Jeff was ill and unable to compete during the technical challenge and showstopper in episode 1. As a result, the judges decided that it was unfair to eliminate anyone in his absence.

Jeff left the show during the technical challenge in episode 2 after feeling unwell.

Illiyin's showstopper in episode 2 was evaluated without her, as she fainted at the end of the challenge and required medical attention.

Jeff fell ill during the technical challenge and as it was his second consecutive week falling ill, he withdrew from the show altogether.

Illiyin fainted at the end of the showstopper challenge. Since she was still able to complete the round, the judges continued with evaluating her bake, deeming her a candidate for elimination alongside Georgie and Hazel.

Episode 3: Bread The ten remaining bakers were asked to carry out three challenges. The Signature Challenge was to make twelve identical savoury buns which had to be from an enriched, yeast-based dough, but could be any flavour and any shape. The Technical Challenge let the bakers watch Paul Hollywood demonstrate the plaiting of seven strands of dough to form a wreath before they then had two and a half hours to repeat the exercise. The final Showstopper Challenge this week was to make a cornucopia, also called a 'horn of plenty', filled with at least two different types of bread.
