EU & Competition Law

Their expertise and intercultural legal knowledge is exceptional.

Legal 500 2026, testimonial

EU and competition law aims to promote fair markets, prevent anti‑competitive behaviour and ensure that businesses compete on a level playing field. Organisations operating nationally or across borders must navigate detailed regulatory frameworks that govern pricing, collaboration, market dominance, mergers and commercial conduct. With regulators increasingly active and enforcement becoming more assertive, understanding these rules is essential to avoid penalties and maintain compliance.

Competition issues arise in a wide range of scenarios, including joint ventures, supply agreements, distribution models, procurement activities and strategic partnerships. Businesses must ensure that commercial arrangements are structured in a way that supports their objectives without infringing competition rules. In parallel, EU regulation continues to influence sectors from technology to transport, shaping how companies trade and innovate.

A clear, well‑informed approach empowers organisations to make strategic decisions with confidence. By understanding the boundaries of acceptable conduct, businesses can pursue growth while maintaining transparency and regulatory integrity.

Keystone’s team of EU and competition lawyers understand the workings of all regulating authorities and will ensure your organisation remains fully compliant. When it comes to obtaining or maintaining commercial advantage, the team knows how to challenge the anti-competitive behaviour of other businesses.

Our EU and competition lawyers advise public and private sector clients across a number of diverse sectors. Our industry knowledge and credibility will ensure we grasp the issue at hand and counsel you towards the very best outcome.

We also work with other law firms who do not have particular expertise in this area.

The team consists of industry experts who have specialised in EU and competition law for decades, both at EU and UK level. When instructing our team of lawyers or barristers, you can be sure that the quality of the work will be at a very high standard.

Our team of EU and competition law experts understand the additional responsibilities given to companies with significant market power not to use that power in a way which reduces, restricts, or distorts competition. We regularly advise companies that hold or may hold dominant market positions to determine whether the rules affect them and if so, how they can ensure compliance with the minimal disruption to their commercial positions.
