The reason for this is that the RTPI periodically writes to members, selected at random, to request details of their professional indemnity insurance or continuing professional development. If a member fails to respond, the matter is referred to the complaints investigator as a possible breach of the code of professional conduct. These complaints are referred to the conduct and discipline panel. This can lead to a member being suspended or having their membership terminated.
To avoid any unnecessary investigation and subsequent penalty, which could simply be due to the institute writing to the member at an old residence, it is crucial that members notify the institute of any change of address.
