What Is A Non-Fault Accident?

A non-fault accident is usually an accident where you were involved but are not treated as legally responsible for causing it, so another driver or party may be liable for the damage and losses.

If you have just had a crash, the important first steps are staying safe, getting the other driver’s details, collecting evidence where you can, and understanding how insurers decide fault before repairs, recovery or other support move forward.

This is general information only, not personal insurance advice. Policy wording and insurer practice varies.

What Is A Non-Fault Accident and How Does It Affect My Insurance?

A non-fault accident usually means you were not the person who caused the crash, and liability is accepted by another party or their insurer.

The key point is this: insurers do not label a claim “non-fault” just because you feel blameless.
They normally treat it as non-fault when liability is accepted and, in many cases, when costs are recovered from the other side.

Here is a quick snapshot:

What Is the Difference Between a Fault and a Non-Fault Claim?

Understanding Fault Claims and Liability

A fault claim is where you’re found responsible, or where responsibility can’t be proven against the other side, so your insurer ends up paying out without full recovery.

A non-fault claim is where another driver or party is responsible, and your insurer may pursue their insurer to recover costs such as repairs, hire charges or other outlays, depending on the circumstances.

In the UK, you’ll still usually have to declare any accidents/claims when you get quotes, including non-fault ones. (Compare the Market)

How Non-Fault Accidents Are Determined

Insurers usually decide fault by looking at evidence such as:

• Photos of damage and the scene
• Dashcam footage (often a game-changer)
• Witness details
• Police reference numbers or reports (where applicable)
• Consistency between statements and vehicle damage patterns

Sometimes liability is clear, for example with many rear-end shunts.
Other times it is less straightforward, and you might see split liability, such as 50/50, if both sides are considered partly responsible.

When Your Insurer Investigates Whose Fault It Was

Once you notify your insurer, they will usually ask for your version of events and any proof you have.
They may also contact the other insurer and try to get liability agreed.

If liability is disputed, it can take longer, and some outcomes, such as an excess refund or your NCD position being confirmed, may not happen until recovery is settled.

Will a Non-Fault Claim Affect My Insurance Premium?

How Non-Fault Claims Affect Insurance Costs

This is the part many people find frustrating: a non-fault claim can still push up premiums, even when you did nothing wrong.

Many insurers rate you as a higher risk if you have been involved in any incident, because their pricing models use claims history as one factor. Price comparison guidance is clear on this point. (Compare the Market)

So, yes, it can feel unfair.
But it is common.

Impact on Your No Claims Discount and NCD Protection

In many cases, if you are not at fault and the insurer recovers the money, your NCD is not reduced. (Admiral)

If you have paid for NCD protection, that usually protects the discount level, but it does not mean your total premium cannot rise. (MoneySavingExpert.com)

So NCD protection can help, but it is not a complete shield against pricing changes.

Why the Cost of My Car Insurance May Still Increase

Even if all costs are recovered, insurers may still factor in:

• You’ve had “an incident” on your record (even non-fault)
• The type of incident (minor bump vs multi-vehicle)
• Claim size (repairs + hire car can add up fast)
• Your postcode, mileage, vehicle group, and wider market pricing

That is why two people can have the same “non-fault” outcome but see very different renewal prices.

What Happens When You Make a Non-Fault Accident Claim?

The Car Insurance Claim Process for Non-Fault Accidents

A typical non-fault accident claim may involve these stages:

1. You report the incident (even if you’re unsure you’ll claim)
2. Your insurer opens a file and asks for details/evidence
3. Liability is discussed with the other insurer
4. Repairs and (if included/eligible) a courtesy car are arranged
5. Costs are recovered from the at-fault insurer where possible

Some claims are resolved quickly.
Others take longer, especially if liability is disputed or further evidence is needed.

How Your Insurer Can Recover the Costs from Another Driver

Behind the scenes, your insurer will usually try to recover outlay via a process often referred to as subrogation.

If the other side’s insurer accepts fault, recovery can be relatively straightforward.
If not, it can involve negotiations, evidence requests and sometimes legal action.

