What happens if someone crashes your car?
If you lend your car and the borrower crashes it, what happens depends on how they were insured. Liability for the accident generally attaches to the person driving, not automatically to you as the owner. But if the claim runs through your policy, it can still cost you your no claims bonus, which is why how the borrower is covered matters so much.

Who is liable when someone else crashes your car?
In a road accident, responsibility for the crash itself generally attaches to the person who was driving, not automatically to you as the owner sitting at home. If the borrower causes the accident, they are the at-fault driver.
The important exception is insurance. You must not let someone drive your car unless they are properly insured to do so. Allowing an uninsured person to drive can expose you to a separate offence of permitting uninsured use, regardless of who was at fault in the crash. So the safe position is always to make sure the borrower is genuinely covered before they take the keys.
What happens to your no claims bonus?
This is where lending your car can quietly cost you. If the borrower is driving on your policy, for example as a named driver, then any at-fault claim is a claim on your policy and can reduce your no claims bonus, even though you were not behind the wheel.
That is the part owners do not expect: your bonus can take the hit for someone else's accident. Our guide to the no claims discount explains how the bonus works, and our guide on protecting your no claims bonus when lending covers how to keep it out of the firing line.
Will your insurer cover repairs to your own car?
Whether your own car is repaired depends on the level of cover and whose policy responds. If the borrower was on your comprehensive policy and at fault, your insurer would typically cover the repairs to your car, minus the excess, and your bonus would usually be affected.
If the borrower was driving on their own driving other cars extension, that cover is normally third party only, so it would pay for damage they caused to others but not for repairs to your car. That gap surprises a lot of owners, and it is a key reason to think about how a borrower is covered before lending.
Can you get in trouble if the borrower was uninsured?
Yes. This is the most serious risk. If you let someone drive your car when they are not insured to do so, you can face a penalty for permitting uninsured use, even though you were not the one driving. The penalties are the same as for driving uninsured yourself: up to £5,000 fine, six to eight penalty points, and a possible disqualification from driving. It is treated seriously precisely because the owner controls who gets the keys.
The way to avoid it entirely is to confirm the borrower has valid cover for your specific car before they drive. Do not rely on a vague assumption that they are "probably covered" by their own policy, as our guide on driving someone else's car explains.
How does a claim affect your next renewal?
Beyond the immediate no claims bonus impact, an at-fault claim on your policy is something you usually have to declare at renewal and on future quotes, typically for around five years. Insurers price on claims history, so a claim, even one caused by a borrower, can push your premium up.
This is why a single act of lending can have a longer tail than people expect. The accident may be over in a day, but the effect on your record and your premium can last for years if the claim went through your policy.
What to do straight after the accident
If someone crashes your car, the immediate steps are the same as for any accident. Make sure everyone is safe, call 999 if anyone is hurt or the road is blocked, and exchange details with any other party involved. As the owner, get the full account from the person who was driving as soon as you can.
Then tell your insurer, even if you are not sure whether you will claim, because most policies require you to report an accident within a set time regardless. Be clear about who was driving and how they were insured, as that determines whose policy responds. Keeping calm, factual records, photos, the other party's details and a written account of what happened, protects you whether the claim ends up on your cover or on the driver's own policy.
For the borrower, arranging daily car insurance before driving eliminates this risk entirely - it takes a few minutes to set up.
How temporary insurance protects you as the owner
The cleanest way to lend your car without putting your own policy at risk is for the borrower to take out their own short-term cover in their name. Then any claim from their driving runs through their policy, not yours, and your no claims bonus is untouched.
Temporary cover for lending your car is designed for exactly this. It keeps the borrower properly insured and the consequences of any incident with them, rather than with you. Just be sure they are not really the main driver of the car dressed up as an occasional one, which strays into fronting. Used honestly, short-term cover lets you lend your car with genuine peace of mind, knowing a mistake behind the wheel will not land on your record or your premium.
Frequently asked questions
If I lend my car and they crash it, am I liable?
Liability for the crash generally attaches to the driver, not automatically to you as the owner. The key risk for you is insurance: if you let someone drive uninsured, you can face a penalty for permitting it, regardless of who caused the accident.
Will a claim affect my no claims bonus even if I was not driving?
It can. If the borrower was driving on your policy, an at-fault claim is a claim on your policy and can reduce your no claims bonus. The way to avoid this is for the borrower to be covered by their own separate policy instead.
Will my insurer cover repairs to my own car?
If the borrower was on your comprehensive policy and at fault, your insurer would usually repair your car minus the excess. If they were driving on their own driving other cars extension, that is normally third party only and would not pay for your car's repairs.
Can I get in trouble if the borrower was uninsured?
Yes. Letting someone drive your car when they are not insured can expose you to a penalty for permitting uninsured use, even though you were not driving. Always confirm the borrower has valid cover for your car before handing over the keys.
How does a borrower's accident affect my renewal?
If the claim went through your policy, you usually have to declare it at renewal and on future quotes for around five years, and it can raise your premium. Keeping the borrower on their own cover avoids putting this on your record.
