How to Build a Consortium and Find Partners for a Horizon Europe Project

To build a consortium for an EU project, confirm the call's minimum composition, define the expertise and organisation types you need, then source partners through the Funding & Tenders Portal Partner Search Tool, CORDIS, National Contact Points, and your own network. For most Horizon Europe collaborative calls, you need at least three independent legal entities, each established in a different EU Member State or Associated Country, with at least one based in an EU Member State. Horizon Europe, the EU's key research and innovation programme running from 2021 to 2027 with a total budget of EUR 93.5 billion, allocates the vast majority of that funding through competitive calls that require or strongly favour consortium applications (EURAXESS, Looking for partners to prepare a Horizon Europe proposal).

A consortium is a group of independent legal entities that jointly design, submit, and implement an EU-funded project. Each contributes distinct expertise, resources, and credibility. In EU grants the consortium is normally composed of the coordinator and the other beneficiaries, plus affiliated entities and associated partners, and sometimes subcontractors or third parties that contribute to the action (HE AGA, Article 1.1).

The quality of your partnership is not a formality. Horizon Europe evaluators assess whether your consortium can realistically deliver the objectives. The award criteria include Excellence, Impact, and Quality and Efficiency of Implementation, with the implementation criterion explicitly covering the complementarity, collective competence, and capacity of the team (Horizon Europe Work Programme General Annex D). This article shows you how to move from a project idea to a credible, well-governed consortium.

What Are the Minimum Consortium Requirements in Horizon Europe?

For most Horizon Europe collaborative actions, the minimum requirement is three independent legal entities, each established in a different EU Member State or Associated Country, with at least one based in an EU Member State. This three-country rule ensures the cross-border cooperation and European added value that the Commission designs its programmes to foster (UKRO, Horizon Europe Finding Partners and Building a Consortium factsheet, August 2024).

Note that the three-entity minimum does not apply universally across all action types. For co-funded partnership calls, the rules differ: multi-beneficiary projects under those calls must involve at least two independent legal entities from two different EU Member States or Horizon Europe associated countries receiving financial support, and they may additionally include entities from non-associated third countries that do not receive EU funding. Mono-beneficiary projects under co-funded calls require only one EU or associated-country entity receiving funding, plus at least one non-associated third-country entity that does not receive EU funding (HE AGA, Article 44). Always read the Topic page to identify which rule applies to your call.

Most funded projects go well beyond the minimum. The right number of partners depends on the topic requirements, the expected outcomes and impacts, the activities proposed, and the available budget. A common mistake is padding a consortium to look impressive: every partner should have a clear, non-redundant role.

When a third-country institution joins a consortium, the composition rule is more specific. The EURAXESS guidance clarifies that the consortium must include at least one partner from an EU Member State and at least two additional partners from two other different countries that are either EU Member States or Horizon Europe associated countries, meaning all three of those partners must come from EU Member States or associated countries before a third-country entity can be added (EURAXESS, Looking for partners to prepare a Horizon Europe proposal). Eligibility for automatic EU funding for third-country entities is subject to conditions, so verify the specific call.

Some topics set different eligibility conditions, requiring more partners or specific organisation types, such as mandatory participation of entities from designated countries in areas where international cooperation is required. Always read the Topic page conditions before you start recruiting.

• Minimum three independent legal entities from three different eligible countries (for most standard collaborative actions).
• At least one entity from an EU Member State.
• For co-funded partnership calls, the minimum drops to two EU/associated-country entities for multi-beneficiary projects.
• When a third-country partner joins, all three of the core partners must be from EU Member States or associated countries.
• Topic-specific conditions can widen or narrow eligibility, so verify each call.

You can confirm whether your organisation is eligible by checking the call conditions on the Topic page in the Funding & Tenders Portal Online Manual, which sets out who can apply and the multi-participant action rules.

How Do You Define the Right Partner Profile?

Define your ideal partner profile before you contact anyone: identify the core competencies your project needs, the organisation types required, the geographic coverage, and the specific role each partner will play. Treating this like a job description keeps your search targeted and helps evaluators see how your consortium functions as a cohesive whole (Future Needs, 7 steps to find the right EU project partner).

Start from the call topic and your project concept, then map the gaps in your own capacity. A well-defined profile answers four questions:

• Competencies: which expertise is critical to success, for example AI, climate adaptation, clinical validation, or policy input?
• Organisation type: do you need a university, research centre, SME, large industry player, NGO, or public authority?
• Geography: which countries are required for eligibility, and where do you need reach for impact and exploitation?
• Role: will the partner lead a work package, run pilots, or drive dissemination and exploitation?

