How usage-based car insurance actually works in the UK
Usage-based car insurance is an umbrella term for two different products that are often marketed as if they were the same thing. They are not, and confusing them is the main reason people end up disappointed at renewal.
The first is pay-per-mile. Your premium splits into a fixed base rate that covers the car while it is parked, plus a variable charge for every mile driven — typically 2p to 10p per mile depending on risk profile. Mileage is tracked by a plug-in OBD-II device, a self-install box, or a smartphone GPS app. There is no driving-style score. Drive 3,000 miles carefully or 3,000 miles badly and you pay the same per mile.
The second is pay-how-you-drive telematics. A black box or phone app records speed, braking force, cornering, acceleration, and time of day, then converts that into a driving score, usually out of 100[reference:2]. A high score keeps your premium where it started or reduces it at renewal; a low score can push it up or, in the worst cases, lead to the policy being cancelled.
Both are fully comprehensive and FCA-regulated. Both can save money. But they reward completely different behaviours, which is why the "best app" question cannot be answered without first asking how you drive.
The best usage-based car insurance apps compared (2026)
| Provider | Model | How it tracks | Best for | Night policy |
|---|---|---|---|---|
| By Miles | Pay-per-mile | App or plug-in device | Low-mileage drivers, second cars, remote workers | No restriction; night miles at same rate |
| Cuvva | Pay-per-mile + short-term cover | Smartphone app | Infrequent drivers, borrowing a car, temporary cover | No telematics score |
| Zego Sense | Driving-score telematics | App only, no hardware | Everyday drivers, new drivers, van owners | Score-based, no hard block |
| Hastings Direct YouDrive | Driving-score telematics | App + keyfob-sized tag | Drivers who want no fitted black box | Score penalty only, 11pm–6am[reference:6] |
| Marmalade | Driving-score telematics | Black box + app | New and young drivers | No curfew; score penalty only |
| Admiral LittleBox | Driving-score telematics | Professionally fitted device | Drivers who want a big-brand structured policy | Score penalty only, 11pm–5am |
| Ticker | Pay-per-mile + driving score | Plug-in mile tracker | Low-mileage drivers who also want score feedback | No hard curfew |
| LV= Pay By Mile | Pay-per-mile | App-based | Drivers who value a mainstream insurer with strong claims service | No telematics score |
Provider terms change frequently. Always read the current Key Facts Document (KFD) for the specific product before buying — comparison summaries and forum posts often refer to older versions of the same policy.
By Miles — best for low-mileage drivers
By Miles was the UK's first pay-per-mile insurer and remains the cleanest implementation of the model. You pay a fixed annual cost that covers the car while it is parked, then a per-mile rate — typically 3p to 10p per mile for a standard private car — for actual usage. The app shows the exact cost of each day's driving, which makes budgeting unusually transparent. There is no driving-style score at all, which is either the biggest advantage or the biggest drawback depending on what you wanted.
Who it suits: retired drivers, remote workers, second-car owners, city residents, and anyone consistently below 6,000 miles a year. Who it does not suit: drivers who want to be rewarded for smooth driving rather than simply for driving less.
Zego Sense — best app-only telematics policy
Zego Sense runs entirely through a phone app with no hardware to fit. It tracks cornering, acceleration, and braking, and shapes your renewal price around how well you drive. Published pricing starts from around £578.51 a year, close to the UK average comprehensive premium, and Zego claims 96% of Sense drivers paid less at renewal than their initial premium — though that is a provider-published figure, not independent data.
Zego is also one of the few providers offering seamless cover across personal and business use, which matters for delivery drivers and tradespeople. Worth noting: Trustpilot sentiment on Zego Sense is genuinely mixed, with some reviewers reporting renewal quotes that did not reflect a good in-app score. Read recent reviews rather than marketing pages.
