The European Commission and the UK Government have concluded negotiations and reached an agreement in principle on the association of the UK to Horizon Europe.
UK researchers will be able to fully participate in the Horizon Europe programme on the same terms as researchers from other associated countries, including leading consortia, from the 2024 Work Programmes and onwards – including any 2024 calls opening this year. For calls from the 2023 Work Programmes, the European Commission will continue to administer transitional arrangements and the UK will continue to provide funding under the UK Guarantee. UK and EU scientists and researchers can have confidence in continuing long-term partnerships with their counterparts.
You can find the agreement made by UK Government and EC including not only for Horizon Europe but also Copernicus via link.
