How to Reject a Used Car Under the Consumer Rights Act in the UK

If a dealership sold you a substandard or defective used vehicle in the United Kingdom, you are legally protected against bearing the cost. Under the Consumer Rights Act 2015, you have statutory remedies ranging from a full refund within 30 days to statutory rejection following a failed repair. Taking immediate, formal action prevents dealers from running down your statutory clocks.

Your Statutory Rights Under the Consumer Rights Act 2015 in the UK

When you purchase a used car from a commercial motor trader in the United Kingdom, the vehicle must satisfy statutory standards under the Consumer Rights Act 2015 (CRA 2015). Under Section 9, the car must be of satisfactory quality, accounting for its age, mileage, and purchase price. Under Section 10, it must be fit for any particular purpose made known to the seller, and under Section 11, it must match its description.

Dealers frequently attempt to evade statutory liability by directing buyers to third-party mechanical breakdown warranties, claiming the car was 'sold as seen,' or insisting that wear and tear explains severe mechanical failures. Section 31 of the CRA 2015 renders any contract term that tries to exclude or restrict these statutory rights entirely unenforceable. If you bought the car as an individual from a motor trade business, these protections are mandatory and non-negotiable.

The 30-Day Window versus the Final Right to Reject

Your remedies depend strictly on when you notify the dealer of the non-conformity. Under Section 22 of the CRA 2015, you have a 'short-term right to reject' within the first 30 calendar days following purchase and delivery. If the car has a demonstrable fault that was present or developing at the time of delivery, you are entitled to a 100% refund. Under Section 20(17) and 20(18), the dealer cannot make any deduction for usage or mileage within this initial 30-day window.

Between day 31 and month 6, Section 19(14) establishes a reverse burden of proof: the law presumes any defect was present at delivery unless the dealer can prove otherwise. Under Section 23, the dealer is entitled to one single attempt to repair or replace the car. If that repair fails, is refused, or cannot be carried out within a reasonable time and without significant inconvenience, you can trigger your 'final right to reject' under Section 24. While Section 24(10)(a) permits a fair deduction for usage on motor vehicles, the dealer must return the remainder of your purchase price without unnecessary delay.

Holding Uncooperative Dealerships Accountable

Car dealers often stall communications in the hope that you exceed statutory deadlines or rack up mileage that weakens your position. The moment a critical fault emerges, you must create a clear, date-stamped paper trail. Stop driving the car, notify the seller in writing that you are formally rejecting the vehicle under the Consumer Rights Act 2015, and state whether you are exercising the short-term right to reject (Section 22) or the final right to reject (Section 24). If the purchase involved hire purchase or PCP finance, the finance provider owns the car and shares direct liability.

You do not have to fight a recalcitrant dealership on your own. You can use Caunsel to research statutory precedents, store your repair logs and dealer correspondence in a single organized case file, or connect directly with an independent consumer lawyer to formally demand your refund.

Steps

• Cease driving the car immediately; continued use after discovering a serious defect can be treated as acceptance or lead to hefty mileage deductions.
• Obtain independent diagnostic evidence, such as an MOT failure sheet, an RAC/AA inspection report, or written findings from an independent garage.
• Draft a formal 'Notice of Rejection' email and letter specifying the vehicle details, the exact faults, the relevant provisions of the Consumer Rights Act 2015, and a strict 14-day deadline for your refund.
• If the vehicle was acquired on finance (PCP or Hire Purchase), send an identical rejection notice to the finance company, demanding an immediate freeze on payments and cancellation of the agreement.
• If the trader ignores or refuses your statutory rejection, submit a complaint to their designated Alternative Dispute Resolution (ADR) body, such as The Motor Ombudsman, or issue a formal Letter Before Claim under the Pre-Action Protocol.

Common mistakes

• Continuing to drive the car for commuting or leisure after notifying the dealer of rejection, which dealers use to argue the fault is non-fundamental or to claim large usage deductions.
• Allowing the dealer multiple 'courtesy' repair attempts after day 30, forfeiting your clear single-repair threshold under Section 24 of the CRA 2015.
• Relying solely on phone conversations instead of establishing a verifiable written record of every fault, date, and conversation.
• Accepting a referral to a third-party warranty policy rather than asserting your primary legal claim directly against the selling dealership.

Questions people ask

Can a dealer deduct money for mileage if I reject the car within the first 30 days?

No. Under Section 20(17) and 20(18) of the Consumer Rights Act 2015, if you exercise your short-term right to reject within 30 days of purchase or delivery, you are entitled to a full refund without any deduction for use or mileage.

What happens if I bought the car on PCP or Hire Purchase?

Under a PCP or Hire Purchase agreement, the finance company is the legal owner and supplier of the vehicle. You must direct your statutory rejection to the finance provider as well as the dealer; the finance company is jointly responsible under the Consumer Rights Act 2015 and Consumer Credit Act 1974.

Can a dealer avoid a rejection by stating the car was sold as seen or trade sale?

No. Section 31 of the Consumer Rights Act 2015 makes it illegal for a commercial trader selling to a consumer to contract out of their statutory obligations. Phrases like 'sold as seen' or 'trade sale only' are void and do not eliminate your right to reject.