Hastings Direct YouDrive — best for no hardware at all
YouDrive is app-based with a keyfob-sized tag that pairs with your phone, so there is no black box fitted to the car. It is backed by a large, established insurer and often comes in as one of the cheapest entry prices for under-26 drivers — one Forbes comparison found a YouDrive policy at £719.02, or £68.29 upfront followed by 11 monthly payments of £65.96. Night driving between 11pm and 6am produces a score penalty but no journey block or per-trip fee.
Watch for: the app relies on your phone tracking trips accurately. Harsh braking and speeding directly cost you money under score-based pricing.
Marmalade — best for new and young drivers
Marmalade's telematics policy is built specifically around new and young drivers, recording behaviour over time and using it to adjust premiums while giving feedback that helps build confidence. Crucially, there is no night curfew — night miles between 11pm and 6am reduce your score but do not block travel or trigger a per-journey fee. Parents insuring a child's car can also get behaviour alerts, which is a genuine differentiator for learner and newly qualified motorists.
Admiral LittleBox — best traditional black box
LittleBox uses a professionally installed device rather than an app, which appeals to drivers who want the established, structured version of telematics. Night miles between 11pm and 5am lower your monthly score but are permitted, with no journey block and no per-trip fee. It is a reasonable fit for younger drivers who want to prove a safety record with a well-known brand and unlock better renewal pricing.
Ticker — best pay-per-mile with score feedback
Ticker blends the two models: a plug-in mile tracker bills you monthly for the miles you actually drive, while the app also shows a driving score for new-driver, older-driver, convicted-driver and van policies. It is a useful middle ground for low-mileage drivers who still want feedback on how they are driving, and the app handles quotes and policy changes directly].
Cuvva — best for genuinely occasional driving
Cuvva is less a traditional annual policy and more a flexible cover app. It started with short-duration cover sold by the hour, day or week, and now also offers a cancellable monthly subscription model[reference:29]. For drivers who borrow a car occasionally, or who need cover for a few days a month rather than a full year, it can be dramatically cheaper than any annual policy. For someone driving regularly, it usually is not.
Pay-per-mile vs driving-score apps: which saves more?
The honest answer is that they are optimised for different people, and the wrong choice can cost you money even if the app itself is well built.
| Your situation | Better model | Why |
|---|---|---|
| Drive under 6,000 miles/year | Pay-per-mile | You pay for what you use; driving style is irrelevant to the bill |
| Drive 6,000–8,000 miles/year | Either — run both quotes | You sit on the break-even line; the better driving score may tip it either way |
| Drive over 10,000 miles/year | Driving-score telematics or standard cover | Per-mile billing stops being cost-effective above roughly 8,000–10,000 miles |
| New or young driver | Driving-score telematics | Telematics can cut the day-one premium by 30–50% for 17–24 year olds versus standard cover |
| Confident, smooth driver with a long commute | Driving-score telematics | Your behaviour is the asset being priced; a high score compounds at renewal |
| Shift worker driving at night | Pay-per-mile, or check the night policy carefully | Most score-based policies penalise 11pm–6am miles; pay-per-mile usually does not |
One real-world illustration: a retired driver covering 3,200 miles a year paid £624 on a standard comprehensive policy, then switched to By Miles and paid £164 in base premium plus £148 in mileage charges — a total of £312, saving £312 without changing how she drove. That is the pay-per-mile case in one paragraph. It does not mean a 22-year-old doing 12,000 miles a year would see anything similar.
The night-driving rule nobody reads until it costs them
Almost every telematics provider treats late-night miles as higher risk. What differs is how they enforce it, and the gap between the two approaches is large enough to change which policy you should buy.
A hard curfew is a formal contractual restriction, typically between 11pm and 6am, written into the policy schedule and KFD. Breach it enough times and the insurer charges a per-journey night fee (usually £5–£10 per trip), issues a written warning, or moves toward cancellation. A score penalty is different: night miles simply earn fewer score points, your monthly score falls, and a low enough score raises your renewal premium — but you are never stopped from travelling and no fee arrives per journey.
