The first episode to be broadcast on Channel 4 received an overnight viewing figure of 6.5 million, which is the channel's highest viewing figure since the opening ceremony for the 2012 Paralympics, but down from the 10 million obtained in the previous series on BBC One. The overnight viewing figure for the final was 7.7 million (8.9 million at its peak), lower than the 14 million for the equivalent episode on BBC One in 2016.
