Frederick Simpson

Call 2018

Frederick practises across chambers’ core areas, with a particular focus on construction, insurance, professional liability and property damage. He advises and represents clients in both the High Court and County Court, on paper and on his feet, at first instance and on appeal. He enjoys working both alone and as part of a team of barristers. He is regularly instructed in the early stages of a claim, often pre-action, to assist in setting the overall strategy and preparing correspondence and pleadings. In addition to his litigation work he frequently represents clients in all forms of ADR including adjudication, mediation and joint settlement meetings, both alongside litigation and as an alternative.

Frederick read Philosophy at Cambridge. Prior to becoming a barrister he spent seven years in the British Army as an infantry officer. In appropriate cases Frederick provides advice or representation pro bono as part of the Bar’s Advocate scheme.
