PJ Kirby KCGatehouse Chambers ‘One of the stand out cost silks, his narration through complex legislation is superb.

With ‘a good selection of counsel available at all levels‘, Gatehouse Chambers has in recent years developed a small but strong costs litigation offering. Standout silk PJ Kirby KC led Robin Dunne in Belsner v CAM Legal Services, acting for the former party in what is an important test case concerning the provisions of s.74(3) of the Solicitors Act and was seen at the Court of Appeal in February 2022. Martyn Griffiths regularly appears at the Senior Courts Costs Office and the County Courts on detailed assessments as well as interim applications in costs proceedings. Alaric Watson is one to watch in the costs arena as his insolvency practice has leaned heavily into costs work recently.
