Market value cover pays what your item would fetch immediately before the loss. Agreed value cover pays a figure you and the insurer fixed in advance, usually supported by a valuation, regardless of what the market would have said on the day. For anything whose worth is argued about rather than looked up, classic and modified cars above all, the difference decides whether a total loss is a settlement or a dispute.

The two phrases look interchangeable on a quote screen. At claim time they are opposites: one is an open question answered by the insurer’s engineer after the loss, the other is a number already written down.

How market value works

The policy promises the reasonable market value at the time of loss, and the insurer’s assessor determines it, typically from trade guides and comparable sales. For an ordinary car or a mainstream possession that mechanism is fine, because the comparables exist and cluster tightly.

It breaks down where comparables are thin or the item is not average: the restored car that is worth double the guide price, the low-mileage exception, the modified vehicle, the collection assembled over decades. The assessor is not wrong to use the guides; the guides are just not about your item.

How agreed value works

You establish the value before cover starts, usually with photographs and a valuation from a recognised club or specialist, and the insurer accepts a stated figure. If the item is a total loss, that figure is the settlement. The argument that would have happened after the loss happens before it instead, when it is calm, cheap and optional.

Agreed value is standard practice in the classic car market and available more widely through specialist insurers. It is not the same thing as the sum insured on an ordinary policy, which is a ceiling, not a promise.

The trap between the two

Many policies for interesting vehicles are sold as market value with the option of agreeing a value, and the option never gets exercised. The owner believes the insurer knows what the car is worth because the premium felt right. The premium is not a valuation, and neither is the sum insured proposed on the quote. If the value matters, it needs agreeing, in writing, with the evidence attached.

Valuations also age. An agreed value from years ago, in a market that has moved, quietly becomes a market value problem in reverse.

Common questions

Is agreed value more expensive?

Often only modestly, and sometimes not at all through specialist schemes: insurers price certainty too. The cost that matters is the valuation effort up front.

Does the sum insured on my policy mean the insurer agreed that value?

No. On a market value policy the sum insured is normally a maximum, not a promise. Unless the policy says the value is agreed, it is not.

What evidence supports an agreed value?

Typically photographs, a specialist or owners’ club valuation, restoration invoices and provenance. The stronger the file, the smoother both the agreement and any later claim.

How often should an agreed value be reviewed?

At renewal, against the state of the market. A figure agreed in a rising market and left alone can be badly stale in a few years.

Is this only about cars?

Cars are the classic case, but the same logic applies wherever value is argued rather than looked up: collections, high-value contents and items with provenance.
