Extension of the UK's Horizon Europe guarantee
Successful UK applicants whose projects are invited for grant preparation while the UK is not yet associated to Horizon Europe can apply for the UK's replacement funding. The UK will then reimburse the project costs budgeted for the UK institution for the entire lifetime of the project. A prerequisite for funding from the "Guarantee" is that the UK partner is listed as a "Beneficiary" in the project proposal and applies for funding from Horizon Europe. Further information can be found here and here.
