If you’ve been involved in an accident, you may wonder: how long after an accident can you file a claim in the UK? It’s a critical question; getting the timing wrong could mean losing your right to compensation entirely. Knowing your legal time limits is essential, whether it’s a road traffic accident, workplace injury, or medical negligence.
In this guide, you’ll learn the statutory time limits for filing a personal injury claim in the UK, including Northern Ireland, and the exceptions that could affect your case. We’ll also walk you through the next steps so you don’t miss your chance to claim your debts.
At My Personal Injury Claim, we believe everyone deserves clear, reliable guidance on understanding the law and filing a claim in the UK. That’s why we make legal information easy to access and understand.
What Is the Time Limit for Filing a Personal Injury Claim in the UK?
Under the Limitation Act 1980, you generally have three years from the date of the accident to start legal proceedings for a personal injury claim in England and Wales. In Northern Ireland, the time limit is also three years, governed by the Limitation (Northern Ireland) Order 1989.
This three-year countdown starts from:
- The date of the accident, or
- The date you first became aware of your injuries being linked to someone else’s negligence is your “date of knowledge.”
Key Takeaway:
You have three years from the accident or from when you knew your injury was linked to negligence. If you miss this window, you may lose your right to claim.
Does the Time Limit Apply to All Types of Accidents?
The three-year limit applies broadly across most personal injury claims, including:
- Road Traffic Accidents
- Workplace Injuries
- Slips, Trips, and Falls
- Medical Negligence
- Dental Negligence
- Product Liability
However, some specific rules apply depending on your circumstances.
Exceptions to the Three-Year Rule
While the three-year rule is standard, there are important exceptions that could extend or reduce your timeframe.
1. Children (Under 18)
If the injured person was under 18 at the time of the accident:
- The three-year countdown doesn’t begin until their 18th birthday.
- A parent or guardian can file a claim on their behalf before then.
So, they have until their 21st birthday to claim.
2. Mental Capacity
If the injured person lacks mental capacity (due to brain injury, learning disability, or mental health conditions), the time limit may be paused until:
- They regain capacity, or
- A litigation friend acts on their behalf.

3. Fatal Accidents
If you’re claiming on behalf of a deceased loved one:
- You have three years from the date of death, or
- The date you knew their death was caused by negligence.

4. Criminal Injuries
If your injury resulted from a criminal act, you may need to file with the Criminal Injuries Compensation Authority (CICA):
- The time limit is two years from the incident.

Why You Shouldn’t Wait to Start Your Claim
Even if you technically have up to three years, you should act immediately. Here’s why:
- Evidence fades: Witness memories weaken, CCTV may be deleted, and documents can go missing.
- Quicker resolutions: The sooner you act, the faster your case may settle.
- Peace of mind: Starting early gives you confidence and control over the process.
Don’t delay. Speak to a personal injury solicitor when you suspect you have a valid claim.
How to Know If You’re Still Within the Time Limit
It’s not always obvious when your time limit began, especially in complex cases like medical negligence. You might only realise months or years later that a procedure caused you harm.
Here’s what you should do:
- Note the date of the incident.
- Get medical records—they can help identify your date of knowledge.
- Speak to a solicitor—they’ll calculate your deadline accurately.
What Happens If You File Late?
If you try to file a claim after your time limit, the defendant can ask the court to strike out your case. Unless you fall within an exception, your claim will likely be dismissed.
In rare cases, courts can allow out-of-time claims, but only where it’s fair and just—this is usually only granted in exceptional situations.
Don’t risk it. The earlier you act, the better your chances.
How to Strengthen Your Claim Before the Time Limit Runs Out
Once you understand how long after an accident you can file a claim, your next priority should be ensuring your case is as strong as possible. It’s not just about being on time—it’s about being prepared.
Here’s how you can build a compelling claim that improves your chances of success:
1. Understand the Full Impact of Your Injury
Don’t rush to claim before you understand the long-term effects of your injury. Some conditions—like whiplash or psychological trauma—can worsen over time. Keep track of:
- Ongoing medical appointments
- Prescription costs
- Time off work or lost earnings
- Emotional or psychological impact
This information will help your solicitor accurately calculate your total compensation.
2. Keep a Personal Injury Journal
Maintain a simple daily record that outlines:
- Pain levels
- Physical or mental struggles
- Restrictions on daily activities
- Missed events or personal milestones
This can serve as valuable evidence when demonstrating the injury’s effect on your quality of life.
3. Stay Off Social Media
Insurance companies and defence solicitors may monitor your online activity. A seemingly innocent photo or post could be used to suggest you’re less injured than you claim.
Stay cautious online until your case concludes.
4. Speak to a Specialist Solicitor Early
A specialist personal injury solicitor won’t just help you beat the deadline—they’ll help you build a solid, evidence-backed case to make a claim smoothly.
What a solicitor can do for you:
- Gather expert medical reports
- Liaise with insurers or employers
- Advise you on settlement offers
- Represent you if the case goes to court
You can search for personal injury solicitors in Northern Ireland via the Law Society NI Directory.
5. Watch for Delays That Could Cost You Time
Some delays are outside your control, such as waiting for medical reports or third-party responses. But others can be avoided if you act early.
Give yourself and your solicitor enough time to:
- Investigate liability
- Obtain necessary documents
- Explore alternative dispute resolution (ADR) where applicable
Waiting too long to start this process can leave you scrambling as the deadline approaches.
6. Know When to Settle—and When to Push Back
Some insurers may offer an early settlement, especially if they know you’re close to the time limit. But early doesn’t always mean fair.
A solicitor can assess whether the offer reflects your:
- Full recovery time
- Future care needs
- Ongoing financial loss
Settling too soon could leave you undercompensated. Don’t accept a low offer just to “get it over with.”
