Buying a used car from a dealer in the UK usually comes with some form of warranty — but the quality and coverage vary enormously. Many buyers assume a dealer warranty gives them comprehensive protection, only to discover that the exact part that failed is listed under exclusions. Understanding what your warranty actually covers, how it interacts with your statutory rights under the Consumer Rights Act 2015, and what conditions could void it entirely is essential before you sign.
What is a Warranty Terms and Exclusions?
A dealer warranty is a contractual promise from the seller (or a third-party warranty provider) to repair or replace certain vehicle components that fail within a specified period. It is separate from your statutory rights. In the UK, when you buy from a dealer (not a private seller), the Consumer Rights Act 2015 gives you legal protections regardless of the warranty — goods must be of satisfactory quality, fit for purpose, and as described. The warranty sits on top of these rights but often has far more exclusions and conditions.
Red flags to watch for
Warranties that exclude clutch, turbo, diesel particulate filter, infotainment, or electrical components leave out the most expensive and common used car repairs.
Tying warranty coverage to servicing exclusively at the selling dealer restricts your choices and can void coverage if you use a closer or cheaper garage.
Almost any mechanical failure can be attributed to 'wear and tear.' Without a clear definition, this clause gives the warranty provider an easy way to deny claims.
A warranty with a £500 per-claim limit won't cover a gearbox or engine failure, which can easily cost £2,000-£5,000.
If the warranty is sold separately (not bundled with the car price), the Consumer Contracts Regulations 2013 may give you a 14-day cooling-off period — but some dealers don't mention this.
Your legal rights
Under the Consumer Rights Act 2015, goods bought from a trader must be of satisfactory quality, fit for purpose, and as described. If a fault is discovered within 30 days, you have a short-term right to reject the vehicle for a full refund. Between 30 days and 6 months, the burden is on the dealer to prove the fault wasn't present at purchase. After 6 months, the burden shifts to you. These statutory rights exist independently of any warranty and cannot be limited or excluded by the dealer. If a dealer tells you 'it's not covered under warranty' for a fault that was present or developing at the time of sale, your statutory rights still apply. The Financial Conduct Authority also regulates warranty products sold as insurance — if the warranty is an insurance product, it must comply with ICOBS rules.
