Call: 1992

Nick specialises in clinical negligence work, regulatory and disciplinary work (particularly GDC, MPTS/GMC and GOC) and general healthcare law (particularly inquests). Clients who instruct Nick include patients and their families and healthcare professionals (via their defence organisations or professional indemnity providers) and NHS Trusts (via NHS Resolution).

Nick advised the Royal College of Veterinary Surgeons on their jurisdiction and procedures in cases of adverse health. He is particularly experienced in claims involving GPs. He also has an interest in cases involving dental practice and has advised commercial dental organisations as well as undertaking dental disciplinary work and claims. He is recommended in the areas of clinical negligence and professional discipline in both Chambers UK and The Legal 500, being described as “Very thorough in conference in teasing out the issues but with sensitivity to the clinician. Tenacious in settlement meetings and gives pragmatic advice.” in Legal 500, 2022

Nick was Chair of the Bar Council’s Wellbeing at the Bar Working Group in 2019. He is a longstanding elected member of the PNBA’s executive committee and has organised their annual Clinical Negligence weekend.

Clinical negligence

Nick undertakes clinical negligence claims at all levels for patients, healthcare professionals via their defence organisations or professional indemnity providers and NHS Trusts. His main focus in his current practice is on High Court claims of high value or where there is particular medical complexity. He is particularly experienced in claims involving GPs.


Nick is regularly instructed to appear at inquests, either on behalf of healthcare professionals/institutions or for families of the deceased, where death occurs in hospital or where healthcare professionals are Interested Persons. His background of undertaking criminal cases in his early practice, together with his current clinical negligence and regulatory/disciplinary practice, make him well aware of the competing pressures and issues arising out of such inquests.

Nick has a substantial regulatory and disciplinary practice. He represents healthcare professionals, principally at the General Dental Council, Medical Practitioners Tribunal Service (formerly GMC) and General Optical Council.

He has also appeared at the Nursing & Midwifery Council, Health Professions Council and the Family Health Services Appeal Authority (now First Tier Tribunal, where he has also been instructed on behalf of Primary Care Trusts).

He advises on and appears in applications for JR and appeals to the Administrative Court arising out of professional disciplinary proceedings.

From 2006 to 2016, Nick was a Legal Adviser to the General Pharmaceutical Council.

Nick’s longstanding interest in dental work has led to him advising several dental corporate bodies in a regulatory context. He has been involved in advising and representing national optical chains in the most important cases at the GOC in recent years.
