The review also finds that members are struggling to understand how the structure of the RICS works and how they can engage with it, particular on a local basis.
The document says: "This also results in a low level of understanding as to where to go for certain information."
The Brooke review concluded that while members felt that communication had improved, many felt that they were inundated with information, some of which was was not relevant to their particular interests.
The review notes: "As the RICS has moved to a higher level of e-based communication, members who have not supplied email addresses are consistently missing out."
It concludes that the rules and governance processes of RICS lack sufficient clarity.
The review states: "This has led to a high degree of suspicion and a feeling that RICS is not there to serve its members."
The Brooke review follows a campaign led by Jeremy Hackett, a QS at Schofield Lothian, against an increase in membership fees. Hackett said last month he was taking legal advice to challenge the RICS decision to increase membership fees by a third.
