Yes, in almost every case the deceased's home has to be valued for probate, because the property forms part of the estate that an executor reports before a grant is issued. What is not always required is a formal surveyor's valuation. For a modest estate well below the inheritance tax thresholds, two or three written estate agent estimates, averaged, are commonly accepted.
The distinction matters because the property value drives the probate application fee, decides whether inheritance tax is due, and sets the figure HMRC may later check. This guide explains when an estate agent estimate is enough and when a formal RICS valuation is the safer route, under the law of England and Wales. Figures are current as at August 2026 and are subject to change.
Do you need a house valuation for probate? The short answer
To apply for probate, an executor or administrator has to value everything the person owned, including their home, at its open market value on the date of death (gov.uk, valuing property and belongings, as at August 2026, subject to change). So a valuation of some kind is needed. What is optional is the format:
- Estate agent estimates. Often used where the estate is clearly below the inheritance tax threshold and the property is a standard home with recent comparable sales nearby.
- Formal RICS "Red Book" valuation. A written valuation from a chartered surveyor, generally used where the estate is close to or above the inheritance tax threshold, where tax is payable, or where the property is unusual, tenanted, or hard to compare.
Neither route is a legal guarantee against a later query. The value recorded is a figure the executor is responsible for, and HMRC's Valuation Office Agency can review it.
Formal valuation vs estate agent estimate
The two approaches differ in cost, weight and how well they hold up if the figure is questioned. The table below sets out the practical differences.
| Feature | Estate agent estimate | RICS formal valuation |
|---|---|---|
| Typical use | Smaller estates well below the tax threshold | Estates near or above the threshold, or where tax is due |
| Cost | Often free | A professional fee, agreed in advance |
| Written to a set standard | No fixed standard | Yes, the RICS Red Book valuation standards |
| Weight with HMRC | May be challenged if it looks low | Less likely to be questioned |
| Good practice | Obtain two or three and take an average | A single valuation from a qualified surveyor |

What "open market value" means, and the date that counts
For probate and inheritance tax, a property is valued at the price it would reasonably fetch if sold on the open market on the date the person died, not the date of the application or the eventual sale (gov.uk, as at August 2026, subject to change). A rising or falling market after the death does not change the probate figure, although it can affect capital gains tax on a later sale, covered below. Where a property is owned jointly, only the deceased's share is counted, and a discount is sometimes applied to a part share, which is one point where a professional valuation earns its cost.
When a formal valuation tends to be worth it
An estate agent estimate can be perfectly adequate. A formal RICS valuation is more commonly chosen in these situations:
- The estate is close to or above the nil-rate band of £325,000, so the property value could tip it into inheritance tax (gov.uk, inheritance tax, as at August 2026, subject to change).
- Inheritance tax is payable, so the figure will be scrutinised.
- The property is unusual, has development potential, is tenanted, or has no recent comparable sales nearby.
- The beneficiaries do not all agree, or a share of the property is being valued.
Because an undervaluation can lead to a later tax bill, interest and possible penalties, and an overvaluation can mean paying more tax than necessary, an accurate figure protects the estate in both directions.
How the valuation feeds probate and inheritance tax
The property value is added to the rest of the estate, and the total decides which reporting route applies. For deaths on or after 1 January 2022 the old IHT205 form was withdrawn, and most estates that owe no tax now report their value within the probate application itself as an "excepted estate" (gov.uk, excepted estates, as at August 2026, subject to change).
| Situation | What it usually means |
|---|---|
| Gross estate under £325,000 | Commonly an excepted estate; value reported within the probate application |
| Gross estate under £3,000,000, all passing to a spouse, civil partner or charity | Commonly an excepted estate, subject to the detailed conditions |
| Inheritance tax is due | Full account on form IHT400, reported within 12 months of the death |

The standard inheritance tax rate is 40%, or 36% where at least 10% of the net estate passes to charity, and the nil-rate band and residence nil-rate band (up to £175,000) are frozen until 5 April 2031 (gov.uk), subject to change.

