Expertise

Construction Litigation

Catherine’s core practice is in construction and engineering disputes, and she is recognised as leading counsel in this field by Chambers UK, Chambers Global and Legal 500. She regularly acts in cases concerning defective works, payment disputes, final account disputes and prolongation claims as well as professional negligence claims made by and against construction professionals.

Catherine excels at understanding and analysing the technical aspects of such claims, in order to provide an appropriate strategy for the case designed to achieve the best outcome for her clients.

Catherine is particularly skilled at leading the client, expert and legal team to produce the required material in the short time available, without compromising on the depth of analysis or technical detail required to achieve a successful outcome.

Property Damage

As a result of her reputation and excellent understanding of technical issues in construction claims, Catherine is regularly instructed at an early stage to advise on and act in claims concerning damage caused by fire, floods, leaks and explosions.  She is then able to lead on the strategy to ensure a successful outcome.
