<P> Contestants that make it into the semi-finals by making it through the auditions and being chosen by the judges ( or , from series 8 , received the Golden Buzzer during their audition ) , perform once more before an audience and the judges , with their performance broadcast on live television . Until the tenth series , live episodes were broadcast from The Fountain Studios in Wembley , the same site used for The X Factor , but following its closure in 2016 , the show relocated its live episodes to Elstree Studios in 2017 , before moving to Hammersmith Apollo the following year . Like the Audition stage of the contest , each semi-finalist must attempt to impress by primarily conducting a new routine of their act within the same span of time ; the judges can still use a buzzer if they are displeased with a performance and can end it early if all the buzzers are used , along with giving a personal opinion about an act when the performance is over . Of the semi-finalists that take part , only two can progress into the final , which is determined by two different types of votes - a public phone vote , and a judges ' vote . </P>
