The record finished two places above global pop icon Justin Bieber’s latest hit Hold On.
Craig tweeted: “Thank you so much everyone who has streamed or downloaded Come Waste My Time.
“LET’S GOOOOOOO.”
Craig had already made history on The Voice when Come Waste My Time became the best-performing self-written winner’s single and reached the top of the UK iTunes chart.
Praising Scottish fans after winning the live final on March 20, he said: “I just want to say thank you very much because without your support I wouldn’t be here.”
