How to Avoid Common Mistakes When Buying Car Insurance

As an FCA-authorised expert broker that has arranged over 800,000 policies, WeCovr understands the UK motor insurance market inside out. Navigating the world of car, van, and fleet insurance can feel like a minefield, but avoiding a few common mistakes can save you hundreds, and sometimes thousands, of pounds.

WeCovr reveals the top pitfalls UK drivers make when arranging cover — and how to avoid them

Arranging the right motor policy is more than just a box-ticking exercise; it’s about securing financial protection for one of your most valuable assets. Yet, every year, countless UK drivers, business owners, and fleet managers make easily avoidable errors that lead to overpaying for their premiums or, worse, discovering their cover is invalid when they need it most.

This expert guide will walk you through the most common mistakes and provide actionable advice to ensure you get the right protection at the best possible price.

Understanding Your Legal Obligations: The Foundation of Motor Insurance UK

Before diving into the common pitfalls, it's crucial to understand the legal framework. In the United Kingdom, the Road Traffic Act 1988 mandates that any vehicle used or kept on a public road must have at least third-party motor insurance. Driving without valid insurance is a serious offence that can lead to unlimited fines, penalty points, and even disqualification from driving.

There are three primary levels of cover available to private and business drivers:

1. Third-Party Only (TPO): This is the minimum level of cover required by law. It covers injury or damage you cause to other people, their vehicles, or their property. It does not cover any damage to your own vehicle or your own injuries.
2. Third-Party, Fire and Theft (TPFT): This includes everything TPO covers, plus protection for your own vehicle if it is stolen or damaged by fire.
3. Comprehensive: This is the highest level of cover. It includes all the protection of TPFT, and it also covers damage to your own vehicle in an accident, even if you were at fault.

Comparing Levels of Car Insurance Cover

For businesses, the obligations are similar. A sole trader using a van for work needs at least commercial TPO. A company with multiple vehicles should consider fleet insurance, a single policy that covers all vehicles, simplifying administration and often reducing overall costs.

Mistake #1: Automatically Renewing Without Comparing Quotes

The single biggest mistake UK drivers make is letting their policy automatically renew without first checking the market. For years, insurers relied on customer inertia, often charging loyal customers more than new ones—a practice known as "price walking."

While the Financial Conduct Authority (FCA) introduced rules in 2022 to tackle this by ensuring renewal quotes are not more expensive than an equivalent new business quote from that same insurer, it does not guarantee your renewal price is the most competitive on the wider market.

According to the Association of British Insurers (ABI), the average price paid for comprehensive motor insurance in the first quarter of 2024 was £635, a record high. With costs rising, shopping around is more critical than ever.

How to avoid this:

• Never accept your renewal quote blindly. Use it as a benchmark.
• Start shopping around 3-4 weeks before your renewal date. Insurers know that last-minute buyers are often more desperate and may quote higher prices.
• Use an independent broker like WeCovr. We compare policies from a wide panel of UK insurers, including specialist providers, to find the right cover for your specific needs, whether for a private car, a commercial van, or an entire fleet. This service costs you nothing and saves you both time and money.

Mistake #2: Choosing the Wrong Level of Cover or Use

Selecting the right policy goes beyond just picking a brand. It's about matching the cover to your real-world usage.

The False Economy of Third-Party Only Cover

It seems logical that less cover should mean a lower price. However, in the world of motor insurance, this is often not the case. Insurers analyse vast amounts of data, and their statistics show that drivers who opt for Third-Party Only cover tend to be in higher-risk groups and are more likely to make a claim.

As a result, it is common to find that a Comprehensive policy is cheaper than a TPO or TPFT quote from the same provider.

Real-life Example: A young driver in a city centre might seek a TPO policy to save money. However, insurers may quote £1,500 for TPO but only £1,300 for a Comprehensive policy, viewing the driver selecting the higher cover level as more responsible.

How to avoid this:

• Always get quotes for all three levels of cover. You might be surprised to find that Comprehensive offers more protection for less money.

