Sir Tom will be joined on the panel on the series by Oscar-winning actress and singer Jennifer Hudson and rock star Gavin Rossdale.
Welsh singing veteran Sir Tom said: “I’m looking forward to returning to my big red chair on The Voice UK.
The Voice UK moved channels when ITV acquired the rights to it last year, after a five-series run on BBC One.
Sir Tom Jones will return to The Voice UK when the show makes its debut on ITV after he previously slammed the BBC for firing him from the line-up in 2015.
