Car warranty jargon buster

Types of warranty

Manufacturer warranty

— the warranty included free with a new car, backed directly by the manufacturer.

Approved Used warranty

— a shorter warranty (commonly 12 months) that comes with a used car bought through a manufacturer's official used-car scheme.

Extended warranty

— cover bought separately, either from the manufacturer itself or a third-party provider, to extend protection beyond the original manufacturer warranty.

Service-activated warranty

— a scheme (used by Toyota, Nissan, Honda, Suzuki, Peugeot, and Citroën, among others we've researched) where cover automatically extends by a further period every time you service the car at the manufacturer's network, rather than being a fixed-length product bought upfront.

How cover is structured

FCA-regulated / insurance-backed

— a warranty that operates as a genuine insurance product, regulated by the Financial Conduct Authority, giving you access to the Financial Ombudsman Service if a dispute can't be resolved directly.

Discretionary

— a warranty that isn't insurance. The provider decides whether to pay a claim at their own discretion, rather than being bound by insurance regulation.

Listed parts / Named Component cover

— a warranty tier that only covers specifically named components, rather than the whole vehicle.

Comprehensive / All Component cover

— a warranty tier covering a much wider range of components, usually with fewer exclusions than a listed-parts tier.

Excess

— the amount you pay towards a claim yourself, with the provider covering the rest.

Claim limit

— the maximum amount a provider will pay out, either per claim or across the whole policy — often capped at the vehicle's purchase price or current market value.

Consequential damage

— damage caused to one part as a result of another covered part failing. Some warranties include this as standard; others charge extra or exclude it entirely.

Battery and EV-specific terms

State of Health (SoH)

— a measure of a battery's remaining capacity compared to when it was new, expressed as a percentage. Most EV battery warranties guarantee the battery won't drop below a set SoH threshold (commonly 70%) within the warranty period.

Traction battery

— the main high-voltage battery that powers an electric or hybrid vehicle, as distinct from the smaller 12V battery used for other electrical systems.

Other terms you'll see

Anti-perforation warranty

— cover against rust that creates a hole through the vehicle's bodywork, usually only for rust starting from the inside — not surface corrosion or external damage.

Powertrain warranty

— cover specifically for the engine, transmission, and drivetrain components, as distinct from the vehicle's electrical or cosmetic systems.

Cooling-off period

— the window (commonly 14 days under the Consumer Contracts Regulations 2013) during which you can cancel a warranty bought at a distance for a full refund.

Statutory rights

— the legal protections you have as a consumer, separate from and unaffected by any warranty — see our guide on used car warranty for how this works in practice.