Underinsuring for Business Use

This is a critical pitfall, especially for sole traders, freelancers, and small business owners. Standard policies are broken down into different classes of use:

• Social, Domestic & Pleasure (SD&P): Covers trips for shopping, visiting family, and holidays. It does not cover travel to and from work.
• Commuting: Covers SD&P plus travel to and from a single, permanent place of work.
• Business Use (Class 1, 2, or 3): This is required if you use your car for any work-related purposes beyond commuting. This includes:
  • A care worker visiting multiple patients.
  • A salesperson travelling to meet clients.
  • An engineer driving to different sites.
  • Even driving to the post office to send a business parcel.

Using your vehicle for business without the correct class of use will invalidate your insurance. If you have an accident, your insurer can refuse to pay out the claim, leaving you personally liable for all costs.

How to avoid this:

• Be honest and precise about how you use your vehicle. If your work involves more than just commuting to one office, you need business car insurance.
• Consult an expert. A broker like WeCovr can ensure your policy accurately reflects your needs, whether you're a private individual or require a commercial vehicle or fleet insurance policy.

Mistake #3: Setting an Incorrect Voluntary Excess

Your policy excess is the amount you agree to pay towards any claim you make. It's made up of two parts:

1. Compulsory Excess: A fixed amount set by the insurer. This is non-negotiable and often higher for young or inexperienced drivers.
2. Voluntary Excess: An amount you choose to add on top of the compulsory excess.

Typically, a higher voluntary excess will result in a lower premium. However, setting it too high can be a costly mistake.

The Excess vs. Premium Trade-Off

In the example above, increasing the voluntary excess from £100 to £500 saves £150 on the annual premium. However, if you make a claim, you'll have to find £750 out of your own pocket. If a minor repair costs £800, you would pay £750 and the insurer only £50.

How to avoid this:

• Set a voluntary excess that you can genuinely afford to pay at a moment's notice. Don't be tempted by a lower premium if the excess is beyond your means.
• Calculate your break-even point. Consider how many years you would need to go without a claim to make the premium saving worthwhile.

Mistake #4: Not Understanding or Protecting Your No-Claims Bonus (NCB)

Your No-Claims Bonus (NCB), or No-Claims Discount (NCD), is one of the most valuable assets in motor insurance. For every year you drive without making a claim, you earn a discount on your premium for the following year. This can be substantial, often reaching 60-70% or more after five or more consecutive claim-free years.

Typical NCB Discount Progression

Note: Discounts vary significantly between insurers.

Making a single "at-fault" claim can drastically reduce or even wipe out your NCB. Insurers use a "step-back" system, where a claim reduces your bonus by a set number of years. For example, a driver with 5 years of NCB might "step back" to 3 years after one claim.

Protected No-Claims Bonus

For an additional fee, many insurers offer "NCB Protection." This allows you to make one, or sometimes two, at-fault claims within a set period (e.g., three years) without your discount level being affected.

Is it worth it?

• Consider the cost: Protection adds to your premium.
• Consider your discount: The higher your NCB, the more you have to lose, making protection more valuable.
• Read the small print: Protection doesn't prevent your overall premium from rising after a claim due to other factors, but it does preserve the percentage discount.

Mistake #5: Inaccurate or Dishonest Declarations

When you apply for insurance, you are entering into a contract based on "utmost good faith." This means you have a legal duty to provide information that is accurate to the best of your knowledge. Any misrepresentation, whether intentional or accidental, can lead to your policy being voided.

Key areas where mistakes happen:

• The Main Driver and "Fronting": This is a common form of insurance fraud where a more experienced person (e.g., a parent) is named as the main driver of a car that is primarily used by a higher-risk driver (e.g., their student son or daughter). While it may seem like a harmless way to get a cheaper quote, the consequences are severe:

  • The policy will be cancelled immediately.
  • The claim will be rejected.
  • The young driver may be prosecuted for driving without insurance.
  • Both parties may get a record with the Insurance Fraud Bureau, making it extremely difficult and expensive to get insurance in the future.

