On 26 January 2021, World Snooker Tour announced that the Welsh Open would become the first event that season to be played outside the Marshall Arena, at the Celtic Manor Resort in Newport. This was made possible due to a Covid-bubble being able to be created with similar on-site accommodation facilities, meaning players were able to stay within the bubble while playing in the event. Later in the season, World Snooker confirmed that the 2021 Tour Championship event would be played at Celtic Manor as the final event of the season prior to the World Championship at the Crucible Theatre.
