A probate property valuation is an assessment of a property's open market value at the date the owner died. It is needed to work out the value of the estate for inheritance tax and to apply for a grant of probate.
The valuation is not what the property might sell for months later, and it is not the price a quick sale might accept. It is the figure a willing buyer and a willing seller would agree at the date of death (HMRC Inheritance Tax Manual IHTM09703, as at August 2026, subject to change). This guide explains who values the property, when an estate agent appraisal is enough, when a formal surveyor's valuation is worth having, and how the figure is reported. It describes the law of England and Wales.
What is a probate property valuation?
When someone dies, the person dealing with the estate (the personal representative) has to list everything the deceased owned and find or estimate the value of each asset on the date of death. For most estates the home is the largest single item, so its value often drives the whole process. The required basis is open market value, defined as the price the property might reasonably be expected to fetch if sold in the open market at that time (gov.uk, valuing an estate, as at August 2026, subject to change). The costs of selling, such as agent and legal fees, are not deducted from that value.
Why the date-of-death value matters
The property figure feeds three separate things, so accuracy matters.
- Inheritance tax. The value is added to the rest of the estate to work out whether inheritance tax is due. The nil-rate band is £325,000 and the residence nil-rate band is up to £175,000 where a home passes to direct descendants (gov.uk/inheritance-tax, as at August 2026, subject to change). These thresholds are frozen until 5 April 2031, an extension announced at Budget 2025 and legislated in Finance Bill 2025-26 (gov.uk, Inheritance Tax thresholds, as at August 2026, subject to change).
- The probate application. The estate value determines which application route applies and what has to be reported to HM Courts and Tribunals Service.
- Future capital gains tax. The date-of-death value becomes the base cost for anyone who later inherits and sells the property. If the property rises in value before it is sold, capital gains tax may be due on the increase above the probate value (gov.uk, tax on things you inherit, as at August 2026, subject to change).
A figure set too low can lead to an HMRC enquiry and a possible penalty. A figure set too high can mean an estate pays more inheritance tax than it needs to. A defensible, well-evidenced valuation reduces the risk of both.
How to value a property for probate
There are three common routes, and they suit different estates.
| Route | What it involves | Best suited to |
|---|---|---|
| Estate agent appraisal | One or more local agents give a written market appraisal of the date-of-death value. Often free. | Estates comfortably below the inheritance tax thresholds, where no tax is at stake. |
| RICS "Red Book" valuation | A chartered surveyor prepares a formal written valuation to a recognised professional standard. | Taxable estates, higher-value or unusual properties, and cases likely to be scrutinised. |
| Own research | Comparing recent sold prices for similar nearby properties using Land Registry and portal data. | Supporting evidence alongside the above, rather than a standalone figure for a taxable estate. |
Where inheritance tax is likely to be due, HMRC may refer the valuation to the Valuation Office Agency, whose District Valuer can challenge a figure that is not properly supported (gov.uk, VOA Inheritance Tax Manual, as at August 2026, subject to change). A formal valuation gives the personal representative a professional figure to stand behind.
Do you need a formal valuation or an estimate?
As a general guide, the closer the estate is to a tax threshold, the stronger the case for a formal RICS valuation. Where the whole estate is clearly well below the available nil-rate bands and no tax can arise, a written estate agent appraisal is commonly accepted. Where inheritance tax is in point, a formal valuation carries more weight, provides a documented basis for the figure, and can reduce the risk of a later dispute. Our related guide to what probate is and how it works sets out where the valuation sits in the wider process.
Valuing jointly owned property
How a shared property is treated depends on how it was owned. Two people can hold a home as joint tenants or as tenants in common, and the difference affects both what passes and how the share is valued.
- Joint tenants. The deceased's interest passes automatically to the surviving owner by survivorship, outside the will. The value of the deceased's share is still included in the estate for inheritance tax.
- Tenants in common. The deceased owned a distinct share (often half) that passes under the will or the intestacy rules. Only that share is valued and included.
When only a part share in a property is being valued, HMRC may accept that a share is worth less than a simple fraction of the whole, because a share on its own is harder to sell (gov.uk, VOA Inheritance Tax Manual, undivided shares, as at August 2026, subject to change). A surveyor can advise on the appropriate treatment. If you are not sure how a property was held, the register held by HM Land Registry will show the ownership.
