RICS Knowledgebase

The Red Book UK supplement covers shared ownership at pages 75 and 105 and also see part 6 of 

Right to Shared Ownership: initial guidance for registered providers - GOV.UK (www.gov.uk)

The majority of Housing Associations will have some very specific rules regarding the valuation process. For example, some of the shared equity valuations may require the valuer to disregard any improvements made to the property since acquisition. Other shared equity valuations request specific information to be provided regarding comparable evidence and the details within the valuation report.

The Government states in their guidance about selling a shared ownership property that anyone valuing for a shared ownership property must be a member of the RICS. This could be any RICS Registered Valuer  (AssocRICS, MRICS or FRICS) who has the necessary experience and expertise (as per rule 2 of the RICS Rules of Conduct). 

There may be certain lender policies (similar to a Bank’s own lender guidance) which sets out an experience criteria, for example, but, this is not something that RICS specify and experience is not necessarily the same as member grade. Similarly some Housing Associations may set their own criteria either in the lease or other documentation.

The Shared Ownership Council issued a voluntary Shared Ownership Code in June 2025