Aim for balance as well as coverage. A winning consortium combines partners from various disciplines, ensures each partner has a unique role to avoid redundancy, and maintains a sensible geographical spread with a balance between profit and non-profit partners (PRIMA, How to build a winning consortium infoday, 16 February 2021). In practice, complementarity is what separates a functional consortium from a collection of logos.

Many coordinators find it helps to build a small core group first: two or three highly credible partners with whom you draft the scope, objectives, and rough project outline, then recruit the remaining partners around that core. The European Research Executive Agency (REA) advises choosing partners that can genuinely contribute to your goal rather than partners chosen for convenience (REA, How to build a successful consortium for a Horizon Europe project).

Where Do You Find EU Project Partners?

You find EU project partners through your existing network first, then through official EU tools including the Funding & Tenders Portal Partner Search Tool, CORDIS, and the Horizon Dashboard, and through National Contact Points, brokerage events, and the Enterprise Europe Network. Combining trusted contacts with systematic tool-based searches gives you both reliability and reach.

Start with people you know and trust

The best starting point is usually colleagues and peers with whom you already have direct or indirect links, because trust and a track record of delivery reduce implementation risk (UKRO, Horizon Europe Finding Partners and Building a Consortium factsheet, August 2024). Partners from previous projects, academic collaborators, and institutional networks form a reliable core.

Use the official EU partner search tools

The Partner Search Tool is a free European Commission facility on the Funding & Tenders Portal that lets you find organisations registered in the portal by keyword, past call topic, geography, or organisation type. Use it to identify entities that participated in, or expressed interest in, related calls (EURAXESS, Looking for partners to prepare a Horizon Europe proposal). Other essential resources include:

• CORDIS: the Commission's database of past and current EU-funded projects, useful for spotting organisations active in your field and the partners they worked with.
• The Horizon Dashboard: a visual overview of past and current projects, helpful for mapping who funds what and where (Euresearch, Partnering in Horizon Europe Collaborative Projects, July 2024).
• The Enterprise Europe Network (EEN): brokerage events and partner search services, with an event calendar for meeting potential partners face to face.

National Contact Points and thematic NCP networks also run partnering activities and can connect you with organisations in other countries. Many topic-specific partnerships, such as PRIMA, offer their own partnering tools for their calls (PRIMA, How to build a winning consortium infoday, 16 February 2021).

Register and validate every partner

All participants must be registered in the Participant Register and validated by the Central Validation Service by the time the grant is signed. Registration is mandatory for beneficiaries, affiliated entities, and associated partners; validation by the time of grant signature is mandatory for beneficiaries and affiliated entities (Funding & Tenders Portal Online Manual, Apply with partners or as individuals). Ask each prospective partner for their nine-digit Participant Identification Code (PIC) early, so you can confirm they are registered.

What Roles Exist Within an EU Consortium?

An EU consortium has a coordinator, beneficiaries, affiliated entities, and optionally associated partners, subcontractors, and other third parties. The coordinator is the central contact point for the granting authority and represents the consortium, while beneficiaries implement their part of the action and receive EU funding (HE AGA, Article 1.1). Understanding these roles helps you design a partnership that is both eligible and workable.

The table below summarises the key roles based on HE AGA Article 1.1 and the Funding & Tenders Portal Online Manual.

Coordinator

The coordinator must coordinate and manage the grant, including distributing payments received from the granting authority, and is the central contact point for the granting authority (HE AGA, Article 1.1; Article 22.2). All communication with the granting authority should in principle go through the coordinator (HE AGA, Article 3.1). The coordinator directly signs the Grant Agreement.

Beneficiaries

The other beneficiaries accede to the Grant Agreement by signing the Accession Form; only beneficiaries sign it (HE AGA, Article 1.1). Beneficiaries must collectively contribute to a smooth and successful implementation, comply with their own obligations, and support the coordinator (HE AGA, Article 3.1).

Affiliated entities

Affiliated entities are entities with a capital or legal link to a beneficiary that may participate in the action. Their funding arrangements are governed by AGA Article 8, which sets out the specific conditions under which they may receive EU funding. They do not sign the Grant Agreement or the Accession Form, but they must be registered in the Participant Register (registration is mandatory) and validated by the Central Validation Service by the time the grant is signed (HE AGA, Article 1.1; Funding & Tenders Portal Online Manual). Because affiliated entities are distinct from associated partners and beneficiaries, coordinators must identify them accurately from the outset to avoid registration bottlenecks at grant signature.

