The firm:
Founded in 2019 by Damon Parker, Harcus Parker has established itself as one of the UK’s leading firms for collective redress. The firm is known for acting on a fully contingent basis in suitable cases and has built strong relationships with litigation funders and ATE insurers. Its work spans the full lifecycle of collective and multi-party claims, including opt-in and opt-out proceedings before the Competition Appeal Tribunal, High Court actions under Group Litigation Orders, and employment-based multiple claims.

The firm acts on behalf of consumers, investors, employees, and small and medium-sized enterprises in claims against large corporates and financial institutions. Its commitment to innovation in litigation strategy and funding models has enabled thousands of claimants to pursue access to justice in circumstances where it might otherwise be out of reach.

Types of work undertaken

Financial services and shareholder actions:
Harcus Parker has a strong heritage in financial litigation, with its team having acted in some of the most significant shareholder claims in the UK. The firm brought the UK’s first securities group action and has played a pivotal role in shaping the use of collective redress in this area. It continues to act in large-scale claims against financial institutions on behalf of retail and institutional investors.

Consumer claims:
The firm represents groups of consumers who have suffered financial loss or harm as a result of corporate misconduct. This includes claims involving hidden charges, misleading practices and failures in duty of care by major service providers. Harcus Parker is currently involved in several large-scale consumer actions before the High Court and Competition Appeal Tribunal.

Equal pay litigation:
Harcus Parker acts for tens of thousands of claimants in some of the largest equal pay claims in the UK. These include high-profile actions against major supermarket chains, where store-based employees are seeking parity with warehouse-based colleagues. The firm has developed specialist knowledge of the legal and procedural issues specific to equal pay group claims, particularly within the Employment Tribunal's multiple claims regime.

Competition law:
The firm is active in both opt-in and opt-out claims before the Competition Appeal Tribunal, representing groups of businesses and consumers affected by anti-competitive practices such as price-fixing and abuse of dominance. Harcus Parker is involved in claims against global manufacturers and service providers, with damages sought in the hundreds of millions of pounds.

Data breach and privacy claims:
Harcus Parker has an emerging practice in data breach litigation, acting for individuals whose personal data has been mishandled by corporates or public sector bodies. These claims are often brought on a group basis and include both representative actions and traditional group claims under High Court case management.

Commercial litigation:
Beyond collective actions, Harcus Parker also acts in complex commercial disputes on behalf of businesses and investors. Its lawyers have experience in fraud claims, breach of contract disputes, and professional negligence matters. The firm regularly advises on issues involving offshore structures, financial mis-selling, and multi-jurisdictional litigation strategy.
