Simply put: car insurance covers accidents and theft, while a car warranty protects against mechanical or electrical failures. Both are important drivers, but they cover very different risks.
In this guide, we’ll break down how each works, what they cover, and why many UK drivers choose to have both.
Key facts at a glance:
- Car insurance is a legal requirement in the UK
- Insurance covers accidents, theft, damage and third-party liability
- Car warranty protects against mechanical and electrical failures once the manufacturer’s ends
- Insurance covers external events (collisions, theft, vandalism)
- Without a warranty, repair bills can be costly
- A YouGov survey found that 68% of motorists worry about breakdowns
- The same study found that 78% of motorists do not have an extended warranty
- The best protection is a combination of both – insurance for accidents and damage, warranty for mechanical or electrical breakdowns
- Warrantywise offers flexible extended warranties, developed with motoring expert Quentin Wilson and overseen by Edd China for complete peace of mind
What is an extended car warranty?
An extended car warranty – sometimes called a used car warranty – is an agreement that helps protect against the cost of unexpected repairs or part failures once the manufacturer’s warranty has expired.
An extended car warranty:
- Protects against sudden or electrical breakdowns
- Offers peace of mind when keeping a car for longer
- Can be tailored with add-ons to suit your vehicle and driving needs
For example, a gearbox failure or hybrid battery replacement can cost thousands, but an having an extended warranty can help reduce the financial burden.

What is car insurance?
Car insurance is a legal requirement in the UK and protects you financially in the event of:
- Road accidents or collisions
- Theft or vandalism
- Damage to other people’s property or injury to others
- Natural events like flooding or storms (depending on your cover)

Why an extended car warranty matters:
A recent YouGov survey revealed that:
- 68% of motorists worry about potential breakdowns in their used cars
- 78% of drivers don’t have an extended warranty in place
With repair costs at record highs, this leaves many drivers financially exposed. An extended warranty acts as a safety net, helping to avoid surprise repair bills.
Always review the terms, limitations, and exclusions of any warranty to understand exactly what’s included in your plan.

Take note: Extended warranties vary so it’s important to review the warranty terms, limitations, and exclusions of the warranty plan to understand how the warranty operates.
