The UK agreed a deal to associate to Horizon Europe on 7 September 2023. UK researchers can now apply for Horizon Europe funding, certain that all successful UK applicants will be covered through the UK’s association (or through the guarantee) for the remainder of the programme.

The guarantee funding will be delivered through UK Research and Innovation. All calls in Work Programme 2024 will be covered by association, and the UK guarantee scheme will be extended to cover all calls under Work Programme 2023.

This publication provides guidance on:

  • eligibility for the guarantee scheme
  • scope of the scheme
  • how to apply
