Is black box insurance actually worth it? For most young drivers, a telematics policy is one of the cheapest ways to get insured – with average savings of over £1,000 a year. We break down how it works, the pros and cons, and how to find the best deal.
If you're a young or new driver, you've probably seen black box insurance (also called telematics insurance) come up when searching for cheap car insurance. The idea is simple: a small device or phone app tracks how you drive, and if you drive safely, you could pay less. But is it actually worth it? Here's what you need to know.
When you take out a telematics car insurance policy, your insurer monitors how you drive using one of three methods: a small device fitted to your car, a plug-in gadget you install yourself, or an app on your phone. The device or app tracks things like your speed, braking, how smoothly you corner, the time of day you drive, and how many miles you cover.
This data builds up a picture of how safe you are behind the wheel. You can usually check your driving score on an app. When it's time to renew, your insurer uses this data to set your new price. Drive well and your premium could drop by 20–40%. Drive badly and it could go up – or in serious cases, your policy could be cancelled.
Fitted black box: Installed behind your dashboard by a professional. The most accurate, but you'll need to book an appointment.
Self-fit plug-in: A small gadget you plug into your car's 12V socket or OBD port. Easy to set up yourself.
Smartphone app: No device needed – just download the app and it uses your phone's GPS and sensors. The most convenient option, and getting more popular.
For most young drivers, yes. If you're aged 17–25 and facing a big insurance bill, cheap telematics insurance is one of the best ways to bring the cost down. The numbers speak for themselves – drivers aged 17–20 save an average of £1,137 a year by going with a black box policy instead of a standard one.
But it's not for everyone. If you regularly drive late at night, cover a lot of miles, or just don't like the idea of being tracked, a standard policy might suit you better. The key is to compare both options and see which is actually cheaper for you.
Big savings. Cheap black box insurance can cut your premium by hundreds – sometimes over £1,000 a year for young drivers.
Fairer pricing. You're judged on how you actually drive, not just your age or postcode.
Makes you a better driver. Telematics users have 20–30% fewer accidents in their first year. The feedback genuinely helps.
Theft tracking. If your car is stolen, GPS data can help find it.
Builds your record. Good scores help you get cheaper quotes in future, even when you switch to a standard policy.
Late-night driving can hurt your score. Most insurers mark down journeys between 11pm and 5am. Not great if you work shifts.
Mileage limits. Some policies cap your annual miles (usually 7,000–10,000). Go over and you'll pay extra – typically 10–20p per mile.
Privacy. Your insurer can see when and where you drive. Data is protected under GDPR, but it's still a trade-off.
Poor driving costs more. If your scores are bad, your renewal could be more expensive than a standard policy.
Switching hassle. Fitted devices need to be removed if you change insurer. App-based options avoid this.
Telematics insurance works best for drivers who are confident they drive safely and want a fairer price. You'll get the most out of it if you tick a few of these boxes:
You're 17–25. This is where the savings are biggest. If you're a young driver paying over £1,500 a year, a black box policy could make a real dent in your costs.
You're a new driver. Just passed your test? Without any driving record, insurers assume you're high risk. A telematics device lets you prove otherwise. Our first car insurance guide has more tips for getting started.
You don't drive much. Lower mileage usually means a better score. If you're not sure how many miles you do, our mileage calculator can help you work it out.
You mostly drive during the day. Night-time driving is scored more harshly, so daytime drivers tend to see the best results.
If you're over 25 with several years of no claims bonus, a standard policy is often just as cheap – or cheaper. Experienced drivers with clean records already get good rates without needing to be monitored. Always compare both options before you decide.
1. Compare quotes with and without a black box. Don't assume telematics will always be cheaper. Get quotes for both and compare. You can compare quotes from 130+ insurers via Brumble in minutes.
2. Pick a car in a low insurance group. A smaller, less powerful car will always be cheaper to insure – with or without a black box. See our cheapest cars to insure guide for the best options.
3. Get quotes 3 weeks before renewal. Research shows this is the sweet spot for the best prices. Last-minute buyers pay more. Our guide to lowering your premium explains why.
4. Check the mileage cap. Make sure the allowance fits your driving. Going over costs 10–20p per mile, which adds up fast.
5. Don't auto-renew. Even with a good driving score, your insurer's renewal offer might not be the cheapest. Always shop around.
After a year of safe driving, your insurer will use your telematics data to offer a renewal price. This is where the real savings kick in. Some drivers see their premium drop by 30–50% at their first renewal.
But don't just accept it. Even with a good score, it's always worth comparing your renewal quote against other insurers. Your telematics data builds your overall driving record, which helps you get better quotes everywhere – not just with your current provider. And once you've built up a couple of years of no claims bonus, you might find a standard policy is cheaper anyway.
Most young drivers benefit from 1–3 years of black box cover. After that, with a clean record and a growing no claims discount, cheap car insurance becomes much easier to find without a telematics device.
