"A very strong advocate who is excellent with clients. He's a superb barrister."

Harry was appointed a Recorder in Crime on the North-Eastern Circuit in 2022.

Harry acts for companies and individuals in the most serious health & safety prosecutions, including corporate and gross negligence manslaughter.  He has acted for all sizes of business, from sole traders to Plcs, across a wide spectrum of industries, encompassing all aspects of construction, transport management, work at height, electrical installation, swimming pool management, farming, caravan sites, asbestos, care homes and commercial baking.

Harry successfully represented the employer in the Bosley Mill explosion prosecution, led by Dominic Kay KC, and this year, also led by Dominic, successfully secured the acquittal of manslaughter of the Managing Director of Alutrade Limited.  He is briefed in three more manslaughters in the forthcoming year.

He was instructed in the Grenfell Inquiry. He has extensive experience in appeals against Enforcement Notices served under the FSO and achieving the best possible outcomes in high profile cases.
