Changes in UK participation in EU programs: what it means for companies with British partners

Key data

Spanish companies, universities and research centers working with British partners in European programs should pay attention to Council Decision (EU) 2026/833, adopted on 30 March 2026. This regulation establishes the official position of the European Union before the Specialized Committee on Participation in Union Programs, the body created by the EU-United Kingdom Trade and Cooperation Agreement to manage precisely these matters.

The purpose of the decision is to agree on modifications to Protocol I of that agreement, which is the text that regulates in detail how and under what conditions the United Kingdom can continue to participate in certain European programs after Brexit. Any change to that protocol has direct consequences for consortia and projects that include British entities.

What does this regulation establish?

Protocol I of the EU-United Kingdom Trade and Cooperation Agreement is the legal framework that defines three key elements for British participation in European programs:

• Financial contributions: what the United Kingdom contributes to the budget of the programs in which it participates.
• Access conditions: the requirements under which British entities and companies can apply for European calls and projects.
• Supervision mechanisms: how the participation of United Kingdom entities in such programs is monitored and audited.

Decision 2026/833 does not directly modify these elements, but rather sets the position that the EU will defend in the Specialized Committee to agree on those modifications. In other words, it is the preliminary step to concrete changes: the EU defines its negotiating mandate before sitting down with the United Kingdom to finalize the details.

This process is part of the ongoing management of the post-Brexit relationship and reflects that the conditions for United Kingdom participation in European programs are not static, but are reviewed and updated through this bilateral mechanism.

Economic and operational impact

The specific impact will depend on the outcome of negotiations in the Specialized Committee, but the three areas that may be modified have real operational consequences for any organization working with British partners:

For consortia already underway, any change in access conditions or supervision mechanisms may require adjustments to consortium agreements and project administrative management. For those preparing new proposals, it is advisable to wait to learn the outcome of negotiations before finalizing the consortium structure.

Who does it affect?

This regulation directly affects Spanish and European organizations that collaborate or plan to collaborate with United Kingdom partners in EU programs. Specifically:

• Technology and innovation companies participating in R&D projects with British partners (for example, under Horizon Europe).
• Universities and research centers with international consortia that include institutions from the United Kingdom.
• Public bodies and educational sector entities collaborating with British partners in higher education and cooperation programs.
• European project managers (project managers, project offices) coordinating mixed EU-UK consortia.
• Advisors and consultants specialized in European funding advising clients with partners in the United Kingdom.

Practical example

A Spanish biotechnology company participates as coordinator in a European research consortium that includes a United Kingdom university as a partner. Currently, the participation conditions of that university are regulated by Protocol I of the EU-UK Agreement.

If the modifications that the EU intends to agree in the Specialized Committee affect the access conditions for British entities, the coordinating company will need to review whether the university remains eligible under the same conditions, or if it is necessary to adjust the consortium agreement. If the changes affect the supervision mechanisms, there may be new reporting obligations that increase the administrative burden of the project.

In projects in the preparation phase, the recommendation is to monitor the outcome of negotiations in the Specialized Committee before formalizing the consortium structure with British partners.

What should companies do now?

1. Identify if you have active or planned projects with United Kingdom partners in European programs for R&D, education or cooperation. If so, this regulation directly affects you.
2. Review current consortium agreements to understand what participation conditions currently apply to your British partners and what scope exists to adapt them if the rules change.
3. Monitor the outcome of negotiations in the Specialized Committee on Participation in Union Programs. Decision 2026/833 sets the EU's position, but concrete changes to Protocol I will be agreed in that committee.
4. Consult with your project manager or European funding advisor on the potential impact on ongoing or planned proposals that include United Kingdom entities.
5. Do not finalize the structure of new consortia with British partners until you have clarity on the final conditions that will result from the modifications to Protocol I.
