What Is A Non-Fault Accident?

A non-fault accident is when you’re involved in a crash or incident, but you’re not held legally responsible for what happened, so the other driver (or another party) is liable for the damage and losses.

Even so, it can still affect your insurance in ways that surprise people, so it’s worth understanding how insurers decide “fault”, what happens to your premium, and how your no-claims discount (NCD) is treated.

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 your insurer (or the other side’s insurer) accepts that another party is responsible.

The key point is this: insurers don’t label a claim “non-fault” just because you feel blameless.
They normally treat it as non-fault when liability is accepted and (often) when costs are recovered from the other side.

Here’s 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 can pursue their insurer to recover costs (repairs, hire car, outlays).

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 decide fault based on 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, many rear-end shunts).
Other times it’s messy, and you might see split liability (like 50/50) if both sides share some blame.

When Your Insurer Investigates Whose Fault It Was

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

If liability is disputed, it can take longer, and some outcomes (like your excess refund or your NCD 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 bit people hate: 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’ve been involved in any incident, because their pricing models use claims history as a predictor. Price comparison guidance is pretty blunt on this point. (Compare the Market)

So, yes, it can feel unfair.
But it’s common.

Impact on Your No Claims Discount and NCD Protection

In many cases, if you’re not at fault and the insurer recovers the money, your NCD isn’t reduced. (Admiral)

If you’ve paid for NCD protection, that usually protects the discount level, but it doesn’t guarantee your total premium won’t rise. (MoneySavingExpert.com)

So NCD protection can help, but it’s not a magic shield.

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’s why two people can have the same “non-fault” outcome, but see very different renewal jumps.

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

The Car Insurance Claim Process for Non-Fault Accidents

Typically:

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 wrap up quickly.
Others drag on, especially if liability is disputed.

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 turn into 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’s written off, the insurer normally settles based on market value just before the crash.
If you disagree, you can raise evidence like 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 via insurers and repair networks.

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’re injured, getting checked medically is important for you and for the paper trail.

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

If the other driver is uninsured, your insurer may still help (especially if you’re comprehensive), but recovery is harder.

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:

• 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 vary.

Will Another Claim in the Future Impact My NCD?

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

Also, most insurers ask about incidents/claims over a set period (often 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 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

Then:

• 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 it’s disputed, be ready to provide follow-up details quickly.

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

This is the “boring admin” that saves money 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

FAQs

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

Will my premium definitely go up after a non-fault claim?
Not always, but it’s 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/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’re dealing with a non-fault accident, a bit of evidence-gathering and tidy paperwork can make the whole thing far less painful.
