If you have been injured at work, one of the most important questions to ask is:
“How long do I have to make a claim?”
Many people assume they can deal with a workplace injury when they feel ready — but personal injury claims in England and Wales are subject to strict legal time limits. If those deadlines are missed, you may lose your right to claim compensation entirely.
Understanding limitation periods is crucial. Even if your injuries seem manageable now, delaying legal advice can seriously weaken or prevent your claim.
This guide explains:
- The standard 3-year time limit
- What “date of knowledge” means
- Exceptions to the rule
- Why acting early protects your case
The 3-Year Rule
In most accident at work claims, you have three years to issue court proceedings.
The three year period runs from:
- The date of the accident; or
- The “date of knowledge”
This rule is set out in the Limitation Act 1980 and applied to most personal injury claims.
It is important to understand that simply contacting a solicitor is not enough. If a claim has not been settled, formal court proceedings must be issued within the limitation period to protect your right to compensation.
What is the "Date of Knowledge"?
The “date of knowledge” applies when your injury is not immediately obvious.
This is common in cases involving:
- Repetitive strain injuries
- Hearing loss
- Exposure to hazardous substances
- Work-related respiratory conditions
- Industrial diseases
The limitation period begins when you first knew – or ought reasonably to have known – that:
- You were suffering from significant injury; and
- The injury was attributable to your work
This can sometimes be years after exposure occurred.
Because this area of law can be complex, specialist advice is particularly important in industrial disease claims.
Exceptions to the 3-Year Rule
There are several important exceptions.
Children
If the injured person is under 18 at the time of the accident:
- The three-year limitation period does not begin until their 18th birthday
- They therefore usually have until their 21st birthday to bring a claim
A parent or litigation friend may bring a claim on their behalf before they turn 18.
Mental Incapacity
If an injured person lacks mental capacity (within the meaning of the Mental Capacity Act 2005):
- The limitation period may not apply while incapacity continues
If capacity is later regained, the three year period may begin from that point.
Can the Court Extend the Time Limit?
In limited circumstances, the court has the discretion to allow a claim to proceed outside the standard three-year period.
However:
- This is not promised
- The burden is on the claimant
- Delay must be justified
- The court will consider whether a fair trial is still possible
Relying on discretion is risky. It is always safer to seek advice well before limitation expires.
Why You Should Not Delay
Even though you may technically have three years, waiting can seriously weaken your claim.Our guide on what to do immediately after an accident at work explains why early action is so important.
Over time:
- Evidence fades
- CCTV footage is erased (often within weeks)
- Witnesses leave employment
- Employers change management
- Documents are lost
- Recollections become unreliable
Early legal advice allows your solicitor to:
- Secure evidence quickly
- Preserve documentation
- Request accident reports
- Obtain medical evidence promptly
- Protect your position before deadlines approach
The earlier you act, the stronger your case is likely to be.

Frequently Asked Questions
Can I claim if the accident was partly my fault?
Yes. Even if you were partly responsible, you may still receive compensation under contributory negligence principles.
Your compensation may be reduced to reflect your share of responsibility, but you are not automatically prevented from claiming. Employers still have a legal duty to provide a safe working environment.
What if the accident wasn't recorded in the Accident Book?
You can still bring a claim.
While accident book entries are helpful evidence, they are not essential. Medical records, witness statements, CCTV footage and photographs can all support your case.
It is advisable to notify your employer in writing as soon as possible if the incident was not formally recorded.
How long do I have to make an accident at work claim?
In most cases, you have three years from the date of the accident to start court proceedings. You can read a detailed guide on accident at work time limits and how long you have to claim.
If your injury developed over time (for example, repetitive strain injury), the three year period may begin from the date you became aware that your condition was work-related.
There are exceptions for children and individuals lacking mental capacity.
Can my employer dismiss me for making a claim?
No. It is unlawful for an employer to dismiss or treat you unfairly for pursuing a legitimate personal injury claim. You can read more about your rights in our guide on being sacked for making an accident at work claim.
If your employer takes adverse action against you because you exercised your legal rights, this may amount to unfair dismissal or victimisation.
Will claiming compensation affect my job?
Most workplace accident claims are handled by the employer’ liability insurance.
The claim is made against the insurer – not directly against your employer personally. Professional employers understand that insurance exists for this purpose.
