Do You Need Insurance for Each Borrowed Car?

Fact Checked

It depends on your policy. If you have driving other cars (DOC) cover, you have basic third-party protection on any car you borrow with the owner’s permission.

If you do not have DOC, you need to arrange cover for each vehicle separately before you drive it.

Most drivers assume their car insurance lets them drive any car they borrow, but it almost certainly does not.

DOC cover used to be standard on comprehensive policies, but as of 2025 only around 2% include it.

If you regularly borrow cars from friends or family, you need to know what your policy actually covers and what your options are when it falls short.

Key Takeaway

Almost certainly, yes. Driving other cars cover used to be standard and now sits on a small minority of comprehensive policies — and where it survives it is third party only, so damage to the borrowed car is on you. Read your certificate rather than assuming. For occasional borrowing, short-term cover in your own name is usually cheaper and safer than being added as a named driver.

What is driving other cars cover and how does it work?

DOC is a feature on some comprehensive policies that lets you drive vehicles you do not own, with the owner’s permission. It provides third-party only cover, which is the legal minimum required to drive on UK roads.

What does third-party only actually mean for the borrowed car?

It covers damage you cause to other people’s vehicles, property, and injuries to third parties. It does not cover damage to the car you are borrowing.

If you crash your friend’s car while driving on DOC, their vehicle is not protected by your policy. You would need to pay for the repairs yourself unless the owner’s own policy covers the damage.

Does your policy include DOC cover?

Probably not. The ABI has noted the steady decline in DOC cover across the UK motor insurance market, and it is never available on third-party or third-party fire and theft policies.

How do you check?

Look at your certificate of motor insurance, not your policy schedule. If DOC is included it will be listed there, so do not assume you have it just because you pay for comprehensive cover.

Even if your policy does include DOC, there are usually restrictions. Common ones include age limits (often 25 and over), UK-only driving, emergency use only, and the requirement that your own car is still available and not written off.

Some policies also restrict DOC to cars within a certain engine size or insurance group. If you borrow a high-performance car, your DOC clause may not apply even if it covers you on smaller vehicles.


What are your options if you do not have DOC?

Three routes: temporary insurance for the borrowed car, being added as a named driver on the owner’s policy, or the owner adding you to their policy as a temporary driver.

How do the options compare?

Option Cover level Typical cost Best for Impact on owner’s policy
DOC (if included) Third-party only No extra cost Emergency or one-off drives None — but damage to their car is not covered
Temporary insurance Comprehensive £10 to £50 per day Occasional borrowing from different people None — standalone policy, no claims connection
Named driver on owner’s policy Same as owner’s cover £15 to £30 admin fee + premium increase Regular borrowing of the same car Premium may increase and any claim affects their record
Owner adds you temporarily Same as owner’s cover Admin fee (varies by insurer) Short-term regular use of one car Same as named driver — linked to owner’s policy

Temporary car insurance is the most flexible option for most borrowing situations. You can arrange it in minutes, it provides comprehensive cover, and it keeps the owner’s policy and no-claims discount completely separate.


When does each option make financial sense?

The cheapest option depends on how often you borrow, whether it is always the same car, and how long each borrowing period lasts.

What if you borrow different cars occasionally?

If you borrow two or three different cars a year for a few days each, temporary insurance for each borrowing is the most cost-effective approach. From the owner’s side the position is the mirror image: their policy covers the drivers named on it, not whoever happens to borrow the car.

What if you borrow the same car regularly?

If you borrow your partner’s or parent’s car every week, being added as a named driver on their policy is almost certainly cheaper. The additional premium is typically modest, and you are permanently covered without arranging anything each time.

What happens if you drive a borrowed car without insurance?

Under the Road Traffic Act 1988, driving without valid insurance is a criminal offence. The fixed penalty is £300 and 6 penalty points, and in court the fine is unlimited with possible disqualification.

What are the consequences for the car owner?

The owner can also face prosecution for permitting uninsured driving if they knowingly allowed you to drive without valid cover. Their own policy could be voided if the insurer considers it a breach of the policy terms.

If you cause an accident while uninsured, the Motor Insurers’ Bureau pays the third-party costs but then recovers them from you personally. In serious injury cases, this can run into hundreds of thousands of pounds.

Police can also seize the vehicle on the spot. Recovery and storage fees typically cost £150 to £350, and if the car is not reclaimed within a set period it can be crushed.

How can you keep costs down when borrowing regularly?

If you frequently borrow the same car, a named driver arrangement on the owner’s fully comprehensive policy is almost always cheaper than buying temporary cover each time.

What about multi-car policies?

Some insurers offer multi-car discounts if two or more cars in the same household are insured on the same policy. If you and the car owner live at the same address, this could reduce the cost for both of you.

Multi-car policies typically offer a 10% to 15% discount on each vehicle. They also simplify administration because both cars are managed under a single account with one renewal date.

If you are borrowing from someone outside your household, temporary insurance remains the simplest option. It avoids any complications with the owner’s policy and keeps the two of you financially separate if there is a claim.

Always confirm with the owner that they are happy for you to drive their car, regardless of which cover route you use. Even with DOC or temporary insurance in place, you need the registered keeper’s explicit permission before driving their vehicle.

Frequently Asked Questions (FAQs)

Does comprehensive insurance automatically include DOC cover?

No, DOC used to be common on comprehensive policies but only around 2% now include it. Check your certificate of motor insurance to confirm.

What does DOC cover actually protect?

Third-party only, covering damage you cause to other people’s vehicles, property, and injuries to third parties. It does not cover damage to the car you are borrowing.

Can I buy DOC cover as an add-on?

Generally no, because DOC is either included in your policy or it is not. If you need cover to drive other cars, temporary insurance is the practical alternative.

Will using DOC cover affect my no-claims bonus?

If you make a claim while driving on DOC, it could affect your no-claims discount on your own policy. Temporary insurance keeps any claims separate from your main policy.

Is temporary insurance better than DOC?

For most borrowing situations, yes. Temporary insurance provides comprehensive cover and protects both you and the borrowed car, while DOC only covers third-party damage.
