Probate vs Insurance Valuation — What's the Difference?
In brief
A probate valuation reports Open Market Value at the date of death for HMRC. An insurance valuation reports the retail cost of replacing an item today. The insurance figure is usually the higher of the two, so copying it into the estate return can overstate the estate. Both figures can often be prepared in one appointment, but they must be issued and used separately.
The Key Difference
Insurance valuations and probate valuations may both involve the same item, but they answer fundamentally different questions. An insurance valuation asks: "How much would it cost to replace this item today?" A probate valuation asks: "What would this item fetch if sold on the open market on the date of death?"
These two questions produce very different figures. An insurance valuation is almost always higher than a probate valuation, sometimes by a considerable margin. Using the wrong type of valuation can result in overpaying Inheritance Tax, underpaying it, or having your estate assessment challenged by HMRC.
Understanding which valuation you need — and when — is one of the most important responsibilities facing an executor.
Open Market Value Explained
Probate valuations are based on Open Market Value (OMV). This is defined as the price an item would reasonably be expected to fetch if sold on the open market at the date of death. In practice, this often equates to the price the item might achieve at auction.
Open Market Value takes into account the condition of the item, current market demand, and comparable recent sales. It does not factor in sentimental value, original purchase price, or what it would cost to buy a replacement.
For HMRC purposes, the date of death is critical. Market conditions on that specific date determine the value, not what the item was worth a year earlier or might be worth in the future. For valuable or difficult-to-value assets, a professional with relevant market evidence can provide a stronger basis than an unsupported estimate.

Insurance Replacement Value Explained
Insurance valuations are based on replacement value — the cost of replacing an item with one of equivalent type, quality, and condition from a retail source. This figure is designed to ensure that, if the item is lost, stolen, or damaged, the policyholder receives enough compensation to buy a like-for-like replacement.
Because retail prices can include dealer margins, VAT and other overheads, an insurance replacement value is often higher than Open Market Value. The size of the difference varies widely by item and market.
Insurance valuations are updated periodically — usually every three to five years — to reflect changes in retail prices and market conditions. They are not tied to a specific date of death and cannot be used in place of a probate valuation.
Why Using the Wrong Valuation Matters
An insurance valuation uses the wrong basis for an Inheritance Tax asset value. Because replacement values are often higher, relying on one may overstate the estate and, where the estate is taxable, may cause too much tax to be reported or paid.
Conversely, if a probate valuation is used for insurance purposes, the item will be underinsured. In the event of a claim, the payout would not be sufficient to replace the item.
The consequences of using the wrong type of valuation can be summarised as follows:
- Using insurance values for probate — may overstate the estate and any tax calculated from it
- Using probate values for insurance — understates the replacement cost, leaving items inadequately covered
- Using outdated valuations for either purpose — may not reflect current market conditions, leading to inaccurate reporting
Side-by-Side Comparison
The following table summarises the key differences between insurance and probate valuations. Referring to this comparison can help you ensure that the correct type of valuation is used for each purpose.
| Feature | Probate Valuation | Insurance Valuation |
|---|---|---|
| Purpose | Inheritance Tax reporting to HMRC | Insuring items against loss, theft, or damage |
| Basis of value | Open Market Value (auction price) | Retail replacement cost |
| Typical figure | Lower — reflects what a buyer would pay at auction | Higher — reflects retail replacement cost including margins |
| Date sensitivity | Must reflect value at date of death | Reflects current retail prices; updated periodically |
| Who accepts it | HMRC, probate courts, solicitors | Insurance companies |
| Methodology | Auction records, trade databases, market comparables | Retail price research, manufacturer pricing, trade sources |
| Typical validity | Specific to the date of death | Usually valid for 3–5 years, then requires updating |
Do You Need Both Probate and Insurance Valuations?
Executors often ask whether probate and insurance valuations can be handled together. In many estates the answer is that both figures are genuinely needed, but for different reasons and at different points in the administration.
The estate needs Open Market Value at the date of death to report the assets correctly. Separately, once items pass to beneficiaries, whoever keeps them may need current replacement cover — and the probate figure will usually be too low to insure against. Items being retained rather than sold are the ones most likely to need both.
Where insurance and probate valuations are commissioned together, a suitably experienced valuer can inspect once and produce two reports. What matters is that the reports stay separate documents, each stating its basis of value and its effective date, so that neither figure is later used for the wrong purpose.
- Items being sold during the administration — the estate generally needs the probate figure, not an insurance one
- Items passing to a beneficiary who will keep them — a probate figure for the estate, and a current replacement figure for the beneficiary to insure
- Items already covered by an existing insurance valuation — useful for identification and description, but not a substitute for Open Market Value
- Items of modest value — a reasonable estimate may be proportionate; keep a note of how you arrived at the figure
Getting the Right Valuation
When instructing a valuer, it is essential to specify clearly whether you require a probate valuation, an insurance valuation, or both. Many qualified valuers can provide both types in a single appointment, but they must be reported separately and used only for their intended purpose.
If the deceased held existing insurance valuations, these can be useful reference points but must not be submitted to HMRC as probate values. Similarly, if you obtain a probate valuation during the estate administration, do not rely on it for ongoing insurance cover of items that are being retained by beneficiaries.
A qualified valuer will understand the distinction and ensure that each valuation is prepared using the correct methodology. If you are unsure which type you need, a professional can advise you based on your specific circumstances.

Frequently Asked Questions
01Do I need both insurance and probate valuations?
It depends on what will happen to the item. The estate needs a reasonable Open Market Value at the date of death, while a beneficiary retaining and insuring an item may need a current replacement valuation. A suitably experienced valuer may be able to prepare both figures in one appointment, issued separately for their different purposes.
02Can I use an existing insurance valuation for probate?
Not as the Open Market Value figure by itself. An insurance report may help identify and describe the item, but its replacement-value basis is different and is often higher. The estate needs evidence of Open Market Value at the date of death; professional input is sensible where that value is uncertain or potentially significant.
03Why is the probate value of my jewellery so much lower than the insurance value?
Probate valuations reflect Open Market Value — what the item might fetch on the open market — while insurance valuations reflect replacement cost, which can include dealer margins, VAT and other overheads. It is common for the insurance figure to be higher, but the difference varies by item.
04Can the same valuer provide both insurance and probate valuations?
Yes, provided they are suitably qualified. Many professional valuers routinely provide both types of valuation and can do so during a single inspection. However, each valuation will be prepared using a different methodology, and the resulting figures will differ. The two valuations should be issued as separate documents for their respective purposes.
