Is a 3-Month Warranty Legally Required in the UK?
No.
There is no UK law that requires dealers to provide a 3-month warranty on used cars.
A dealer may offer one, and many do, but it is a commercial choice, not a legal obligation. The important protection does not come from a warranty at all. It comes from consumer law.
The Law That Actually Protects You: Consumer Rights Act 2015

Do not have to request it.
You do not have to pay for it.
You cannot sign it away.
Under the law, the car must be:
- Of satisfactory quality (considering age, mileage, and price)
- Fit for purpose
- As described
If it is not, the dealer is legally responsible.
Your Key Legal Rights Explained Simply
The 30-Day Right to Reject
If a serious fault appears within the first 30 days, you have the right to reject the car and request a full refund. You do not have to accept a repair during this period if you do not want to. This right alone is often stronger than any short-term warranty.
The Six-Month Presumption of Fault
If a fault appears within the first six months, the law assumes the problem existed at the time of sale. The burden of proof sits with the dealer, not the buyer.
This is one of the most misunderstood but powerful protections in UK consumer law.
Repair, Replacement, or Refund
If a fault is confirmed, the dealer must offer a repair or replacement. If that fails or is unreasonable, you may be entitled to a partial or full refund. None of this depends on a warranty.
The 3-Month Warranty Myth Explained
Why People Think It Is Law
- Dealers often advertise a 3-month warranty included
- Car buying platforms repeat the phrase
- It has been passed around for years as common knowledge
The Reality
- A warranty is a contract, not a legal right
- Consumer law applies automatically
- Legal rights override warranty exclusions
Many warranties contain restrictions, exclusions, and limits. The Consumer Rights Act does not.
Dealer Warranty vs UK Consumer Law
| Feature | 3-Month Warranty | Consumer Rights Act |
| Legally required | No | Yes |
| Cost | Often extra | Free |
| Covers faults | Limited | Broad |
| Protection length | Usually 3 months | Up to 6 months or more |
| Can be excluded | Yes | No |
This comparison is where many buyers realise they are better protected than they were led to believe.
Real-Life Situations Buyers Worry About
If the Car Breaks Down After Two Weeks
You are likely within your 30-day right to reject. You can request a refund rather than a repair.
If a Fault Appears After Three Months
Even if a warranty has ended, the law still protects you for up to six months. Your rights do not disappear when a warranty expires.
If the Dealer Says Sold as Seen
This phrase does not remove your legal rights when buying from a dealer. Consumer law still applies.
Why Dealers Focus on Warranties
Warranties are easy to market and easy to explain in a sales conversation. Legal rights are more complex and often left unmentioned.
Warranties may:
- Exclude certain faults
- Limit repair costs
- Restrict where repairs can be carried out
Consumer rights:
- Apply automatically
- Cannot be excluded
- Sit above warranty terms
A warranty can be helpful, but it should never be relied on instead of your legal rights.
What to Do If Something Goes Wrong
If your used car develops a fault, follow these steps:
- Stop driving the car if the issue is serious
- Contact the dealer in writing
- Reference the Consumer Rights Act 2015
- Clearly state whether you want a repair, replacement, or refund
- Escalate if necessary through dispute resolution or Trading Standards
Approaching the situation calmly and confidently makes a significant difference.
What If the Car Was Bought on Finance?
If the car was purchased using hire purchase, PCP, or a credit card, the finance provider may be jointly responsible. This often gives buyers additional leverage if a dispute arises.
