Following open auditions held the previous year between October and December, the Judges' audition took place between January and February 2017, within
Blackpool, London,
Birmingham and
Salford. Along with discontinuing the use of the Public wildcard format, production staff changed the rules to suspend the use of the Judges' vote – the change meant that the voting system would be purely conducted by a public vote, with the semi-finalists receiving the highest and second-highest tally of votes respectively automatically securing a place in the live final. This change in format was not announced until 27 May 2017; each received a golden buzzer during their auditions – with eight appearing in each one – returning to the original arrangement before the sixth series – and eleven of these acts making it into the live final; the wildcard act chosen by the judges was Sarah Ikumu, after she placed 3rd in the public vote in the third semi-final.
