Overview


Kate Vaughan-Neil is a highly sought-after barrister with a particular focus on professional negligence, , insurance and other commercial litigation; as well as financial services work (including advice on regulatory issues). She appears in substantial court and arbitration matters as both sole and junior counsel.

Her standing in the professional negligence field is demonstrated by her nomination as Professional Negligence Junior of the Year 2026 by Legal 500 (and classification as a leading junior). The latest edition states “Kate manages situations with confidence and aplomb, providing reassurance, focus and firm guidance. Kate rises to the challenge of the unexpected, relishing the creative freedom and nailing her client’s objectives every time.”

Her professional negligence expertise covers most of the main professions, with particular emphasis on those involving solicitors, architects and engineers; but also surveyors, barristers and financial advisers. She is well versed in both advising at the pre-action stage and acting in litigation.

Kate is also ranked by Legal 500 as a leading junior in insurance, her practice in which is varied and extensive. In recent years, she has undertaken substantial repeat acting for a major insurer; a company engaged in managing insurance portfolios in run-off; and a company engaged in acting for policyholders in relation to both claims and policy renewal. That (ongoing) experience embraces advising on coverage-related issues of insurance law and policy interpretation; drafting revisions to policy wording as part of renewal negotiations; as well as assisting in the analysis and presentation of claims, not least regarding a number of business interruption policies in light of the FCA v Arch decision and subsequent jurisprudence.

As regards her wider commercial experience, Kate has deep and longstanding expertise in commercial litigation in a variety of contexts (including advising at the pre-action stage). She has recently appeared as junior counsel for a major energy supplier in a trial of four lead “energy commission” cases, successfully defending the SMEs’ claims for commission paid to brokers in relation to their energy supply. She is also instructed by the same energy supplier in respect of the related claims being pursued against it.

Expertise


Kate undertakes financial services work, and has recently acted both for the FCA and for companies seeking advice on regulatory issues. She was junior counsel for the FCA in a recent three week final hearing before the Upper Tribunal, successfully resisting challenges by two individuals and a bank against Decision Notices imposing lifetime bans and financial penalties arising out of the preparation of a plan to destabilise a Middle Eastern economy by unlawful means. She has also advised a number of companies regarding compliance with FCA regulations.

Further, Kate has been engaged by two major retail banks in respect of two separate FCA Reviews, namely the review into mis-sold interest rate hedging products, where she advised on numerous consequential loss claims; and the review into one bank’s business support unit, where she was part of a panel determining appeals brought by customers against the bank’s determination of its claims under the review. She has also acted a number of times for respondents facing complaints to the Financial or Legal Ombudsman.
