Approval, Types and Costs
A car insurance tracker is a monitored device fitted to your vehicle that helps locate it if it is stolen. Many insurers now ask whether one is fitted, and for some cars, it is a condition of the policy.
If your car is high-value or a common target for theft, your insurer may require a Thatcham-accredited tracker, and fitting one can lower your insurance premium. These devices are often labelled S5 or S7, and some are also known as VTS (Vehicle Tracking Systems).
The right choice depends on your car, your budget, and what your insurance policy requires. Understanding how the technology works, who monitors it and how it is installed will help you improve your vehicle security without paying for features you do not need.
Key Takeaways
- Monitored trackers help police recover stolen vehicles and may be required by your insurer.
- Accredited devices such as S5 and S7 suit different cars, values and policy conditions.
- Professional installation and an active subscription keep your cover valid.
How Insurance-Approved Vehicle Tracking Works
An insurance-approved tracker is a device tested by Thatcham Research and accepted by UK insurers as a genuine security measure. It uses a mix of satellite, mobile and radio signals to pinpoint your vehicle, and it links to a monitoring centre that works with the police when a theft happens.

What Insurers Mean by Approved
“Insurance approved” is not a marketing phrase you can use for any GPS box on an online marketplace.
It means the device has passed independent testing by Thatcham Research, the UK’s motor insurance research centre. Products that pass carry Thatcham Quality Assured accreditation and sit in a set category, usually S7 or S5.
Your insurer will normally name the category it needs, then ask for two things:
- Proof of installation — a certificate from an approved fitter
- An active subscription — the monitoring service must be paid up and running
If the subscription lapses, the Tracker is no longer doing the job your policy relies on. That can affect a claim, so keep the renewal date in your diary.
GPS, GSM and VHF Tracking Technology
Most trackers combine three technologies, and each one covers a weakness in the others.
| Technology | What it does | Weak point |
|---|---|---|
| GPS (Global Positioning System) | Uses satellites to fix your vehicle’s position, often within a few metres | Signal is lost underground or inside metal containers |
| GSM | Sends that position over the mobile phone network to the monitoring centre and your app | Can be blocked by signal jammers |
| VHF | A short-range radio signal the police can home in on | Only works once a recovery team is fairly close |
Thieves sometimes use cheap jammers to knock out GPS and GSM. VHF is the reason some devices, including those from Tracker, can still be located in a shipping container or a basement car park.
Thatcham S7 and S5 Categories
The category you need usually depends on your vehicle’s value and theft risk.
Category S7 is the entry level. It gives you location tracking and 24/7 monitoring, plus alerts if the device is disconnected or the battery is tampered with. It suits most cars, vans and motorcycles.
Category S5 adds driver recognition. You carry a small tag or fob, and if the vehicle moves without it, the monitoring centre treats that as a possible theft straight away. This matters because many modern thefts involve key cloning or relay attacks, in which the vehicle is driven off without forced entry.
Insurers commonly ask for S5 on higher-value vehicles, prestige models and motorhomes.
Stolen Vehicle Recovery and Police Support
Report the theft and the monitoring centre gets to work. Staffed 24 hours a day, every day of the year, it confirms the theft with you, then begins tracking the vehicle.
The centre passes live location data to the police, giving officers a direction of travel rather than a cold trail. Some providers, including Tracker, have a formal working agreement with UK police forces, which speeds up that handover.
Two things you should do to help recovery:
- Report quickly — the first hour matters most, as vehicles are often broken up or moved to a port fast
- Keep your details current — the centre needs to reach you to confirm the theft before it escalates
Recovery is never guaranteed. Even so, a monitored tracker gives the police information they would not otherwise have.
Choosing, Fitting and Using the Right Device
The right car insurance tracker depends on your vehicle’s value, your insurer’s terms, and how you plan to use the tracking data day-to-day. Costs, professional fitting and the certificate you send to your underwriter all matter just as much as the hardware itself.
Matching Tracker Features to Your Vehicle
Start with the Thatcham category your insurer asks for. S7 devices offer GPS location and basic movement alerts, while S5 adds driver recognition tags, so the monitoring centre knows if the car moves without your key card present.
Higher-value cars, especially keyless models targeted by relay theft, usually need S5.
Then match the device to the vehicle type. Car trackers and van trackers can use hard-wired power, while motorcycle trackers and scooter trackers need compact units with tamper alerts and battery backup.
Motorhome and caravan trackers benefit from geofencing and tow-away alerts, since these vehicles often sit idle for weeks.
Also check signal technology. A GPS car tracker paired with VHF is harder to defeat with a signal jammer than GPS alone.

Installation, Activation and Insurer Evidence
Most insurers only accept a car tracking device fitted by an approved engineer. Self-fitted units, and consumer trackers like AirTags, rarely satisfy policy conditions.
Fitting usually takes one to two hours. Many suppliers offer mobile installation at your home or workplace.
After fitting, you must:
- Register the device with the monitoring centre.
- Activate your subscription so the secure operating centre can respond 24/7.
- Request the installation certificate.
- Send that certificate to your insurer or broker.
Keep a copy. If your policy lists a tracker as a condition and you cannot prove it was fitted and live, a theft claim can be refused.
Costs, Subscriptions and Potential Premium Effects
Budget for three separate costs, not one.
| Item | Typical range |
|---|---|
| Device and professional fitting | £250–£600 |
| Annual monitoring subscription | £100–£250 |
| S5 driver tags or extra features | £30–£100 |
Savings on your insurance premium vary. Some insurers offer a modest discount, others treat the Tracker as a requirement for cover rather than a discount trigger.
