Trackers to Every Vehicle

If there's one step that gives you the best chance of getting a stolen vehicle back, it's GPS tracking. Without it, recovery relies on luck and a registration plate that may already have been changed. With it, you and the police have a live location to work from.

The right tracker depends on the vehicle:

• Hardwired trackers connect to the vehicle's power supply and are ideal for vans, trucks and HGVs. GPSBob's Two-Wire 4G GPS Vehicle Tracker is compact and easy to conceal, and its simple two-wire connection makes fitting quick.
• Plug-in OBD trackers fit straight into the vehicle's diagnostic port with no wiring at all. The 4G OBD GPS Vehicle Tracker suits businesses that want to fit and move devices themselves in seconds.
• Battery-powered trackers work independently of any vehicle power source. They're the answer for trailers, plant, generators and other unpowered assets that thieves love to target.

Real-time 4G tracking also delivers everyday benefits well beyond security, including better route planning, accurate arrival times for customers and clearer insight into how vehicles are being used.

2. Add a Covert Backup Tracker

Professional thieves know where factory trackers and common aftermarket units tend to be fitted. Some will sweep a vehicle and remove what they find before driving far.

A second, hidden tracker gives you a fallback. Battery-powered devices work particularly well here because they don't need wiring, so they can be tucked somewhere unexpected. The Yabby Battery 4G GPS Tracker, for example, lasts up to five years on user-replaceable batteries when reporting once a day, with an optional magnetic base for secure mounting on metal surfaces. Movement-based and more frequent reporting modes are available when you need closer monitoring.

3. Use Geofences and Out-of-Hours Alerts

Most fleet thefts happen when nobody's watching, usually overnight or at weekends. Geofencing lets you draw a virtual boundary around your depot, a customer's site or a driver's home address. If a vehicle leaves that area, you're notified straight away.

Out-of-hours alerts work in a similar way. If a van moves at 2am on a Sunday, you'll know about it immediately rather than on Monday morning. That early warning can make all the difference to a successful recovery.

These tools also help curb unauthorised use of company vehicles, which quietly drives up fuel spend and wear. Geofencing and motion alerts are included in GPSBob's Professional and Enterprise plans.

4. Consider Insurance-Approved Tracking for High-Value Vehicles

For your most valuable vehicles, a Thatcham-approved tracker adds protection that standard GPS can't match. These systems are independently tested, linked to a 24/7 monitoring centre and receive priority police response when a theft is confirmed.

Thatcham S5 systems go further with driver recognition, and versions with immobilisation stop the engine from starting without an authorised tag. Your fleet insurer may even require approved tracking on certain vehicles, and fitting it can help reduce premiums. GPSBob offers S5 and S7 options alongside its standard fleet trackers, so you can match the level of protection to each vehicle's value and risk.

5. Take Key Security Seriously

Keyless theft has changed the game. Relay attacks allow thieves to capture a key fob's signal from inside a building and use it to unlock and start a vehicle in under a minute. Key cloning and programming devices are also widely used.

Strengthen your key management with these steps:

• Store keys in a locked key safe or cabinet, well away from doors and windows
• Give drivers signal-blocking Faraday pouches for keyless fobs
• Keep a signed log of who holds which key and when
• Never leave keys in the ignition, even for a moment during a delivery
• Remind drivers not to leave engines running to defrost on winter mornings, as it's a common opportunity for theft and may invalidate a claim

6. Secure Your Depot and Parking Areas

Where your vehicles spend the night has a huge impact on their risk. A locked, well-lit and monitored yard is far less appealing to thieves than a quiet residential street.

Invest in the basics: secure fencing, lockable gates, bright lighting and CCTV that covers every parking bay. Motion-activated lighting and visible signage add a further deterrent. Where vehicles can't be kept at a depot, park them against walls or close together so rear and side doors can't be opened easily.

7. Upgrade Physical Security on Vans

Factory locks on many vans are a known weak spot. Aftermarket upgrades are relatively inexpensive and make a real difference:

• Deadlocks and slam locks on side and rear doors
• Steering wheel locks and pedal locks as a visible deterrent
• Lock protection plates to stop the "peel and steal" technique
• Van vaults and secure tool storage bolted inside the load area
• Window grilles or security film on rear windows

Visible deterrents often persuade opportunist thieves to move on to an easier target altogether.

8. Protect the Tools and Stock Inside

For many trades, the tools inside a van are worth more than the van itself. Losing them can halt work entirely.

Encourage drivers to remove tools overnight where possible. Mark equipment with your company name, postcode or a forensic marking solution, and register serial numbers on a property database. Tracking high-value kit such as power tools, generators or compressors with a small battery tracker adds another layer of protection.

9. Vet and Train Your Drivers

Not every threat comes from outside. Insider theft and collusion do happen, so thorough recruitment checks and clear policies matter.

Equally important is training. Drivers who understand the risks are far more likely to lock up properly, protect keys and spot suspicious behaviour. Make security part of induction, and refresh it regularly so good habits stick.

10. Mark Vehicles and Use Dashcams

Security marking makes a stolen vehicle harder to sell and easier to identify. Etching the VIN onto windows and marking major components deters thieves who plan to break vehicles for parts.

Dashcams with parking mode can record activity around a vehicle when it's unattended, providing useful evidence for the police and your insurer. Combined with tracking data, they build a clear picture of what happened.

11. Review and Audit Your Security Regularly

Criminal methods change quickly, and a security plan that worked three years ago may already be out of date. Review your arrangements at least once a year, and after any incident.

Use your tracking data as part of that review. Journey histories and alerts can reveal vulnerable parking locations, unusual activity or vehicles that are regularly left somewhere risky.

Keep Your Fleet Safe and Moving

Protecting fleet vehicles against theft isn't about any single measure. It's about stacking the odds in your favour with tracking, physical security, smart key management and well-trained drivers. When those layers work together, thieves are more likely to look elsewhere, and if they do strike, you're far better placed to recover what they take.

GPSBob's fleet trackers give businesses of every size reliable, real-time visibility without long contracts.

Frequently Asked Questions

Does fleet insurance cover tools stolen from vans?

Not usually. Standard fleet insurance covers the vehicle, not its contents. Tools and stock typically need separate tools-in-transit or goods-in-transit cover, so check your policy carefully.

What should I do if a fleet vehicle is stolen?

Report the theft to the police immediately by calling 999 if it's in progress or 101 afterwards. Share live tracking data, then notify your insurer and the DVLA as soon as possible.

Can thieves block GPS trackers?

Some thieves use signal jammers to block GPS and mobile signals. Many modern trackers can detect interference and send alerts, and fitting a second covert tracker reduces the risk further.

Should drivers take company vans home overnight?

It depends on where they live. Vans parked on a secure private driveway may be safer than on a public street. Assess each driver's home parking and consider geofences around those addresses.

How much can a stolen van cost a business?

The true cost goes well beyond the vehicle's value. Lost tools, missed jobs, hire vehicles, admin time and higher future premiums can make a single theft cost several times more than the van itself.
