The BBC One show started last weekend at 7PM, but will air earlier this month to ensure it starts before BGT on ITV.
The Britain's Got Talent 2013 start date was confirmed today as April 13, at 7PM.
The news saw BBC quickly shift The Voice back by 15 minutes to start at 6:45PM that weekend going forward.
It follows some less than impressive launch ratings for the second series of The Voice, with two million fewer viewers tuning in to the opening episode last month compared to last year.
A source claimed earlier this year that bosses at the Beeb were worried about potential clashes, saying: “There is a lot riding on The Voice this year. I needs to succeed to prove its critics wrong.”
Speaking about another clash between the two shows back in February, BGT boss Simon Cowell took pleasure in reminding the BBC who won last year’s battle.
“Everyone kind of predicted doom and gloom and then the word of mouth spreads, and in the end we beat them,” he said. “I don’t take anything for granted. We push these producers like crazy to try and make a better show than we did the year before, but it actually will rest on how good the talent is or how bad it is.”
However a BBC source hit back this week: “This is disappointing news for viewers and this clash could have been avoided by ITV. I am getting a sense of deja vu, last year ITV caused a clash by bringing the series forward a few weeks, this time they are scheduling the show earlier.
“It is TV viewers at home who lose out and this could easily be avoided. Many people will want to watch both shows so it makes no sense.”