• Address and Overnight Location: Your postcode and where the car is kept (e.g., garage, driveway, public road) are major rating factors. You must provide the address where the car is normally kept overnight, not a parent's rural address if you live and park in a city centre.

• Occupation: Be precise. "Journalist" might carry a different risk profile to "Editor." "Builder" might be different to "Construction Site Manager." Use your insurer's dropdown list to find the most accurate description.

• Annual Mileage: Underestimating your mileage to save money is a false economy. If you have an accident after having driven 12,000 miles when you declared only 8,000, your insurer could reduce the claim payout or even void the policy. Check your MOT history on the gov.uk website to see your past annual mileage.

• Vehicle Modifications: You must declare all modifications from the factory standard. This includes:

  • Alloy wheels
  • Spoilers and body kits
  • Engine remapping or chipping
  • Exhaust system changes
  • Even tow bars or roof racks on some policies.

  Failure to declare modifications can invalidate your cover.

Mistake #6: Overlooking or Overpaying for Optional Extras

Insurers offer a menu of add-ons to enhance a standard policy. While some are valuable, others may be unnecessary or already covered elsewhere.

Common Motor Insurance Add-Ons

How to avoid this:

• Audit your needs. Don't tick every box. Decide which protections are genuinely important to you.
• Check for duplicate cover. Review your bank account benefits and home insurance policy before paying for extras.
• Let WeCovr help. Our experts can talk you through the options, explaining the real-world benefits of each add-on so you can make an informed decision. We also offer discounts on other insurance products if you purchase motor cover through us.

Mistake #7: Ignoring the Impact of Your Vehicle Choice

The car you drive is one of the biggest factors determining your premium. All UK cars are assigned an insurance group rating from 1 (the cheapest to insure) to 50 (the most expensive). This rating is set by the Group Rating Panel, administered by Thatcham Research.

Factors that influence a car's group rating include:

• New Car Value: The price of the car when new.
• Repair Costs: The cost of parts and the time it takes to repair common accident damage.
• Performance: High-performance cars with rapid acceleration and top speeds are in higher groups.
• Security: Factory-fitted alarms, immobilisers, and tracking devices can lower the group rating.

Electric Vehicles (EVs): While EVs are becoming more common, they often sit in higher insurance groups. This is due to the specialist skills and equipment needed for repairs, particularly for the battery pack, which can cost thousands to replace. However, some insurers are now offering "green" discounts for EV owners.

How to avoid this:

• Research before you buy. Before committing to a car, get an insurance quote. A sporty trim level or a more powerful engine can push the same model up several insurance groups, costing you hundreds more each year.

Frequently Asked Questions (FAQ)

1. What is the difference between an 'at-fault' and a 'non-fault' claim? An 'at-fault' claim is one where your insurer has to pay for the damages and cannot recover the costs from a third party. This includes accidents where you were to blame, but also situations where fault cannot be proven (e.g., a car park prang with no witness) or the other driver was uninsured. A 'non-fault' claim is where your insurer pays for your repairs but successfully recovers the full cost from the person responsible for the accident. Generally, only at-fault claims affect your No-Claims Bonus.

2. Will a speed awareness course affect my insurance premium? Most insurers do not ask if you have attended a speed awareness course and will not increase your premium as a result. You do not need to declare it unless specifically asked. However, if you chose to take the penalty points and fine instead, you must declare these convictions, and they will almost certainly increase your premium.

3. Is it cheaper to pay for car insurance annually or monthly? It is almost always cheaper to pay for your motor policy annually. When you pay monthly, you are effectively taking out a high-interest loan from the insurer or a third-party finance company to cover the full year's premium. This can add 10-30% to the overall cost. If you can afford to pay in one lump sum, you will save a significant amount of money.

4. Can I insure a car that I don't own? To insure a car, you must have an "insurable interest" in it. This means you would suffer a financial loss if it were damaged or stolen. While you don't have to be the registered keeper (the person named on the V5C logbook) to insure a vehicle, you typically need to be its main driver and have the owner's permission. This is common for people on long-term leases or those driving a family member's car.