Ask for a quote with and without the Tracker before you buy. If cover is refused without one, the real value is access to the policy, not the saving.
Subscriptions renew annually alongside costs like your car insurance and VED, so factor them into your yearly motoring budget.
Live Tracking, Alerts and Everyday Management
Most vehicle trackers come with a mobile app that shows live tracking, journey history, and battery status. You can usually set a geofence and get a notification if the vehicle leaves that area.
Useful alerts include ignition on, unusual movement, low battery and tow-away detection.
Test the app soon after installation. Check that the location refreshes, notifications reach your phone and your contact details are correct at the monitoring centre.
Update those details if you change your number or move house. The centre will call you before alerting the police, so an old number delays recovery.
Separating Security Trackers From Insurance Reminder Apps
Not every product with “tracker” in the name protects your vehicle from theft.
- Insurance-approved trackers are hardware fitted to the car, monitored by a control room, and accepted as evidence by your underwriter.
- Insurance reminder apps and document wallets, including tools on sites such as safeandsoundmobile.co.uk, store renewal dates and policy paperwork. They track deadlines, not location.
- Telematics black boxes score your driving to set your premium. Some include location data, but they are not always Thatcham-certified for theft recovery.
If you share licence or policy details online, check the site’s connection security first and look for HTTPS before entering personal information.
Frequently Asked Questions
Car trackers fall into two groups: stolen vehicle recovery devices approved to Thatcham S5 or S7, and telematics boxes that monitor how you drive. The answers below explain how each type works, what it costs, and how it affects your premium.
How do car insurance tracking devices work?
A telematics device records data about your driving. It measures your speed, how hard you brake, how sharply you corner, and often the time of day you travel.
That data is sent to your insurer via a mobile signal. Your insurer then scores your driving and adjusts your premium accordingly.
Stolen vehicle recovery trackers work differently. They stay hidden in your car and send its location to a monitoring centre when theft is reported. Some use VHF radio signals and GPS, which help when a car is hidden underground or inside a metal container.
Telematics comes in three formats:
- Black box – a unit fitted permanently by an engineer
- Plug-in device – slots into the OBD port under your dashboard
- App only – uses your phone’s sensors, with no hardware needed
Is car insurance cheaper with a tracking device?
It can be, but nothing is guaranteed. Telematics policies often suit younger drivers or people with little claims history, since safe driving data can reduce premiums over time.
With Thatcham-approved security trackers, many UK drivers report savings of roughly 5% to 30%. The exact figure depends on your insurer, your car, and your postcode.
Keep in mind the running costs. Recovery trackers usually need a subscription, and installation by an approved fitter costs extra.
Should I allow my insurer to track my driving?
That depends on your habits. If you drive mostly in daylight, stay within speed limits, and cover low mileage, a telematics policy is likely to work in your favour.
If you do a lot of late-night driving or long motorway trips, the score may not help you. Some policies also charge extra or restrict cover if you drive during certain hours.
Read the policy terms before you sign. Look at how the score is worked out, how often it updates, and what happens if your rating drops.
What are the risks of using a car insurance tracker?
The main risk with telematics is a poor score pushing your renewal price up. A few policies can cancel cover if driving repeatedly breaches the agreed limits.
Privacy is another consideration. Your insurer holds records of where and when you drive, so check its data policy and how long it keeps the information.
For security trackers, the risks are practical. A device that is not fitted properly may drain the battery or fail to report, and letting the subscription lapse means the monitoring service stops.
Can an insurance company fit a tracker to my vehicle?
An insurer cannot fit anything without your agreement. However, it can make a tracker a condition of cover, and this is common for high-value cars, performance models, and vehicles kept in areas with high theft rates.
If that condition applies, you arrange installation with an approved fitter and send proof to your insurer. Fitting the wrong device category, or using an unapproved installer, can invalidate your policy.
For telematics policies, you choose to take the product. The insurer then supplies the box, plug-in unit, or app as part of the deal.
Which car insurance tracking device is best?
There is no single answer, but Thatcham accreditation is the standard to look for. Category S5 devices include driver recognition, usually via a tag or card, and alert the monitoring centre if the car moves without the driver present. Category S7 devices track and alert but have no driver ID feature.
Insurers normally specify S5 for higher-value or higher-risk vehicles, and accept S7 for others. Check your policy wording first, because fitting an S7 when S5 is required will not satisfy the condition.
Beyond the category, compare monitoring hours, European cover, subscription price, and whether the system uses VHF alongside GPS to resist signal jammers.
Safe and Sound Essex
If you’re looking for an insurance-approved tracker in Essex, Safe and Sound is a fitter you can consider.
The company is based in Rettendon, Essex, and works across the county and nearby areas. It has its own workshop with a waiting area, so you can stay while the work is done.
Mobile fitting is also available. An engineer can come to your home or workplace instead, saving you a trip to the garage.
Here’s what they offer beyond trackers:
| Service | Details |
|---|---|
| Vehicle tracking | Insurance-approved and fleet options |
| Immobilisers | Ghost immobilisers for keyless theft protection |
| Car security | Alarms and van deadlocks |
| Extras | Parking sensors, window tinting, car audio |
The installation team is Fitas approved. That matters because most insurers will only accept a tracker fitted by an accredited engineer.
Their tracker range includes brands such as SmarTrack, Clifford,, d Viper security products.
Why does the fitter matter for your insurance? Your insurer usually asks for a fitting certificate before applying any discount. A properly documented install protects your claim if the vehicle is ever stolen.
You can check reviews on Trustpilot, where the company has feedback from over 200 customers. That gives you a reasonable idea of what to expect before you book.
If you’re outside Essex, look for a local installer with the same Thatcham and Fitas credentials.
