If you’re writing a paper for publication, there are six main aspects you should consider to ensure it complies with your funder’s policy and is eligible for the next REF.
Check that your preferred journal’s open access options are compliant.
Use the SHERPA tools:
http://sherpa.ac.uk/fact for funder compliance
https://ref.sherpa.ac.uk for REF compliance
Or email the Library’s Open Access Team to ask.
UKRI accept both Gold and Green routes to open access, but if the Green route is taken, your article must be available immediately without embargo.
Horizon2020 requirements: The green route is acceptable as long as the embargo is under 6 months, or 12 months for social science research.
