The Burnside Partnership Story


Our firm was founded in June 2015 by Anna Burnside and the late Fiona Wheeler, both recognised Private Client Solicitors, who worked together for more than 10 years. Today we are evolving into a new breed of private client consultancy, one that supports our clients with life, not just law.

Though the scope of our work continues to grow the philosophy that guides what we do remains the same. Anna and Fiona established the firm to provide technically excellent advice delivered with sensitivity, in a clear and straightforward manner, and that is what clients continue to value from us today.

The Fiona Wheeler Charitable Foundation was established in memory of Fiona. For more details, please

Our Team

We represent clients from all walks of life and we act not just as lawyers and tax experts but as trusted advisers. We are committed and down to earth and work quickly, confidently and yet with sensitivity. We like to get to know our clients and understand their concerns and priorities.
Making decisions about one's personal affairs, especially estate planning can be daunting or distressing for some clients. All our staff are responsible for achieving a professional, yet friendly and empathetic, experience for our clients. We pride ourselves on the quality of our professional advice and our approach to client care. This approach means that clients are less likely to delay making decisions and more likely to have in place well thought through, practical and tax-efficient arrangements.
