Telematics or Black Box insurance is a type of car insurance where a device in your car is used to track how you drive. In exchange for sharing your driving data, insurers give you a lower price.
At Marshmallow, our telematics plan is called Marshmallow Move. You don't need a black box, just a simple tag that connects with your phone.
With our quick online set up, we can move at your pace. Your bluetooth tag will be sent in the post, but you can start driving before it arrives.

No. We only record your location when you’re driving and your Tag is connected to the Marshmallow app.
When you’re not on a journey, we don’t track or store your location, and the app doesn’t collect any background data.
Your privacy is really important to us. We only use the information needed to understand your driving and keep your insurance fair, nothing more.
We use your driving data to understand how you drive, keep your insurance fair, and offer you competitive pricing.
Your data helps us calculate your driving score — things like how smoothly you brake, accelerate, and turn, and whether you use your phone while driving — and to offer fair renewals in the future.
We don't share your information with third parties and only record trips when your Tag and app are connected. All data is stored securely and used to enhance your experience and ensure your price reflects your driving habits.
Your Tag will arrive in the post within 2–3 days of buying your policy.
You don’t need to wait for it to start driving — your cover begins right away. Once it arrives, just stick it to your windscreen and connect it to the Marshmallow app. It only takes a minute to set up, and you won’t even notice it’s there.
Yes. You’re fully insured and can start driving as soon as your policy begins.
Your Tag will arrive in the post within 2–3 days, and once it does, it’s quick to set up. Just stick it to your windscreen and connect it to the Marshmallow app.
We ask that you activate your Tag within 7 days so we can start collecting your driving data. If we're unable to collect driving data, your cover may be moved to a different policy plan and the Move discount may no longer apply.
Your driving score is a reflection of how you drive day to day — things like your speed, smoothness, phone use, and how safely you brake or turn. It's updated after every trip.
It's designed to help you understand your driving habits and become more confident behind the wheel. The safer you drive, the better your chances of getting a discount when you renew..
Scores run from 0 to 100. Most customers score well within a normal range — you don't need to drive perfectly, just safely and consistently.
Your driving score doesn't change your price during your current policy. You’ll pay what you agreed to when you bought the policy.
At renewal, your score can help you unlock a better price. Customers who drive well can get better renewal deals.
Everyone makes mistakes, and the occasional error behind the wheel won't have a big impact on your score. But if your score stays consistently low, we may need to review your policy.
