The RICS Red Book —the colloquial name of RICS Valuation – Global Standards— is the body of professional valuation standards published by the Royal Institution of Chartered Surveyors (RICS). It incorporates the International Valuation Standards (IVS) and adds mandatory compliance requirements for RICS-regulated valuers and firms: an identified purpose for the engagement, an explicit basis of value, traceable methodology, inspection of the asset, documented independence and the signature of a qualified professional. When a bank, an auditor or a court asks for “an RICS valuation”, what it is asking for is a Red Book-compliant report.
That compliance separates a report accepted without discussion from an estimate no one stands behind. This guide explains what the Red Book is, what it requires of a report, who may sign one, why banks and courts demand it, and how to check in the RICS public register that the firm you engage is actually regulated.
What is the RICS Red Book?
The Red Book is the core normative publication of RICS, the world’s leading authority on valuation. Its formal title is RICS Valuation – Global Standards: a globally applicable body of standards governing how a valuation engagement is accepted, how it is carried out and how it is reported. The colloquial name comes from the colour of the printed edition’s cover.
The standard’s authority rests on the institution that issues it. RICS was founded in London in 1868 and has operated under Royal Charter since 1881, a statute by which the British Crown delegates to it the power to regulate the chartered surveyor profession. Today it brings together more than 134,000 professionals across 146 countries, and its framework is the default reference for valuing industrial and non-real-estate assets in Europe. The global edition of the Red Book is revised periodically —it is published every 2-3 years— and the current edition is the 2025 one.
For an RICS-accredited valuer, the Red Book is not an optional best-practice guide: applying it is mandatory in virtually all engagements, and non-compliance carries disciplinary consequences.
How does the Red Book relate to the IVS?
The International Valuation Standards (IVS) are the global umbrella framework for professional valuation. They are issued by the International Valuation Standards Council (IVSC), an independent international body in which RICS itself participates institutionally.
The Red Book does not compete with the IVS: it implements them. It translates their general principles into concrete operational requirements —inspection practices, minimum report content, the valuer’s ethical obligations— and adds the supervisory apparatus the IVS alone do not have. The practical consequence is direct: a Red Book-compliant report is, by construction, IVS-compliant. That is why it works as the technical lingua franca in international transactions, with recognised operational equivalence to the American USPAP.
What does the Red Book require of a valuation report?
A Red Book report is not distinguished by its final figure, but by how that figure is reached and how it is documented. The minimum requirements are auditable:
- Identification of the purpose. The report states what it is issued for —bank security, an M&A transaction, IFRS reporting, an insurance claim, court proceedings— because the purpose determines the applicable basis of value.
- An explicit basis of value. Every figure is anchored to a declared basis: Market Value, Fair Value (IFRS 13), Fair Market Value, orderly (OLV) or forced (FLV) liquidation value, reinstatement value new or depreciated (VRN/VRD). The same asset has different values depending on the question being answered.
- Justified valuation approaches. The valuer applies —and explains— the cost, market or income approach; for assets without a liquid secondary market, several are combined and the resulting range is reconciled. A third party must be able to reconstruct the reasoning from the cited sources and comparables.
- Inspection of the asset. Unless a desktop engagement is expressly agreed, the asset is inspected on site and its technical condition, residual useful life and levels of obsolescence are documented.
- An agreed scope of work. What is inspected, what is assumed and what limitations exist is agreed in writing before the work begins.
- The valuer’s independence. The report records that neither the signatory nor the firm has any conflict of interest with the transaction, the assets or the parties.
- The signature of a qualified professional. The report is signed by a valuer holding an RICS designation —usually MRICS or FRICS— with documented experience in the asset type.
What is an RICS Registered Valuer?
The letters next to the signature on a report are not decorative. RICS accredits its members through individual designations —AssocRICS, MRICS and FRICS— which require training, audited practical experience and passing the Assessment of Professional Competence (APC), plus a minimum of 20 hours of continuing professional development (CPD) per year, recorded and auditable.
