Telematics insurance, often called black-box cover, prices your premium from how you actually drive rather than from broad averages. A small device fitted to the car, or an app on your phone, records speed, braking, cornering, and the times you drive. The insurer uses that data to set or adjust your price. For careful drivers, especially younger ones, it can turn a high premium into a fair one.
How the data is collected
A telematics policy gathers data one of three ways:
- A black box wired to the car, recording trips continuously.
- A smartphone app that uses the phone’s sensors while you drive.
- The car’s own connected systems, where the vehicle is fitted with them.
The device captures how fast you go, how sharply you brake and accelerate, how smoothly you corner, and the time of day you travel. Many policies also reward mileage, because less time on the road means less chance of a crash.
How it changes your price
Traditional motor pricing leans on age, postcode, and claims history, which is why young and new drivers pay more. Telematics adds your real behaviour, so a 19-year-old who drives calmly at sensible hours can score better than the average for their age. Our explainer on why young and new drivers pay more sets out the averages telematics works against.
The insurer scores the driving and reflects it at renewal, and sometimes mid-policy through a bonus for good habits. A poor score, by contrast, can push the price up or end the cover. The Financial Conduct Authority expects the scoring to be clear and the effect on price to be explained.
The benefits and the trade-offs
The upside is a price closer to your true risk and a reason to drive well. Some policies also offer theft tracking and crash alert. The trade-off is constant monitoring: the insurer sees where and when you drive, and that data can be used at claim time to check the stated circumstances.
If privacy concerns you, check what the insurer keeps, how long, and whether it shares the data. The Consumer Duty requires firms to treat customer data responsibly, and our guide to how insurers calculate risk and price cover explains the broader pricing picture.
What to check before you buy
- The scoring factors and how each affects your price.
- Whether a poor score can cancel the policy or just raise the renewal.
- The curfew or time-of-day rules, if any apply.
- What happens to your data if you switch insurer.
Telematics rewards good driving with lower cost, but only if you understand the rules before you commit.
