Eurovision commentator Graham Norton will again be hosting the hunt for the act to represent the UK.
"Here's to all the usual fun, glamour, and madness of Eurovision," he said.
Performing live in the studio, the Eurovision hopefuls will be out this time to impress Pete Waterman – who's producing the UK's entry with long-time collaborator Mike Stock – plus a specially-selected panel.
Waterman said: "So far we've got the song and we've got six acts – now all we're waiting for is the public to get behind the search for the UK entry and then we can really get to work."
