UK Drivers: The 5 Critical Mistakes You Make After a Car Accident That Could Cost You Thousands in Claims & Future Premiums

The screech of tyres, the sickening crunch of metal—a car accident is a traumatic and disorienting experience. In the UK, with millions of vehicles on our roads, incidents are unfortunately common. What you do in the minutes and hours that follow is critical. At WeCovr, an FCA-authorised motor insurance brokerage that has helped arrange over 800,000 policies, we know that a few simple mistakes can jeopardise your claim, invalidate your policy, and dramatically increase your future premiums.

This guide will walk you through the five most common and costly errors drivers make after a collision. Understanding these pitfalls will empower you to protect yourself, your finances, and your driving future.

First, A Quick Refresher: Your Legal Motor Insurance Obligations

Before we explore the mistakes, it's vital to understand the foundation of UK motor insurance. It is a legal requirement under the Road Traffic Act 1988 to have at least third-party insurance for any vehicle used on public roads. Driving without it can lead to unlimited fines, penalty points, and even a driving ban.

There are three main levels of cover:

For businesses, fleet insurance or business car insurance is essential. This covers vehicles used for work purposes and ensures the company meets its legal duty of care to employees and the public. Failing to have the correct business use on a policy can invalidate it entirely in the event of a claim.

Now, let's look at the mistakes that can undo all the good of having the right policy.

Mistake #1: Failing to Stop or Exchange Details at the Scene

This is the most serious error you can make, with significant legal consequences. The shock and panic of an accident can make you want to drive away, but you must resist this urge.

Your Legal Duty

Under Section 170 of the Road Traffic Act 1988, if you are the driver in an accident that causes injury to a person or animal, or damage to another vehicle or property, you must stop.

After stopping, you are legally required to provide your name, address, and vehicle registration number to anyone with reasonable grounds to ask for them. This includes the other driver, property owners, or the police. If you don't exchange details at the scene (for instance, if you hit a parked car and the owner isn't present), you must report the accident to the police as soon as is reasonably practicable, and in any case within 24 hours.

What Happens If You Don't Stop?

Failing to stop or report an accident is a criminal offence. The penalties can be severe:

• Up to £5,000 fine
• 5 to 10 penalty points on your licence
• A potential driving disqualification
• In the most serious cases, up to six months in prison

Real-Life Example: A driver in a supermarket car park lightly scraped another vehicle's bumper. Panicking, they drove off. A witness noted their registration, and the police traced them. The driver received 6 penalty points and a £400 fine for "failing to stop and report an accident"—a far harsher penalty than the minor cost of the bumper repair would have been.

What to do instead:

1. Stop: Immediately and safely. Turn on your hazard lights. Switch off your engine.
2. Check for Injuries: Assess yourself, your passengers, and the occupants of other vehicles for any injuries. If anyone is hurt, call 999 immediately.
3. Exchange Details: Calmly provide your name, address, phone number, and insurance details (insurer's name and policy number). Get the same from the other party. Do not rely on a verbal exchange; take a photo of their details or write them down.
4. Report to Police: You must report the accident to the police within 24 hours if anyone is injured or if you were unable to exchange details at the scene.

Mistake #2: Admitting Liability (Saying "Sorry" or "It Was My Fault")

In the heat of the moment, it's a natural human reaction to apologise, especially if someone appears shaken or upset. However, when it comes to a car accident, apologising can be interpreted as an admission of liability.

Why This Is a Problem

Your motor insurance policy is a contract. A key condition of this contract is that you must not admit fault, liability, or make any offer of payment. It is your insurer's job—and their legal right—to investigate the incident and determine who is legally responsible (liable).

If you admit fault at the scene, you bypass this process. The other party's insurer can use your statement against you, forcing your insurer to pay out, even if evidence later suggests you weren't to blame. In a worst-case scenario, your insurer could argue that you breached your policy terms and refuse to cover the claim, leaving you personally liable for thousands of pounds in damages and legal fees.

What to Say Instead of "Sorry"

You can be humane without admitting fault. Focus on the well-being of everyone involved.

Remaining calm and sticking to the facts is your best defence. Let the evidence and the insurance experts do the talking.

Mistake #3: Not Gathering Enough Evidence

After ensuring everyone is safe, your next priority is to become a detective. The evidence you collect in the 15 minutes after an accident can be the difference between a successful claim and a "he said, she said" dispute that goes against you.

Your insurer wasn't there. They rely entirely on the information you provide to build a case. Without solid evidence, it becomes difficult for them to defend you or pursue a recovery from the other party.

Your Essential Post-Accident Evidence Checklist

Remember, you can never have too much evidence. Use your smartphone to take dozens of photos and even a video walking around the scene.

Mistake #4: Delaying or Failing to Report the Accident

This is a common and dangerous misconception. Many drivers believe that if the damage is minor or if they agree to settle it privately "outside of insurance," they don't need to tell their insurer. This is incorrect and breaches your policy terms.

The "Duty to Disclose"

Your insurance policy is a contract of "utmost good faith." This means you have a duty to inform your insurer of any material facts that could affect their assessment of your risk. An accident, no matter how small, is a material fact.

Most policies state that you must report any accident, theft, or loss as soon as reasonably possible, which is typically within 24-48 hours. This is true even if you don't plan to make a claim on your own vehicle cover.