Repair or Replacement: What Your Insurance Policy Covers

Whether your car is repaired or written off depends on:

• The damage severity
• Repair cost vs pre-accident value
• Your insurer’s thresholds and engineer report

If it is written off, the insurer normally settles based on market value just before the crash.
If you disagree, you can raise evidence such as comparable listings and service history.

Can I Claim Compensation After a Non-Fault Accident?

Claiming for Personal Injury and Vehicle Damage

Vehicle damage is usually handled through insurers, repair networks or approved repairers, depending on the policy and claim route.

Personal injury is often handled separately, and usually needs:

• Medical evidence
• Proof of losses (time off work, travel, care costs)
• A clear link between accident and injury

If you think you may be injured, getting checked by a medical professional is important for your wellbeing and can also create a clear record of what happened.

How to Claim When Involved in an Accident with an Uninsured Driver

If the other driver is uninsured, your insurer may still be able to help, especially if you have comprehensive cover, but recovery can be more complicated.

This is where the Motor Insurers’ Bureau (MIB) often comes in for compensation routes for uninsured or untraced drivers. (mib.org.uk)

Using the MIB to Recover Costs from At-Fault Parties

The MIB has different routes depending on the situation (uninsured vs untraced/hit-and-run). Their guidance covers time limits and how claims are assessed. (mib.org.uk)

One detail worth knowing: under MIB schemes, property damage claims can involve a £300 excess in certain circumstances, depending on which agreement applies. (mib.org.uk)

How Does a Non-Fault Accident Affect My No-Claims Bonus?

Protecting Your Claims Discount After a Non-Fault Insurance Claim

Practical ways to protect your position include:

• Get as much evidence as you can at the scene (photos, dashcam, witnesses)
• Report promptly and keep your story consistent
• Keep receipts for any out-of-pocket costs
• Ask your insurer how they treat NCD while recovery is ongoing

Insurers often treat NCD as protected once liability and recovery are confirmed, but timelines and policy wording vary.

Will Another Claim in the Future Impact My NCD?

Another claim can increase the chance of higher pricing, even if it is non-fault again.

Most insurers also ask about incidents or claims over a set period, often several years, so multiple claims in a short window can make shopping around harder.

What Should I Do If I’m Involved in a Non-Fault Car Accident?

Steps to Take When Another Vehicle Causes an Accident

At the scene, when it is safe:

• Check injuries and call emergency services if needed
• Take wide and close-up photos (cars, plates, road layout, signage)
• Get names, addresses, phone numbers, insurer and policy details
• Collect witness contact details
• Don’t argue fault at the roadside, and avoid wording that sounds like an admission

Afterwards:

• Notify your insurer as soon as you reasonably can
• Keep a log of calls, emails, dates, names, and what was agreed

How Your Insurance Company and Insurance Provider Investigates

Your insurer will compare:

• Your statement vs the other driver’s
• Damage patterns vs the reported story
• Any independent evidence (dashcam, witnesses, police refs)

If liability is disputed, being able to provide follow-up details quickly can help the claim move more smoothly.

Making Sure You’re Able to Claim and Recover the Costs

This is the admin that can save stress later:

• Keep every receipt (taxis, prescriptions, parking, etc.)
• Keep photos and documents together in one folder
• Chase updates politely but regularly
• If something feels wrong (like liability being recorded incorrectly), challenge it early

If you are unsure what to do next after a non-fault accident, calling promptly can help you understand what details matter, what information to gather and what may happen next. The options available can depend on liability, cover, vehicle condition and the evidence available.

FAQs

Do I have to tell my insurer even if I am not claiming?
Often yes, because many policies require you to report incidents. Check your wording.

Will my premium always go up after a non-fault claim?
Not always, but it is common for it to rise, and different insurers price it differently. (Compare the Market)

Does no-claims protection stop my premium rising?
Usually it protects the discount, not the underlying price. (MoneySavingExpert.com)

How long do I need to declare a non-fault accident for?
Insurers vary, but many ask for incidents or claims over several years, so always answer the quote questions exactly as asked.

What if it was a hit-and-run or uninsured driver?
The MIB provides routes for compensation, with different rules depending on whether the driver is uninsured or untraced. (mib.org.uk)

If you are dealing with a non-fault accident, calm evidence-gathering, tidy paperwork and prompt reporting can make the process easier to follow.
