Black box car insurance – also called telematics insurance – uses technology to monitor your driving behavior and adjust your premium based on how safely you drive. For many drivers, particularly young or newly qualified motorists, black box policies offer substantial savings compared to traditional insurance. This guide explains how black box insurance works, who benefits most, and whether it's the right choice for you.
Black box insurance is a type of car insurance where your premium is based partly on how you actually drive, rather than just statistical risk factors like age and location. A small device (the "black box") or smartphone app monitors your driving behavior and shares this data with your insurer.
The term "telematics insurance" is the technical name for the same product – "black box" and "telematics" are used interchangeably in the UK market. According to the British Insurance Brokers' Association, over 1.2 million UK drivers now use telematics insurance, with the market growing by approximately 15-20% annually.[1]
There are two main ways insurers monitor your driving:
Black box systems typically track the following parameters, as outlined in FCA-regulated insurance policy documentation:[4]
Different insurers use different models, but typically:[8]
Typical scoring criteria (varies by insurer):[10]
This is the primary market for black box insurance. According to the Association of British Insurers, young drivers face average premiums of £2,000-3,000+,[12] but research by Consumer Intelligence shows that safe drivers with black boxes typically save 20-40%, bringing costs down to £1,200-2,000.[13]
Why it works well:
Anyone who's just passed their test – regardless of age – benefits from demonstrating safe driving early to build a good track record.
After a driving ban, premiums can increase by 200-500%.[15] Black box policies allow you to prove you're now a safe driver and rebuild your insurance history.
If you drive fewer than 5,000 miles annually, black box policies reward this lower exposure to risk with potential savings of 10-25%.[16]
The biggest benefit is cost reduction. Research by MoneySuperMarket shows young drivers regularly save £500-£1,200 per year compared to standard policies.[20] Some insurers also offer monthly savings for consistently good driving – Admiral LittleBox, for example, offers £150-300 cashback for safe driving during the policy year.[21]
Most black box policies provide access to an app or online portal showing your driving scores. Research published in the journal Accident Analysis & Prevention found that telematics users show measurable improvements in driving behavior within 3-6 months:[22]
The GPS tracking in black boxes helps police locate stolen vehicles. According to Tracker Network UK, vehicles with GPS tracking devices have recovery rates exceeding 85%, compared to the national average of 42%.[23]
Black box data can prove you weren't at fault in disputed accidents. The device records your exact speed, location, and driving behavior at the time of an incident, providing evidence that can prevent unjust liability findings.[24]
Parents of young drivers can monitor their children's driving behavior (with the child's consent under data protection regulations),[25] ensuring they're developing safe habits.
Many policies penalize driving between 11pm-5am. Department for Transport data shows this is when 40% of serious young driver accidents occur,[7] so insurers score these journeys more harshly. Some budget policies have outright curfews where you cannot drive during these hours without penalty. This is problematic if you:
Most black box policies limit annual mileage to 7,000-10,000 miles.[19] Exceeding your limit may result in:
Your insurer knows:
While insurers claim they only use data for pricing (and must comply with UK GDPR regulations),[26] some drivers are uncomfortable with this level of monitoring. The Information Commissioner's Office has published guidance confirming insurers must be transparent about data usage.[27]
If your driving is consistently poor, some insurers reserve the right to increase your premium mid-term or refuse to renew. Research by Which? found that approximately 8% of telematics policyholders saw premium increases due to poor driving scores.[28]
For physical black boxes, you'll need to arrange installation (typically 30-60 minutes at a garage). While usually free, this requires taking time out of your day.
App-based systems require:
Savings depend on your driving profile and how safely you drive. Here's data from Consumer Intelligence's 2024 analysis:[13]
| Driver Profile | Standard Premium | Black Box Premium (Safe Driving) | Annual Saving |
|---|---|---|---|
| 17-year-old, first car | £2,500 | £1,500-£1,800 | £700-£1,000 |
| 19-year-old, 2 years experience | £1,800 | £1,200-£1,400 | £400-£600 |
| 25-year-old, newly qualified | £1,400 | £1,000-£1,200 | £200-£400 |
| 30-year-old, returning after ban | £2,000 | £1,400-£1,600 | £400-£600 |
Savings assume consistently good driving scores (85+). Poor driving may result in minimal savings or even higher costs.
