Quick answer
Realising the car you've just bought has been wound back is a horrible moment, but it's also a well-trodden path, with established rights and realistic routes to your money. What matters now is sequence: confirm, evidence, claim, report, in that order and in writing.
This guide walks through each step, including the differences between dealer and private purchases and what the card and finance routes add. It's general information rather than legal advice. For the specifics of your case, the Citizens Advice consumer service on 0808 223 1133 will tell you exactly where you stand.
Confirm it against the MOT record
Before any accusation, be sure. Run the registration through our free mileage check: it lists the mileage recorded at every MOT test (Great Britain from 2005, Northern Ireland from 2017) in date order, and flags any reading lower than an earlier one automatically. Two comparisons matter:
- The dashboard now against the recorded history. If the odometer shows fewer miles than any earlier MOT recorded, it has been altered since that test. This is the clearest evidence there is.
- Drops inside the history. A fall between two past tests means the car was clocked at some point before you bought it, possibly before your seller owned it, which matters for what happens next.
One honest caveat on coverage: these are DVSA MOT readings only, one per test, so a car too young for its first MOT has none, and the check flags drops rather than judging whether an average looks right.
There are innocent explanations for an odd reading (a replacement instrument cluster after a failure, or a tester's typo corrected at the next test), and our guide to mileage correction and the law explains what legitimate paperwork looks like. So ask the seller, in writing, before you escalate: a genuine cluster swap comes with an invoice. If no evidence comes back, treat the car as misdescribed and carry on down this page.
Build your evidence file
Do this immediately. Adverts get deleted and memories get vague:
- The advert, screenshotted in full, including the mileage claim, the price and the date.
- Every message (emails, texts and messaging-app threads), especially anything discussing mileage, history or condition.
- The receipt, invoice or order form, plus any warranty paperwork.
- Service records that came with the car, which may themselves show dated mileages.
- A clearly dated photograph of the odometer as it reads now.
- The MOT history itself: save it as a PDF or print it.
Your claim is the gap between what you were told and what's true. The advert and messages prove the first half; the MOT record proves the second.
If you bought from a dealer
The Consumer Rights Act 2015 requires goods to match their description, and a car sold on a false mileage doesn't. Your remedies run on a clock:
| When | Your right |
|---|---|
| First 30 days | The short-term right to reject: hand the car back for a full refund |
| After 30 days, within 6 months | Repair or replacement first in principle, but a false mileage can't be repaired, so in practice a price reduction or the final right to reject. The burden is on the dealer to show the car was as described |
| After 6 months | Rights continue, but the burden of proof shifts to you |
Two practical notes. First, on a final rejection after the first 30 days the refund can carry a deduction for the use you've had, one reason to move fast. Second, put everything in writing: tell the dealer you're rejecting the car and why (dashboard versus MOT record, attached), set a 14-day deadline for the refund, keep copies of every letter, and keep your use of the car to a minimum while it's in dispute.
Selling on a false mileage is also a criminal misdescription under the Consumer Protection from Unfair Trading Regulations 2008. That's the reporting route below, and mentioning it in your letter tends to focus a dealer's mind.
If you bought privately
The Consumer Rights Act doesn't apply to genuine private sales, but a private sale still has rules: the car must match the description you were given. A false mileage stated in the advert or in messages is a misrepresentation, and if the seller knew it was false, it's also fraud, a police matter as well as a civil one.
The civil route is a letter before claim, then a money claim through the courts if the seller won't settle. Most car cases fit the small-claims process, which is designed to be used without a solicitor. Be realistic about two things: you'll need to identify and locate the seller, and winning a judgment isn't the same as collecting the money. That's why the evidence file matters so much.
One more check: if your "private seller" turns out to buy and sell cars regularly, they may be a disguised trader, in which case your full Consumer Rights Act rights apply after all.
The card and finance routes
How you paid can matter as much as who you bought from:
- Credit card: Section 75. If the car's cash price was over £100 and up to £30,000 and any part was paid on a credit card (even a small deposit), the card provider is jointly liable with the seller for the misrepresentation. You claim through the card provider, which is often faster than fighting the seller.
- Debit card: chargeback. Not a legal right but a card-scheme process your bank can run to reverse the payment. Time limits are strict, typically 120 days, so raise it early.
- HP or PCP finance. The finance company bought the car and supplied it to you, so the misdescription is its problem too. Complain to the lender directly with your evidence; if it isn't resolved within eight weeks, you can take the complaint to the Financial Ombudsman Service free of charge.
You can't recover the same money twice, so pick the strongest route and pursue it, keeping the others in reserve.
Report the seller
Whatever happens with your refund, report the sale to Trading Standards via the Citizens Advice consumer service on 0808 223 1133, which passes cases to your local Trading Standards office. You may not get individual updates, but reports are how patterns emerge and prosecutions happen. Clocked cars rarely travel alone.
If the seller looks organised (several cars on the go, false details, gone quiet the moment the money moved), report it to the police through Action Fraud as well (or directly to Police Scotland if you're in Scotland). Deliberate mileage fraud is a crime, not just a consumer dispute.
Realistic outcomes and timescales
Some honesty about how this tends to go:
- A clear dealer case inside 30 days (dashboard below a recorded MOT reading, advert preserved) often resolves in days to a few weeks once the evidence lands, because the dealer's position is hopeless and they know it.
- Section 75 and chargeback claims typically take a few weeks to a couple of months.
- Finance complaints run for up to eight weeks with the lender; the Financial Ombudsman adds months, but costs you nothing.
- Private court claims take several months to reach judgment, and enforcement can add more.
- Trading Standards investigations move on their own timetable, and your refund will almost always come from the civil or card routes rather than a prosecution.
If you end up keeping the car (at a renegotiated price, say), remember that the true mileage now follows it: when you eventually sell, you must disclose the discrepancy, or you'd be committing the very offence you've just been on the wrong end of.
The bottom line
Move quickly, in writing, evidence first. The 30-day rejection clock is the strongest card a dealer-bought car has, the card and finance routes are stronger than most buyers realise, and every case reported makes the next clocker's life harder. For next time: the red flags are all in how to spot a clocked car, and two minutes on the mileage timeline (plus our used car buying checklist) before you view is the whole defence.
