A RICS Red Book valuation is a written opinion of value prepared by an appropriately qualified valuer under the RICS Valuation – Global Standards. Those standards establish a consistent framework for agreeing the instruction, carrying out appropriate investigations and explaining the valuation clearly. They do not turn value into a fixed fact: valuation remains a professional opinion at a specified date, supported by market evidence and judgement.
The phrase is often used loosely, so it is important to confirm exactly what is being commissioned. A valuation for probate has a different purpose and valuation date from one for a shared ownership transaction or a private decision. The report should identify the client, intended users, property interest, purpose, basis of value and any assumptions or restrictions.
What the Red Book does
The Red Book sets mandatory practices for RICS members undertaking most valuation work. It promotes consistency, objectivity and transparency, while requiring the valuer to have the competence and independence needed for the assignment. It also addresses terms of engagement, inspections, records and the minimum matters a report must communicate.
It is a professional framework rather than a price list or valuation formula. The valuer still has to understand the particular property and market, select relevant evidence and reconcile differences between that evidence and the subject property.
What should be agreed first
Before work begins, the valuer should establish why the valuation is required. The answer determines the appropriate basis, investigations and wording. A report prepared for one purpose should not automatically be reused for another, and a person who was not an agreed user should not assume they can rely on it.
- The client and any other intended users
- The property and legal interest being valued
- The valuation purpose and relevant valuation date
- The basis of value, scope of inspection and information relied upon
- Material assumptions, special assumptions and reporting limitations
Registered valuer and regulated firm
RICS Valuer Registration is a quality-assurance scheme for individual RICS members carrying out valuation work within its scope. Firm regulation is separate and applies to the business. Clients can check both the individual’s relevant experience and the firm’s status rather than relying on a logo alone.
An appropriate valuer should also have current knowledge of the property type and local market. A competent residential valuer may decline an instruction outside their expertise or where a conflict cannot be managed.
What the figure means
The reported figure applies to the stated interest, assumptions and valuation date. Markets move and later information may change the analysis. It is not a promise that a property will sell for that amount, nor does it guarantee acceptance by a court, tax authority, lender, housing provider or other third party.
Read the valuation as a whole. The evidence, assumptions and limitations explain how the opinion should be used and can matter just as much as the figure itself.
