Guarantee vs extended warranty in the UK: what your statutory rights already cover

In the UK the words sound interchangeable, but they aren’t. Which? explains that a guarantee is usually free and offered by the manufacturer, while a warranty is more like an insurance policy — and often paid for.

Crucially, both sit alongside your legal protections. Your statutory rights under the Consumer Rights Act 2015 run in parallel and a guarantee or warranty does not replace them. Those rights can last up to six years in England, Wales and Northern Ireland, and five years in Scotland.

That’s why Which? says paid extended warranties are rarely necessary — no one has to buy one. Before you do, let OwnWise help you check the cover you already have and decide whether a fault is a quick fix or a genuine claim.