Associated partners

Associated partners are entities that implement action tasks but do not receive EU funding and do not sign the Grant Agreement. They perform tasks attributed to them in Annex 1 at their own cost, and they may not charge costs or contributions to the action (HE AGA, Article 9). Associated partners do not need a capital or legal link to any beneficiary, though they may have one, and the consortium remains responsible towards the granting authority for their work.

Subcontractors

Subcontractors and other third parties that contribute to the action may also be part of the consortium where the beneficiaries consider it useful (HE AGA, Article 1.1; Article 3.1). Subcontractors do not sign the Grant Agreement and do not receive EU funding directly; they are procured by beneficiaries to carry out specific tasks and are paid from the beneficiary's budget. It is generally recommended to involve all entities important for successful implementation, independently of their formal role in the grant (HE AGA, Article 3.1).

How Do You Formalise a Consortium With a Consortium Agreement?

You formalise a consortium through a consortium agreement: an internal, written agreement between the members that sets out their arrangements for implementing the project and administering the EU grant. It is mandatory for multi-beneficiary grants where required in the Data Sheet, and the Commission strongly recommends one in every case (HE AGA, Article 4; Article 4.1).

The consortium agreement is defined in the Annotated Grant Agreement as "an agreement between members of the consortium, to set out their internal arrangements for implementing the project and the administration of the EU grant." It is purely internal: it should not be submitted to the granting authority, and the granting authority is not a party to it and has no responsibility for it (HE AGA, Article 4.1). It must complement the Grant Agreement and must not contain any provision contrary to it, or to applicable EU, international, or national law (HE AGA, Article 4).

Timing matters. The agreement should in principle be negotiated and concluded before grant signature, so that each beneficiary signs the consortium agreement before signing the Accession Form. Leaving this until late in the process carries a serious risk: prolonged disagreement over IP ownership or decision-making clauses can jeopardise the action entirely (HE AGA, Article 4).

The agreement must be in writing and can take the form of a simple written agreement or another form, such as a notarial deed or the statutes of a separate legal entity. Its duration should at least cover the time until final payment, and a longer or open-ended duration is worth considering to cover post-payment issues such as exploitation of results, licensing, or audits (HE AGA, Article 4). For practical guidance, coordinators can refer to the Commission's "How to draw up your consortium agreement", which was developed for Horizon 2020 (MFF 2014-2020) but can also serve as inspiration for other EU programmes and the 2021-2027 framework (HE AGA, Article 4). The DESCA Model Consortium Agreement is another widely used reference that consortia adapt to their specific circumstances.

For the full regulatory text, see the HE Annotated Grant Agreement (AGA), the primary interpretive document for all Horizon Europe grant obligations.

What Should Coordinators Do in Practice?

Coordinators should start early, build a credible core, assign non-redundant roles, and lock down governance before submission. Starting on time is critical: rival consortia compete hard, and they may recruit your ideal partners first (PRIMA, How to build a winning consortium infoday, 16 February 2021). The sequence below gives you a concrete framework.

1. Read the Topic page conditions and confirm eligibility. Note the minimum and any topic-specific composition rules, then verify that your intended core meets the applicable country rule with at least one EU Member State partner.
2. Draft a one-page partner profile per gap. For each missing competency, specify the organisation type, target countries, and the work package or task the partner will own, following the job-description approach.
3. Search systematically. Run keyword and past-topic searches in the Partner Search Tool, cross-check active organisations on CORDIS, and attend relevant Enterprise Europe Network brokerage events.
4. Vet each candidate. Assess complementarity, delivery track record in previous EU-funded projects (as evidenced on CORDIS), financial viability as confirmed through Participant Register validation, and capacity to meet HE obligations. These factors map directly to the Quality and Efficiency of Implementation criterion that evaluators apply (Horizon Europe Work Programme General Annex D; Future Needs, 7 steps to find the right EU project partner).
5. Collect PICs and confirm registration. Ask every partner for their Participant Identification Code and confirm registration in the Participant Register so validation is not a bottleneck at grant signature. This applies to beneficiaries, affiliated entities, and associated partners alike.
6. Draft the consortium agreement in parallel with the proposal. Circulate a template covering governance bodies, decision-making, IP ownership and access rights, budget distribution, and conflict-resolution, aiming to conclude it before the Accession Forms are signed. Disagreements over IP and governance that are left unresolved until the grant preparation stage are a known source of delay and, in serious cases, can jeopardise the action itself (HE AGA, Article 4).

