Warranty vs guarantee: what protection do you actually have?

Quick answer: A guarantee is a promise from the manufacturer or seller that a product will work for a set period — repairs or replacements are free. A warranty is an insurance contract you buy separately that covers repairs after the guarantee expires.
When you buy a washing machine, car, or phone, you are offered guarantees and warranties — often with confusing overlap. Understanding the difference helps you decide whether to pay for extended cover or rely on your legal rights under the Consumer Rights Act.
Manufacturer guarantees
A guarantee is a manufacturer's promise that the product will work for a specified period. If it fails, they repair or replace it free. Guarantees are included at no extra cost.
Guarantees do not usually cover accidental damage, misuse, or wear and tear. They cover defects in materials or workmanship.
Extended warranties
Extended warranties are insurance policies sold by retailers or third parties covering repairs after the guarantee expires. They cost money — often £50–£300 depending on the product.
They are regulated by the FCA as insurance contracts. Read the exclusions carefully: many do not cover the most common failure types.
Your legal rights without any warranty
The Consumer Rights Act 2015 gives you the right to reject faulty goods within 30 days for a full refund. Within six years (five in Scotland), you can claim repair or replacement for faults that were present at purchase.
These statutory rights often provide better protection than paid warranties, which is why many consumer advocates advise against buying extended warranties.
Common questions
Should I buy an extended warranty?
Usually not. Your Consumer Rights Act protections are often stronger. Extended warranties make sense only for expensive items where repair costs would be very high and the warranty covers specific risks not covered by law.
Does a guarantee affect my legal rights?
No. Your statutory rights under the Consumer Rights Act exist independently of any guarantee or warranty. A guarantee cannot reduce your legal rights.
Can I claim under both a guarantee and the Consumer Rights Act?
You claim under whichever gives you the best outcome. If the guarantee covers the fault, use it. If not, your statutory rights may still apply.
