Eileen Carroll KC (Hon) is one of the most senior and sought after mediators in practice today with over 27 years’ experience as a full time practitioner. She works with clients across a very broad commercial perspective on claims relating to dozens of different sectors and activities around the world.


Her work includes highly complex multi-party disputes valued at up to £1 billion including the Maxwell pensions scandal, PPI misselling, BCCI and British and Commonwealth Holdings. Clients on all sides have praised Eileen’s mediation work as “masterful”, “extraordinary”, “phenomenal”, “above and beyond” and “different and more valuable than other mediators”.


The value of her casework in recent years has ranged from £200k up to £100+ million and her clients have included business entrepreneurs, public sector organisations, celebrities, international corporations and sovereign states.


“Incredible mind which enables her to get to the bottom of any issue; she is everything you would want in a mediator” she is one of the market’s most popular mediators.“ Clients speak of her incredible patience and resolve, as well as an engaging and constructive manner which can help difficult parties to move more quickly towards resolution. “She led the most effective opening session I have ever seen,” said one instructing solicitor.


Eileen is the co-founder of CEDR and recognised as one of the pioneers of mediation techniques in the U.K. In 2013 Eileen was awarded Queen’s Counsel Honoris Causa by the Ministry of Justice for her “outstanding career as a commercial mediator and her unique contribution in establishing mediation in civil justice systems over the last two decades”.


Eileen began her career in the international chemical industry before becoming a partner in the city law firm Turner Kenneth Brown (now Nabarro). In over 20 years of practice Eileen worked with multinational corporations and a number of celebrity clients based in Europe, the Far East, India and the United States.

One of Eileen’s most notable strengths is her ability to relate to a wide range of individuals and to build almost instant personal rapport with the parties and gain their trust. Her approach is both facilitative and evaluative and although she believes you have to gain co-operation and trust, a mediator should not shrink from helping the parties re-evaluate their options and strenuous reality testing may be a necessary part of the process. “She manages an excellent balance between gaining the clients’ trust and raises issues for their consideration.” Partner, City Law Firm She is very numerate and will crunch through the numbers and make sense of otherwise complex materials. She is highly intuitive and sensitive and never loses sight of the parties’ own responsibility to decide whether to settle. She is respected for her confidence and strength and has impressed parties with her “judicious use of toughness” to help bridge that last gap while maintaining their trust. Clients also appreciate the time she has taken to read into complex material and use the knowledge to shape a meaningful process. “She does not have one style, she is very adaptable and shifts attitude and tactics quickly – she has a real ability to focus on the result. She has the absolute right balance of tough and soft.”
