H2O Law offers reputation management as a core service. The firm attracts many clients from the worlds of entertainment (actors, celebrities and musicians), politics and business. Whether defending rights or facilitating media public relations campaigns, H2O Law provides clients with a comprehensive service.

H2O Law also has a strong defendant client base, acting for newspapers, magazine publishers and campaign groups. It acts to protect the media's right to investigate and to criticise, and to protect the freedom of speech generally.

H2O Law does not provide legal services in isolation. The firm works closely with other professionals and addresses legal issues from a combined standpoint of law, business and public relations. Knowledge of the law is not enough; knowledge of the industry in which the client operates is essential.
