Open Access for REF 2029

These pages are designed to help UCL researchers understand the requirements of the open access policies for the 2029 Research Excellence Framework.

Making your paper eligible for REF 2029

Visit our step-by-step guide to making your paper eligible for REF 2029.

Open access and the REF

The UK REF exercise assesses the quality of research in UK Higher Education Institutions and informs the allocation of funding for research. An open access requirement was introduced for REF 2021 and continues for REF 2029. Only research papers meeting specific open access requirements are eligible for submission to the next REF. 

  • The original REF 2021 OA policy applies to journal articles and proceedings published until 31 December 2025 (date of first/online publication). 
  • The updated OA policy applies to journal articles and proceedings published from 01 January 2026.

Papers published as Gold/fully open access by the publisher, with a CC BY licence (e.g. through UCL’s transformative agreements or in a fully open access journal), comply with both policies. 

From January 2026, there are stricter requirements where the publication is not made open access on the publisher's webpage. The author must still upload their final accepted manuscript to RPS to be made open access in UCL's repository (Green open access). UCL is planning measures to ensure that the new requirements - which relate to licensing and permitted embargo periods - will be met when when authors upload their manuscripts. Details will be shared in due course.

Longform outputs are not in scope of the policy: monographs, book chapters and edited collections do not need to be open access in order to be submitted to REF 2029. UCL authors can currently apply for funding to cover the cost of publishing longform publications Gold open access, or may (where the publisher permits) be able to make their their publication Green open access.
