What is black box car insurance?

Black box car insurance, also known as telematics car insurance, monitors your driving via a small device fitted to your vehicle or an app on your phone.

This allows your insurance provider to give you a personalised insurance quote based on your driving habits.

The safer your driving is, the lower your insurance premiums might be when you come to renew.

These types of policy are popular among younger and inexperienced drivers as they can potentially reduce premiums for a group often saddled with high costs. However, there’s no certainty they’ll lead to lower prices.

What does a black box do?

The black box device records a range of data about your driving, including:

  • Braking and acceleration

  • Speed

  • Cornering

  • Steering

  • Mileage

  • What time of day you drive

  • Where you drive

  • Number of journeys.

Some devices can also monitor whether you’re using your mobile phone while driving.

How does telematics car insurance work?

First, a black box device may need to be fitted to your car, either by yourself or an engineer. Alternatively, your provider may simply ask you to download a telematics app to your smartphone.

Once the device or app is installed, your provider will be able to collect a range of information about your driving habits using GPS and motion sensors.

How is a black box installed?

The process of fitting a black box depends on the type of policy you have...

Self-installed black box

You’ll be sent a small device to plug into your car or attach to your windscreen. You may need to pair it with a mobile phone app.

Engineer-installed black box

Your insurance provider will arrange for an engineer to install this device. It’s typically placed out of sight, often behind the dashboard, so it doesn’t distract you while you’re driving.

Smartphone app

Some insurance providers offer a telematics app that uses your smartphone’s GPS to gather data about your driving. You won’t need to have a device installed.

Who might black box car insurance be good for?

Is car insurance cheaper with a black box?

A black box could make your car insurance cheaper, but it depends on your age and how you drive. 

Safe and sensible drivers tend to be rewarded with the cheapest black box insurance. Reckless drivers, on the other hand, could face higher renewal premiums. 

The table below shows how much a typical telematics policy could cost by age:

How to get cheaper telematics insurance

There are a few things you can do to get cheap black box insurance quotes at renewal, including:

Improve your driver score

Follow your provider’s tips to become a safer driver.

Build up a no claims bonus

Every year you go without claiming on your car insurance could help you build your no claims discount. For example, drivers with 1-3 years’ no claims typically pay around £8224 less each year than those with zero years.

Watch your mileage

Spending less time behind the wheel could mean a cheaper quote.

Choose your car wisely

Choosing a vehicle in a lower car insurance group could mean you get access to cheaper cover. To give you an idea, you'll typically pay £5873 for a car with a 1-1.4L engine, compared to £9273 for an engine over 3L.

Park in a secure location

The black box can monitor where you park overnight. Choosing a safer location, like a garage or driveway, means your car is less likely to be stolen. Insuring a car parked on a driveway typically costs £3333, versus £6913 on a street outside your home.

Increase your excess

Agreeing to pay a higher voluntary excess could mean a lower black box insurance quote. But make sure you can afford the excess if you do need to claim.

Pay annually, rather than monthly

As with all car insurance, paying for the year upfront means you won’t be charged interest.

Compare quotes

Don’t go with the first price you see. Shop around to find the best black box insurance for your needs. You could save up to £4851 on your car insurance through Compare the Market.

How much does a telematics policy reduce insurance?

Some drivers, particularly young or high-risk drivers, could make significant savings by taking out a black box policy. 

You’ll also start to build up a no-claims discount if you stay claim-free thanks to your safer driving.

But having car insurance with a black box doesn’t guarantee you a cheaper quote. Your premiums could go up or down, depending on how you drive. 

Pros and cons of telematics insurance

Advantages

  • Potentially improved driving skills – get customised tips on how you can become a better driver through your insurance provider’s app on your phone

  • Rewards for safer driving – prove that you’re a safe and responsible driver, and you could get a cheaper quote when it’s time to renew your policy

  • Theft deterrence – the GPS technology in the black box can be used by police to find your car if it’s stolen

  • Evidence in an accident – if you’re involved in a crash, data from the black box can potentially be used to establish who was at fault. It could also speed up the claims process 

  • It’s arguably fairer – if you’re a safe driver, you’re not penalised because other drivers your age drive recklessly. 

Disadvantages

  • Stressful driving experience – the constant monitoring makes some drivers more anxious and diminishes their driving experience

  • Journey restrictions – driving at night can lower your driver score. So can going over your estimated mileage, potentially bumping up your premiums

  • Higher premiums for bad drivers – regularly driving fast and slamming on the brakes could mean you end up paying more for your car insurance

  • Less careful named drivers – most black box car insurance policies won’t be able to tell who is driving your car. If you add a named driver who drives poorly, it will be reflected in the driving score that shows on your policy, not theirs

  • Driver score not transferrable – insurance providers don’t share data on your driving. So, if you have a good record and switch to a different provider, you may have to build up your driving data again. 

Black box car insurance golden rules

If you stick to these basic black box car insurance principles, a telematics policy could work for you.

Remember, your score is based on your overall driving standard over a period of time. One-offs, such as braking hard to avoid a car that’s suddenly pulled out in front of you, shouldn’t affect your score.

Did you know?

According to government figures, ‘loss of control’, ‘exceeding the speed limit’ and ‘careless driving’ are more likely to be recorded in collisions involving younger drivers, compared with vehicles driven by motorists of other ages.

Is telematics car insurance right for me?

