Izzie has been played by four actresses since her onscreen arrival; Jasmin and Nicole Parkinson between 2008 and 2011, Maizey Corbett in 2012, and Bethan Moore from 2018 to 2022.

Her storylines in the programme have included being left in the Mill Health Centre as a baby, being kidnapped, her feud with Zara Carmichael (Elisabeth Dermot Walsh), becoming an environmental activist, coming out as pansexual and being the victim of online trolling.

When Moore was cast in the role, her age meant that Izzie could be given more mature storylines and she later received a nomination for the British Soap Award for Best Newcomer in 2019.

[9] Izzie takes half-brother Joe Granger Carmichael (Oliver Falconer) out for the day to make Zara and Daniel worry that the pair of them have gone missing.

[14] While staying with Daniel during half term, she sees netting hung across a tree in a car park and researches its purpose.

[16] She begins living with Daniel and Zara on a permanent basis and starts at the local school, but after online trolling and new boyfriend Lee Blackwell (Kieran Boon) cheating on her, she decides she wants to return to Lisa's house.
