UKCan I sue for a faulty used car in small claims court in the UK?
Yes, you can sue for a faulty used car in UK small claims court — but only if the claim is £10,000 or less and you bought it from a business (not a private seller).
What the Law Says
UK consumer law protects buyers of used cars sold by businesses, even if sold 'as seen'. Private sales are largely excluded from statutory protection.
Under the Consumer Rights Act 2015, goods must be of satisfactory quality, fit for purpose, and as described — this applies to used cars sold by dealers, forecourts, or online retailers. The standard is adjusted for age, mileage, and price, but does not eliminate all rights.
The Act replaces the older Sale of Goods Act 1979 for consumer contracts and gives you clear remedies: repair, replacement, price reduction, or final right to reject within 30 days of purchase (s.24). After 30 days, you may still claim for a price reduction or damages if repair/replacement fails or is disproportionate.
Crucially, these rights apply only when buying from a trader — not a private individual. Section 2(3) of the Consumer Rights Act 2015 defines a 'trader' as a person acting for purposes relating to their trade, business, craft or profession.
Statutory TextGoods must be of satisfactory quality; this includes their state and condition and the standard a reasonable person would regard as acceptable, taking into account any description of the goods, the price and all other relevant circumstances.
— Consumer Rights Act 2015, s.9(2)
What to Do
Check whether the seller was a trader (e.g., registered business, VAT number, advertising as a dealer) — private sellers have no CRA obligations.
Gather evidence: purchase receipt, ads describing the car, service history, mechanic’s report confirming the fault, and records of all communications with the seller.
Contact the seller in writing (email or letter) demanding a remedy — e.g., repair, partial refund, or full refund — quoting the Consumer Rights Act 2015.
If unresolved after 14 days, issue a claim online via the UK Government’s Money Claim Online (MCOL) service at www.moneyclaim.gov.uk.
Prepare for hearing: submit evidence, list witnesses (e.g., mechanic), and be ready to explain how the fault breaches s.9 of the Consumer Rights Act 2015.