Cost and timescales
The property valuation is one cost among several in administering an estate. The court fee is fixed, while the valuation cost depends on the route chosen.
| Item | Cost (England and Wales) |
|---|---|
| Estate agent estimate | Often free |
| RICS formal valuation | A professional fee, agreed with the surveyor in advance |
| Probate application fee (estate over £5,000) | £526 |
| Estate valued at £5,000 or less | No fee |
| Extra copies of the grant (ordered with the application) | £2 each |
Court fees source: gov.uk, applying for probate: fees, as at August 2026, subject to change. The application fee rose to £526 on 13 July 2026.
What if the house sells for more or less than the valuation?
The probate value becomes the baseline for capital gains tax if the property is later sold by the estate or a beneficiary. A sale above the date-of-death value may produce a chargeable gain; a sale below it may create a loss to consider (gov.uk, capital gains tax, as at August 2026, subject to change). This is a further reason a realistic figure at the outset can matter, because a value set too low to save inheritance tax can create a larger capital gains bill later. Where inheritance tax has been paid, separate rules can allow the value to be adjusted if a property sells for less within a set period after death, which is a point many people take advice on.
Key facts at a glance
- The home must be valued for probate, at its open market value on the date of death (gov.uk, as at August 2026, subject to change).
- An estate agent estimate can be enough for a smaller estate; a RICS valuation is common where tax is due or the estate is near the threshold.
- The nil-rate band is £325,000 and the residence nil-rate band is up to £175,000, frozen until 5 April 2031 (gov.uk, as at August 2026, subject to change).
- The probate application fee is £526 for an estate over £5,000, and there is no fee at £5,000 or less (gov.uk, as at August 2026, subject to change).
- Scotland and Northern Ireland differ, see below.
Scotland and Northern Ireland
This guide describes England and Wales. Scotland uses "confirmation" rather than a grant of probate, with its own procedure and fees, and Northern Ireland has a separate but broadly similar system to England and Wales. Where an estate includes property in more than one UK nation, the rules of each apply, and it can be worth taking advice in the relevant jurisdiction.
Frequently asked questions
Do I need a professional house valuation for probate?
Not always. A professional RICS valuation is commonly used where inheritance tax is payable or the estate is close to the £325,000 nil-rate band (gov.uk, as at August 2026, subject to change). For a smaller estate with a standard home, two or three estate agent estimates, averaged, are often accepted. The value must still reflect the open market value at the date of death.
Can I use an estate agent valuation for probate?
Yes, estate agent valuations are widely used, particularly for estates well below the inheritance tax threshold. Obtaining more than one and taking an average is common practice, as it gives a fairer figure than a single estimate. Where the figure could affect whether tax is due, a formal valuation carries more weight if HMRC reviews it.
How do you value a house for probate?
The property is valued at the price it would reasonably have fetched on the open market on the date of death, either through estate agent estimates or a RICS chartered surveyor (gov.uk, as at August 2026, subject to change). The figure is then added to the rest of the estate to work out the probate application and any inheritance tax.
What date is used to value the house for probate?
The date of death. Movements in the property market after that date do not change the probate value, although they can affect capital gains tax if the property is sold later for more or less than the date-of-death figure (gov.uk, as at August 2026, subject to change).
Does the house still need valuing if no inheritance tax is due?
Yes. Even where an estate is an excepted estate with no tax to pay, its value, including the home, is reported within the probate application (gov.uk, excepted estates, as at August 2026, subject to change). The value also sets the probate application fee, which is £526 for an estate over £5,000 (gov.uk, as at August 2026, subject to change).
What happens if the house sells for more than the probate value?
The date-of-death value is the baseline for capital gains tax, so a sale above that figure can produce a chargeable gain, while a sale below it may create a loss to consider (gov.uk, as at August 2026, subject to change). Where inheritance tax was paid, separate rules can allow a downward adjustment if a property sells for less within a set period after death, which is often a point for professional advice.
