Agreed value cover allows you to insure your minibus for a specific sum agreed between you and the insurer at the time the policy is set up. In the event of a total loss, you receive the agreed value regardless of what the market value is at that time.
Agreed value cover is a feature of commercial motor insurance that provides financial certainty in the event of a total loss — a vehicle that is written off following a collision, fire, or theft. Understanding how it works, when it is appropriate, and how to set the right agreed value helps operators avoid one of the most common and costly errors in minibus insurance: discovering that a market-value policy pays out far less than expected.
How Agreed Value Works
When you take out an agreed value policy, you and the insurer agree at the outset on the sum insured for the vehicle. This agreed value is endorsed on the policy. If the vehicle is subsequently written off — declared a total loss by the insurer following an incident — the insurer pays the agreed value in full, less any applicable excess.
The key difference from a market value policy is certainty. A market value policy pays what the insurer assesses the vehicle was worth on the open market at the time of loss. If the vehicle has depreciated significantly, or if the insurer's market assessment is conservative, the payout may be considerably less than the operator expected — and potentially less than the replacement cost.
The Problem with Market Value Policies for Minibuses
Minibuses depreciate at different rates to standard cars. An older HiAce or Mitsubishi Rosa used for school transport may have a low market value but remains fully operational and cost more in maintenance and upkeep to keep at that standard. A replacement will cost the operator far more than the market write-off payout.
More significantly, modified minibuses — wheelchair accessible vehicles, vehicles with fitted seating configurations, tourism vehicles with roof racks and specialist fittings — carry modification costs that are invisible in standard market value assessments. A base vehicle worth $20,000 with $60,000 in wheelchair accessibility modifications has a true replacement cost of $80,000, but a market value assessment may yield only $20,000–$25,000.
Setting the Right Agreed Value
The agreed value should reflect the true replacement cost of the vehicle — not just its current market value. For standard minibuses, this means checking current dealer prices for equivalent vehicles at the same specification, age, and condition. For modified vehicles, it means adding the full cost of modifications to the base vehicle replacement cost.
Agreed values should be reviewed annually. Minibus values fluctuate, replacement parts availability changes, and modification costs change over time. Setting an agreed value and leaving it unchanged for three years may result in under-insurance if costs have increased.
Agreed Value and Fleet Policies
Fleet policies can include agreed values for each vehicle in the fleet schedule. Each vehicle's agreed value should be individually assessed — a five-year-old HiAce will have a different agreed value than a three-year-old WAV, and each should reflect the true cost of replacing that specific asset.
When onboarding a fleet to a new insurer, providing a detailed fleet register with the replacement cost assessment for each vehicle helps the insurer accurately set agreed values and avoids underinsurance disputes at claim time.
New Vehicles vs Older Vehicles
For new or near-new minibuses, agreed value cover is particularly valuable because it protects against the sharp depreciation that occurs in the first few years of a vehicle's life. A brand-new minibus purchased for $95,000 might have a market value of $65,000 two years later — but the agreed value set at inception still pays $95,000 (less any policy-level depreciation adjustments agreed at inception).
For older vehicles with genuinely low market values, the premium difference between market value and agreed value cover narrows, and the decision becomes less financially significant. But for any vehicle with modifications, equipment, or specialist fittings, agreed value is almost always the right choice regardless of age.

Who This Cover Suits
Frequently Asked Questions
Why is agreed value better than market value for a minibus?
Market value fluctuates with depreciation and market conditions, meaning a write-off payout may be significantly less than you expect. Agreed value provides certainty — you know exactly what you will receive in a total loss. For modified vehicles, agreed value captures the full replacement cost including modifications.
How do I set the right agreed value for my minibus?
The agreed value should reflect the current replacement cost — what it would cost to buy an equivalent vehicle today. For modified vehicles, include the cost of modifications. Check current dealer prices for comparable vehicles and discuss the appropriate agreed value with your broker annually.
Does agreed value cover apply to repairs as well as total loss?
No. Agreed value applies specifically to total loss payouts. Partial loss claims (repairs to a damaged vehicle) are handled on the basis of actual repair costs, regardless of the agreed value. The agreed value only determines the payout when the vehicle is written off.
Is agreed value cover more expensive than market value?
The premium for agreed value cover is typically slightly higher than market value, as the insurer is committing to a known, higher payout in a total loss scenario. However, the premium difference is usually modest, and the financial certainty it provides — especially for modified or high-value vehicles — is well worth the cost.
What happens if I don't review my agreed value annually?
If your agreed value falls below the true replacement cost, you may be under-insured. Conversely, if vehicle values fall and you don't adjust, you may be paying for more cover than necessary. Reviewing the agreed value at each annual renewal is good practice and something your broker should prompt you to do.
