A courtesy car is an add-on, not a right

This is written to be used rather than admired. Each section below is a decision about courtesy car cover, and each one has a default.

What the standard benefit covers

Most comprehensive policies provide a courtesy car while your vehicle is being repaired by the insurer's approved repairer. It is a repair-network benefit rather than a general mobility benefit, which is the distinction that catches people.

Use an independent garage instead and the entitlement usually disappears. That is one of the practical costs of choosing your own repairer.

The total-loss gap

If the vehicle is written off there is no repair, so the courtesy car benefit typically ends immediately or within a short grace period. This is precisely when you are without a vehicle for the longest, since settlement negotiation and buying a replacement take weeks.

Guaranteed hire vehicle cover is a separate add-on that provides a car for a stated number of days regardless of repairability. That add-on is the one that addresses the actual gap, and it is not what most people assume they already have.

Size is not matched

Courtesy vehicles are commonly small hatchbacks regardless of what you drive. Like-for-like replacement is an upgraded benefit and costs more.

On an ordinary week, for anyone whose vehicle carries a family, tows, or is needed for work, that difference is not cosmetic. Check the class of vehicle promised, not just whether a vehicle is promised.

Non-fault accidents work differently

Where another party is at fault, a credit hire company or the other insurer may provide a replacement, sometimes like for like. Credit hire arrangements can carry high daily rates recoverable from the at-fault insurer, and you may be personally liable if recovery fails. Signing a credit hire agreement without reading the liability clause is a genuine risk.

Your own insurer will usually explain the alternatives if asked directly.

Duration limits

Guaranteed hire products state a maximum number of days, commonly two to four weeks. Parts shortages and repair backlogs have pushed repair times well beyond historic norms in several markets.

A limit that once comfortably covered a repair may no longer do so. The number of days is therefore worth checking at renewal rather than assumed to be adequate.

None of this is a substitute for talking to a clinician if something feels wrong.

Deciding whether to buy it

The test is what it would cost you to be without a vehicle for a month, including hire, lost work or alternative transport. For a household with a second vehicle, the answer is often very little. For a sole vehicle used to get to work, the add-on is usually cheap relative to the exposure.

This is a straightforward arithmetic comparison rather than a judgement call.

The takeaway

The benefit you probably have ends at write-off. The one that helps then is a separate purchase.

The version you keep doing is the version that works.
