RICS Red Book (Valuation – Global Standards)
What the Red Book Is
The RICS Valuation – Global Standards, universally known as the “Red Book”, is the professional standard published by the Royal Institution of Chartered Surveyors (RICS) for property valuers. It sets out the mandatory requirements, best practice guidance, and ethical obligations for RICS-regulated valuers when providing property valuations.
In the UK and across most European markets, real estate fund valuations are typically conducted by RICS-accredited valuers following Red Book standards. This makes the Red Book the practical valuation methodology framework for non-listed real estate funds in those markets — distinct from but complementary to the IPEV Valuation Guidelines (which apply across private capital broadly) and IFRS 13 (the accounting standard).
A global edition of the Red Book is published alongside the UK edition; the global edition is increasingly used in international real estate fund contexts.

What the Red Book Covers
At a high level, the Red Book addresses:
Bases of value — The Red Book defines the bases on which valuations can be provided, including Market Value (the most commonly used basis for real estate fund NAV), Market Rent, Investment Value, and Fair Value (consistent with IFRS 13). For fund NAV purposes, Market Value — the estimated amount for which a property would sell between a willing buyer and seller on the valuation date — is the typical basis.
Valuation approaches — Income capitalisation (applying a yield to passing or estimated rental income), discounted cash flow (DCF), and comparison methods. The appropriate approach depends on property type, available market evidence, and the specific valuation purpose.
Independence and conflicts of interest — The Red Book requires valuers to be independent of the property owner and to disclose any conflicts. For real estate funds, the external appraiser appointed for NAV purposes must be independent of the GP.
Rotation and frequency — Best practice guidance on how frequently valuations should be updated and when valuer rotation should occur to preserve independence.
Reporting — Format and content of valuation reports, including assumptions, limiting conditions, and the basis on which the value was determined.
Why It Matters for Alternative Fund Operations
Real estate NAV: For non-listed real estate funds, NAV depends on the value of the underlying properties. Red Book-compliant valuations are typically conducted annually (or semi-annually for some vehicles) by external RICS-accredited valuers. Between appraisal dates, the GP or administrator must determine how to handle the gap — using the most recent Red Book value adjusted for any known material changes.
NAV production: The NAV production process for a real estate fund differs from PE because the primary valuation input is the RICS appraisal rather than a management-led model. Operations teams need to understand the appraisal cycle and how the appraisal feeds into the accounting NAV.
Valuation risk: Red Book valuations involve professional judgement — particularly on capitalisation rates, comparable evidence, and market conditions. The valuation risk concepts of stale prices, smoothing, and subjectivity apply directly to RICS appraisals: annual valuations create significant gaps during which market conditions may change materially.
NAV concepts: For NAV purposes in real estate funds, the property value is typically at Market Value (Red Book) rather than cost or distressed price. Understanding this distinction is important for interpreting real estate fund performance.
Relationship to INREV: The INREV Guidelines for non-listed real estate vehicles build on RICS valuation standards for the property-level inputs but add the fund-level reporting and governance framework. Red Book valuations are the building block; INREV guidelines determine how they are used in fund reporting.
