ITV in 2002, but this year it will be filmed at Gwrych Castle in Conwy as a result of the coronavirus pandemic.ITV has published a " Covid management plan" which details measures including the use of wearable buzzers, which will go off when crew members come too close to one another.Show bosses have also halved the number of on-site crew, with much work taking place remotely in London.There will also be "extremely limited" production access to both the celebrity contestants and hosts Ant McPartlin and Declan Donnelly.As they did when hosting reality TV show Britain's Got Talent, Ant and Dec have formed a close contact cohort.This means they can work together as long as they are tested every three days.
