Can you return a used car to a dealer in the UK?

A car is a big investment, so discovering that the vehicle you've bought from a dealership is faulty can be incredibly frustrating. Maybe the engine warning light came on three days after collection, or the gearbox started slipping on the drive home. The question is, can a used car be returned in the UK?

The short answer is yes, but the route you take depends on the fault, how you bought the car, and how long you've owned it.

In this guide, you'll learn exactly when you can reject a used car, whether you can get a refund, and how the rules change in different situations – with insights from Dylan McCabe, owner of North Loop Autohaus, on what the process looks like from the dealer's side.

Your rights when returning a used car from a dealer

Under consumer law, a car is treated as a "good" like any other physical item you might end up wanting to return. It’s clearly set out in the Consumer Rights Act 2015, which is a key piece of legislation protecting consumers in the UK.

When you buy a new or used car from a UK dealership, the Consumer Rights Act 2015 states it must be:

• Of satisfactory quality, meaning the car "meets the standard that a reasonable person would consider satisfactory," taking into account factors like its age, price and description. It shouldn't have faults or defects unless they were clearly disclosed before the sale.
• Fit for a particular purpose, meaning the car must be suitable for any specific purpose you made known to the dealer. For example, if you said you needed a car for long-distance commuting, the vehicle should be able to handle that.
• As described, meaning the car must match the dealer's description. Any change to that information, whether made before or after the contract is signed, is only valid if both the buyer and the seller agree.

In terms of a used car return policy, UK dealers can be asked to put things right if the car falls short on any of these points.

How long do you have to return a car?

The Consumer Rights Act 2015 sets out three different time intervals within which you can return a faulty car to a dealer and expect the claim to be accepted. It’s easy to waste crucial time asking yourself, ‘Can I really return a car I just bought?’, but the clock usually starts the day after the car is delivered to you, so it pays to act quickly.

Within 30 days: short-term right to reject

If you discover an issue and are thinking of returning a car within 30 days of purchasing it, you have “the short-term right to reject” it. This allows you to return a vehicle and get a full refund.

Another option is to have it repaired or replaced, but this doesn’t mean the dealership can refuse a refund if you request one.

Between 30 days and 6 months

After 30 days, the dealer is permitted one attempt to fix the car if an issue arises and you have owned the car for less than 6 months. Within this timeframe, the dealership is still expected to acknowledge that the problem existed at the time of purchase.

If you request a repair or replacement, you must allow the dealer a reasonable amount of time to resolve the issue unless it causes you significant inconvenience. However, you can’t ask for repair or replacement if:

• It’s impossible (e.g., parts are no longer available or the car can't be repaired).
• One option is much more reasonable than the other based on cost or effort (e.g., it may be quicker or cheaper to repair the car than to replace it).
• The car's value after repair may still not conform to the contract (e.g., it’s still not up to the standard you expected or was promised).

If that single repair or replacement fails, you can reject the car for a refund or keep it and claim a price reduction. Keep in mind that if you reject the car at this stage, the dealer could end up deducting a reasonable amount for the use and mileage you have had since you bought it.

After 6 months

Unlike during the first 6 months, when it’s assumed that the fault existed from the start, after 6 months, it becomes your responsibility to prove that the issue existed at the time of purchase. You will need evidence that the problem is not related to normal wear and tear to get it fixed or ask for a partial refund.

According to Dylan McCabe, owner of North Loop Autohaus, one of the best ways to support your claim is a clear timeline showing when the vehicle was purchased, its mileage at the time, when the issue first appeared, the mileage when the fault was discovered, and what exactly happened.

Buyers should keep copies of the vehicle advert, invoice, service history, MOT records, warranty documents, finance paperwork, and any emails or messages exchanged with the dealer. Photos, videos, warning lights, diagnostic fault codes, recovery reports, and written garage reports may also help demonstrate the nature and timing of the fault.

"From a dealer's point of view, the easier it is to understand the issue and the timeline, the easier it is to deal with it fairly," says McCabe.

McCabe also notes that buyers may need to pay for diagnostic work themselves if they cannot return the vehicle to the supplying dealer for inspection. However, if it later becomes clear that the fault falls under the dealer's responsibility, the dealer may agree to reimburse those costs.

Even after six months, if you can prove the fault, the dealer is still allowed to attempt a repair before issuing any refund. A successful claim can lead to a repair, a partial refund, or a price reduction, depending on the circumstances.

When can a dealer refuse to accept a return?

Dealers must take legitimate complaints seriously and follow the law under the Consumer Rights Act 2015. If the buyer’s complaint is valid – meaning that the car isn’t of satisfactory quality, doesn’t fit for purpose, or isn’t as described – the dealer is legally obligated to offer the solution, such as repair, replacement, or refund.

