Horizon Europe Grant Agreement: The Clauses Every Coordinator Must Know

The Horizon Europe Model Grant Agreement (MGA) is the legally binding contract between the granting authority and your consortium. It defines the work, budget, duration, and the rights and obligations of every party. For a coordinator, four clauses matter most: who does what and how the consortium is bound together (Article 7), how money flows (Articles 21 and 22), and how you change the agreement once it is signed (Article 39). Get those right, and most day-to-day compliance follows.

The Grant Agreement rests on a corporate model used across all EU programmes under direct management, with Horizon-specific rules added through options in the text and in Annex 5. To interpret any clause in practice, you work from the Annotated Grant Agreement (AGA, v2.0, 01.04.2025), the Commission's official article-by-article guidance. Three earlier draft versions of the AGA (published 23.07.2021, 30.11.2021, and 01.04.2023) preceded the first non-draft publication; version 1.0 was published on 01.05.2024 and version 2.0 (01.04.2025) is the current authoritative text.

This article walks through the clauses that generate the most questions, and the most audit findings, for coordinators. Each section leads with the direct answer, then explains what it means when a partner drops out, a payment is late, or the work changes mid-project.

What Is the Horizon Europe Model Grant Agreement?

The Horizon Europe Model Grant Agreement is the standard contract template that sets out the rights, obligations, and terms and conditions each beneficiary must meet when implementing the action. Article 1 defines the subject of the agreement: the rights and obligations of each party and the terms and conditions of the grant. Article 3 states that the grant is awarded for the implementation of the action as described in Annex 1, the description of the action (DoA) (HE AGA v2.0, Article 3, p.32).

A grant under Horizon Europe is public funding in the form of a donation: a free, non-reimbursable contribution. As the AGA puts it plainly, the granting authority is not procuring your work, and your project is not "done for the European Commission" (HE AGA v2.0, Article 1, p.29). This distinction shapes liability and reporting. You are accountable for delivering the action as described, not for producing a deliverable a client ordered.

The agreement is prepared during grant preparation together with your EU project officer, who sets the framework for deliverables, reporting, and payments (HE Work Programme 2025, General Annexes, Section G, p.2). The European Research Executive Agency (REA) confirms on its grants and reporting page that for each project there is a project officer who accompanies the consortium throughout implementation, and that the project officer is the coordinator's main contact for any matters regarding the grant agreement and reporting. The complete text of the applicable model is published on the topic page of the Funding & Tenders Portal, alongside the rest of the call documentation.

Three types of Horizon Europe MGA

Horizon Europe uses three types of Model Grant Agreement. They differ mainly by the form of funding and the specific requirements of the projects for which they are used. The unit cost version, for example, contains provisions in Annex 5 that apply specifically to Marie Skłodowska-Curie Actions (MSCA) and ERA Fellowships, addressing in particular the relationship between the beneficiary and the researcher. If you coordinate an MSCA or ERC action, check which MGA type your call specifies and review Annex 5 carefully. It carries programme-specific rules you will not find in the main body of the agreement.

Where to find the definitions

Article 2 collects the terms that recur across the whole agreement, covering types of participants such as beneficiaries and affiliated entities, budget cost categories such as subcontracting, and legal concepts such as grave professional misconduct (HE AGA v2.0, Article 1 commentary, p.1). Less common terms are defined inside the specific article that uses them, and in Annex 5 where applicable, so always check both.

What Annex 5 contains

Annex 5 sets out the Horizon-specific programme options in full. If you are looking for intellectual property rules, Article 16 gives you the framework, but Article 16.4 directs you to Annex 5 for further detail: you may find nearly eight pages of additional provisions there, depending on your action type. Annex 5 also carries open science obligations, including the additional dissemination and communication provisions that apply to all grants awarded under the Horizon Europe Work Programme 2025 (HE Work Programme 2025, General Annexes, Section G, p.2; HE AGA v2.0, Article 1 commentary, p.1). Treat Annex 5 as part of your working agreement, not a supplementary document.

Who Signs the Grant Agreement and What Is the Coordinator's Role?

The coordinator signs the Grant Agreement directly; every other beneficiary joins by signing the Accession Form. The coordinator is the single beneficiary that acts as central contact point for the granting authority and represents the consortium. Affiliated entities, associated partners, and subcontractors do not sign the Accession Form, and any later amendment is signed by the coordinator on behalf of all beneficiaries (HE AGA v2.0, Article 1.1, p.4).

The coordinator is the beneficiary that coordinates and manages the grant, distributes payments, and serves as the interface with the granting authority. Under Article 7, the coordinator must request and review documents before passing them on, submit deliverables and reports, and distribute payments received to the other beneficiaries without unjustified delay. Under Article 23, the coordinator must also submit pre-financing guarantees to the granting authority, if required (HE AGA v2.0, Article 7, p.1; HE AGA v2.0, Article 23.1).

