Insurance tracker requirements: which cars, which insurers, and what they check
No UK insurer publishes a list of cars it will only cover with a tracker. Each one sets the condition on your own quote, usually from the car's value, its theft record and where it is kept. In the six published ombudsman cases below, tracker conditions started at car values of £35,000, £50,000 and £75,000, and in all of them the insurer said the tracker was missing, not working or out of subscription when the car was taken.
- Published lists of tracker-only cars
- None found
- Value triggers in ombudsman cases
- £35,000 to £75,000
- Claims the ombudsman did not uphold
- 4 of 6
- Cars stolen in 2025 (DVLA)
- 54,830
What makes an insurer add a tracker condition
Insurers do not explain their pricing in public, so treat these as the factors that show up in the published evidence rather than a formula.
- The car's market value. Every value-based condition below is worded around market value at the time of the theft, not the price you paid. The lowest trigger we found was £35,000 and the highest £75,000.
- The model's theft record. Thatcham Research describes its work as “conducting security assessments for insurers on all new and facelifted models launched into the UK” (Thatcham Research). Models that thieves target get a closer look at quote time.
- Where the car sleeps. A garage, a gated drive and a busy street are priced differently, and in some city postcodes an insurer may ask for secure parking as well as, or instead of, a tracker.
- The policy type. Four of the six cases are business, hire or fleet policies, where the condition is written into the schedule for every vehicle over the limit.
Tracker conditions insurers have actually used
These are the exact conditions from six decisions the Financial Ombudsman Service has published, issued between 2015 and 2025. Each one is the wording of a single policy at that time. Insurers change their terms, so read these as real examples of what a condition looks like, not as the rule for every customer of that insurer today.
Enterprise Insurance Company plc · Self-drive hire business
Ombudsman: Not upheld · decided 2015 · decision DRN9788782
When it applied: Market value over £35,000. What it asked for: An operational Thatcham approved category 5 tracking device.
“all vehicles with a market value in excess of £35,000 must be fitted with an operational Thatcham approved category 5 vehicle tracking device”
What went wrong: The tracker had been switched off about two years earlier and had no subscription. The car was stolen two days after it was added to the policy.
The lesson: A grace period for other kit on the schedule did not stretch to the tracker, so the condition applied from the day the car went on cover.
MS Amlin Insurance SE · Business fleet
Ombudsman: Upheld · decided 2023 · decision DRN-4003098
When it applied: Market value of £50,000 or more. What it asked for: An operational and active Thatcham approved Category 5 or 6 tracking device.
“any insured vehicle with a market value of 50,000 GBP or more is fitted with an operational and active Thatcham approved Category 5 or 6 tracking device”
What went wrong: There was no evidence the tracker was active when the car was stolen. The ombudsman averaged three trade valuation guides and put the car at £46,741.
The lesson: Below the threshold the condition did not apply at all, so the market value at the time of the theft decided the claim.
Chubb European Group SE · Private motor
Ombudsman: Partly upheld · decided 2023 · decision DRN-3948169
When it applied: Named on the policy for the insured cars. What it asked for: A tracking system with pro-active automatic driver recognition, with the subscription kept up throughout the policy.
“an anti-theft vehicle tracking system with Pro-Active Automatic Driver Recognition is securely fitted”
What went wrong: Two cars were taken after a burglary in which the keys were stolen. One did not have the required driver-recognition system; the other had one that had never been activated.
The lesson: The ombudsman found the missing system was material to the loss, so the insurer could fairly decline that car's claim.
Aviva Insurance Limited · Business fleet
Ombudsman: Not upheld · decided 2024 · decision DRN-4574879
When it applied: Market value over £75,000. What it asked for: A Thatcham Quality Assured Category S5 (or 5) tracking system, fully working, with the subscription maintained.
“unless at the time of the theft a Thatcham Quality Assured Category S5 or 5 Vehicle Tracking System is fitted, fully operational”
What went wrong: The tracker subscription had run out before the policy began. The car maker's connected-car app was not an S5 system.
The lesson: A phone app from the car maker did not count as the S5 system the policy named, and an expired subscription broke the condition.
NFU Mutual · Private car (added at renewal)
Ombudsman: Not upheld · decided 2024 · decision DRN-4815121
When it applied: Cars over £75,000, under the insurer's underwriting criteria described in the decision. What it asked for: An operating Thatcham approved tracking device, with the subscription maintained.
“unless at the time of the loss YOUR CAR is fitted with an operating Thatcham Approved Tracking Device”
What went wrong: The tracker lost its signal after a garage repair and the subscription failed. The insurer was not told, and the car was stolen months later.
The lesson: A tracker that stops reporting after a repair has to be fixed, and the insurer told, straight away.
AXA Insurance UK Plc · Small business fleet
Ombudsman: Not upheld · decided 2025 · decision DRN-4913258
When it applied: Endorsed on that vehicle when it joined the policy. What it asked for: A tracking device declared to and approved by the insurer, fully operational.
What went wrong: The tracker turned out to be inactive, which the policyholder only found out after the theft.
The lesson: A condition that has sat on a vehicle for years still applies on the day it is stolen, so check the tracker is live at every renewal.
