Back in March 2021, we submitted a response (available here) to the RICS review of real estate investment valuations led by Peter Pereira Gray. On 19 October, the RICS published a new UK Supplement to update the Red Book, reflecting the outcome of the review. The supplement and related materials can be accessed here, and the RICS is also offering an overview of the changes via a free webinar at 11am UK on 6 November (register here).
