A Landmark Decision for Principal Firms: Defining Responsibility in the AR Model
The Appointed Representative (AR) model has long been a powerful way for firms to grow and operate efficiently. However, it has also come with a persistent question: where does responsibility truly begin and end?
A recent Supreme Court decision has now provided much-needed clarity, offering principal firms greater certainty around the boundaries of their liability.
A clearer line in the sand
At the heart of the ruling is a simple but critical point: a principal firm is only accountable for the activities it has actually agreed to take responsibility for.
This may sound intuitive, but in practice, the position had become blurred—particularly in situations where ARs stepped outside both their contractual remit and the principal’s regulatory permissions. The Supreme Court has now confirmed that liability does not automatically extend to those activities.
For principal firms, this is a significant and welcome development. It reinforces the principle that responsibility should align with both regulatory scope and the terms of the relationship agreed with the AR.
Why this matters now
With heightened expectations around oversight, many firms have been reassessing their operating models. HM Treasury and the FCA have been working together to reassess the AR regime and consider whether additional changes are required to make it safer and fairer for consumers to operate in. However, lines have not often been defined and over the last few years appeared to have been blurred in Court of Appeal decisions. However, the Supreme Court’s decision in relation to Kession Capital Ltd (in liquidation) v KVB Consultants Ltd [2026] UKSC 11 draws the line and clarifies the position that s. 39 FSMA intended all along.
The judgment provides reassurance. It confirms that while principals must maintain strong governance and oversight, they are not expected to underwrite risks that fall outside their permitted business or clearly defined arrangements.
The importance of structure and control
What this decision does not do is reduce the need for robust frameworks. If anything, it places even greater emphasis on getting the fundamentals right.
Clear agreements, well-defined permissions, and effective monitoring are no longer just best practice—they are essential safeguards. Firms that can demonstrate a well-structured AR model, with appropriate boundaries and controls, will be best positioned to benefit from this clarity.
A more balanced approach
The outcome also reflects a more proportionate balance within the regulatory framework. It recognises that firms should only be responsible for activities they are equipped—and authorised—to oversee.
This is particularly relevant when considering the distinction between different types of clients. Firms that do not operate in certain segments should not be expected to assume responsibility for risks arising in those areas.
What this means for principal firms
For firms operating an AR model, the message is clear. Firm’s must define the scope of their AR relationships precisely; ensure alignment with its regulatory permissions; maintain strong oversight and monitoring processes; and regularly review its governance framework
If done properly, the AR model will remain a highly effective and scalable structure. This decision strengthens that position by bringing greater certainty to how responsibility is applied in practice.
Looking ahead
While the regulatory environment continues to evolve, this judgment provides a solid foundation for principal firms to build on. It offers both clarity and confidence—two things the market has been seeking for some time.
For firms willing to invest in strong governance and clear structures, the opportunity remains significant.
