Key takeaways
- The UK has no statute called a lemon law — the Consumer Rights Act 2015 fills the role, and for the first 30 days it's stronger than most US versions
- US lemon laws generally require repeated failed repairs before a buyback; UK law lets you reject a faulty car outright in the first 30 days with no repair at all
- UK protection covers used cars from dealers, which many US lemon laws don't
- If you think you've bought a lemon: stop, document, and put your rejection in writing before the 30-day window closes
Search "lemon law" from the UK and you'll mostly find American answers — buyback formulas, arbitration boards, statutes with names like the Song-Beverly Act. Then the follow-up question: does Britain have one?
The literal answer is no — no UK statute is called a lemon law. The useful answer is that we don't need one, because the Consumer Rights Act 2015 already does everything a lemon law does. And if you compare the two systems honestly, the British version comes out ahead more often than not.
What a "Lemon Law" Actually Is
The term comes from the United States, where most states passed laws in the 1980s to deal with a specific problem: brand-new cars with defects the dealer couldn't fix. A typical US lemon law works on a strikes system — the manufacturer gets a set number of repair attempts (usually three or four for the same fault, or the car spending 30 days off the road) and if the problem persists, the buyer is entitled to a buyback or replacement. Claims often run through arbitration, the rules vary state by state, and in many states the law covers new cars only.
The word "lemon" for a hopelessly defective car is much older — but the legal machinery is American, which is why searching for it from Britain gets confusing fast.

The UK's Version: the Consumer Rights Act
The UK never passed a car-specific statute. Instead, the Consumer Rights Act 2015 covers every car sold by a trader — and it deals with lemons faster than the American approach:
| Typical US lemon law | UK Consumer Rights Act | |
|---|---|---|
| What's covered | Often new cars only | New and used cars from any trader |
| Before you can demand your money back | 3–4 failed repair attempts, or ~30 days off the road | Nothing — in the first 30 days you can reject outright, no repair required |
| After the initial window | Varies; manufacturer warranty period | One failed repair attempt opens the final right to reject, up to 6 months — then claims with evidence for up to 6 years |
| Who you claim against | The manufacturer | The dealer — or your finance company on HP/PCP, with the free Financial Ombudsman behind them |
| Burden of proof | Generally on the buyer | On the dealer for the first 6 months — a fault is presumed present at sale |
That first-30-days line is the one to hold onto. An American lemon owner is required to keep handing the car back for repair attempts while the strikes accumulate. A British buyer with a faulty car on day 10 can simply reject it for a full refund and be done.
"My Car Is a Lemon" — What to Actually Do
If you're here because the car you bought keeps going wrong, forget the terminology — your path is:
- Check your dates. Within 30 days of delivery, you hold the strongest consumer right in UK law. Within 6 months, the burden of proof is still on the dealer. The clock matters more than anything else, so establish where you stand today.
- Document the lemon-ness. Every fault, every date, every garage visit, every "no fault found". Photos and videos of the fault happening. The classic lemon — an intermittent fault that keeps returning — is beaten with a paper trail, not with patience.
- Reject in writing. A rejection letter citing the Consumer Rights Act to the dealer — and to your finance company if you bought on HP or PCP, since they're jointly on the hook.
- Don't accept endless repair attempts. The UK system doesn't require three strikes. After 30 days the dealer gets one shot at a repair; if the fault comes back, the final right to reject is open, and "let us have another look at it" is not something you owe them.
The One Way America Does It Better
Fairness demands one concession: several US states fund arbitration schemes with real teeth and statutory buyback formulas, which can make the endgame very mechanical once a car qualifies. The UK equivalent — the Motor Ombudsman for dealer disputes, the Financial Ombudsman where finance is involved, and the small claims court behind both — is less formulaic. But it's free, it doesn't require the car to qualify as a "lemon" by any threshold, and with the Act's presumption working for you in the first six months, you rarely need a formula.
So: no lemon law by name, a stronger one in substance. If your car's turned sour, our free eligibility check will tell you in about three minutes which of the Act's rights you're holding — and generate the letters that use them.
