Can you sue after a car accident in the UK?
Yes, you can sue someone for a car accident in the UK if they were at fault and caused injury, financial loss, or damage to your vehicle.
Most claims are resolved through insurance, but if liability is disputed or your losses are significant, legal action may be necessary.
In the UK, “suing” typically means pursuing a civil claim for compensation — not necessarily a dramatic courtroom battle. For most people, this process starts by reporting the accident to insurers and seeking medical treatment. But if the other party denies fault, refuses to cooperate, or isn’t insured, you may need to escalate.
This article walks you through when and how to bring a claim, what evidence you’ll need, and the role of legal professionals if things get complicated. We’ll also cover what happens if the other driver is uninsured or can’t be found — plus how long claims take, what you can be compensated for, and the risks involved.
When can you sue someone for a car accident?
You can sue someone after a car accident if they were at fault and you suffered injury, loss of earnings, or damage to your vehicle.
Claims must typically be made within 3 years of the incident.
Most car accidents are handled through insurance claims, but suing becomes necessary when the other driver:
- Denies responsibility
- Is uninsured or underinsured
- Causes serious injuries requiring long-term recovery
- Refuses to engage in the claims process
To succeed, you’ll need to show that the other party breached their duty of care and directly caused your losses. Whether it’s a whiplash injury, time off work, or costly repairs, you must be able to demonstrate how the accident impacted you — financially, physically, or both.
If you weren’t at fault (or were only partially responsible), you still have the right to seek compensation. In shared-fault scenarios, courts and insurers may apply split liability, meaning you could receive a reduced settlement based on your share of the blame.

Get QuotesHow do you prove fault in a car accident?
To sue someone successfully after a car accident, you’ll need evidence that proves they were responsible for the collision.
This includes witness accounts, photographs, and official reports.
Proving fault often starts at the scene. If you collected evidence — such as dashcam footage, damage photos, or a police report — you’re already ahead. Witness statements from passengers or bystanders can strengthen your case, especially if the other driver denies what happened.
Insurers typically assess fault using a combination of evidence, third-party accounts, and legal precedent (such as the Highway Code). If both drivers share blame, you may still recover compensation — but it will be reduced proportionally.
If liability remains unclear, a solicitor may bring in an accident reconstruction expert or rely on case law to argue your position.
How do you start the process of suing after a car accident?
To sue for a car accident in the UK, you typically begin by making a formal claim through the at-fault driver’s insurer. If that fails, you can pursue legal action in the civil courts.
Here’s how the process usually unfolds:
- Notify the at-fault driver’s insurer: Provide your version of events, any evidence collected, and details of your losses (medical costs, lost earnings, etc.).
- Try to settle out of court: Many claims are resolved without litigation, especially if liability is accepted and compensation agreed.
- Hire a solicitor (if needed): If the other party disputes fault or offers an unfair settlement, a personal injury solicitor can take over. Many work on a no win, no fee basis.
- Issue court proceedings: If settlement fails, your solicitor can file a claim in the county court. This begins the legal process, which may include mediation or a trial.
It’s important to act within the limitation period — usually 3 years from the date of the accident or injury diagnosis. If you’re suing on behalf of someone under 18, or someone lacking mental capacity, different rules apply.
What can you claim compensation for after a car accident?
You can claim compensation for personal injury, vehicle damage, lost income, medical bills, and other costs directly linked to the accident.
This includes both physical harm and financial losses.
Here’s a breakdown of typical compensation areas:
| Type of Compensation | Examples |
|---|---|
| General Damages | Pain, suffering, loss of mobility, reduced quality of life |
| Vehicle-Related Costs | Repairs, write-off payout, courtesy vehicle costs |
| Loss of Earnings | Time off work, future earnings if you can’t return to your job |
| Medical Expenses | Treatment, prescriptions, physiotherapy, rehabilitation |
| Travel Expenses | Journeys to medical appointments or legal meetings |
| Care or Assistance | Paid or unpaid help during recovery, such as home care |
How much you receive depends on the severity of your injuries and how the accident has affected your life long term. Minor injuries may result in modest payouts, while complex claims can run into thousands.
How long does it take to settle a car accident claim in the UK?
Most straightforward car accident claims settle within 6 to 9 months, but complex or disputed cases can take over a year.
The timeline depends on the severity of injuries and whether the other driver admits fault.
If liability is accepted early and medical recovery is relatively quick, insurers can agree on a payout within months. However, if there’s disagreement about what happened or how serious the injuries are, delays are more likely.
Claims involving court proceedings may take longer — especially if independent medical assessments, accident reconstructions, or negotiations are required. Your solicitor may also advise waiting until your condition stabilises to avoid under-settling.
Keep in mind:
- Minor claims with clear liability = fastest resolutions
- Serious injury or long-term recovery = extended timelines
- Denied liability = potential court delays
Being organised with evidence and responsive to solicitor queries can help speed things up.
Will you need a Solicitor to sue after a car accident?
Not always — but if your claim is complex, disputed, or involves serious injury, having a solicitor improves your chances of success.
For minor claims, especially where liability is accepted, you may be able to deal directly with the insurer using the Official Injury Claim (OIC) portal. It’s designed for straightforward personal injury claims under £5,000 (typically whiplash or soft-tissue injuries).
However, if any of the following apply, legal advice is recommended:
- The other driver denies responsibility
- You’re unsure how much you’re entitled to
- Your injuries are serious or long-lasting
- The claim value exceeds £5,000
- The insurer has made a low settlement offer
Most solicitors offer a “no win, no fee” arrangement, meaning you won’t pay legal fees unless your case succeeds. This can make legal action more accessible without upfront cost.
Final thoughts
Suing for a car accident in the UK is rarely the first step — but it can become necessary if insurers won’t settle fairly or the at-fault party denies responsibility. Knowing what you can claim, how the process works, and when to get legal support makes a big difference in achieving a fair outcome.
If you’ve been involved in an accident and need cover — whether to replace a written-off vehicle or to stay insured during legal proceedings — you may want to explore car insurance or temporary car insurance options tailored to your situation.
Taking calm, informed steps after an accident is the best way to protect your finances and your future mobility.