Many telematics policies are open to all ages and could benefit any driver who doesn’t have the best safety record.

Not only could they help save you money on your premium, they could also stop you from slipping into bad habits while behind the wheel.

But telematics car insurance won’t be right for everyone. Regular nighttime driving is likely to reduce your driving score. So, if you often work late shifts or drive your car overnight, it may not be the best option for you.

The number of miles you drive is a factor too. Black box car insurance might not be suitable for high-mileage motorists as more driving means greater risk. 

And if you share your car with another driver, they could bring down your score if they drive poorly.

What our expert says...

“There’s evidence to show that having a black box in the car can help drivers to be more aware and drive more safely. Plus, a telematics car insurance policy could be a cheaper option, and not just for younger drivers. Whatever your age, but particularly if you’re a new driver, it’s well worth comparing black box insurance quotes to see if a telematics policy is right for you.”

FAQs

What is a black box car?

A black box car is simply a vehicle that has a GPS tracking device fitted to it for insurance purposes. A black box can be fitted to most cars, regardless of the make or model.

However, depending on the provider and the black box they use, your car may have to be under 15-20 years old.

Can I see my black box data?

Yes, you typically need to log into an app or online portal to see data that’s been collected by your black box. 

This allows you to identify areas for improvement behind the wheel. Some providers will also encourage you to build streaks for safe journeys and achieve badges, as well as save money at renewal. Other policies may offer perks for safe driving, such as bonus miles or gift vouchers. 

Can I drive my car before the black box is installed?

Most insurance providers will let you drive your car while you wait for your black box to arrive. But it’s always best to check with your black box insurance provider first.

Bear in mind that you won’t build up a driver score until the box is fitted.

What happens if I get a bad score on my black box?

You’ll get a warning from your telematics car insurance provider if you repeatedly score badly or your driving is considered extremely dangerous.

If your score remains low, your premium may go up or your black box car insurance policy could be cancelled. This can make it much harder and more expensive to find another mainstream insurance provider.

How long do you need to have a black box for?

Black box car insurance policies last for 12 months. The black box will need to be installed for as long as your policy is active.

What happens if you go over your estimated mileage with a black box?

Driving more miles than you estimated when you took out your telematics policy usually leads to higher premiums. It doesn’t mean you’ll be fined or have your policy cancelled, as some people believe. 

Typically, your insurance provider will periodically check your mileage to see if you’re on track to meet your estimate. If it looks like you’re going to be over by more than a certain amount, they’ll usually contact you to say they need to raise your premium.

Check your telematics car insurance policy to see how it works for you.

Are there any specific eligibility criteria for black box car insurance?

Providers will likely have some eligibility criteria you need to meet to get a black box. This may include the car’s age, value and annual mileage.

Check the requirements when you compare black box insurance quotes and before you apply for a telematics policy.

Does telematics car insurance involve any extra costs?

There isn’t usually an extra charge for installing the black box. However, some providers will charge you if you miss the installation appointment. 

There may also be a charge for cancelling and disconnecting the device. And some black box insurance providers may charge you if you buy a new car and need to move the box. 

Will my telematics data be shared?

No, the information from your black box won’t be shared with a third party, except for the police.

And the police would only get access to your telematics data if they asked for it as part of a formal criminal investigation. In this case, legal permission would need to be in place to allow them to access it.

However, if you’re the named driver on a telematics insurance policy, the policyholder will be able to see your data and driving score. Something to bear in mind if you’re on your parents’ black box insurance.

Does a black box know if you crash?

The black box measures G-force, so it will recognise the impact force of a collision if you’re involved in an accident. It will also record:

  • How fast you were travelling at the time of the crash

  • Where the crash took place

  • What time the crash happened.

If you’re in a collision that wasn’t your fault, the information from your black box could be used as evidence to build a case in your favour.

Can I have a named driver with a black box policy?

You should be able to have a named driver added to your black box car insurance policy.

But the black box won’t know who is driving when, because it collects and records data on the car, not the driver. This means if you add a named driver who drives poorly, it will be reflected in the driving score that shows on your policy, not theirs.

There are some black box apps that allow you to assign journeys to named drivers on your policy. However, it’s important to be honest about this or it could invalidate your policy.

What happens to the black box after the insurance policy ends?

If you switch your insurance provider when your policy ends instead of renewing it, you can remove a self-fitted box yourself. You can then send it back or recycle it.

If you have a professionally fitted black box, your old provider will simply deactivate it so it no longer records your driving data. They may send someone out to remove it. If they don’t, you could choose to have it removed for a fee.

If I switch insurance provider, can I take my telematics data with me?

You can’t take data with you if you switch provider. And, in most cases, the black box itself can’t be transferred from one provider to another.

How is the black box removed?

If you have a professionally fitted black box, your insurance provider may arrange for someone to remove it. This is usually at a time that works for you and normally at a cost.

Don’t attempt to remove a professionally fitted black box yourself, unless you’re told to.

Do black boxes have curfews?

Some telematics policies used to have curfews to prevent people driving during later hours when accidents are more likely to happen. But they’re much less common these days.

That said, driving regularly in the dark could have a negative impact on your driving score which, in turn, could increase your premiums.

Can you have a black box at any age?

Some black box policies only cover motorists under 25, while others are open to all ages.

Do telematics devices record my conversations?

No, black box technology doesn’t record audio in your car. It only collects data on how, when and where you drive.
