Probate Valuations: A Practical Guide for Executors

Losing someone close to you is hard enough. Having to navigate the legal and financial complexities of estate administration at the same time makes it even harder. If the estate includes residential property — and in London, it very often does — you'll need a formal RICS valuation for probate purposes.

At Battersea Surveyors, we handle probate valuations regularly. We understand the need for sensitivity, speed, and accuracy. This guide explains everything executors need to know.

What is a Probate Valuation?

A probate valuation is a formal, written assessment of a property's market value at the date of death. It's required by HMRC as part of the inheritance tax (IHT) assessment on the deceased's estate. Without it, you cannot obtain Grant of Probate — the legal authority to administer the estate.

The valuation must be carried out by a qualified professional. While technically any qualified valuer can prepare a probate valuation, HMRC strongly recommends and in practice expects a RICS Red Book valuation from a RICS Registered Valuer. This protects both the executor and the beneficiaries from challenge.

When is a Probate Valuation Required?

You'll need a probate valuation when:

• The estate is large enough to potentially attract inheritance tax (currently estates over £325,000 — or £500,000 with the residence nil-rate band)
• You're applying for a Grant of Probate and the estate includes residential or commercial property
• The property is to be sold as part of estate administration
• There is any dispute between beneficiaries about the property's value

Even if the estate falls below the IHT threshold, a formal valuation is useful for estate accounting purposes and can protect executors from future challenges.

Inheritance Tax and Property in London

The standard IHT threshold (the "nil-rate band") is £325,000 per person. There's an additional "residence nil-rate band" of up to £175,000 where the main residence passes to direct descendants. A surviving spouse can inherit the deceased's unused allowances, potentially providing a combined threshold of £1 million.

Given that the average Battersea property is worth well in excess of £500,000, many estates in London will exceed these thresholds. Even where no IHT is payable, HMRC may scrutinise the probate valuation — particularly if the property is subsequently sold at a significantly different price.

"I always advise executors to instruct a RICS surveyor as soon as possible after the death. The closer the valuation date to the date of death, the more straightforward the evidence. Properties can go up or down in value — and if HMRC questions a valuation months after the event, you need robust evidence."— Sarah Mitchell, Surveyor & Valuer

How Our Probate Valuation Works

1. Initial contact: You contact us with details of the property. We provide a fixed fee quote — usually within a few hours.
2. Inspection: One of our RICS Registered Valuers visits the property. We'll need access arranged — either through a key holder, solicitor, or agent. We work sensitively and can accommodate families clearing the property.
3. Market research: We research comparable sales in the area around the date of death to establish an accurate market value.
4. Valuation report: We produce a formal RICS Red Book valuation report, typically within 3–5 working days.
5. HMRC submission: The executor or solicitor uses our report to complete the inheritance tax return (IHT400 or IHT205).

Retrospective Valuations

Sometimes there's a delay between the date of death and when the probate valuation is instructed — perhaps because the family needed time, or the estate is complex. In these cases, we carry out a retrospective valuation, assessing the value of the property as it was on the date of death, using historical market data from that period.

This is a specialist skill. Not every surveyor is experienced in retrospective valuation, and it's important to choose one who is. At Battersea Surveyors, our team regularly carries out retrospective valuations going back several years.

What if HMRC Disputes the Valuation?

HMRC's Shares and Assets Valuation team reviews all property valuations submitted for probate. If they believe the value is too low, they will raise a "district valuer" check and may propose a higher figure.

A RICS Red Book valuation from a Registered Valuer carries significant weight in these discussions. Our reports are prepared to withstand HMRC challenge — and where a dispute arises, we can provide additional supporting evidence or appear as expert witnesses if necessary.
