Buying from a dealer gives you Consumer Rights Act 2015 protection — the car must be of satisfactory quality, fit for purpose and as described, with a 30-day right to reject and a six-month repair/replace presumption. A private sale is covered only by "as described" under the Sale of Goods Act, with no satisfactory-quality guarantee — it's largely caveat emptor, so an independent inspection and vehicle history check matter far more.
Dealer vs private sale protections
| Protection | Dealer sale | Private sale |
|---|---|---|
| Satisfactory quality guarantee | Yes (Consumer Rights Act 2015) | No |
| 30-day right to reject | Yes | No |
| 6-month repair/replace presumption | Yes | No |
| "As described" protection | Yes | Yes (limited) |
| Typical price | Higher | Lower |
What the Consumer Rights Act 2015 gives you at a dealer
Buying a used car from a dealer in the UK means the car must be of satisfactory quality (accounting for its age, mileage and price), fit for its intended purpose, and match its description. Within the first 30 days, you generally have the right to reject the car and get a full refund if something is seriously wrong. For the first six months, if a fault appears, the law presumes it was present at the time of sale unless the dealer can prove otherwise — after that, the burden shifts to you to prove the fault existed at purchase.
Why private sales are different
A private seller only has to sell a car that matches its description — there is no requirement that it be of satisfactory quality or fit for purpose. This is the traditional "buyer beware" (caveat emptor) principle, and it means a private seller can knowingly or unknowingly sell a car with a serious fault and you'll have very limited legal recourse unless you can prove they lied about a specific factual claim they made.
What "as described" still protects you against
Even in a private sale, if the seller makes a specific false claim — for example, stating the car has never been in an accident when it has, or misstating the mileage — you may have a claim for misrepresentation. The practical difficulty is proving what was said and relying on it, which is why written communication (messages, the advert text) matters.
How to protect yourself in a private sale
- Get an independent vehicle history check (HPI-type check) covering outstanding finance, write-off status, stolen record and mileage discrepancies.
- Have the car independently inspected before paying, especially for anything beyond a very cheap runabout.
- Get everything the seller tells you about the car's history in writing — text messages or email count.
- Meet at the registered keeper's address where possible, and verify the V5C details match.
- Pay via a traceable method and never send a deposit before viewing the car in person.
Some private-seller-style ads are actually placed by unlicensed traders posing as private individuals to avoid Consumer Rights Act obligations. If a "private" seller has multiple cars listed, or the ad reads like a dealer listing, ask directly whether they're selling in the course of business — this affects your legal protection.
Weighing price against protection
Private sales are typically cheaper than the same car from a dealer, partly because the price doesn't need to fund dealer margin or warranty backing. Whether that trade-off makes sense depends on your appetite for risk and your ability (or willingness to pay someone) to properly vet the car before buying.