Reporting the value to HMRC
For deaths on or after 1 January 2022, many non-taxpaying estates are "excepted" and do not need a full inheritance tax account. Instead the personal representative reports estate values directly on the probate application (gov.uk, report an excepted estate, as at August 2026, subject to change). Where the estate is taxable, or does not qualify as excepted, form IHT400 is used.
| Situation | What is reported |
|---|---|
| Low value excepted estate (gross value below the £325,000 nil-rate band) | Values reported on the probate application (PA1P or PA1A), no IHT400. |
| Exempt excepted estate (gross value up to £3,000,000, passing to a spouse, civil partner or charity so no tax is due) | Values reported on the probate application, no IHT400. |
| Taxable estate, or not an excepted estate | Full account on form IHT400, with any property valuation supporting the figure. |

Costs and timescales
| Item | Typical position |
|---|---|
| Estate agent appraisal | Often provided free of charge. |
| RICS "Red Book" valuation | A professional fee, quoted by the surveyor for the property. Confirm the cost before instructing. |
| Probate application fee (estate over £5,000) | £526 (gov.uk, as at August 2026, subject to change). |
| Probate application fee (estate £5,000 or less) | No fee (gov.uk, as at August 2026, subject to change). |
| Extra copies of the grant | £2 each when ordered with the application (gov.uk, as at August 2026, subject to change). |
An estate agent appraisal can be arranged within days. A formal surveyor's valuation usually follows an inspection and a written report, so it takes longer to obtain. Because the valuation must reflect the date of death, it is generally sensible to gather the evidence early, even where the property will be sold much later.
- Basis of valuation: open market value at the date of death (HMRC IHTM09703).
- Nil-rate band £325,000; residence nil-rate band up to £175,000 where a home passes to direct descendants (gov.uk).
- Excepted estate reporting for many non-taxable estates since 1 January 2022; otherwise form IHT400 (gov.uk).
- Probate application fee £526 for estates over £5,000 (gov.uk).
- The date-of-death value becomes the base cost for any later capital gains tax (gov.uk).
Frequently asked questions
How much does a probate property valuation cost?
An estate agent market appraisal is often free, while a formal RICS valuation carries a professional fee that the surveyor quotes for the specific property. The separate probate application fee is £526 for estates over £5,000, with no fee for estates of £5,000 or less (gov.uk, as at August 2026, subject to change). It is worth confirming any valuation fee in writing before instructing.
Do I need a RICS valuation for probate?
Not always. Where the estate is clearly below the inheritance tax thresholds and no tax can arise, a written estate agent appraisal is commonly accepted. Where inheritance tax is likely to be due, a formal RICS valuation gives a professional figure that is easier to support if HMRC or the Valuation Office Agency looks at it (gov.uk, as at August 2026, subject to change).
Can I use an estate agent valuation for probate?
Yes, a written estate agent appraisal of the open market value at the date of death is often used, particularly for estates where no inheritance tax is due. Asking two or three agents and keeping the written figures gives a stronger evidence base. For taxable estates, a formal valuation generally carries more weight.
Is the probate value the same as the sale price?
Not necessarily. The probate value is the open market value at the date of death, while the sale price is what the property later achieves, which may differ as the market moves. If a property sells for more than the probate value, capital gains tax may apply to the increase; if it sells for less within a set period, personal representatives may in some cases claim relief (gov.uk, as at August 2026, subject to change).
What happens if HMRC disputes the property valuation?
Where inheritance tax is in point, HMRC can ask the Valuation Office Agency to review a property figure, and its District Valuer may propose a different value (gov.uk, as at August 2026, subject to change). A valuation supported by comparable evidence or a formal surveyor's report is easier to defend. Additional tax and, in some cases, a penalty can follow an under-valuation that is not properly evidenced.
Does the value include the cost of selling the property?
No. The open market value used for probate and inheritance tax does not deduct the costs of sale, such as estate agent or legal fees (gov.uk, as at August 2026, subject to change). Those costs sit outside the valuation figure.
