What the certificate proves, in brief
In short, the certificate is formal proof that an approved tracker was professionally installed on a specific vehicle, listing the device make, model and serial number, the vehicle's registration and VIN, the fitment date, and the centre and installer details. That is the what; the rest of this page is the how.
The insurance significance, why an insurer needs it and what happens at a claim without it, is covered in depth on the proof-of-fitment page. Here the focus is the practical lifecycle: getting the document, submitting it, keeping it, and replacing it when things change.
Getting it at fitment
The fitment centre should hand over the certificate at the time of installation, either as a physical document or emailed shortly afterward, so confirm you have actually received it before you leave the centre. The day of fitment is the easiest moment to get it right.
Check the key details on the spot, particularly that the VIN and registration match your vehicle, because catching a typo while you are still at the centre is trivial, whereas discovering it months later at a claim is not. A two-minute check at handover saves a great deal of trouble.
Forwarding it to your insurer
The tracker discount usually does not apply automatically; you generally have to submit the certificate to your insurer, through the broker, the online portal, or the underwriting email address. Until it is on file, the insurer's position is effectively that no approved tracker is fitted.
Send it promptly after fitment and keep a record that you did, since the gap between fitting the device and the insurer recording it is a window where the discount is not applied and the cover may not reflect the tracker. Confirming receipt with the insurer closes that loop.
Storing and retrieving it
Keep a digital copy in your vehicle-documents folder, because the certificate is needed again at renewal, at a claim, and at any sale of the vehicle, and a saved copy turns each of those into a non-event. Relying on the original paper alone is how certificates get lost.
Do not assume the insurer holds a copy: some do and some rely on you, so retaining your own is the safe default regardless. A clearly named digital file is the difference between answering an underwriting query in seconds and scrambling for paperwork.
Reissuing a lost certificate
If the certificate is lost, the original fitment centre can usually reissue it, and the tracker provider's own records typically support reissuance if the centre's records are unavailable. Expect the process to take from a few days to a couple of weeks, and in some cases a small admin fee.
Because reissuance takes time, the moment to sort it is when you notice the gap, at quote or at an audit, not when a claim is already running and the clock is against you. Saving a digital copy at fitment is the cheapest insurance against ever needing to reissue at all.
Used vehicles and product upgrades
Two situations specifically require a fresh certificate. Buying a used vehicle with an existing tracker: the previous owner's certificate does not carry over cleanly, so confirm the device is active, transfer the subscription into your name, and obtain an updated certificate in your name. Without that, your insurer treats the vehicle as having no approved tracker.
Upgrading or changing the product, even with the same provider, also needs a new certificate, because an old certificate referencing the previous device does not satisfy the cover for the new one. Whenever the device or the vehicle changes, the certificate has to change with it.
The OneCompare view
Treat the certificate as a small but important admin task with a clear lifecycle: get it at fitment and check the VIN, forward it to your insurer and confirm receipt, keep a digital copy, and obtain a fresh one whenever the device or vehicle changes. Reissuance is possible if lost, but it is far easier to handle correctly the first time.
