Buying a Used Car? The £1 Rule That Could Save You Thousands

When something goes wrong with a used car purchase — and sometimes it does — most buyers find out the hard way that the seller has gone quiet, the car isn't what it was described as, or getting money back is harder than it should be. The courts exist, but they're slow. The dealer's warranty, if there was one, is suddenly difficult to enforce.

Section 75 of the Consumer Credit Act 1974 is the shortcut most people never take.

If you paid any part of the purchase price on a credit card — even just £1 — your credit card provider becomes jointly liable for the seller's obligations. That means if the dealer misrepresents the car, goes bust, or simply vanishes, you can go straight to your card provider for a full refund. No courts. No chasing. No waiting to see if the dealer picks up the phone.

This isn't a loophole. It's exactly what the law was designed to do. The intention was to make credit card providers share responsibility when things go wrong, which in turn gives buyers a second route to redress without needing to take legal action themselves.

What Section 75 actually covers

Section 75 applies when:

• You paid using a credit card (not a debit card, not PayPal, not a bank transfer)
• The purchase was between £100 and £30,000
• There was a direct transaction between you and the supplier — so buying through a private seller acting as an agent may not qualify

The protection covers misrepresentation (the car wasn't what it was described as) and breach of contract (the dealer failed to deliver what they promised). Both are common in used car sales. A car described as having full service history that doesn't. A mileage that doesn't stack up. A fault the seller knew about but didn't mention. Section 75 covers all of these.

How to use it

If something goes wrong, the process is straightforward:

• Contact your credit card provider and say you want to make a Section 75 claim
• Explain what you were promised and what you actually received
• Provide evidence — the listing, any messages, photos, inspection reports
• Your card provider is legally obliged to investigate and, if your claim is valid, refund you

You should also try to resolve the issue with the dealer first — card providers will usually ask whether you've done this. But if the dealer won't engage or has disappeared, that evidence of non-response strengthens your claim, not weakens it.

What if you don't have a credit card?

This is where it gets interesting, and where most guides stop short.

You don't need to have a credit card yourself. If someone in your household has one — a partner, a parent — they can pay the £1 on their card, and as long as the card holder is the buyer named on the transaction, Section 75 applies.

If no one in your household has a credit card, get one before you buy the car. A 0% purchase credit card takes minutes to apply for online. Put £1 on it when you pay for the car. Pay it off the same day and cut it up. You're not taking on debt — you're unlocking a legal protection that already exists and costs you nothing to use.

Section 75 vs chargeback — what's the difference?

You may also have heard of chargeback — a separate mechanism that lets you dispute a transaction through your card provider. Chargeback works on both credit and debit cards, which makes it more flexible. But it's not a legal right in the same way Section 75 is. Card providers can decline a chargeback at their discretion. Section 75 is a statutory right — they can't.

If you paid by credit card, pursue Section 75 first. If you paid by debit card, chargeback is your route. If you used both, you may have both options available.

Why it matters more when buying from a dealer

Section 75 only applies to purchases from businesses, not private sellers. Which is one of the reasons dealer purchases, despite often costing more, carry more protection than private sales — and also why it matters what kind of entity you're actually buying from.

Some people selling cars from what looks like a dealership aren't actually registered businesses at all. A forecourt, a few signs, a made-up name — but no company, no legal identity, nothing to chase if it goes wrong. A real business has a card machine. If the seller is cash or bank transfer only, ask yourself why.

We rang a sample of dealers listed on AutoTrader. A striking number didn't take cards. Not because of fees — card processing costs a few pence in the pound. Because a card payment creates a paper trail, a dispute mechanism, and a route back to them if something goes wrong. A seller who won't take a card is a seller who doesn't want any comeback. A car a dealer won't stand behind isn't one you want to buy.

We looked at what people say about this on car forums. The consensus was cash is king, or dealers want to avoid card fees. Not one person mentioned Section 75. If your washing machine broke down a week after you bought it, you'd expect to get your money back. A car is the same transaction, often ten times the price, with the same legal protection available — and almost nobody knows to use it.

The standing tip we put on every page

We say this everywhere because it costs nothing and it works: pay at least £1 by credit card on any used car purchase over £100. It's the single easiest thing you can do to protect yourself, and almost nobody does it.

No other car check service will tell you this. We're not sure why.

Section 75 is a safety net, not a substitute for due diligence. The ideal outcome is that you never need it — because you already knew the seller was legitimate, the history was clean, and the car was what it claimed to be. That's what we're here for.
