Party lists in the 2019 European Parliament election in the United Kingdom

The 2019 European Parliament election for the election of the delegation from the United Kingdom was held on 23 May 2019. These were the last elections to the European Parliament to be held before Brexit.

Only constituencies in Great Britain used party-list proportional representation, as in Northern Ireland the single transferable vote system is used.

On 8 February 2019, party leader Nigel Farage stated he would stand as a candidate for the party in any potential future European Parliament elections contested in the United Kingdom. MEPs Steven Woolfe and Nathan Gill, also formerly of UKIP, stated that they would also stand for the party.

None of the Change UK candidates won any seats.

London
Ali Sadjady Naiery, a mixed martial arts fighter and former Conservative Party candidate for Ealing Borough Council, was originally placed sixth on Change UK's London list, but withdrew and was replaced after he was found to have made a tweet saying that Romanian pickpockets on the London Underground made him want Brexit.
