August 2026 marks the 50th Anniversary of RICS Valuation – Global Standards, more commonly known as the “Red Book”.

The Red Book is a globally recognised framework that underpins consistent, transparent and high‑quality valuation practice. It sets out overarching principles of ethics, objectivity, competence and transparency, which guide professional judgement across all valuation work.

Covering everything from the terms of engagement to reporting requirements, the Red Book plays a critical role in financial reporting, secured lending and investment analysis where clarity and consistency are essential.

Built on RICS’s long‑standing commitment to clear, objective standards and regulation, the Red Book has become an authoritative benchmark of valuation standards, providing confidence, integrity and trust in valuations delivered across global markets.

Frequently Asked Questions

The Red Book is used internationally, by a wide variety of financial institutions, built environment, and specialist valuers such as arts and antiques.

  • Real estate and built environment – including residentials, commercial property, leisure, mixed-use developments, healthcare, education, student accommodation, operational properties such as power stations and airports.
  • Land and rural – development land, agricultural land and estates, forestry, mineral and waste interests.
  • Financial and statutory – financial reporting, secured lending, investment valuation, taxation (e.g. probate), litigation and dispute resolution, compulsory purchase.
  • Specialist and alternative assets – infrastructure assets, energy assets, trading-related properties such as pubs, petrol stations, plant, machinery and equipment, arts and antiques.

The Red Book is published every two years. Before each new edition a consultation will take place allowing users to feedback on novel areas, suggested amendments and specific clarification while aligning closely with International Valuation Standards (IVS). For instance in 2011, the edition included new guidance on valuation certainty to reflect the change in market conditions due to the credit crunch.

In 1973, a joint working party was set up by RICS and the Institute of Chartered Accountants in England and Wales to report on the valuation of property assets following the 1972/73 property boom and the subsequent collapse of the property market, which gave rise to considerable public criticism of the variety of valuation bases used and the format of reports.

In 1976, the first edition of Guidance Notes, The Valuation of Assets was published.