Why You Must Always Report It

1. The Other Driver Might Change Their Mind: You might agree to a private settlement of £200 for a bumper scuff. A week later, the other driver could claim they have whiplash and submit a personal injury claim to your insurer for thousands. If you haven't reported the incident, your insurer may be entitled to reject the claim, leaving you to foot the bill.
2. Hidden Damage: What looks like a minor dent could be hiding significant structural damage underneath. The cost could be far greater than you initially thought. Modern cars with advanced driver-assistance systems (ADAS) have sensors in bumpers that can cost thousands to recalibrate after even a minor knock.
3. Policy Invalidation: If your insurer discovers you failed to report an incident (for example, at renewal time when they check claims databases), they could cancel your policy. A cancelled policy makes it extremely difficult and expensive to get motor insurance UK in the future.

WeCovr Pro Tip: Even if you have no intention of claiming, you should still report the incident to your insurer "for information only." This fulfils your contractual duty and protects you if the other party decides to claim later. A good broker like WeCovr can guide you on the best way to do this without immediately impacting your policy.

Mistake #5: Accepting the First Settlement Offer or Using Unauthorised Repairers

If the accident wasn't your fault, you will likely be contacted by the other driver's insurance company. They may act quickly, offering you a cash settlement or directing you to one of their repairers. Be very cautious.

The Third-Party Insurer's Goal

The other insurer's primary goal is to close the claim for the lowest possible cost. Their first offer for your vehicle's value or for any injury may be significantly less than what you are entitled to. They are working for their own customer and shareholders, not for you.

The Danger of Unauthorised Repairers

The other insurer might also push you to use their "recommended" repairer. While convenient, this can have downsides:

• They may use non-genuine parts (often called "pattern parts") to save costs.
• The quality of the repair may not be guaranteed to the same standard as your own insurer's network.
• Using them could potentially void your vehicle's warranty, especially on newer cars.

What to do instead:

1. Speak to Your Insurer First: Always let your own insurance company handle the claim. They work for you. A comprehensive policy is designed to get you back on the road with minimum fuss. Your insurer's job is to restore you to the financial position you were in before the accident.
2. Use Approved Repairers: Your insurer will have a network of approved garages. Using them ensures that genuine parts are used where possible, and the work is typically guaranteed for several years.
3. Consider Legal Expenses Cover: This optional extra (often called Motor Legal Protection) is invaluable. It provides up to £100,000 in legal fees to help you recover uninsured losses, such as your policy excess, loss of earnings, or compensation for injury, if the accident wasn't your fault.

How a Claim Affects Your Finances: NCB, Excess, and Premiums

Making a claim, even a non-fault one, can have a financial ripple effect. Understanding these concepts is key to managing your costs.

Your No-Claims Bonus (NCB)

Your NCB (or No-Claims Discount) is a significant discount applied to your premium for each consecutive year you go without making a claim. It can be worth up to 70% or more off your policy cost.

A single fault claim typically reduces your NCB dramatically, as shown in the example below.

NCB Protection: For a small additional cost, you can protect your NCB. This allows you to make one or two fault claims within a set period (usually 3-5 years) without your discount level being reduced. Note: it protects the discount, not the underlying premium, which will still likely rise after a fault claim.

Your Policy Excess

The excess is the amount you must contribute towards any claim for damage to your own vehicle. It's made up of two parts:

• Compulsory Excess: A fixed amount set by the insurer, often based on your age, vehicle, and driving history.
• Voluntary Excess: An amount you agree to pay on top of the compulsory excess. A higher voluntary excess usually results in a lower premium.

You pay the total excess (compulsory + voluntary) when you make a fault claim. If the claim is deemed non-fault and your insurer successfully recovers all costs from the at-fault party's insurer, your excess will be refunded to you.

The Impact on Your Future Premium

This is the big one. According to the Association of British Insurers (ABI), a driver with a fault claim can expect their premium to increase by 20-50% at the next renewal. This is because you are now considered a higher risk.

Even a non-fault claim can sometimes lead to a small premium increase. Insurers' data suggests that drivers involved in any accident (even if hit while parked) are statistically more likely to be involved in another one.

This is where an expert broker like WeCovr provides immense value. After a claim, your existing insurer may no longer be the best car insurance provider for your new circumstances. WeCovr can compare quotes from a wide panel of specialist insurers to find you an affordable motor policy, even with a claim on your record. We also help our clients secure discounts on other policies, such as home or life insurance, when they buy motor cover through us.

Specialist Vehicles and Fleet Management

The principles remain the same for motorcycles, vans, and HGVs, but the stakes are higher. Damage can be more extensive, and for businesses, vehicle downtime means lost revenue.

For fleet managers, having a robust post-accident procedure is non-negotiable. Drivers must be trained on:

• What to do at the scene.
• Who to call immediately (a dedicated fleet manager or claims line).
• How to use the vehicle's telematics or dashcam system to secure evidence.
• Completing an incident report form accurately and promptly.

WeCovr specialises in creating tailored fleet insurance policies that include risk management support and efficient claims handling to get your vehicles back on the road quickly. A well-managed claim process minimises disruption and controls the impact on future premiums.
