The story behind the concept…
The Fenton Private Office is not a new idea - it is an established model.
These models reject the assumption that the delivering firm must employ every discipline in-house. They put a premium on the selection and direction of specialists over the employment of generalists.
In global mobility and cross-border tax advisory, neither model has been applied — until now…
The Barristers’ Chambers model.
The barristers’ chambers model is centuries old and structurally similar to the Fenton Private Office. It endures because it solves a fundamental problem: the best person for the job might not work for your firm. By keeping practitioners independent and selecting on merit for each engagement, the model ensures the client’s interests — not a firm’s internal economics — determine who advises them.
Everyone is independent. The client gets the best advocate for their specific matter, not whoever happens to be available and employed by that firm.
The Family Office model.
The family office emerged because wealthy families discovered that no single financial institution could provide genuinely integrated, independent advice across all their affairs.
The family office exists to sit above all of these — to direct, coordinate and be accountable for the whole picture.
Prestigious and global financial brands all operate versions of this model for clients who need the function without the cost of building their own office where they get one accountable adviser assembling and directing the right specialists around them unique needs.
What Makes Us Different
1.Senior-led
Every engagement is led by an senior and experienced cross-border tax leader, not delegated to a junior team.
Our team has held multiple senior leadership and board-level positions in HR, reward, and governance, managing budgets, delivering and setting strategy, and boardroom scrutiny. We bring the practical judgement of people who have owned the problem — not only advised on it.
2.Alignment
Tax, social security, pensions, payroll, reward, HR, policy, immigration, legal, relocation and governance are coordinated as one — not siloed across teams that aren’t joined up or independent.
Real accountability and ownership.
3.Global, without country bias
Our planning and advice is based on the client’s position, not on where we happen to have an office.
We optimise our planning for our clients. No hidden agenda.
4.AI & Human Judgement
The latest AI-assisted tools are baked into our model. AI provides support for our experienced advisers with research, helping synthesis large volumes of data and issue-spotting across complex multi-jurisdictions.
AI supports the our experience, senior, human advisers. It does not replace professional judgement, experience and experience. This combination is powerful and helps us provide better, more accurate and more insightful advice.
5.The best expert for each client
Fenton International does not try to employ every specialist in every discipline and every jurisdiction. We keep it simple.
We maintain a curated network of senior specialists, chosen on merit for each client, and specific assignment.
This is a structural advantage - we select the best person for the job — not the best available person within a firm’s headcount.
6.Industry Credentials
Our advisors bring decades of experience advising employers, individuals and boards on complex cross-border matters at every level of seniority and sensitivity. We have worked across financial services, life sciences, technology, professional services and regulated industries, giving us the depth and the breadth across sectors to handle problems that sit between specialisms. Our professional qualifications span tax, reward, HR, and global mobility.