Here is the clause coordinators most often overlook: these core tasks cannot be delegated or subcontracted to any other beneficiary or third party, including affiliated entities (HE AGA v2.0, Article 7, p.1). There are narrow exceptions. Public-body coordinators may delegate payment-administration tasks to entities with "authorisation to administer" that they control, and sole beneficiaries such as European research infrastructure consortia (ERICs) may delegate to one of their members. In both cases, the coordinator keeps sole responsibility for compliance.

In practice, you cannot outsource your financial-distribution or reporting duties to a professional management company as if it were the beneficiary. You can hire support to run those processes, but the legal responsibility stays with your organisation. A common difficulty: coordinators underestimate this administrative load at proposal stage and under-budget the project management work package.

What Does Joint Responsibility Mean If a Partner Leaves?

Beneficiaries are jointly responsible for the technical implementation of the whole action. If one beneficiary leaves for any reason, the remaining partners must carry out the action as set out in Annex 1, including the defaulting partner's tasks, and they must do so without any additional funding (HE AGA v2.0, Article 7, p.147). The Grant Agreement then has to be amended to redistribute tasks, terminate the departing beneficiary, or add a new one under Article 39.

The AGA gives a concrete example. Beneficiaries A, B, and C sign a three-year Grant Agreement. One year in, C goes bankrupt. A and B remain fully responsible for implementing the entire action, including C's tasks, and must either take over that work themselves or bring in a replacement so the action is completed as described in Annex 1 (HE AGA v2.0, Article 7, p.147).

Financial responsibility works differently from technical responsibility. Each beneficiary is in principle responsible for the sound financial management of its own part of the grant. Horizon Europe operates the Mutual Insurance Mechanism (MIM), which is a fund-based guarantee mechanism covering the financial risk from defaulting beneficiaries. Under MIM, which applies to Horizon Europe but not to all EU programmes, each beneficiary's financial liability is in principle limited to its own debt: the MIM fund can step in to cover a defaulting partner's amounts, and the granting authority then recovers them from the defaulting beneficiary rather than passing the exposure to the coordinator (HE AGA v2.0, Article 22.1). This means the coordinator is not left personally liable for recovering a partner's undue amounts in the way it would be under non-MIM programmes. At beneficiary termination, the partner concerned must repay any undue amounts, and the granting authority informs them of that obligation (HE AGA v2.0, Article 7, p.147).

Why Does Partner Withdrawal Affect Your Budget Planning?

Because the remaining partners absorb the departing partner's work without extra money, a mid-project withdrawal is a budget and staffing problem, not just a legal one. If a partner holding a critical technical task withdraws in Month 18 of a 36-month project, convene the general assembly, identify who has the capacity and competence to absorb the tasks, and open a Grant Agreement amendment before the next reporting period closes, so the redistributed effort is reflected in the person-months you claim.

How Do Payments and Reporting Work Under the Grant Agreement?

Under Articles 21 and 22, beneficiaries prepare periodic reports on work progress and costs collectively, and the coordinator submits them and the payment requests through the Grant Management System on the Funding & Tenders Portal. The coordinator must then distribute payments received to partners without unjustified delay. Article 21 also covers continuous reporting on milestones and deliverables throughout the project (Horizon Europe Model Grant Agreement, Article 21).

The payment clauses also protect the consortium. If the granting authority pays late, beyond the payment deadlines, it automatically pays late-payment interest for the overdue period. Three exceptions apply under Article 22.5.1: when all beneficiaries are Member States or bodies acting on their behalf; when the payment deadline is formally suspended; or when the interest amount is EUR 200 or less, in which case it is paid only on request from the coordinator (HE AGA v2.0, Article 22.5.1, p.247). For amounts above EUR 200, payment is automatic. Late-payment interest is paid separately, on top of the grant amounts.

That protection runs both ways. If the coordinator breaches its Article 22 obligations, for example by failing to distribute payments or report on their distribution, the grant may be reduced under Article 29, and the grant or the coordinator may be terminated under Article 32 (HE AGA v2.0, Article 22.5.2, p.247). Beneficiaries can also owe late-payment interest if they are slow to repay undue amounts during a recovery.

Record-keeping underpins all of this. Article 20 requires every beneficiary to keep records and supporting documents confirming proper use and the costs claimed throughout the project. Separately, under the Horizon Europe Work Programme 2025, beneficiaries must, up to 4 years after the end of the action, inform the granting authority if results could reasonably be expected to contribute to European or international standards, this is a notification obligation, not a general record-retention period (HE Work Programme 2025, General Annexes, p.33). Those records are exactly what auditors examine first. Reports must be prepared by the consortium collectively but submitted by the coordinator through the EU Funding & Tenders Portal Grant Management System.

