Agreed Value Car Insurance: How It Works vs Market Value
Agreed value car insurance fixes the payout for a total loss or theft in writing when the policy starts, and the figure stays fixed for the policy period, which is 12 months in most cases. Market value cover pays what the insurer decides the car was worth at the time of the claim. Here is how the agreed figure is set, what happens to it at renewal, and what it costs.

What market value cover actually means
Most standard car insurance is market value cover. If your car is written off or stolen, your insurer decides what it was worth at that point, usually using an automated pricing tool, and pays out that figure. You don't know the exact number in advance, and neither does your insurer until the claim happens. For an ordinary car, that's rarely controversial. For anything better specified, lower mileage, well maintained, or simply less common than average, it can mean a settlement that falls well short of what the car would genuinely have cost to replace.
What agreed value changes
Agreed value cover fixes the figure in writing before anything happens, usually when the policy is set up. If the car is written off or stolen, that's the number you're paid, full stop. There's no negotiation at the worst possible moment, no automated tool deciding what your car was "really" worth, and nothing to dispute because it was settled in advance.
Why this matters more than people think
This isn't a theoretical concern. The Financial Conduct Authority has stated plainly that some insurers were offering customers less than their written-off or stolen vehicle was actually worth, and in some cases only increased the offer once the customer complained. That's not a rare edge case being described, it's a pattern regulators have specifically called out. An agreed value figure, backed by an independent valuation, removes the room for that kind of dispute before it can start.
How is the agreed value set?
You and the insurer agree the figure together, so it is a negotiation, not a lookup. Insurers may do their own assessment and come back with a lower number than you proposed. What they ask for varies: Howden lists the make and model, MOT and service history, receipts, photographs inside and out, and often an independent valuation, while noting that some specialist insurers hold set amounts for particular vehicles and ask for no valuation at all. For older cars, a broker's own guide says auction results and a network of clubs, dealers and specialists are the usual sources.
Does the agreed value change at renewal?
It can. The figure is fixed for the policy period, so it is reset when the policy renews, and Howden recommends renegotiating it at each renewal, usually once a year. If the car has gone up in value you are underinsured, because the payout is capped at the agreed amount, and if it has gone down you are covered for more than the car is worth. So compare the renewal schedule with your latest evidence before you pay. After modifications or a restoration, the evidence is different again, which is covered in our guide to agreed value for a modified classic.
Does agreed value cost more?
Howden says agreed value tends to be more expensive than standard car insurance, and that you may also have to pay for an independent valuation. A valuation certificate often cannot be transferred to a different insurer, so changing insurer can mean a new one. Lockton, writing as a broker, says it charges no extra premium for agreed value, so ask each insurer or broker what the figure adds to your quote.
What a proper agreed value figure needs to hold up
An agreed value isn't just a number you pick and hope your insurer accepts. It needs to be supported by genuine evidence: comparable vehicles actually on the market, adjusted for your car's specific condition, mileage and specification, with the reasoning behind the final figure documented rather than asserted. That's what makes it something an insurer takes seriously at the point of cover, rather than something that gets quietly revised down when a claim actually happens.
Frequently asked questions
What's the actual difference between agreed value and market value cover?
Market value cover pays whatever your insurer decides the car was worth at the time of loss, worked out after the event. Agreed value fixes a specific figure in writing when the policy starts, so there's nothing to negotiate later.
Is agreed value cover only for classic cars?
It's most common on classic, modified and specialist vehicles because that's where standard market-value tools struggle most, but the underlying idea applies to any car whose owner wants certainty rather than a number decided after a total loss.
Has this actually been a problem in practice?
Yes. The Financial Conduct Authority has stated that some insurers were offering customers less than their written-off or stolen vehicle was worth, in some cases only increasing the offer once the customer complained.
What do I need to get an agreed value in place?
An independent valuation report that documents the vehicle's condition, specification and comparable market evidence, submitted to your insurer before or when you take out cover, not after a claim has already started.
Does agreed value car insurance change every year?
The figure is fixed for the policy period, which is 12 months in most cases, and it is reset at renewal. Howden recommends renegotiating it each time the policy renews, so check the renewal schedule against your latest evidence.
Is agreed value car insurance more expensive?
Howden says it tends to cost more than standard car insurance, and you may need to pay for an independent valuation. Lockton says it charges no extra premium for it, so ask your insurer or broker what it adds to your quote.
