House Valuation for Probate
When someone dies, their property usually needs to be valued as part of settling the estate. Getting that figure right matters, because it feeds directly into the probate application and any inheritance tax due.
A house valuation for probate must reflect the property's open-market value on the date of death — the price it would realistically have sold for at that time. For a modest estate a well-evidenced estimate can be enough, but where inheritance tax is in play, HMRC expects a formal RICS 'Red Book' valuation from a qualified surveyor.

What a Probate Valuation Is For
Probate is the legal process of dealing with a deceased person's estate. Before the estate can be distributed, its total value has to be established — and for most estates the home is the largest single asset. The valuation figure is used to:
- Complete the probate application to the Probate Registry.
- Calculate any inheritance tax due to HMRC.
- Establish the base value for any future capital gains tax if the property is later sold for more.
Because it affects tax, HMRC can and does scrutinise property valuations, so an accurate, defensible figure protects the executors.
Who Can Value the Property
Two routes are common, and which you choose depends on the size and complexity of the estate.
Estate agents. For a straightforward estate well below the inheritance tax threshold, obtaining two or three written valuations from local estate agents and taking a considered average is often acceptable. It's free and quick, but the figures aren't independent.
RICS surveyors. Where inheritance tax is likely to be payable, or the estate is large or the property unusual, a formal valuation by a member of the Royal Institution of Chartered Surveyors (RICS) is strongly advised. A "Red Book" valuation is prepared to a professional standard, carries accountability, and is far more likely to withstand HMRC challenge. Our guide to the process of getting a house valued explains what a surveyor's inspection involves.
What HMRC Expects
HMRC looks for an honest, evidence-based open-market value as at the date of death — not a quick sale price, and not an inflated one. Under-valuing to reduce tax can lead to penalties if the property later sells for substantially more; over-valuing can needlessly increase the tax bill. A professional valuation supported by comparable sales is the safest position.
To sense-check any figure, executors can look at what similar homes nearby actually sold for around the relevant date. Our house prices pages and the free house value calculator both draw on Land Registry sold-price data, which is a useful starting point before commissioning a formal valuation.
Inheritance Tax in Brief
Inheritance tax may be due on estates above the available nil-rate band, with an additional residence nil-rate band potentially available when a home passes to direct descendants. These thresholds have been frozen, which means more estates are drawn into paying as property values rise. The rules are detailed and depend on individual circumstances, so always check the current allowances and rates on GOV.UK or with a solicitor.
Planning ahead can reduce a future bill. Related reading includes the inheritance tax 7-year rule on lifetime gifts, and whether you can give your house to your children.
Practical Steps for Executors
- Establish the date of death — the valuation is fixed to that day.
- Gather evidence: comparable sold prices, the property's condition, and any tenancy or shared ownership.
- Decide between agent estimates and a RICS valuation based on the estate's size.
- Keep all documentation; HMRC may ask to see how the figure was reached.
- Make sure the original will is located — our guide on where to store a will may help if it isn't immediately to hand.
Selling After Probate
If the property is later sold for significantly more than the probate value, the difference may be liable to capital gains tax for the estate or beneficiaries. This is another reason to value accurately at the outset rather than pitching low.
Do I need a RICS valuation for every probate?
No. For small, simple estates comfortably below the tax thresholds, estate agent valuations are often accepted. A RICS valuation becomes important where inheritance tax is due or the figure could be challenged.
What date should the valuation reflect?
The open-market value on the date of death, not the date you apply for probate or the date of sale.
Can I use an online estimate for probate?
An online estimate is a helpful cross-check but is not a formal valuation. For anything involving tax, back it with agent valuations or a RICS report.