Consider a worked scenario. Suppose you coordinate a Cluster 5 energy proposal and, three weeks before the deadline, a pilot-site partner withdraws. Because you profiled roles in advance, you can identify a replacement from your CORDIS shortlist, confirm their PIC and validation status, reassign the pilot work package task in the Description of the Action (DoA, Annex 1 of the grant), and update the budget table without destabilising the rest of the consortium. If the composition change is needed after submission or grant signature, it would require a formal amendment to the Grant Agreement. Advance role mapping is what makes the pre-submission scenario recoverable without that step.

Remember that involving important entities as associated partners lets you bring in capability without adding funded beneficiaries, since associated partners implement tasks at their own cost (HE AGA, Article 9). This can strengthen impact and exploitation while keeping the funded consortium lean.

Conclusion and Outlook

Building a strong EU consortium is a strategic exercise, not a box-ticking task. Start from the call's eligibility rules, define precise partner profiles, source through your network and the official EU tools, assign clear and complementary roles, and formalise everything in a consortium agreement concluded before grant signature. Evaluators reward consortia that are cohesive, complementary, and demonstrably capable of delivering.

Horizon Europe continues to prioritise cross-border collaboration through its 2026-2027 work programmes (EURAXESS, Looking for partners to prepare a Horizon Europe proposal). Coordinators who invest early in the right partnership, and who treat the consortium agreement as a live governance instrument rather than a signing formality, position their proposals to score higher and their projects to run more smoothly. You can find currently open calls on the Funding & Tenders Portal Horizon Europe programme page.

Frequently Asked Questions

How many partners do you need for a Horizon Europe project?

For most Horizon Europe collaborative actions, at least three independent legal entities are required, each established in a different EU Member State or Associated Country, with at least one based in an EU Member State (UKRO factsheet, August 2024; HE AGA, Article 1.1). For co-funded partnership calls, the minimum drops to two entities from two different EU Member States or associated countries for multi-beneficiary projects. Many funded projects have more than the minimum; the right number depends on topic requirements, expected impacts, activities, and available budget. Always check the Topic page for call-specific conditions.

Where can I find partners for an EU project?

Start with your own trusted network, then use official EU tools: the Funding & Tenders Portal Partner Search Tool, CORDIS for past and current projects, and the Horizon Dashboard. National Contact Points and the Enterprise Europe Network (EEN) run brokerage events. The Partner Search Tool lets you filter registered organisations by keyword, past call topic, geography, or organisation type (EURAXESS, Looking for partners to prepare a Horizon Europe proposal).

What is the difference between a beneficiary, an affiliated entity, and an associated partner?

A beneficiary signs the Grant Agreement (via the Accession Form), implements action tasks, and receives EU funding. An affiliated entity has a capital or legal link to a beneficiary and may participate in the action; its funding arrangements are set out in AGA Article 8. It does not sign the Grant Agreement but must be registered in the Participant Register and validated before grant signature. An associated partner implements tasks attributed in Annex 1 but does not sign the Grant Agreement, participates at its own cost, and may not charge costs to the action (HE AGA, Article 9). Subcontractors may also contribute to the action; they are procured by beneficiaries and do not receive EU funding directly (HE AGA, Article 1.1).

Is a consortium agreement mandatory in Horizon Europe?

A consortium agreement is mandatory for multi-beneficiary grants when required in the Grant Agreement Data Sheet, and the Commission strongly recommends one in every case (HE AGA, Article 4). It is a purely internal, written agreement covering roles, decision-making, IP, and budget distribution. It should be concluded before grant signature, so each beneficiary signs it before signing the Accession Form. The DESCA Model Consortium Agreement is a widely used template coordinators can adapt.

Can third-country organisations join a Horizon Europe consortium?

Yes. Institutions from third countries can join most Horizon Europe calls as part of a consortium, but the three core partners must all come from EU Member States or Horizon Europe associated countries: specifically, at least one partner from an EU Member State and at least two additional partners from two other EU Member States or associated countries (EURAXESS, Looking for partners to prepare a Horizon Europe proposal). Eligibility for automatic EU funding for third-country entities is subject to specific conditions, so verify the rules on each individual call's Topic page.
