Why getting the valuation right matters

When someone dies, the value of their property at the date of death must be reported to HMRC as part of the probate application. This probate valuation is used to calculate any inheritance tax owed by the estate. It also becomes the base cost for capital gains tax if the property is later sold for a different amount.

Getting it wrong can be costly

If the valuation is too high, the estate may overpay inheritance tax. If too low, HMRC may challenge it - leading to additional tax, interest, and penalties. The goal is an honest, accurate figure.

This can feel like a lot of pressure during an already difficult time. The good news is that there are clear guidelines on how to approach it, and you do not need to get it perfect to the pound. HMRC understands that property valuation is not an exact science - they simply expect a reasonable and well-supported figure.

Your Options

Three types of property valuation for probate

Estate agent appraisal

Free

Ask two or three local estate agents to provide a market appraisal. This is the same process used when valuing a property for sale. It gives you a reasonable estimate, but agent appraisals are opinions rather than formal valuations - and agents may overvalue to win instructions.

+ Quick and free- Not formal evidence

RICS surveyor valuation

£250-£750

A formal Red Book valuation by a qualified RICS surveyor. This carries significantly more weight than an estate agent's opinion and provides a detailed report. Strongly recommended for higher-value properties or where inheritance tax is payable.

+ Strong HMRC evidence- Cost varies by property

HMRC's own valuation check

N/A

HMRC's District Valuer can check probate valuations using Land Registry price data and comparable sales. If they believe your figure is too low, they will contact you. Having a professional valuation to support your figure makes challenges easier to handle.

+ Independent check- Can increase tax bill

Be Prepared

What HMRC looks for

HMRC reviews probate valuations as a matter of course, particularly for estates that are close to or above the inheritance tax threshold. They compare the reported value against their own data.

If HMRC challenges your valuation, they will write to the executor asking for supporting evidence. You can provide surveyor reports, photographs, or comparable sale evidence. If you cannot agree, the matter can be referred to the Lands Tribunal.

Best protection

Document the property's condition with photographs, keep records of factors affecting value, and obtain professional advice where the value is significant.

Red flags that trigger HMRC scrutiny

Value significantly below comparable properties

HMRC compares against Land Registry records and local sale prices

Property sells for much more than probate value

A large gap suggests the original valuation may have been too low

Inconsistencies in property description

The description doesn't match the reported value or known characteristics

Estate marginally below IHT threshold

Valuations that conveniently land just under the tax-free amount

Key Difference

Probate value vs market value

These two values are related but serve different purposes and can be different amounts. Understanding the distinction is essential for executors.

Probate value

The estimated open market value at the date of death. Reported to HMRC and used to calculate inheritance tax. Reflects the property's condition and market at that specific moment.

Used for: Inheritance Tax

Market value

What the property could sell for when it actually goes on the market. This might be weeks or months later, during which prices may change and the property's condition may deteriorate.

Used for: Capital Gains Tax

What happens when you sell

Sell for MORE than probate value

The difference is treated as a capital gain. CGT may be payable at 18% (basic rate) or 24% (higher rate). HMRC may also question whether the original probate valuation was too low.

Potential CGT liability

Sell for LESS than probate value

If sold within 4 years, the executor can claim under Section 191 IHTA 1984 to substitute the lower sale price as probate value, potentially getting an IHT refund from HMRC.

Step by Step

The probate valuation process

Gather property information

Day 1

Collect details about the property: size, condition, any known issues, recent improvements, and comparable properties nearby. Take photographs documenting the current condition.

Get estate agent appraisals

Week 1

Request free appraisals from 2-3 local estate agents. Ask them to value the property as at the date of death, considering its condition at that time - not what it could be worth after renovations.

Consider a RICS valuation

Week 1-2

If the estate is likely to owe inheritance tax or the property is high-value, commission a formal RICS Red Book valuation. This provides the strongest evidence if HMRC queries your figure.

Report the value to HMRC

With probate application

Include the probate valuation in your IHT forms as part of the probate application. Keep all supporting evidence, photographs, and valuations for your records.

Respond to any HMRC queries

If applicable

If HMRC challenges the valuation, provide your supporting evidence. A well-documented valuation from the outset makes this process much smoother.

Common questions about probate property valuations

HMRC does not require a formal RICS valuation for probate in most cases. A reasonable estimate of the property's open market value at the date of death is usually sufficient. However, for higher-value properties or where inheritance tax is payable, a professional RICS valuation can provide stronger evidence of value and protect you if HMRC decides to challenge your figure. If the property is worth more than the inheritance tax threshold, spending a few hundred pounds on a proper valuation can save you significant money and worry later.

You need to estimate the open market value of the property at the date of death - not what you hope to sell it for or what it might be worth after improvements. You can get free estate agent appraisals, commission a RICS surveyor's valuation, or use a combination of both. Consider the property's condition at the date of death, comparable sales in the area, and any factors that might affect value such as structural issues, short leases, or access problems. The figure should be honest and defensible.

Estate agent appraisals are usually free, though they are opinions rather than formal valuations. A RICS Red Book valuation from a chartered surveyor typically costs between 250 and 750 pounds depending on the property type, size and location. For more complex or higher-value properties, costs can be higher. While the expense may feel unnecessary, a professional valuation provides much stronger evidence if HMRC queries your probate figure and can ultimately save money.

Probate value is the estimated open market value of the property at the date of death. Market value is what the property could actually sell for at the time it goes on the market, which might be weeks or months later. These figures can differ because property prices change over time, and the condition of a vacant property may deteriorate. The probate value is used to calculate any inheritance tax owed, while the actual sale price determines any capital gains tax liability on the difference between the two.

If you sell the property for more than the probate value, capital gains tax (CGT) may be payable on the difference. The probate value becomes the base cost for CGT purposes. If the gain is substantial, it may also prompt HMRC to question whether the original probate valuation was too low. Executors should aim for an accurate probate valuation from the outset to avoid complications. The annual CGT allowance and any available reliefs may reduce or eliminate any tax owed.

Yes, HMRC can and does challenge probate valuations that it considers too low. HMRC has its own valuation office and access to property transaction data. If they believe a property has been undervalued, they can open an enquiry and request evidence supporting your valuation. If they are not satisfied, they can substitute their own valuation and charge additional inheritance tax plus interest. Having a well-documented, professional valuation significantly reduces the risk of a successful challenge.
