If your car was hit by someone else and the accident was not your fault, the law says you should be put back in the position you were in before the crash. In practical terms, that means a replacement vehicle while yours is off the road.
It sounds simple, and most of the time it is. The complications come from three short phrases that get thrown around without much explanation. Like-for-like. Reasonable period. Mitigation.
Here is what each one actually means, and how to use them to protect yourself.
Like-for-like
Like-for-like means the replacement vehicle should be genuinely equivalent to the one that was damaged. That is not a vague invitation to give you anything with four wheels.
In real life, like-for-like considers:
- Vehicle class. A small hatchback is not equivalent to a family SUV. A diesel transit is not equivalent to a hatchback. The class of the replacement should match the class of your own car.
- Transmission and fuel type. If you only hold an automatic licence, you get an automatic. If you drive an EV and have no off-street petrol arrangement, an EV makes sense.
- Practical needs. If you carry equipment for work, the replacement needs to carry it too. If you have a child seat and a wheelchair, the replacement needs the space.
The phrase you will see in the General Terms of Agreement (GTA) and case law is "broadly equivalent". You are not entitled to a fancier car. You are entitled to one that lets you live the same way you did before the accident.
If a courtesy car turns up that is two classes smaller than your own, you do not have to accept it. Politely decline and call a credit hire provider that can deliver an actual like-for-like.
Reasonable period
You are entitled to a replacement vehicle for the period you genuinely need one. Not longer. Not shorter.
That period usually covers:
- The time your car is being inspected and assessed
- The time it spends being repaired
- The gap between a total loss decision and the insurer paying out, so you can buy a replacement
A reasonable period is the time the process should sensibly take, given the damage and the repairer's capacity. If your repair was always going to take two weeks, two weeks is reasonable. If the repairer has held the car for six weeks because the bumper is on back-order from Germany, that delay is not down to you, and the period extends.
What is not reasonable is keeping the hire vehicle for an extra fortnight because it is nicer than your own. The insurer will challenge it. The provider should never let it happen.
Mitigation
Mitigation is the legal duty to keep losses down. In a credit hire context, it means doing what a reasonable person would do to limit the cost of the claim.
That sounds dramatic. In practice it is common sense.
- Get the repair under way quickly. Do not sit on a damaged car for three weeks before booking it in.
- Use the replacement vehicle for what you used your own car for. Not for taking the family on a holiday to Cornwall.
- Return the vehicle when you no longer need it. When your car comes back, the hire vehicle goes back.
- Be honest about whether you actually need a replacement. If you have not driven your car in a week, "need for hire" is going to be a harder argument.
A good credit hire provider will help you mitigate. They should ask about your daily use, set sensible expectations, and prompt you when the hire period should end. The bad ones leave the car on your drive until the at-fault insurer challenges it.
Need for hire
Underneath all three phrases sits one question. Did you actually need a replacement vehicle?
If the answer is yes, you have a strong claim. If the answer is "not really, but a free car would be nice", credit hire is not the right route.
Ask yourself:
- Do I use my car for work, the school run, medical appointments, or caring duties?
- Do I have any other vehicle I could reasonably use?
- Is public transport a realistic substitute?
If you have a need, document it. Two lines is enough. "I use my car to drive to work in Macclesfield five days a week. The journey takes 30 minutes by car and 90 minutes by bus." That is the kind of clarity that settles a claim quickly.
What this means in practice
You are not at the mercy of the at-fault insurer. You have a legal right to a like-for-like replacement, for a reasonable period, while you mitigate sensibly.
If you take that right seriously, document your need, and choose a credit hire provider that runs cases properly, the system works the way it was designed to. You stay mobile. The provider recovers the costs. The at-fault insurer pays a fair bill.
