Accurate property valuation is a cornerstone of the probate process in England and Wales. It directly affects Inheritance Tax (IHT) calculations, ensures a fair distribution among beneficiaries, and sets the base value for future Capital Gains Tax (CGT) if the property is later sold. Getting the value right is not just a formality—it can prevent costly disputes with HMRC and between family members, and helps executors fulfil their legal duties.

Why Accurate Valuation Matters

A correct valuation determines the amount of IHT payable. If the property is undervalued, HMRC may challenge the figure, leading to penalties and interest. Overvaluation, on the other hand, could result in unnecessary tax being paid. Accurate valuation also helps avoid disagreements between beneficiaries, especially where one person wishes to buy out others or where the property is to be sold and proceeds divided. It provides a reliable starting point for any future property disposals, as the probate value becomes the “base cost” for CGT calculations.

Methods of Property Valuation

There are several approaches to valuing property for probate, each with its own strengths and limitations:

• Professional Valuation by a RICS Surveyor: This is the gold standard, especially for higher-value or complex properties. A RICS (Royal Institution of Chartered Surveyors) qualified surveyor provides a formal, detailed assessment, often referred to as a “Red Book” valuation. This is the most robust evidence if HMRC queries the value.

• Estate Agent Appraisals: These can offer a market-based estimate and are often used for straightforward properties. It’s common to obtain two or three appraisals and take an average, but these are less formal than a RICS valuation.

• Desktop Valuations: Online tools and automated valuation models can be suitable for simple, low-value properties, but may not reflect unique features or local market nuances.

• Drive-by Valuations: A surveyor assesses the property from the outside, which can be useful if access is difficult, but may not capture internal condition or issues.

Factors Affecting Value

Several factors influence a property’s value for probate:

• Location: Properties in sought-after areas or with good transport links tend to command higher prices.

• Condition: Well-maintained homes are generally worth more, while those needing repairs or modernisation may be valued lower.

• Market Trends: The value should reflect the open market value at the date of death, not at the time of sale. Sudden market changes can create discrepancies.

• Unique Features: Extensions, large gardens, or development potential can increase value, while restrictive covenants or short lease terms may reduce it.

• Joint Ownership: Only the deceased’s share is included in the estate, but the valuation must reflect the open market value of that share, which can be complex if the property is jointly owned with someone who is not a spouse or civil partner.

Benefits of Professional Valuation

Using a qualified valuer, especially for high-value or unusual properties, reduces the risk of HMRC challenges. A detailed report provides a clear audit trail and can be invaluable if there are disputes among beneficiaries or if HMRC queries the declared value. It also gives executors confidence that they have fulfilled their legal obligations.

Valuation Costs

Costs vary depending on the method and complexity:

• Desktop valuations: £200–£500

• Drive-by valuations: £300–£800

• Full RICS valuations: £500–£1,500 or more for unique or complex properties

While it may be tempting to save money with a cheaper option, the cost of a professional valuation is often justified by the peace of mind and protection it provides.

Common Valuation Issues

• Probate value vs. sale price: The value at the date of death may differ from the eventual sale price, especially if the market moves. HMRC is interested in the value at the date of death, not the sale proceeds.

• Development potential: If the property has potential for redevelopment, this should be reflected in the valuation, even if no planning permission has been obtained.

• Leasehold complications: Short leases or onerous terms can significantly affect value and should be considered carefully.

Reducing Valuation Disputes

For high-value or unusual properties, consider obtaining multiple valuations and keep detailed records of how the value was determined. If HMRC challenges the valuation, be prepared to negotiate and provide supporting evidence, such as comparable sales or a formal surveyor’s report. Open communication with beneficiaries about how the value was reached can also help prevent misunderstandings.

Final Thoughts

Professional property valuation is not just a box-ticking exercise—it’s a vital step in protecting executors and beneficiaries, ensuring compliance, and laying the groundwork for smooth estate administration.
