The Consumer Rights Act for used car dealers
The short answer
A car you sell to a consumer must be of satisfactory quality, fit for purpose and as described, judged against its age, price and mileage. Within 30 days the buyer can reject it for a full refund; after that you get one chance to repair or replace, then they can reject it or ask for money off. A fault that appears in the first six months is taken to have been there at the sale unless you show otherwise.
The Consumer Rights Act 2015 sets what a buyer can expect from a car you sell them, and what they can ask for if it goes wrong. It applies when you sell to a consumer: someone buying “wholly or mainly” outside their own trade or business (section 2).
What the car has to be
Every sale includes three promises:
- Satisfactory quality. What a reasonable person would expect, including freedom from minor defects, safety and durability (section 9). For a used car that takes account of its age, price and history, including mileage, and some wear and tear is expected (Business Companion).
- Fit for purpose, including any purpose the buyer told you about (section 10).
- As described, in the advert, the listing and what you say (section 11).
Anything you specifically point out to the buyer before the sale is not covered by the quality promise (section 9(4)). That is why showing the MOT record and its advisories in writing matters.
What the buyer can ask for, and when
| When | What the buyer can do |
|---|---|
| Within 30 days | Reject the car for a full refund (section 22). Days it spends back with you for repairs do not count (Business Companion). |
| After 30 days | Ask for a repair or replacement, which you must do within a reasonable time, without significant inconvenience and at your cost (section 23). |
| If that fails | Reject the car or keep it with money off (section 24). On a final rejection you can deduct for use, including in the first six months, because the Act makes an exception for motor vehicles. |
The six-month rule
A fault that shows up within six months of delivery is taken to have been there when you sold the car (section 19(14)), unless you can show the car was right on the day (section 19(15)). A record of the car’s condition at the sale is how you show it: the MOT history, what you checked and fixed, and what you told the buyer.
Selling online or at a distance
If the buyer orders without coming in, for example online, and collects later, it is a distance sale. They can also cancel within 14 days of taking the car (Consumer Contracts Regulations, regulation 30). A sale agreed and signed at your premises has no cooling-off period (Business Companion).
Selling to another trader
The Act does not apply. The Sale of Goods Act 1979 still implies that goods sold in the course of a business are of satisfactory quality (section 14).
A record of the car at the sale
A trade report gives you that record in one document: the MOT history word for word, the mileage at every test, and a checklist for the handover that ends with the paperwork:
- Service history: stamped book or invoices
- V5C logbook in the seller’s name
- Latest MOT certificate
- All keys, including the spare
Give the buyer a copy and keep one with the sale paperwork.
Frequently asked questions
Can I sell a car “sold as seen” to a consumer?
No. Trading standards guidance says sellers cannot use words such as “sold as seen” in sales to consumers to take away their rights.
Does the 30-day right to reject include time in the workshop?
No. Trading standards guidance says the 30 days do not include days the car is back in the garage for repairs.
Can I take something off a refund for the miles the buyer has done?
On the final right to reject, yes. For most goods no deduction is allowed in the first six months, but the Act makes an exception for motor vehicles.
Does the Act cover selling to another trader?
No. It protects consumers. A sale to a business falls under the Sale of Goods Act 1979, which also implies that goods sold in the course of a business are of satisfactory quality.
How long can a buyer bring a claim?
In England and Wales, up to six years from the date they bought the car. In Scotland, within five years of discovering the fault.
