Is an approved used car always backed by a warranty in the UK?

No. "Approved used" is a manufacturer or retailer programme, not a legal category, so nothing in UK law defines it, requires it to include a warranty, or sets how long that warranty must last. Two cars both advertised as approved used can carry completely different cover, and the badge alone tells you nothing about what you would be entitled to. What every used car bought from a trader does carry, approved or not, is the Consumer Rights Act 2015 — which cannot be excluded by a contract term, a sign, or the words "sold as seen", and which is stronger than most warranties on the faults it covers.

“Approved used” is a brand, not a standard

Each manufacturer runs its own programme with its own name, its own checklist and its own warranty terms, and sets them itself. There is no external body certifying what the phrase means and no minimum any programme has to meet, so the length of cover, the mileage cap, the exclusions and whether the warranty follows the car to its next owner all vary by brand and can change between model years. Comparing two approved-used cars from different makers is comparing two different contracts that happen to share an adjective.

That is not a reason to avoid them. A good programme really does add a multi-point inspection, a warranty and sometimes breakdown cover. It is a reason to read the warranty document rather than the badge, because the badge is the one part of the offer that carries no obligations.

UK law sets no minimum warranty on a used car

No UK law requires a dealer to give a warranty, and none sets a minimum length. Every trade sale carries the Consumer Rights Act 2015 instead, which is stronger than most warranties and cannot be excluded by a contract term, a sign, or the words "sold as seen". A warranty is what a dealer adds on top.

Consumer Rights Act 2015 s.31 (terms excluding these rights are not binding on the consumer)

What you get whether the car is “approved” or not

Buy from a trader and the Consumer Rights Act 2015 applies to the sale, with or without a warranty and whatever the advert called the car. It is the floor beneath every used-car purchase from a business, it cannot be excluded, and on the faults it covers it is generally stronger than a warranty because a warranty is free to write its own exclusions. The detail of what you can require and when is set out in what your rights are if a used car breaks down, and how a dealer warranty sits on top of it in the used-car warranty guide.

The practical consequence is worth stating plainly: if a dealer offers you an extended warranty and implies you are unprotected without it, that is not right. You are already protected. The extended warranty is worth buying when it covers something your statutory rights do not — later mechanical wear, most often — and not because it fills a gap in the law.

Questions people ask

Does UK law set a minimum warranty on a used car?
No. No UK law requires a dealer to give a warranty at all, and none sets a minimum length. What the law gives you instead is the Consumer Rights Act 2015, which applies to every trade sale and cannot be signed away. A warranty is something a dealer adds on top of that, not a substitute for it.
What should I actually check before relying on an approved used warranty?
Get the warranty document itself rather than the badge. The things that decide whether it is worth anything are its length in months, whether it also carries a mileage cap, what it excludes, whether it covers labour as well as parts, whether it is limited to the selling dealer or honoured across the network, and whether it survives being sold on. A programme name answers none of those.
Is a dealer warranty better than my statutory rights?
Usually not, for the faults both cover. A warranty is a contract and can exclude whatever it says it excludes, including wear items and anything it decides was pre-existing. Your statutory rights cannot be excluded and put the burden on the dealer for the first six months. The warranty is worth having because it can cover things the Act does not, such as a component that simply wears out later.
Does buying privately change any of this?
Yes, substantially. The Consumer Rights Act applies to traders, not to private sellers. Buying from a private seller the car only has to be as described — there is no satisfactory-quality or fit-for-purpose standard to fall back on, and no approved-used programme exists to add one.
