Harry Hatwell is a civil and criminal regulatory barrister practising from Gough Square Chambers, where he specialises in consumer financial services and consumer protection. He contributed to advice and preparation in the first administrative enforcement action under the DMCCA against Euro Car Parks Ltd, and assisted in drafting the grounds of appeal for Ryanair’s current challenge to CMA enforcement. He is also building experience in insolvency and bankruptcy, including in a long-running case involving rescission of petitions by HMRC in which Harry successfully sought costs on the indemnity basis.

He is co-authoring, with Stuart Jessop and Robin Kingham, the first book on the new direct enforcement regime for consumer law in the UK and he is writing a chapter in the revised version of the leading practitioner text on English food law. Harry also co-edits the consumer credit chapter of the Pink Book (Consumer and Trading Standards: Law and Practice, edited by Jonathan Kirk KC and published by Butterworths).

A graduate of Oxford and Yale Law School, Harry maintains his academic interests through contributing to leading academic and practitioner journals, including the Cambridge Law Journal, Private Client Journal, Professional Negligence, and the Journal of International Banking and Financial Law. In addition to full-time practice, Harry teaches at the London School of Economics and Political Science and teaches, examines, and moderates various private law courses at King’s College London and Queen Mary University of London.

Before transferring to the Bar, Harry trained as a solicitor at Slaughter and May, where he worked on the Municipio de Mariana class action, for Warner Music Group in the CMA music streaming market study, and for Asda in the CMA's greenwashing fast fashion investigation.
