Your Consumer Rights When Buying a Used Car From a Dealer

One of the genuine advantages of buying a used car from a dealership rather than a private seller is the legal protection you receive. Many buyers are not fully aware of how strong these rights are — which means they sometimes accept unsatisfactory outcomes they do not have to. Understanding the key legislation that applies to used car purchases is worth doing before you hand over any money.

The Consumer Rights Act 2015

The Consumer Rights Act 2015 is the central piece of legislation protecting used car buyers in the UK. It applies specifically to purchases made from a business — a dealership — rather than a private individual.

Under the Act, any used car sold by a dealer must meet three conditions:

Satisfactory quality — the vehicle must be of a standard that a reasonable person would consider acceptable, taking into account its age, mileage, price and how it was described at the point of sale.

Fit for purpose — the car must be capable of doing what a vehicle of that type would normally be expected to do, and any specific use you mentioned to the dealer should be accommodated.

As described — the vehicle must match any descriptions made in the listing, verbally, or in writing. If the advert stated the car had a full service history and it does not, this is a breach of the Act.

Your Rights in the First 30 Days

If a fault with the vehicle becomes apparent within 30 days of purchase, you have what the Act calls the "short-term right to reject." This means you can return the car and demand a full refund, regardless of whether the fault was present at the time of sale or developed shortly afterwards. The dealer is not permitted to insist on a repair or replacement as an alternative — the right to a full refund in this window is absolute.

You do not need to prove the fault existed at the point of sale. Within the first 30 days, it is assumed by law that any fault that appears was present when you took ownership, unless the dealer can demonstrate otherwise.

Rights Between 30 Days and Six Months

After the 30-day window closes but within six months of purchase, your rights remain strong. If a fault appears in this period, the dealer is entitled to attempt one repair or replacement before you can request a refund. Crucially, within this six-month window, the burden of proof remains with the dealer — it is their responsibility to show that the fault was not present at the time of sale, not yours to prove that it was.

If the dealer's repair attempt fails to resolve the issue, or if the fault reappears, you are then entitled to a price reduction or, in some circumstances, a full refund (though a deduction for the use you have had of the vehicle may apply).

After six months: Beyond the six-month mark, the burden of proof shifts to you as the buyer to demonstrate that the fault was present at the time of purchase. This is more difficult, but your rights under the Act continue for up to six years, so it is still worth pursuing a claim if the fault is significant and you have evidence it predates your ownership.

Private Sales: A Different Situation

It is worth being clear that these statutory rights apply only when purchasing from a business. If you buy from a private individual, the Consumer Rights Act does not apply. In private sales, the rule of "buyer beware" (caveat emptor) largely governs the transaction. The seller must not make false statements, but they are under no obligation to disclose faults they are not aware of, and there is no right to a refund simply because the car develops a problem after purchase.

This distinction is one of the most important reasons many buyers choose to purchase from a dealership rather than privately, even if the asking price is slightly higher.

What to Do If a Problem Arises

If you experience a problem with a used car bought from a dealer, contact them promptly in writing — email creates a clear record — setting out the fault and referencing the Consumer Rights Act 2015. Give them a reasonable opportunity to resolve the issue. If the dealer is unresponsive or disputes your claim, you can escalate through a certified Alternative Dispute Resolution (ADR) scheme if the dealer is a member, or seek advice from Citizens Advice or a solicitor.
