As there is no underwriter for a non-insured warranty, there is a finite “money pot” to cover the cost of any claims. Once this runs out they can’t cover any further claims, potentially leaving you with a broken-down vehicle and having to cover the costs yourself AND no recourse or redress other than the company itself!
Overall it is a much safer option to opt for an insured warranty – with this you have the protection of the FCA, the Ombudsman and the Compensation Scheme, should you need it.
With a non-insured warranty you’re left at the mercy of the company themselves, with no independent remedy options if things go wrong.
