Black Box Insurance Explained: How Telematics Works in the UK

Summary

• Black box tracks your driving: Speed, braking, cornering, and when you drive are all monitored.
• Can save 20-40% on premiums: Safe drivers pay less. Especially beneficial for young and new drivers.
• Some drawbacks: Late-night driving can increase costs. And there are penalties for tampering.

Car insurance for young drivers is painfully expensive. A black box (telematics) policy can bring those costs right down.

But how does it work? What does it track? And is it really worth having a device monitoring your every move? Let's find out.

What Is Black Box Insurance?

Black box insurance uses a small device fitted to your car (or a smartphone app) to track how you drive. Your insurer uses this data to set your premium.

If you drive safely, you pay less. If you drive recklessly, you pay more — or your policy could be cancelled.

It's also called telematics insurance. The "black box" is a GPS device about the size of a smartphone that's usually hidden under the dashboard.

What Does the Black Box Track?

• Speed: Are you sticking to the speed limit?
• Braking: Do you brake smoothly or slam on the brakes?
• Acceleration: Do you pull away gently or floor it?
• Cornering: Do you take corners at safe speeds?
• Time of day: Late-night driving (11pm-5am) is riskier and can increase your score penalty.
• Mileage: How many miles you drive in total.

Your driving data is turned into a score. A high score means lower premiums at renewal.

How Much Can You Save?

Savings depend on your age and driving behaviour:

Driver Type	Typical Saving
Young driver (17-19)	20 - 40%
New driver (20-25)	15 - 30%
Experienced driver (25+)	5 - 15%

For a 17-year-old, this could mean saving £500-£1,000 per year. That's a significant amount.

App-Based vs Fitted Box

Some insurers now use smartphone apps instead of a fitted box. This tracks the same data using your phone's GPS and sensors.

App-based telematics is easier to set up and transfer between cars. But it requires you to carry your phone on every journey and can drain your battery.

Fitted boxes are more accurate and don't rely on your phone. But installation takes time and the box stays with the car.

Tips for a Good Driving Score

1. Obey speed limits: This is the biggest factor. Even 1 mph over can affect your score.
2. Brake gently: Anticipate stops and slow down gradually.
3. Avoid late-night driving: 11pm-5am driving is penalised on most policies.
4. Drive smoothly: Gentle acceleration and smooth cornering score well.
5. Keep mileage reasonable: Higher mileage means more exposure to risk.

Is Black Box Insurance Worth It?

For young and new drivers, almost always yes. The savings are substantial if you drive well.

For experienced drivers with a good no claims bonus, the savings are smaller. A standard policy may be just as cheap.

Compare black box quotes alongside standard policies. The cheapest option varies by person. Read our insurance types guide for more.
