Black Box Track: What Your Telematics Records

A black box track records where, when and how a car is driven using GPS and motion sensors, then sends that data to your insurer to help set or adjust your premium. The device (or a linked app) logs your location, speed, acceleration, braking and cornering, and usually the time of day you drive. Insurers use this to price cover more accurately, which is why telematics can cut premiums for careful drivers, especially newer ones.

Black box insurance, also called telematics, is a policy where a small device or smartphone app monitors your driving and feeds it back to your insurer. It is fully regulated by the Financial Conduct Authority (FCA), so the same fairness and complaints rules apply as with any car insurance. At Free Price Compare we compare cover from a panel of 130+ insurers, including telematics and standard policies, so you can see which suits your driving.

What is black box car insurance and how does it work?

Black box car insurance is a policy where a telematics device, or a smartphone app linked to your account, records how you drive and sends that data to your insurer. The device measures speed, acceleration, braking, cornering and the times of day you drive, and matches it to road speed limits using GPS. Your insurer turns that data into a driving score, and safer scores can lower your renewal price or get access to cashback. Telematics is most useful for higher-risk groups such as new and young drivers, because it lets an insurer price on your actual behaviour rather than assumptions about your age. Around a third of quotes on Free Price Compare come from drivers with no no-claims bonus, and it is exactly this group that telematics is designed to help.

The box itself is either professionally fitted (usually wired near the dashboard) or self-installed by plugging into the OBD port, while app-only policies use your phone’s sensors instead. To understand the wider picture, our explainer on telematics car insurance in the UK breaks down each type.

Does a black box track your location?

Yes, most black boxes track your location, usually accurately to within a few metres, because they rely on GPS to work out your speed against the local limit. The tracking is not there to watch where you go socially; its main job is to log your speed, braking and mileage so your insurer can score your driving. Some policies do use the location data for extra features, such as helping trace a stolen car, and a few older schemes set curfew or mileage limits. In practice, the concern for most drivers is accuracy rather than surveillance: a small number of users report GPS drift, where the box briefly misreports position or speed. If that happens, you can dispute the score with your insurer, and an unresolved complaint can be escalated to the Financial Ombudsman Service.

How much can a black box actually save you?

Drivers aged 17-24 save around £248 a year on average with a black box, paying roughly £1,313 with telematics against £1,561 without, based on independent guidance data for 2026. Savings are largest for the highest-risk groups: for context, the average UK motor premium across all drivers was £560 in Q1 2026, according to the ABI Motor Insurance Premium Tracker, only 0.2% above Q4 2025. Some telematics providers, such as Marmalade, advertise policies up to £300 cheaper than an equivalent standard quote. The saving is not guaranteed, though: a low driving score means little discount, and for lower-risk older drivers a standard policy is often cheaper outright.

If you would rather avoid a device altogether, our guide on getting cheap insurance without a black box covers the alternatives.

Can my black box policy be cancelled?

Yes, a black box policy can be cancelled by your insurer if your driving score falls very low or you repeatedly break the policy terms, but this is not routine and there are always warning stages first. Common triggers include persistent speeding, driving during a barred curfew where one applies, or exceeding an agreed mileage cap. Insurers must treat you fairly under FCA rules and give you notice, so a single mistake will not end your cover. If the box malfunctions, for example through GPS drift wrongly logging speeds, that should not count against you, and you can challenge any score you believe is wrong. Should the insurer refuse to put it right, you can complain and, if still unresolved after eight weeks, take it to the Financial Ombudsman Service free of charge.

Can a black box recover a stolen car?

Some black boxes can help recover a stolen car, because their GPS can pinpoint the vehicle’s location, but not every telematics policy offers this and it is not a substitute for a dedicated tracker. Where the feature exists, your insurer can share the box’s location data with the police to help trace the car after a theft is reported. If stolen-vehicle recovery matters to you, check the policy documents rather than assuming it is included, as many telematics products focus purely on scoring your driving. A separate consideration after a theft or write-off is any shortfall between the payout and what you paid, which is where GAP insurance can help.

Is a black box good for young and new drivers?

A black box is often the cheapest route to legal cover for young and new drivers, because it lets insurers reward safe driving instead of charging a flat high-risk premium. New drivers face some of the highest quotes in the market, and telematics can bring these down by hundreds of pounds for those who drive carefully. On Free Price Compare, drivers aged 17-25 make up around a fifth to a quarter of quotes but convert to a sale far less often, which reflects how price-sensitive this group is when shopping around. A black box is not the only lever, though: choosing a low-insurance-group first car, adding an experienced named driver and completing extra training all help. Our young driver insurance strategies and new driver car insurance guide set out the full range of options.

One car, two young drivers: how does the black box score work?

With one car and two young drivers on a black box policy, the device scores the vehicle rather than each person individually, unless the policy uses a linked app that can separate drivers. Most fitted boxes cannot tell who is behind the wheel, so both drivers’ behaviour affects the same combined score and the same renewal price. App-based telematics can sometimes assign a trip to a specific named driver, giving each their own score, but this varies by provider and should be confirmed before you buy. If two young drivers need to share a car, check whether the policy scores by device or by app, because it directly affects how one driver’s mistakes hit the other. For provisional and learner situations, our learners car insurance guide explains how short-term telematics cover can work.

How is a self-installed black box fitted, and can I remove it?

A self-installed black box is fitted by plugging it into your car’s OBD port, usually found under the dashboard near the steering column, and it starts recording as soon as it has power and a GPS signal. Professionally fitted boxes are wired into the car instead and should only be removed by an approved installer. Removing or unplugging a box without permission breaches your policy terms and will normally invalidate your cover, so it should never be done to avoid monitoring. If you receive a self-install device, your insurer can see when it is connected and active, and gaps in data can flag a problem. Insurers use your driving data mainly to score you fairly, not to catch you out, but consistently high speeds or heavy braking will lower your score and can affect renewal.

Am I allowed to drive at night with a black box?

Most modern black box policies let you drive at any time of day, including at night, but a minority still apply curfews or charge higher scores for late-night driving because that is when accident risk is statistically highest. If a policy has a curfew, driving outside the agreed hours can reduce your score or, in strict cases, count as a breach. Always read the policy documents to check whether night driving is restricted, penalised or simply monitored. For most drivers the box records night trips without banning them, but heavy late-night mileage may nudge your score down. If your work or study means regular night driving, choose a telematics policy that scores fairly across all hours rather than one with a hard curfew.
