When buying, selling, or refinancing commercial property, an accurate and credible valuation is essential.
One of the most widely recognised forms of property valuation in the UK is the RICS Red Book Valuation – but what exactly does that mean, and when might you need one?
Sus López-García, a RICS-Registered Valuer and Partner based in our Woking office in Surrey, explains.
What is a Red Book Valuation?
A Red Book Valuation is a formal property valuation carried out in line with the RICS Valuation – Global Standards, often referred to as the “Red Book” because of its original red cover.
Published by the Royal Institution of Chartered Surveyors (RICS), these standards set out the rules and best practice for valuers, ensuring consistency, accuracy, and transparency.
In short, a Red Book Valuation provides an independent, professional, and regulated assessment of a commercial or residential property’s market value, prepared by a qualified RICS Registered Valuer.
Why is it called the “Red Book”?
The name comes from the RICS manual itself, which historically had a red cover.
Today, while the document is digital, the term has stuck – and is now widely used across the property industry to signify a valuation that meets strict professional standards.
When is a Red Book Valuation required?
Red Book Valuations are commonly required in situations where an official, reliable value of a property is needed, including:
- Secured lending / mortgages – lenders often require a property valuation for secured lending before approving finance.
- Accounts and financial reporting – businesses may need a valuation for company accounts, audits, or valuations for financial reporting.
- Tax purposes – such as property valuations for probate, inheritance tax, capital gains tax, or stamp duty purposes
- Dispute resolution – including matrimonial proceedings or partnership disputes.
- Acquisitions and disposals – investment property valuations for investors, developers, or occupiers considering purchase or sale.
What makes a Red Book Valuation different?
Unlike an informal market appraisal, a Red Book Valuation must follow strict professional standards:
- Independence – provided by a qualified, impartial RICS Registered Valuer.
- Compliance – in line with the RICS Red Book Global Standards.
- Transparency – clear methodology and evidence underpinning the valuation.
- Accountability – the valuer is regulated by RICS, providing reassurance to clients, lenders, and HMRC.
This makes Red Book Valuations highly reliable and trusted across the industry.