Research by Insure The Box shows that staying within speed limits is the single most important factor in driving scores, accounting for approximately 40% of your total score:[29]
These insurers specialize in or offer competitive black box policies:[30]
Policies vary significantly between insurers in terms of what's monitored, how scores are calculated, curfews, mileage limits, and premium adjustment timing. Always compare the specific features of each policy.
Yes, the GPS tracking means your insurer can see your location data. However, UK insurers must comply with GDPR regulations[26] and FCA rules regarding data usage.[4] Insurers state they use this data only for pricing risk and recovering stolen vehicles, not for tracking your daily movements or sharing data with third parties without consent.
Most insurers charge per additional mile (typically 10-20p per mile).[19] Some offer the option to purchase additional mileage upfront at a lower rate. Significantly exceeding limits without paying may result in policy cancellation.
Most policies allow it but score these journeys more strictly (often 30-50% more harshly).[18] Budget policies may have complete curfews. Check your specific policy terms – emergency journeys are usually permitted even with curfews.
Some insurers reserve this right, though most simply offer smaller discounts at renewal rather than mid-term increases. Research by Which? found approximately 8% of telematics users experienced premium increases due to poor driving.[28] The key risk is renewal refusal if driving is consistently dangerous.
Most young drivers benefit from 1-3 years of black box insurance. Once you've built up a no claims bonus and turned 25+, standard policies often become competitive without the restrictions. Industry data suggests the average telematics policy is held for 2.3 years.[1]

Black box car insurance, also called telematics insurance, uses technology to monitor how you drive and adjusts your premium based on your actual driving behaviour. A small device fitted to your car or a smartphone app tracks things like your speed, braking, acceleration, and the time of day you drive. Safe drivers can earn significant discounts, making it a popular choice for young and new drivers facing high premiums.
A black box uses GPS and motion sensors to track several aspects of your driving. It monitors your speed and whether you stay within limits, how smoothly you accelerate and brake, how you handle corners, and what time of day you drive. Most systems also track your total mileage and the types of roads you use. This data is sent to your insurer and used to calculate a driving score that affects your premium.
Safe drivers with black box insurance typically save between 20% and 40% compared to standard car insurance policies. For a 17 year old facing premiums of around £2,500, this could mean savings of £700 to £1,000 per year. The exact amount depends on how safely you drive and how well you score on speed, braking, and avoiding late-night driving. Poor driving scores may result in little or no discount.
Most black box insurers use a scoring system where higher scores mean better discounts. A score of 90 or above is typically considered excellent and earns the maximum discount of up to 40%. Scores between 75 and 89 are classed as good driving and earn moderate discounts of 15% to 30%. Scores below 60 are considered higher risk and may result in no discount or even a premium increase at renewal.
Yes, most black box policies allow you to drive at night, but journeys between 11pm and 5am are typically scored more harshly. This is because statistics show 40% of serious accidents involving young drivers happen during these hours. Some budget telematics policies have complete curfews during this time. If you regularly work night shifts or drive late, check the specific terms of any policy before buying.
Most black box policies include a mileage cap, typically between 7,000 and 10,000 miles per year. If you exceed your limit, you'll usually be charged for additional miles at a rate of around 10p to 20p per mile. Some insurers let you buy extra mileage upfront at a lower rate. Significantly exceeding your limit without paying could result in your policy being cancelled, so keep an eye on your mileage throughout the year.
For most young drivers, black box insurance is worth considering. Young drivers face the highest car insurance premiums in the UK, often between £2,000 and £3,000 per year. A telematics policy lets you prove you're a safe driver and earn discounts that wouldn't otherwise be available based on your age alone. Research shows telematics users also have 20% to 30% fewer accidents in their first year of driving.
Yes, the GPS in a black box means your insurer can see where you drive. However, UK insurers must comply with data protection regulations and can only use this information for calculating your premium and helping recover your car if it's stolen. Insurers cannot share your location data with third parties without your consent. If you're uncomfortable with location tracking, app-based telematics may feel less intrusive than a fitted device.
A black box is a physical device fitted to your car, usually behind the dashboard or in the diagnostic port. It works independently and doesn't require your phone. A telematics app uses your smartphone's GPS and sensors to monitor driving instead. Apps are more convenient because there's no installation appointment, but they require your phone to be charged and the app running while you drive. Some drivers find fitted devices more reliable.