When Is a Consortium Agreement Required and What Should It Cover?

Beneficiaries must have internal arrangements governing how the consortium operates and coordinates, so the action is implemented properly. Where the granting authority requires it, as indicated in the Data Sheet at Point 1, those arrangements must be set out in a written consortium agreement (CA) between the beneficiaries, and the CA must not contain any provision contrary to the Grant Agreement (HE AGA v2.0, Article 7, p.1).

The consortium agreement is the internal contract among beneficiaries that fills the gaps the Grant Agreement deliberately leaves to the partners. Per the AGA, it typically covers:

• the internal organisation of the consortium and the management of access to the Portal;
• different distribution keys for payments and financial responsibilities in case of recoveries;
• additional rules on rights and obligations related to background and results under Article 16;
• settlement of internal disputes; and
• liability, indemnification, and confidentiality arrangements between beneficiaries (HE AGA v2.0, Article 7, p.1).

Where the granting authority indicates that a consortium agreement is required in the Data Sheet at Point 1, this applies to the great majority of collaborative Research and Innovation Actions under Horizon Europe. In those cases, the internal arrangements must be in place to ensure the action is implemented properly from the outset (HE AGA v2.0, Article 7, p.1). Drafting and signing the CA is not formally the coordinator's obligation under the MGA, but coordinators are almost always expected to lead the process, because they carry the interface with the granting authority (Enspire Science, "What it means to be a Horizon Europe Project Coordinator").

Many coordinators find the intellectual property provisions the most negotiated part of the CA. Article 16 of the MGA sets out the framework for background, results, and access rights: background is existing knowledge a beneficiary brings to the project, while results are new knowledge generated during it. The CA must specify who owns jointly generated results, on what terms partners can access each other's background for project implementation and exploitation, and how access rights are exercised after the project ends. The operational detail of those arrangements is where the CA does the real work. Widely used templates such as DESCA, developed by the DESCA Core Group (a consortium of European research organisations), give consortia a starting point, though you still need to tailor the IP and payment-distribution annexes to your project.

How Do You Change the Grant Agreement After Signature?

Any change to the Grant Agreement or its annexes must go through a formal amendment recorded directly in the Grant Management System on the Funding & Tenders Portal. The coordinator initiates and signs amendments on behalf of the consortium (HE AGA v2.0, Article 1.1, p.4). Amendments are the mechanism for redistributing tasks, changing the budget, adding or removing beneficiaries, or adjusting the duration set in Article 4.

Common triggers include a beneficiary leaving or being replaced, a significant reallocation of the budget across partners or cost categories, a change of coordinator, and an extension of the project duration. Any such change must be documented in a formal amendment in the system, not simply agreed by email among partners (HE AGA v2.0, Article 39; Horizon Europe Programme Guide).

In practice, consortium changes involving beneficiary termination and redistribution of tasks typically require several weeks to prepare, negotiate with your project officer, and finalise in the Portal. Budget-neutral, administrative changes are far quicker than those that touch the science or the partners. Plan the timeline so an amendment is submitted well before the reporting period in which it needs to take effect.

Which Rules Apply to Pillar-Assessed Participants?

If a beneficiary has passed a pillar assessment, it may apply its own internal procedures for purchases, subcontracting, and financial support, but not for matters that would breach equal treatment or call the award decision into question. The core coordinator clauses covered in this article, eligibility under Article 6, consortium roles under Articles 7 to 9, and payment, reporting, and amendments under Articles 21, 22, and 39, apply to everyone, regardless of any pillar assessment (HE AGA v2.0, Article 10.1, p.172).

Which Articles Matter Most for Day-to-Day Coordination?

The table below maps the articles most relevant to your day-to-day coordination duties. Use it as a quick reference when preparing for reporting cycles, amendments, or consortium changes.

What Should Coordinators Do Before and During Implementation?

Effective coordination under the MGA means turning these clauses into concrete actions before and during your project. The five steps below cover the obligations that most often generate audit findings or consortium disputes. Treat them as a minimum baseline, not an exhaustive list.

