Horizon Europe Work Programme 2026-2027 keeps the core open science mandate intact — immediate open access, FAIR data and a Data Management Plan for every project that produces data — while cutting call topics by 35%, expanding lump-sum funding to roughly half of all calls, and introducing new cross-cluster “horizontal calls”. For grant offices, the compliance clauses have not moved; the surrounding administrative machinery has.
The Horizon Europe Work Programme 2026-2027 is the European Commission’s final two-year implementation plan for the 2021-2027 Horizon Europe framework, published in December 2025 and covering all funding calls, budgets and eligibility rules through the end of the programme.

What changed in the Horizon Europe Work Programme 2026-2027?
The European Commission adopted the Horizon Europe Work Programme 2026-2027 on 12 December 2025, according to the European Health and Digital Executive Agency (HaDEA). The Commission committed over €14 billion across the 2026 and 2027 calls, spanning all three Pillars, the Missions, Widening Participation and Strengthening the European Research Area (WIDERA), and the New European Bauhaus Facility, as confirmed by Innovate UK Business Connect’s summary of the published documents.
The headline structural change is scale: the Commission’s General Introduction to the 2026-2027 Work Programme states that the number of topics across Pillar 2’s collaborative research Clusters was cut by 35% compared with the 2023-2024 Work Programme, a reduction also reported independently by Science|Business and EMDESK. Fewer, broader topics replace the previous highly prescriptive call texts.
| Dimension | Work Programme 2023-2025 | Work Programme 2026-2027 |
|---|---|---|
| Pillar 2 call topics | Baseline count | 35% fewer topics |
| Lump-sum funding share | Partial, growing | Approx. 50% of all calls |
| Open access mandate | Immediate OA, CC BY, no embargo | Unchanged |
| FAIR data / DMP requirement | Mandatory; “as open as possible, as closed as necessary” | Unchanged; EOSC integration reinforced |
| Cross-cluster “horizontal calls” | Not used | Introduced (e.g. Clean Industrial Deal, AI in science) |
| Committed budget signalled | — | Over €14 billion |
Open access to publications: what’s the same, what’s different
Nothing has changed in the core publication mandate. Under the Horizon Europe Model Grant Agreement, beneficiaries must ensure immediate open access to peer-reviewed publications reporting funded results, with no embargo period, deposit in a trusted repository, and a licence — typically Creative Commons Attribution (CC BY) or equivalent — that permits reuse, redistribution and text and data mining.
What grant offices should actually re-check is the supporting metadata clause, not the licence clause. The 2026-2027 General Annexes continue to require full bibliographic metadata and persistent identifiers (DOI, ORCID iD, ROR) on every deposited publication. Institutions that let repository metadata quality slip during the 2023-2025 cycle should treat the new Work Programme as a trigger to re-audit templates, not assume automatic carry-over.
- Confirm the trusted-repository and CC BY licence clause wording in your institutional agreement template matches the 2026-2027 General Annexes text
- Update publication-metadata forms to capture DOI, ORCID iD and ROR identifiers consistently
- Re-brief researchers that “no embargo” still means no embargo, even for monographs and long-form outputs
- Flag any project bidding into a new horizontal call for additional cross-cluster reporting fields
FAIR data, Data Management Plans and the EOSC push
The FAIR data obligation is also unchanged in substance: research data generated or collected under a funded grant must be Findable, Accessible, Interoperable and Reusable, and every applicable project must maintain a Data Management Plan (DMP) that is created early and updated across the project lifecycle. The principle “as open as possible, as closed as necessary” continues to govern the balance between openness and legitimate restriction — intellectual property, personal data and security exceptions still apply, but even restricted datasets must carry FAIR, openly accessible metadata.
What is new is emphasis, not obligation. Work Programme documentation for the Missions strand explicitly references infrastructures “federated under the European Open Science Cloud (EOSC)”, and the 2026-2027 cycle leans further into EOSC as the delivery mechanism for FAIR compliance — pushing project consortia towards EOSC-compatible repositories and machine-actionable metadata rather than institution-specific solutions. Grant offices whose DMP templates still point researchers to generic “any FAIR repository” language should update guidance to name EOSC-aligned options explicitly.
Structured contributor metadata is part of the same compliance chain: publications reporting Horizon Europe-funded work increasingly carry standardised role disclosures. CASRAI originated the CRediT contributor role taxonomy in 2014, and the standard is now stewarded by NISO as ANSI/NISO Z39.104-2022 — grant offices building publication-metadata checklists can treat CRediT-style role tagging as a practical way to strengthen the bibliographic metadata clause without waiting for a funder mandate to force it.
Structural and procedural changes that affect compliance workflows
Three procedural shifts in the 2026-2027 Work Programme indirectly affect how open science obligations get delivered, even though the obligations themselves are stable.
- Lump-sum funding expansion. EMDESK’s analysis, citing Science|Business reporting on the final Work Programme text, puts lump-sum funding at roughly 50% of all 2026-2027 calls — up sharply from the partial rollout in 2023-2025. Lump-sum grants change how compliance is verified, since cost reporting is replaced by milestone and deliverable verification, which shifts open-access and DMP checks toward deliverable sign-off rather than cost-claim audit.
- Horizontal calls. New cross-cluster calls address themes such as the Clean Industrial Deal and AI in science, spanning multiple Clusters within Pillar 2. These calls typically generate larger, more heterogeneous datasets, making FAIR data planning and interoperable metadata schemas more operationally important than under single-Cluster calls.
- Broader, less prescriptive topics. With 35% fewer topics, each call description covers more ground, meaning the same open-access and data clauses now apply across a wider range of project types per topic — grant offices should not assume a topic’s compliance profile is self-evident from a shorter call text.
Grant office FAQs and what happens next
When did the Horizon Europe Work Programme 2026-2027 take effect?
The European Commission adopted the Horizon Europe Work Programme 2026-2027 on 12 December 2025, per HaDEA’s official announcement, opening the programme’s final two-year cycle. Most single-stage call deadlines fall in September or October 2026, though some Clusters open earlier, with deadlines in March or April 2026.
Is open access still mandatory under Horizon Europe 2026-2027?
Yes. The 2026-2027 Work Programme retains the immediate open access mandate for peer-reviewed publications: no embargo, deposit in a trusted repository, a CC BY (or equivalent) licence, and complete bibliographic metadata with persistent identifiers. Grant offices should verify these clauses remain unchanged in institutional agreement templates.
What is the FAIR data requirement in Horizon Europe 2026-2027?
FAIR data means research data must be Findable, Accessible, Interoperable and Reusable, with a Data Management Plan required for projects that generate or collect data. “As open as possible, as closed as necessary” continues to apply, and metadata must remain FAIR even when underlying data is restricted.
How many fewer call topics are there in the 2026-2027 Work Programme?
According to the Commission’s General Introduction, Pillar 2’s collaborative research Clusters saw a 35% reduction in the number of topics compared with the 2023-2024 Work Programme, consolidating funding into broader, less prescriptive topic descriptions.
None of this changes the substance of what a research office signs up to when it accepts Horizon Europe funding: immediate open access, FAIR-managed data, and a live Data Management Plan remain non-negotiable. What has changed is the operating environment around those obligations — fewer but broader topics, half of all calls running on lump sums, and new cross-cluster calls that will generate messier, larger datasets than before. Institutions that treat the 2026-2027 Work Programme as a compliance-template refresh, not just a new set of calls to bid into, will spend less time firefighting metadata and DMP queries once projects are underway.
