The Withdrawal Agreement means that the UK can continue to participate in EU programmes, including Horizon 2020, that are financed by the 2014-2020 Multiannual Financial Framework (MFF) until their closure (i.e. for the lifetime of grants). UK participants will continue to receive EU grant funding for the lifetime of individual Horizon 2020 projects, including projects finishing after the transition period ends at the end of 2020.

UK scientists, researchers and businesses can continue to participate in and lead Horizon 2020 projects and apply for Horizon 2020 grant funding. The vast majority of Horizon 2020 projects will be able to continue as before during the transition period and beyond. This includes ERC, MSCA, and the EIC Accelerator. However, for the latter, UK entities are now only eligible for the grant element of the programme, meaning they cannot apply for equity support.

A very limited number of UK Horizon 2020 projects, which involve access to security-related sensitive information restricted for EU Member States, may be unable to continue after EU Exit in their current form. The government expects the European Commission to inform participants if this is the case.