• Map roles against Article 7 before the kick-off meeting. Confirm in writing which tasks are the coordinator's non-delegable duties (payment distribution, reporting, deliverable submission) and which can be supported by external help, so no partner assumes the coordinator can hand off its legal responsibilities. Also confirm whether your grant requires a pre-financing guarantee under Article 23.1, as this must be submitted to the granting authority before the first pre-financing payment is released.
• Build a partner-withdrawal contingency into the consortium agreement. Because remaining partners must absorb a departing partner's tasks without extra funding (HE AGA v2.0, Article 7, p.147), agree in advance which beneficiaries could take over which critical tasks, and record it in the CA.
• Set an internal reporting calendar that precedes each official deadline. Give partners an internal cut-off ahead of each periodic report submission through the Grant Management System's periodic reporting module, so you can review quality and completeness as Article 7 requires before the coordinator submits through the Portal.
• Open amendments early. For any consortium change, start the amendment in the Portal well ahead of the reporting period it affects, and involve your project officer from the European Research Executive Agency at the outset.
• Keep Article 20 records audit-ready from day one. Ensure every beneficiary maintains supporting documents for costs claimed throughout the project, not just before a reporting deadline. Additionally, under the Horizon Europe Work Programme 2025, beneficiaries carry a separate obligation to notify the granting authority within 4 years after the end of the action if results could contribute to European or international standards (HE Work Programme 2025, General Annexes, p.33).

Read these clauses alongside your practical coordination workflow. Our guidance on Horizon Europe project management tools and best practices shows how to operationalise the reporting and amendment cycles the MGA sets out. The Horizon Europe Programme Guide and the EU Funding & Tenders Portal Online Manual on grant management are the other two reference points you should keep open throughout implementation.

Conclusion and Outlook

The Horizon Europe Model Grant Agreement concentrates a coordinator's obligations in a small number of high-stakes clauses. Article 7 defines your non-delegable role and the consortium's joint technical responsibility. Article 23 governs pre-financing guarantees. Articles 21 and 22 govern reporting and payment flows, including late-payment interest: the granting authority pays this automatically for amounts above EUR 200 under Article 22.5.1, while amounts of EUR 200 or less are paid only on request from the coordinator. Article 39 controls how you amend the agreement when the project inevitably changes. The consortium agreement fills the internal gaps, especially on IP and payment distribution.

Because the MGA rests on a corporate model shared across EU programmes and updated regularly, the safest practice is to work from the current Annotated Grant Agreement (AGA v2.0, 01.04.2025, current as of publication) and the specific options activated in your own agreement and Annex 5. Keep your project officer close, treat every change as a formal amendment, and make sure every beneficiary understands that joint responsibility is not a formality. Do that, and the Grant Agreement becomes a management tool rather than a compliance risk.

Frequently Asked Questions

What is Annex 1 of the Horizon Europe Grant Agreement?

Annex 1 is the description of the action (DoA), the technical part of your proposal converted into a binding annex of the Grant Agreement. Under Article 3 of the MGA, the grant is awarded specifically to implement the action as described in Annex 1. If a partner leaves, the remaining beneficiaries must still deliver everything set out in Annex 1, including the departing partner's tasks.

Can a coordinator delegate its tasks to a management company?

No. Under Article 7 of the Horizon Europe MGA, the coordinator cannot delegate or subcontract its core tasks, such as distributing payments, submitting reports and deliverables, to any other beneficiary or third party, including affiliated entities. Narrow exceptions exist for public-body coordinators and sole beneficiaries such as ERICs, but even then the coordinator retains sole responsibility for compliance (HE AGA v2.0, Article 7, p.1). Pre-financing guarantees are a separate obligation governed by Article 23.1.

When does the granting authority pay late-payment interest?

If the granting authority pays beyond the payment deadlines, it automatically pays late-payment interest on top of the grant, per Article 22.5.1 of the MGA. Exceptions apply when all beneficiaries are Member States, when the payment deadline is formally suspended, or when the interest is EUR 200 or less, in which case it is paid only on request from the coordinator. For amounts above EUR 200, payment is automatic (HE AGA v2.0, Article 22.5.1, p.247).

Is a consortium agreement mandatory in Horizon Europe?

A consortium agreement is required whenever the granting authority indicates so in the Data Sheet at Point 1, which applies to the great majority of collaborative Horizon Europe actions. The internal arrangements must not contradict the Grant Agreement (HE AGA v2.0, Article 7, p.1). The consortium agreement typically covers payment distribution keys, IP rules under Article 16, dispute settlement, and liability arrangements between beneficiaries.

How do you change a Horizon Europe Grant Agreement after signing?

Any change must be made through a formal amendment recorded in the Grant Management System on the Funding & Tenders Portal, initiated and signed by the coordinator on behalf of the consortium under Article 39 (HE AGA v2.0, Article 1.1, p.4). Common triggers include a partner leaving, budget reallocation, a change of coordinator, or a duration extension. Consortium changes involving beneficiary termination typically require several weeks, so open the amendment before the reporting period it affects.
