Inheritance / Probate Valuations
"We’re here to bring clarity and compassion to life’s most difficult transitions, helping families navigate inheritance with confidence and fairness."
- Dan Knowles FRICS, Managing Director and RICS Registered Valuer

An inheritance tax valuation — also called a probate valuation — establishes a property's open market value as at the date of death, the figure HMRC uses to assess inheritance tax. Tax is charged at 40% above the £325,000 nil-rate band, with up to £175,000 more where a main home passes to direct descendants — both frozen until April 2031. As RICS Registered Valuers, we provide formal "Red Book" reports accepted by HMRC.
The numbers
What are the inheritance tax thresholds in 2026?
The allowances that decide whether — and how much — inheritance tax an estate pays.
Per person, passed on tax-free.
Where a main home passes to direct descendants.
An individual, up to a married couple or civil partners.
Charged on the estate above the available bands.
Both bands are frozen until April 2031. As property values rise, more estates are drawn into inheritance tax each year — which is why an accurate valuation matters.
How we value
How do we value a property for inheritance tax?
We assess open market value as at the date of death under section 160 of the Inheritance Tax Act 1984 — and we reflect the real property, not an assumption.
Comparable evidence
Completed sales of similar local properties, plus our detailed knowledge of the market, so the figure is properly supported.
True condition
If the condition is poor, the value — and therefore the tax — should be lower. We reflect the property as it actually was.
Tenancies, shares & circumstances
If the property was let on the date of death, or owned as a share rather than outright, the value may — depending on the circumstances — be lower still. A tenancy in common share, for example, can sometimes carry a discount. We capture the true position.

Inspection
An RICS Registered Valuer inspects the property, so the valuation rests on what's really there.
Your report
A clear, HMRC-compliant Red Book valuation that explains exactly how we reached the figure — normally within about a week of inspection.
Ongoing support
Evidence ready to stand behind the figure if the Valuation Office Agency (VOA) ever queries it.
Could you be paying more inheritance tax than necessary?
Many estates over-pay because a valuation overlooks condition, a tenancy, or other circumstances that legitimately reduce value. Our reports reflect the true position of the property — so you pay what's right, and no more, with a figure that stands up to HMRC scrutiny.

Good to know
Inheritance tax valuations: frequently asked questions
What is an inheritance tax (probate) valuation?
It is a professional assessment of a property's open market value as at the date of death, prepared to the standard in section 160 of the Inheritance Tax Act 1984 — broadly, the price the property might reasonably be expected to fetch on the open market at that date. Our reports are formal "Red Book" valuations, prepared to RICS Global Standards and accepted by HMRC.
Do you need a RICS valuation for probate?
For any estate at or near the inheritance tax threshold, or where the value may be questioned, a formal Red Book valuation by a RICS Registered Valuer is strongly advisable. An estate agent's appraisal carries less weight with HMRC and can be challenged by the Valuation Office Agency (VOA), which risks delays, further enquiries or additional tax.
How is a property valued for inheritance tax?
We assess open market value at the date of death using completed comparable sales and detailed local knowledge, and we reflect the property's real condition and circumstances. Poor condition, or a tenancy in place at the date of death, can legitimately reduce the value — and therefore the tax.
How much can you pass on before inheritance tax?
The nil-rate band is £325,000 per person, with a residence nil-rate band of up to £175,000 where a main home passes to direct descendants — a combined £500,000, or up to £1 million for a married couple or civil partners. Both are frozen until April 2031, and inheritance tax is charged at 40% on the value above the available bands.
Can HMRC challenge a probate property valuation?
Yes. HMRC can refer a valuation to the Valuation Office Agency (VOA), which may dispute the figure. A properly evidenced Red Book valuation by a RICS Registered Valuer, backed by completed comparable sales, substantially reduces the risk of a successful challenge.
What date is used for the valuation?
The valuation date is the date of death. Open market value is assessed as at that date — not the date the property is inspected or eventually sold — which is why a retrospective valuation by a qualified surveyor is often needed.
Can a discount apply if the property was rented out at the date of death?
In some circumstances, yes. Where a property was let on the date of death — normally at arm's length, to an unconnected tenant rather than to family or friends — a buyer would take it subject to that tenancy, which can reduce its open market value and therefore the inheritance tax. Whether a discount applies, and how much, depends on the type of tenancy and the wider circumstances.
Does it matter whether the property was owned as joint tenants or tenants in common?
It can. Most couples own as joint tenants, where the surviving owner automatically inherits 100% of the property. Where owners instead hold distinct shares as tenants in common, only the deceased's share forms part of the estate — and a share in a property can, in some circumstances, be valued at a discount to its arithmetical proportion, which reduces the inheritance tax. The right approach depends on the ownership and who else occupies the property.
How much does a probate valuation cost?
Our inheritance tax (probate) valuations start from £500+VAT for the most straightforward properties. The fee reflects a full inspection by an RICS Registered Valuer and a properly evidenced Red Book report built to stand up to HMRC scrutiny. We'll give you a clear, fixed price when you request a quote.
How quickly can you provide the report?
We're normally able to provide your report within about a week of inspection, and can often work to tighter deadlines where an estate is under time pressure. We'll confirm timing when you instruct us.
