The European Commission has adopted the 5th list of Projects of Common Interest (PCIs), including 98 key cross-border energy infrastructure projects. However, due to the exit of the United Kingdom from the European Union, projects originating in the UK are no longer eligible for PCI status. Therefore, although GridLink has been designated as a PCI since 2017 on the 3rd List and 4th List, it does not appear on the 5th List.

GridLink remains a critical part of the future integration of the European energy system which will bring positive security of supply, climate change and economic benefits. Whilst PCI status is a welcome recognition of the project, the change is due solely to the new relationship between the United Kingdom and European Union and it does not change the importance of the benefits that GridLink offers to France, the UK and the European Union.