On the other hand, not every fault automatically entitles a buyer to reject a vehicle. According to McCabe, when it comes to used cars, factors such as its age, mileage, condition, price, and the nature of the fault all influence how a complaint is assessed.

“The best outcomes usually occur when both sides stick to the facts and allow the issue to be properly investigated,” says McCabe.

"The first thing I'd always say is don't panic, and don't rush into getting the car repaired elsewhere straight away. Instead, contact the selling dealer as soon as possible and explain the issue clearly. Once parts have been replaced or repairs completed, it can become much harder to determine what caused the fault and whether it was present when the car was sold.”

A dealer is generally within their rights to refuse a return when:

• You've simply changed your mind. Buyer's remorse isn't covered if you bought the car in person.
• The fault is reported well outside the statutory windows. That means after 30 days for a full refund, or after 6 months for the presumption of the fault being present at sale.
• The fault was disclosed before the sale. For example, if it was listed on the invoice, in the advert or in writing.
• The problem is fair wear and tear. Issues in line with the car's age, price and mileage are not the same as a car bought from a dealer being faulty.
• The damage was caused by you. This includes misuse, accident damage or missed servicing. In these cases where the buyer wasn’t sold a faulty car, the dealer is not obligated to take action.
• You haven't given the dealer their one repair attempt. After the first 30 days, the law entitles the dealer to one attempt at a repair or replacement before you can reject.

If the fault appears within the first 6 months, the law assumes it was already there at the time it was sold, unless the dealer can prove otherwise. If the dealer makes a flat refusal at this point, without evidence, it is unlikely to stand up.

Refunds and deposits when returning a car

When you return a car, two financial questions usually come to mind: how much money actually gets refunded, and what happens to the deposit you've already paid? The rules are different for each.

How is the refund calculated?

There's no single legal formula for working out a refund. Within the first 30 days, you're entitled to a full refund with no deduction for usage. After 30 days, the dealer can deduct a "reasonable amount" for the use you've had of the car, and most calculate this on a pence-per-mile basis, commonly between 20p and 40p per mile.

If the dealer's deduction looks harsh, make sure to ask them for a written breakdown. Starting points above 40p per mile are often challenged successfully through the Financial Ombudsman Service.

Can you get your deposit back?

Car deposit refund law in the UK varies depending on how you paid. If you handed the deposit over at the dealership in person, it's generally legally binding and not refundable just because you've changed your mind. The main exceptions are if the dealer can't supply the car, your finance application is declined, or the dealer breaches the contract.

If you placed the deposit entirely online or by phone, the 14-day cooling-off period under the Consumer Contracts Regulations 2013 applies, and the deposit must be refunded if you cancel. Always read the contract before you pay, as while some car deposit refunds are clearly stated as possible, others are non-refundable.

Can you return a car bought online?

Buying a car online has become normal, and the rules are a lot more generous than many people expect. If you bought it entirely at a distance, you can return a car after purchase even if there is nothing wrong with it.

The 14-day cooling-off period

It’s common to wonder, can I return a used car within 14 days? The 14-day window starts the day after the car is delivered, and you don't need to give a reason for cancelling. Fair use rules still apply, so extensive mileage or any damage could lead to a deduction (some dealers cap usage at 30 miles for a full refund).

You must notify the dealer in writing within the 14 days, then you have a further 14 days to return the car, with the return costs usually falling on you, the buyer. One important exception, though, is if you visited the dealership in person before completing the purchase online, as the distance selling rights may not apply in that case.

Can you return a new car?

The same Consumer Rights Act 2015 protections apply to new cars: they must be of satisfactory quality, fit for purpose and be as described.

If a new car develops a fault within 30 days of delivery, you still have the short-term right to reject it for a full refund. If you buy a new car entirely online or by phone, the 14-day cooling-off period under the Consumer Contracts Regulations 2013 also applies.

However, there's no automatic right to return a new car simply because you've changed your mind after buying in person.

Can you return a car bought on finance?

Returning a car bought on finance depends on why you're returning it and how far through the agreement you are. You may be protected by the Consumer Credit Act 1974, by your card provider's chargeback scheme, or by the voluntary termination clause built into your own finance agreement.

Section 75: returning a car paid by credit card

Under Section 75 of the Consumer Credit Act 1974, the lender is jointly and severally liable for any breach of contract or misrepresentation by the seller if you bought a faulty car on finance. This allows you to pursue a claim not only against the car dealer but also against the finance company.

There are some key conditions to qualify for Section 75 car purchase protection:

• There must be a breach of the agreement (for example, the car is faulty or not fit for purpose) or false information given (for example, you were misled about the car's condition).
• The car must have cost over £100 and not more than £30,000.
• Your credit card provider and the car seller must be different parties. Section 75 won't apply if the lender is also the seller.