The pattern across all six: none of the disputes was about brand. They were about the type of system (a phone app or a basic unit where the policy named a category or driver recognition), or about a tracker that was missing, switched off or out of subscription on the day, often without the insurer being told it had stopped working.
Cars where the question comes up
Being on this list does not mean every insurer will ask you for a tracker. It means the model's theft record is part of the picture when you are quoted. These are the 20 most stolen models in the latest full-year DVLA figures, covering 2025 and released in February 2026.
| Rank | Model and its theft risk page | Stolen |
|---|---|---|
| 1 | Ford Fiesta | 3,511 |
| 2 | Volkswagen Golf | 1,625 |
| 3 | Ford Focus | 1,474 |
| 4 | Toyota RAV4 | 1,319 |
| 5 | BMW 3 Series | 1,249 |
| 6 | Nissan Juke | 1,200 |
| 7 | Toyota C-HR | 967 |
| 8 | Lexus NX | 951 |
| 9 | Range Rover Evoque | 895 |
| 10 | Vauxhall Corsa | 874 |
| 11 | Land Rover Discovery Sport | 813 |
| 12 | Ford Kuga | 799 |
| 13 | Vauxhall Astra | 758 |
| 14 | Mercedes-Benz C-Class | 826 |
| 15 | BMW 1 Series | 754 |
| 16 | Range Rover Sport | 700 |
| 17 | Nissan Qashqai | 695 |
| 18 | Audi A3 | 658 |
| 19 | Kia Sportage | 653 |
| 20 | Toyota Prius | 644 |
Higher-value prestige cars can attract a tracker condition even when they are not on the DVLA list, because the cost of one claim is so large. Range Rovers, two of which are also on the list, are the best documented case of insurers going further than a tracker:
- Autocar reported that in 2022 Range Rovers were the second most stolen cars in the UK, with over 5,200 taken, and that many insurers stopped covering London-based Range Rovers or sharply raised premiums. (Autocar)
- Fleet News reported that some insurers declined to cover Range Rovers, and that Jaguar Land Rover relaunched its own insurance offer in response. (Fleet News)
- As far back as 2014, Insurance Times reported insurers asking for secure or underground parking before covering new Range Rovers in London, with one broker saying even a tracker would not change most insurers' answer. (Insurance Times)
Five ways a tracker condition is worded
- A category. “S5” or “S7” (or the older “Category 5” and “Category 6”). Any product certified in that category should satisfy it, but ask the insurer to confirm the older names map to the current ones.
- Driver recognition. Wording like “automatic driver recognition” points to an S5-type system that tells the owner from a thief, normally with a tag or card the driver carries.
- Approved by us. Some policies need the device to be declared to and accepted by the insurer, not just certified.
- Fitted, operational and subscribed. Nearly every wording above says the tracker must be working and the subscription kept up. A lapsed payment breaks the condition.
- A value line. “Market value over £…” means the condition switches on and off with the car's value, which falls as it ages.
Check your condition and write to your insurer
Fill in what your schedule says. Nothing is sent anywhere: this runs in your browser and builds a checklist and an email you can copy.
Proof to keep, and when to send it
- The installation certificate. It should show the product, its category, the date fitted and your VIN.
- The subscription confirmation. Keep the renewal receipts, not just the first one, and set a reminder before each one is due.
- Proof it is live. A screenshot from the tracker app or the monitoring centre's confirmation, taken at each policy renewal.
- Your insurer's reply. If they confirmed in writing that a product or category is acceptable, keep that email with the policy.
- A note of any fault. If the tracker stops reporting after a battery change or a garage visit, tell the insurer and the tracker company the same day.
If an insurer says no, or the price jumps
- Ask what security would change the answer. Some will quote with a named category of tracker, an immobiliser or secure parking.
- Try a specialist broker for high-value or modified cars; they deal with tracker endorsements every day.
- Fit both halves of dual layer protection: an immobiliser that stops the car leaving and a tracker that helps get it back. Tell the insurer about both.
- Check the condition again whenever the car's value falls. A condition tied to a value line may drop away as the car ages.
Questions about insurance and trackers
Is there an official list of cars that need a tracker for insurance?
No. We could not find one from any insurer, from Thatcham Research or from the ABI. Each insurer decides on your quote, so the only reliable answer is the wording on your own schedule.
Does the car maker's own app count as an insurance tracker?
Not unless your insurer says so. In one published ombudsman case the car maker's connected-car app was not accepted as the S5 tracking system the policy named.
What happens to a theft claim if my tracker subscription has lapsed?
If the policy says the subscription must be maintained, the insurer can refuse a theft claim. That happened in several of the ombudsman cases on this page, and the ombudsman sided with the insurer.
Can an insurer add a tracker condition at renewal?
Yes. Insurers can change their terms when a policy renews, and one case above began with a condition added at renewal. Read the renewal schedule, not just the price.
Should I tell my insurer if I fit a tracker nobody asked for?
Yes. Security is one of the details your quote is based on, so updating it keeps your policy accurate and may affect your price. Ask before you buy if you want a specific category recognised.
Have the condition in front of you?
