Open Access & Institutional Repository: Horizon 2020/Horizon Europe

Open science requirements are embedded in your European Research Council grant agreement and depend on the Framework Programme (and in some cases, the ERC call) under which you obtained funding. 

We do not hold any central funding for Horizon or ERC, but if you have any questions please contact us:


Horizon 2020 (2014-2020)

For all publications you must ensure that your publication is deposited in a suitable repository of your choice immediately upon publication.

You can publish open access in any journal offering an open access option: publishing fees (including open access costs, but also page charges or colour charges) are eligible costs if incurred during the lifetime of your project and in line with the provisions in your grant agreement.

Use our journal check tool to see if a specific journal is included in our 'no cost to the author' open access publisher agreements - these are open to all University of Southampton corresponding authors, regardless of funder.

If your chosen journal does not offer an open access option:

  • you can make the Author Accepted Manuscript version of your article (called the final peer-reviewed manuscript by Horizon) available from a repository (eg deposit into Pure to display in ePrints Soton), providing the publisher does not set an embargo exceeding 6 months for LS* or PE*, or 12 months for SH*. You can check journal-specific embargo periods using Sherpa Romeo, or email for guidance.
  • Publishing fees (e.g. page charges, colour charges) are eligible costs if incurred during the lifetime of your project and in line with the provisions in your grant agreement.

*PE = Physical Sciences and Engineering, LS = Life Sciences, SH = Social Sciences and Humanities


Horizon Europe

Fully open access journals: costs are eligible for reimbursement as with Horizon 2020

Hybrid journals:

  • check if your chosen journal is included in a UoS publisher agreement which means there is no additional open access fee to pay. If the journal is not included, you cannot pay from your grant. 
  • if your chosen journal is not included in one of our publisher agreements and the publisher version of the article will be behind a paywall, Horizon Europe expects you to use the prior assignment of rights which allows the Author Accepted Manuscript (called the final peer-reviewed manuscript by Horizon Europe) to be made openly available from an institutional repository with no publisher-mandated embargo. You should assign your own CC BY licence to the final peer-reviewed manuscript by including the following wording in the funder acknowledgements section: 
    • This work was funded by the Εuropean Union under the Horizon Europe grant [grant number]. As set out in the Grant Agreement, beneficiaries must ensure that at the latest at the time of publication, open access is provided via a trusted repository to the published version or the final peer-reviewed manuscript accepted for publication under the latest available version of the Creative Commons Attribution International Public Licence (CC BY) or a licence with equivalent rights”.
    • Create a record in Pure and upload your final peer-reviewed manuscript

Horizon 2020: open access requirements after the end of your project  

Horizon 2020 open access obligations for peer-reviewed scientific publications extends beyond the end of your ERC-funded project. That means that even after your project ends, all publications that are related to project results funded by the ERC, will need to acknowledge ERC funding, and peer-reviewed publications will need to be made available through open access.