You can't just make a claim without providing evidence that the car had previously undisclosed issues and that those aren't your fault. Check the vehicle's description against what you bought, and be ready to prove that the current state of the car doesn't match how it was presented at the time of purchase.

There's no need to contact the seller or the finance company first; you can claim against both at the same time. The time frames and options for rejecting or repairing the car are the same as those under the Consumer Rights Act 2015. You can also claim under Section 75 even if only part of the payment, such as the deposit, was made by credit card.

Debit card chargeback

If you paid by debit card, you don't get Section 75 protection, but you can ask your bank for a chargeback. While chargeback isn't a legal right, it is a voluntary scheme run by the card networks where the bank tries to reverse the transaction. It only works if the dealer still holds the funds, so it's worth raising as soon as possible by contacting your bank directly.

Voluntary termination: the halves rule

Voluntary termination lets you hand a car back on a hire purchase (HP) or personal contract purchase (PCP) agreement, and it is based on how much you have paid rather than on any fault.

You can use it once you have paid at least 50% of the total amount payable, including interest and fees. If you are not quite there, you can pay the difference to reach the halfway point and still walk away. The car must be returned in reasonable condition, and the option does not apply to ordinary lease (PCH) agreements.

Expert tips for successfully returning a faulty car

Understanding your rights when returning a faulty car is important, but there are also extra steps you can take to help get a positive result for your claim:

• Don't continue driving the car. Carrying on after noticing a fault can weaken your claim and increase any deduction for use.
• The sooner you report the issue, the better. If you notice something wrong, don't delay contacting the dealer; your options narrow over time.
• Avoid making your own repairs. Arranging repairs before the dealer has had an opportunity to inspect the vehicle can make it much harder to determine the cause of the fault and who is responsible for it.
• Show the car to a professional. Have a qualified mechanic inspect the car and provide a written report explaining the nature of the fault and its likely cause.
• Document everything. Save all communications with the seller or finance company, including emails, messages and invoices. Avoid verbal agreements and put everything in writing.
• Be specific. Include details of when the fault occurred, its nature, and any supporting evidence such as the mechanic's report.
• Communicate professionally. While it's important to understand your legal rights, approaching the dealer calmly and allowing them to investigate the issue often leads to a faster resolution.
• Consider getting legal advice. Consult a legal advisor if negotiations stall or you feel the dealer isn't acting in good faith. They can help you draft formal letters and explain more fully what to do if a dealership sells you a faulty car.

How to reduce the risk of buying a problematic used car

Although consumer rights can help protect you after a purchase, preventing problems in the first place is always the better option. Before buying a used car, there are several checks you can carry out to spot potential red flags and make a more informed decision.

Get a carVertical report

If you've already purchased the car and identified a fault, a vehicle history report can be valuable in proving that the car had undisclosed issues at the time of sale, such as previous accidents. It isn't a legal document, but it's strong supporting evidence.

An even better option is to get a carVertical report before signing the contract, so that you can make a more informed decision and avoid all the hassle altogether.

Many dealerships that partner with carVertical empower their buyers by offering car history reports free of charge, increasing transparency and trust. You can always ask whether this is an option.

A carVertical report typically includes essential information about a car's past, such as damage records, odometer readings (and mileage rollbacks, if any), ownership changes, historical photos, outstanding finance, and more.

By obtaining a vehicle history report, you can identify potential red flags and understand whether a car's condition meets your expectations before finalising your purchase. This approach not only helps you avoid future issues with the vehicle but also boosts your confidence in the buying process.

Review the service history carefully

However, a vehicle history report is only one part of the picture. According to Dylan McCabe, service history is one of the strongest indicators of a used car's future reliability.

“Before buying, ask the dealer for the details: service dates, mileage readings, and the work that has been carried out. Some more complex cars, such as performance cars or SUVs, require more than routine oil changes – they may also need cam belt replacements, gearbox servicing, differential servicing, and other maintenance," says McCabe.

"These services aren't necessarily super expensive, but neglecting them can lead to repairs costing thousands of pounds. In my experience, many owners and dealers are either unaware of the correct service schedule or choose to ignore it due to cost."

Book a professional inspection

A vehicle history report and service records can tell you a lot about a car's past, but they won't always reveal its current condition. For added peace of mind, consider having the vehicle inspected by an independent mechanic before purchase.

A pre-purchase inspection can help identify issues that may not be obvious during a test drive, such as excessive wear, poor-quality repairs, or fluid leaks. The cost of an inspection is often small compared with the potential cost of unexpected repairs, especially when buying a high-value, high-mileage, or specialist vehicle.
