Expert commentary from Alexander Wilks at Batcheller Monkhouse Rural & Estate Management
Property markets do not move in straight lines, and right now, clients across residential, agricultural and commercial sectors are asking the same question: what is my property actually worth in a market like this? A Red Book valuation – the formal RICS standard for chartered surveyor reports – is the only reliable way to find out.
The Market Is Uncertain. Your Red Book Valuation Should Not Be.
As chartered valuers, our job is to give you a figure you can rely on, not one designed to win your instruction or tell you what you want to hear. Every valuation we produce is grounded in actual sales evidence: real transactions, comparable properties, verified market data.
That means we are always working from what has happened, not what might happen. We cannot tell you where the market will be in twelve months. What we can tell you is what the evidence says your property is worth today, explained clearly and backed by professional accountability.
Understanding the Red Book Standard – and When You Need One
The term comes up often, and it is worth understanding what it means.
The RICS Valuation Global Standards, universally known as the Red Book, set the professional framework for formal valuations carried out by chartered surveyors. A Red Book valuation is a structured, evidence-based report prepared to a defined standard. It is a very different document from an estate agent’s market appraisal, which carries no such professional obligation.
Red Book reports are required for lending purposes, tax planning, property disputes, and other formal proceedings. For a complex rural property, a farm or an estate, a Red Book report can run well over a hundred pages. It examines not just the physical property but planning history, condition, legal title, access, location factors and much more.
We hold an extensive database of comparable evidence dating back to 1980. For tax purposes, where valuations are frequently required at historical dates as well as current ones, that depth of records is essential.

Which Valuations Are We Seeing Most?
The bulk of our instructions come from private individuals requiring formal valuations for probate or capital gains tax purposes. Alongside that, we carry out a significant volume of valuations for bank lending, pension funds, matrimonial proceedings and development or property disputes.
As a firm, we value several hundred million pounds worth of property each year across residential, rural and commercial sectors. The range is wide, and the depth of local market knowledge we bring to each instruction is one of the things that distinguishes a BM valuation from a generic report.
Getting the Tax Position Right: Where It Really Matters
The value of a professional valuation is rarely more apparent than in a tax context, and two areas in particular illustrate why precision and expertise make a material difference.
Capital Gains Tax: Principal Private Residence Relief
A common misconception is that the amount of garden or grounds eligible for Principal Private Residence Relief is capped at 0.5 hectares. In practice, it is possible to justify a larger area, but doing so requires detailed historical research and robust comparable evidence.
In one recent instruction involving a large house sale, our team was able to demonstrate that a greater area of land fell within the permitted grounds, drawing on historical records of the property and extensive comparable sales data. Working alongside the client’s accountants, the outcome was a materially improved tax position.
Our valuers understand the tax rules governing capital gains in detail. That knowledge, combined with local market evidence, means we can identify reliefs that a less specialist valuer might miss.
Inheritance Tax: Agricultural Property Relief
Agricultural Property Relief remains one of the most significant but also most complex reliefs available to farming families. Available on farmhouses and agricultural land, it requires careful navigation of case law and HMRC guidance to apply correctly.
We advise on APR claims during the probate process, ensuring that the valuation and accompanying evidence give the claim the best possible foundation. We also advise farming families and their advisers on structuring ownership and business arrangements in advance, so that future claims comply with the rules and maximise available reliefs.
The changes to APR announced in the Autumn Budget have made this area more complex and more consequential than ever. If you have not yet reviewed your position, this is the time.
No Property Too Complex
The majority of our valuations are residential houses, farms and land. But we are regularly instructed on properties that many valuers would struggle to advise on.
In recent years we have provided formal RICS valuations for churches and graveyards, mudflats, vineyards, historic monuments, pubs, mobile telephone masts, a mausoleum, access rights, and livestock and machinery on farms.
If you are unsure whether your property type falls within our remit, the answer is almost certainly yes.
