I imagine that the Accreditation Body would be interested in the registrars practices as, if this program falls under ISO/IEC 17021-1 there's a clause that says:
It is recognized that the source of revenue for a certification body is its client paying for certification, and that this is a potential threat to impartiality.
and
To obtain and maintain confidence, it is essential that a certification body’s decisions be based on objective evidence of conformity (or nonconformity) obtained by the certification body, and that its decisions are not influenced by other interests or by other parties.
