Black box insurance prices your cover on how you actually drive, rather than only on your age, postcode and car. It’s best known as a way for young drivers to bring down very high premiums, but it now suits some older and low-mileage drivers too. This guide explains how it works, what it records, the catches, and whether it’s likely to save you money.
Is black box insurance worth it? The short answer
- Often worth it for young and new drivers, who pay the highest premiums and have the most to gain from proving they drive carefully.
- Not always cheaper. Consumer Intelligence data reported by Which? in January 2026 found black box quotes were cheaper than standard quotes 42% of the time, with an average saving of £228 when they were. The biggest savings were for younger drivers.
- Compare both. Get standard and black box quotes for the same cover and check the terms before you choose.
How does black box insurance work?
Your insurer tracks your driving with one of three kinds of device:
| Type | How it works |
|---|---|
| Black box | A small GPS unit fitted in the car, usually by an engineer the insurer sends |
| Plug-in device | A matchbox-sized tracker that plugs into a socket under the dashboard |
| App or windscreen tag | A smartphone app, sometimes paired with a tag stuck to the windscreen |
The data builds a driving score, which the insurer can use to reward good driving with discounts, cashback or a cheaper renewal, or to raise the premium if your driving is risky.
What does a black box record?
Each insurer is different, but most look at:
- Speed, compared with the speed limit.
- Braking and acceleration: harsh, sudden movements count against you.
- Cornering and steering.
- When you drive: late-night driving is riskier, especially for young drivers.
- How far you drive.
- Phone use: some app-based policies detect whether you handle your phone while driving.
Many policies let you see your score and journeys in an app, which is useful feedback for a new driver.
Curfews and mileage limits
Strict curfews, where you mustn’t drive between certain hours, are less common than they were, but some policies still score night-time driving more harshly. Read the terms before you buy: driving during a curfew can mean a penalty, a higher excess or a higher premium.
Some policies set a mileage allowance and charge for extra miles, or charge per mile plus a fee for the time the car is parked. Those suit low-mileage drivers but can get expensive if your plans change.
What happens if you drive badly?
- A warning, often by email, text or in the app.
- Lost discounts or rewards.
- A higher premium, sometimes in the middle of the policy.
- In serious or repeated cases, the insurer can cancel the policy. A cancelled policy has to be declared when you next apply for insurance and can make it harder and dearer to get cover.
Black box insurance: pros and cons
| Pros | Cons |
|---|---|
| Can cut premiums for young and new drivers | Not always cheaper than a standard policy |
| Rewards careful driving with discounts or cashback | Bad driving can raise the premium or end the policy |
| App feedback helps new drivers improve | Some policies have curfews or mileage limits |
| Journey data can help settle a disputed claim | Fees for fitting, removing or moving the box to a new car |
| Can suit low-mileage drivers | You’re tracked on every journey |
Your data and privacy
Your insurer holds detailed records of where and how you drive. It’s covered by data protection law, and the insurer must tell you how it uses it. According to Which?, the data can be shared with partners such as claims handlers, and with the police if there’s a court order, you agree, or the insurer suspects fraud. After an accident, journey data can support your account of what happened, but it can also show you were speeding.
Who is black box insurance for?
- Young and newly qualified drivers. Drivers aged 17 to 20 pay the highest premiums, as the ABI explains, so they have the most to save.
- Drivers who’ve had a claim or conviction and want to show they drive safely now.
- Low-mileage drivers, especially on per-mile policies.
- Not ideal for high-mileage drivers, or anyone uncomfortable with being tracked.

Choosing a car with black box insurance
The car still matters. A car in a low insurance group costs less to insure with any policy: see our guide to the cheapest cars to insure, and look up any car’s group with our free car specs check. Before buying a used car, run a full car history check to check it hasn’t been stolen, written off or left with finance owing. See Silver and Gold check prices.
Frequently asked questions
Does black box insurance have a curfew?
Some policies do, but strict curfews are less common than they were. Many score late-night driving instead. Check the terms before you buy.
Can black box insurance go up during the policy?
Yes. If your driving is scored as risky, some insurers can raise the premium mid-term or, in serious cases, cancel the policy.
Is black box insurance cheaper for young drivers?
Often, but not always. Which? reported in 2026 that black box quotes were cheaper 42% of the time, with the biggest savings for younger drivers. Compare standard and black box quotes.
Can I remove the black box?
Not without breaking the policy terms while you’re insured on it. Insurers may charge to remove the box, or to move it to a new car.
