When administering a deceased estate in the UK, executors are required to provide HMRC with a valuation of the estate's assets — including watches, jewellery, and other personal property — as part of the inheritance tax assessment process. Getting this wrong — either through undervaluation or overvaluation — can have consequences for the estate and for your obligations as executor.
This guide explains what HMRC requires, the three types of valuation and which one you need, and how to obtain appropriate documentation for watches and jewellery.
What HMRC requires for watches and jewellery
HMRC's guidance on valuing personal possessions for inheritance tax purposes states that personal items should be valued at the price they might reasonably be expected to fetch if sold in the open market at the date of death. This is described as the "open market value" — not the insurance replacement value, and not the price a charity shop might pay.
For common household items with a total value below £1,500, HMRC accepts a broad estimate. For individual items worth more than £500, or collections with a combined value that is significant, HMRC expects a more rigorous assessment — and may require professional documentation.
For watches and jewellery collections of any meaningful value, a written specialist assessment is the appropriate approach. This should include a description of each item, its condition, and an assessed open market value.
The three types of valuation — and which you need
Open market value
What the item would sell for between a willing buyer and a willing seller at the date of death. This is what you need for inheritance tax purposes. Lower than insurance value.
Replacement value
What it would cost to replace the item at retail. Typically 30–60% higher than open market value. Do not use insurance valuations for probate purposes — it may overstate the taxable estate.
Estimate / reserve
What an auctioneer expects the item to sell for at auction. Typically lower than open market value for common items (reflecting auction uncertainty) and higher for exceptional pieces.
For inheritance tax purposes, you need the open market value — the realistic selling price in the current market, not the insurance replacement cost.
Who can provide a probate valuation for watches and jewellery?
HMRC does not require valuations to be conducted by a specific professional — but it does require that the valuation is reasonable and supportable. For watches and jewellery, an appropriate valuation comes from:
- A specialist watch and jewellery buyer with market knowledge
- An auction house specialising in watches and jewellery
- A fellow of the Gemological Association of Great Britain (for jewellery-specific valuations)
What is not appropriate for significant items is a generalist estimate from a jeweller or antique shop who lacks the specific market knowledge to assess collector value above intrinsic metal value.
Fair Vintage provides a written valuation schedule with every estate assessment — listing each item, its description, and its assessed open market value. This documentation is suitable for estate administration records and provides the written evidence of a professional market assessment that HMRC may request. If you sell to us, there is no additional charge for the documentation.
Common valuation mistakes in estate administration
Using insurance values
Insurance replacement values are typically 30–60% above market selling prices. Using them as probate values risks overstating the taxable estate and creating unnecessary inheritance tax liability. Always use open market values for inheritance tax purposes.
Assuming watches are worth face-price or nothing
A £50 watch purchased in 1975 may now be worth £5,000 as a collectible. Equally, a watch purchased in 2005 for £8,000 may now sell for £3,000. Neither original purchase price nor current retail price is a reliable guide to current market value. Assessment is necessary.
Disposing of items before assessment
Executors who dispose of items — giving them to family members, charity, or dealers — before obtaining a formal valuation may face difficulty establishing the values for HMRC purposes, and may also be exposed to claims from beneficiaries if items are disposed of below fair value. Always assess before disposing.
The practical steps for executors
- Inventory everything — list all watches and jewellery found in the estate, even items that appear to have no value
- Photograph everything — including casebacks, hallmarks, maker's marks, and any original boxes or certificates
- Do not clean, polish, or repair — original condition is what needs to be assessed
- Obtain a written specialist assessment — with per-item values and descriptions
- Keep all documentation — the written valuation schedule should be retained with the estate administration records
- Report the values to HMRC as part of the IHT400 form, using the assessed open market values
HMRC may query valuations, particularly if they appear inconsistent with known market prices. A written professional assessment from a specialist buyer or auctioneer provides the evidence to support your figure. If you have sold the items, the actual sale price is the most compelling evidence of market value. HMRC's Shares and Assets Valuation team handles disputed non-property valuations.
Yes — and you should. The valuation is needed to complete the inheritance tax forms, which are typically required before probate is granted. You do not need probate to have items assessed — you are the executor or administrator and may take possession of and assess personal property as part of your duties.
This is exactly what specialist assessment is for. You do not need any prior knowledge of watches or jewellery to use Fair Vintage. Photograph everything and submit — our specialists will identify the pieces and provide values. The written schedule you receive gives you everything you need to report to HMRC and to advise beneficiaries.
