RICS House Valuation for Probate
When an estate is subject to Inheritance Tax, executors face a strict legal requirement: they must provide HM Revenue & Customs (HMRC) with an exact, evidence-based figure of the deceased’s property value on the day they died. This specialised assessment is known as a house valuation for probate.
Unlike a free estate agent appraisal meant to market a property today, a probate valuation is a formal, retrospective calculation conducted by a RICS-qualified surveyor using the Red Book global standards. This crucial first step not only determines your immediate tax liabilities but also establishes the official baseline for any future Capital Gains Tax if the property is later sold.
If you guess the valuation, HMRC has sophisticated systems to flag house prices that aren't supported by robust market evidence, which can lead to lengthy investigations and financial penalties. In this article, we explain the exact process used by RICS surveyors to value a probate property, the legal risks of getting it wrong, and the costs of securing a formal RICS valuation.

- Date of death value: A probate valuation determines the exact open-market value of a property on the date the owner died, not its current value today.
- When it is legally required: You must obtain a professional house valuation if there is Inheritance Tax (IHT) to pay on the estate.
- Capital Gains & Refunds: If the property later sells for more than this probate valuation, you may owe Capital Gains Tax (CGT) on the uplift. If it sells for less within four years, you can claim an IHT refund.
- When it is NOT required: You do not need a professional valuation if the property is left to a surviving spouse or civil partner, or if the total estate value is clearly below the £325,000 threshold.

Will or no will (intestacy)?
If a valid will exists, the named executor(s) usually initiate the probate process. The assets, including any property, are then distributed according to the exact instructions in the will.
If there is no will, the closest next of kin must step forward to become the administrator. The estate's assets are then strictly distributed according to the government's intestacy rules, which dictate who inherits based on their relationship to the deceased.
The tax risks of selling
Getting the initial probate valuation right is critical for tax purposes. If you later sell the inherited property for more than its official probate value, you may be liable to pay Capital Gains Tax (CGT) on the profit. Conversely, if you sell the property for less than the probate value, you could be eligible to claim an Inheritance Tax refund from HMRC (known as 'loss on sale relief'). However, this refund can only be claimed if the property is sold within four years of the date of death. Find out more in our guide on how to sell a probate property.
Is a RICS probate valuation different from a normal valuation?
Yes. A probate valuation of a property is fundamentally different from a normal property valuation because it must accurately determine what the property was worth on the exact date of death, rather than its current open-market value today.
To do this, a RICS-accredited surveyor will conduct a site visit to assess the property's general condition. They will then research historical data to find comparable properties (in a similar condition) that sold around the date of the owner's death. This provides the strict, evidence-based valuation required by HMRC.
Because executors and administrators need this figure to calculate potential Inheritance Tax, they should ideally instruct a surveyor as soon as possible. However, due to funeral arrangements and the sudden burden of estate administration, valuations are frequently instructed 3 to 6 months after the death.
What is the difference between a market appraisal and a valuation?
An estate agent's market appraisal (usually offered for free) provides a rough estimate designed to win your business and list the property for sale. It is not considered an official legal valuation.
A RICS surveyor's valuation, though it carries a cost, is an independent, evidence-based report that holds significant legal weight. It is the standard expected by HMRC, particularly for complex estates or high-value properties.
HMRC's District Valuer Services (DVS) are responsible for scrutinising probate property valuations. If HMRC believes a valuation has been artificially lowered to avoid Inheritance Tax, they will challenge it and can impose heavy financial penalties on the executors.

Do I need an official house valuation for probate purposes?
You will need to get a professional probate valuation for several key reasons:
- It is a mandatory requirement when applying for the Grant of Probate if the estate is taxable.
- It is required to accurately calculate if any Inheritance Tax (IHT) is owed to HMRC.
- It establishes the 'base cost' needed to work out if Capital Gains Tax (CGT) is payable when the property is eventually sold.
It is important to note that a probate valuation is not a defect survey. The surveyor conducts a site visit strictly to review the property's condition for valuation purposes; they will not actively hunt for hidden structural defects or damp. If the property is in significant disrepair and you are considering keeping it, you may wish to instruct an additional condition report, such as a Level 3 Home Survey.
When a valuation is not needed
There are certain situations where you do not need to pay for a professional RICS valuation for probate:
- The property is being left entirely to a surviving spouse or civil partner (which is legally exempt from IHT).
- The property is being passed entirely to a qualifying charity or community amateur sports club.
- The total value of the estate (including the property and all savings) clearly falls well below the £325,000 Inheritance Tax threshold.

Valuing a house for probate: Who can do it?
To ensure HMRC accepts the valuation without question, the professional you instruct should be a RICS-qualified valuer (not just a standard estate agent). Specifically, the surveyor must be:
- A RICS Registered Valuer (in addition to being a RICS-qualified surveyor).
- Competent and highly experienced in providing date-of-death probate valuations within the local property market.
- Fully indemnified to provide formal property valuations.
- Working in strict accordance with the Red Book RICS Valuation Professional Standards.
- Completely independent, unrelated to the deceased or the executors, and holding no financial interest in the property itself.
How do you value a house for probate?
Before instructing a surveyor, you first need a rough estimate of the entire estate's worth. This includes the property value, plus any money, savings, and other assets the deceased left behind.
You can use the online GOV.UK Inheritance Tax checker to see if tax is likely to be due. If it is, you will need to step up from a rough estimate and instruct a professional house valuation for probate.
Executors often face several challenges when trying to arrange this:
- Disputes between multiple executors or administrators on who should pay the upfront cost for the valuation.
- Struggling to find a RICS valuer who specifically undertakes probate work (as many RICS surveyors only do standard homebuyer surveys).
- The property being in a poor, dated, or neglected condition, making it difficult to establish a true open-market rate without professional insight.
The RICS probate valuation method
A RICS surveyor assesses the property's open-market value strictly as of the date of death. This involves a thorough visual inspection of the property's condition, followed by detailed desktop research into recent sales of similar properties in the immediate area at that specific time. They will also factor in the property's location, size, and potential for future development.
The surveyor will then produce a formal, detailed written report outlining their methodology, their comparable evidence, and their final calculated market value. This legally robust document is what you submit to HMRC to determine your Inheritance Tax liabilities and ensure a fair, transparent distribution of the deceased's estate.
