Filming of the series was originally planned for 2021, but with the COVID-19 pandemic in the United Kingdom having led to strict government restrictions on television production, many of the production team, including Simon Cowell, felt it would be wiser to postpone filming until conditions improved.
Filming eventually began in January 2022, with Cowell making his return as a judge for the programme following his accident during the previous series.
The fifteenth series was planned for production and broadcast in 2021, yet ITV, Thames and Syco Entertainment were concerned on how to safely conduct filming in the midst of new Government restrictions to combat the COVID-19 pandemic in the United Kingdom.
After initially deciding to postpone production until later in the year,[1] all involved parties agreed that they would not produce a new series until the following year, when Government restrictions would be eased and conditions surrounding the pandemic would be favourable for large-scale television production.
