Time limits for injury claims
in the UK
If you are thinking about making an injury claim, one of the most important things to understand is time limits. Many people miss out on compensation simply because they wait too long, often without realising there was a deadline.
This guide explains how long you have to make a personal injury claim in the UK, when the clock starts, the main exceptions and what happens if time runs out.
Quick Summary: Personal injury claim time limits
- Most personal injury claims must be started within 3 years.
- The 3-year period does not always start on the accident date.
- Different rules apply to children and industrial disease claims.
- You may still be able to claim even if you think it is too late.
- Starting a claim early protects your legal position.
What are time limits and why do they matter?
A time limit is the legal deadline for starting a compensation claim. If a claim is started after the time limit expires, it may be rejected even if the injury was clearly caused by someone else.
Time limits exist to ensure evidence remains reliable, to prevent unfair delays and to provide certainty for all parties involved. However, the rules are not as strict as many people assume and there are important exceptions.
The standard rule: The 3-year time limit
In most personal injury cases, you have 3 years to start a claim.
This time limit usually runs from:
- The date of the accident, or
- The date you became aware that your injury was linked to negligence.
This second point is known as the date of knowledge.
When does the clock actually start?
The clock does not always start on the day the accident happened.
This can apply if:
- You were injured but symptoms appeared later.
- Your condition worsened over time.
- You did not immediately realise what caused your injury.
In these situations, the 3-year time limit may begin from the point you reasonably became aware of both the injury and its cause.
Time limits for different types of claims
Accidents at work
The time limit is usually 3 years from the date of the accident. In some cases, it may run from the date of knowledge.
Road traffic accidents
You normally have 3 years from the date of the accident. This applies to drivers, passengers, cyclists and pedestrians.
Industrial disease claims
The time limit often starts from the date of diagnosis rather than the date of exposure. This is common for conditions that develop gradually over time.
Medical negligence claims
You usually have 3 years from the date the negligence occurred, or from the date you became aware that negligence caused your injury.
Time limits for children
If the injured person is under the age of 18, the usual time limit works differently.
The 3-year period does not start straight away. Instead, it begins on the child’s 18th birthday, meaning they usually have until their 21st birthday to make a claim.
A parent or guardian can still start a claim on their behalf at any point before then.
What if the injured person lacks mental capacity?
If someone lacks the mental capacity to manage their own legal affairs, the standard 3-year time limit may not apply.
In many cases, the time limit does not begin unless capacity is regained. These claims are complex and should always be assessed individually.
What happens if you miss the time limit?
If a claim is started outside the legal time limit, the defendant may ask the court to strike it out. This can mean compensation is no longer recoverable.
Although courts can allow exceptions, this is uncommon. This is why it is always better to check your position as early as possible.
Common mistakes people make with time limits
- Assuming the accident date is always the deadline.
- Waiting until recovery is complete before checking eligibility.
- Believing minor injuries do not qualify.
- Assuming it is too late without asking.
- Delaying because of worries about legal costs.
A quick claim check can help avoid all of these issues.
Does starting a claim mean going to court?
No. Starting a claim simply protects your position and stops the time limit from expiring.
Most personal injury claims are settled without a court hearing.
Does No Win No Fee affect time limits?
No. A No Win No Fee agreement only affects how legal costs are handled.
You must still start your claim within the legal time limit, regardless of how the claim is funded.
Frequently asked questions
What if I am not sure when my injury started?
This is very common. The date of knowledge can be assessed based on your circumstances.
Can I still claim if the deadline is very close?
Yes. Claims can often be started quickly to protect your position.
Does reporting an accident start a claim?
No. Reporting helps, but a formal claim must still be started.
What if the accident happened many years ago?
You may still be able to claim, particularly for industrial disease or delayed-onset injuries.
Should I wait until I recover before claiming?
No. Waiting can increase the risk of missing the deadline.