On top of that, anyone practising valuation under the Red Book must also join the Valuer Registration (VRS) scheme: the quality-assurance programme through which RICS specifically supervises valuation practice. An RICS Registered Valuer is a member enrolled in that register and subject to its monitoring. An RICS-regulated firm is a company admitted to the same scheme, subject to periodic audits of its processes, conflicts of interest, internal training and documentary traceability, and required to maintain professional indemnity insurance. It is not a passive certification: it is active supervision, formal complaints mechanism included.
The distinction matters: an individual MRICS is qualified; a regulated firm extends RICS’s responsibility and supervision to company level, which is exactly what a risk committee wants to see.
Why do banks, auditors and courts ask for a Red Book report?
Because it outsources trust: whoever receives the report does not have to assess the valuer, because the standard and its supervision have already done so.
- Financial institutions. In asset-backed finance —ABL, sale & leaseback, refinancing—, the bank requires an independent Red Book valuation with FMV and OLV calculations before accepting machinery, vehicles or industrial premises as collateral for a loan. The client’s internal valuation is not accepted.
- Auditors. Fair value under IFRS 13 and purchase price allocation (PPA, IFRS 3) require a documented professional valuation; the Red Book is the framework the major audit firms accept directly.
- Insurers. The calculation of the insurable value (VRN/VRD) for industrial policies starts from the same normative basis and prevents underinsurance.
- Courts and insolvency administrators. Full methodological traceability makes the report defensible in court: every figure has documented inputs, sources and method, and the valuer answers for it.
- Cross-border transactions. When a deal crosses jurisdictions, the Red Book is the standard every counterparty recognises.
What separates a Red Book report from an unregulated appraisal?
An unregulated appraisal may contain a reasonable figure; the problem is that no one can verify it. Without a declared basis of value, the figure answers no specific question. Without traceable methodology, it cannot be reconstructed. Without documented independence, bias cannot be ruled out. And without a regulator behind it there is no supervision, no mandatory insurance and no complaints mechanism to turn to if something goes wrong.
A Red Book report reverses the burden: it starts from the right question (purpose and basis of value), documents the asset’s actual condition, adjusts for technical and functional obsolescence and leaves the full reasoning inside the document. If anyone challenges it —an auditor, a counterparty, a court—, the answer is already written. That is the operational difference: not that the figure is “higher” or “lower”, but that it is defensible.
When the mandate arrives in English from an Anglo-Saxon parent company, the confusion starts earlier: appraisal is not the same as an expert opinion, nor as any assessment. We work through the exact equivalences between appraisal, regulated valuation and each basis of value in what appraisal means in industrial asset valuation.
How do you verify that a firm is regulated by RICS?
RICS regulation has an advantage no self-proclaimed seal can offer: it can be checked in minutes, without asking anyone’s permission. RICS maintains a public register at rics.org where anyone can verify both individual professionals and regulated firms.
Before commissioning a valuation, check three things:
- The signing valuer exists in the register, with their designation (MRICS or FRICS) and membership number.
- They are listed as an RICS Registered Valuer, i.e. enrolled in the Valuer Registration scheme.
- The firm appears as a regulated firm in the official RICS directory.
It is the same check a bank, an auditor or a risk committee performs before accepting a report. On our RICS regulation page we link directly to the public profiles of our valuers and of the firm itself, so verification does not even require a search.
How Capital Appraisal applies it
Capital Appraisal is an RICS-regulated firm operating under the Valuer Registration scheme. All our industrial asset valuation reports are prepared in accordance with the Red Book: identified purpose, explicit basis of value, traceable methodology, documented inspection and the signature of an RICS Registered Valuer. It is the guarantee that the report will serve its intended purpose —before the bank, the auditor or the court— and that it will continue to do so if anyone calls it into question.
