Unless otherwise provided for in the specific call/topic conditions, only legal entities forming a consortium are eligible to participate in Horizon Europe actions provided that the consortium includes, as beneficiaries, three legal entities independent from each other and each established in a different country as follows:

• at least one independent legal entity established in a Member State;
• and at least two other independent legal entities, each established in different Member States or Associated Countries (this includes the UK).

Our European team can help you find eligible partners to form a consortium.

There may be further eligibility conditions for specific topics. Please check the Work Programme and contact our team to ensure your eligibility before applying.