In 2026, most major UK providers have moved to score penalties rather than hard curfews. Admiral LittleBox, Marmalade, Hastings YouDrive and ingenie (AXA) all use score penalties with no journey block or per-trip fee. By Miles has no restricted hours at all, because it does not score driving style — night miles cost the same per-mile rate as daytime miles.
Data, privacy, and what the app actually tracks
Usage-based insurance requires you to hand over driving data, and it is worth being clear about what that means before you install anything.
- Location and time. Telematics apps record where and when you drive, which is inherently sensitive.
- Phone sensors. App-only products like Zego Sense use phone accelerometers and GPS to detect journey start and end, braking, cornering and acceleration. Zego states that Sense is designed to avoid scoring journeys that clearly are not you driving, and to let you correct trips that look wrong.
- Battery and reliability trade-offs. App-only tracking drains phone battery, and poor GPS signal in some areas can mean lost mileage credit.
- Score disputes. If a score looks wrong, use the app's correction or dispute route early. Several of the negative reviews across providers stem from scores the driver believed were inaccurate and did not challenge in time.
- Data retention and sharing. Check the privacy notice for how long driving data is kept and whether it is shared with reinsurers or analytics partners. This is standard practice but varies by provider.
None of this is a reason to avoid the category. It is a reason to read the privacy notice the way you read the excess — quickly, before you buy, not after.
How to choose the right app for your driving
- Calculate your real annual mileage. Use your last MOT or service record, not a guess. The break-even sits around 6,000–7,000 miles.
- Decide whether you want to be priced on distance or behaviour. These are different products. Do not buy a driving-score policy hoping it behaves like pay-per-mile.
- Check the night policy against your actual schedule. Shift workers should prioritise pay-per-mile or a no-curfew score-penalty provider.
- Run at least three quotes. Compare a standard policy, a pay-per-mile quote, and a telematics quote for the same car and details.
- Read the KFD for excess, courtesy car, and telematics terms. Headline premium is the least informative number on the page.
- Check the app's recent reviews, not its marketing page. Score disputes and renewal surprises show up in reviews long before they show up in comparison tables.

Frequently asked questions
What is the best usage-based car insurance app in the UK for 2026?
For low-mileage drivers, By Miles is the strongest pay-per-mile option. For app-only driving-score telematics, Zego Sense and Hastings Direct YouDrive lead. For new and young drivers, Marmalade is the best fit, particularly because it has no night curfew.
Is pay-per-mile car insurance cheaper than a standard policy?
It usually is below roughly 6,000–7,000 miles a year, with typical savings of £150–£400 annually against standard comprehensive cover. Above about 8,000–10,000 miles it generally stops being cost-effective.
How much does telematics car insurance cost in the UK?
UK telematics policies typically range from around £460 to £1,600 a year depending on driver age, vehicle, postcode and product. Zego Sense personal car pricing starts from around £578.51.
Do usage-based insurance apps track me at night?
Yes, most record time of day. In 2026 the majority use a score penalty for 11pm–6am miles rather than a hard curfew, but some products still carry formal night restrictions. Check the Key Facts Document for the specific policy.
Can I get usage-based insurance without a black box?
Yes. Zego Sense is app-only with no hardware, Hastings Direct YouDrive uses a phone app plus a keyfob-sized tag rather than a fitted box, and By Miles works through an app or a plug-in device.
Does driving badly actually increase my premium?
Under score-based telematics, yes. A low score can raise your price at renewal or, in the worst cases, lead to the policy being cancelled at a monthly check. Below 60 usually triggers warnings and below 40 can mean cancellation.
Is telematics insurance good for young drivers?
It is one of the most effective ways to reduce a first-year premium. For 17–24 year olds, telematics typically cuts the day-one premium by 30–50% versus standard cover, and a black box policy is the cheapest quote on the UK market roughly 70% of the time for 17–19 year olds.
What happens if the app loses GPS signal?
You can lose mileage credit in poor-signal areas, which is a known limitation of app-based tracking. Plug-in devices are less affected, and most apps let you review and dispute trips that look wrong[reference:54].
