But it wasn't all those claims of a fix that were being looked into, rather the obvious F-bomb that was dropped during one of the episodes.
A total of 6 viewers made official complaints about October 23's show following the language.
Finalist Gifty Louise shouted the expletive in a live episode as the elimination results were announced.
In the episode, Dermot O'Leary began as usual by announcing the trio of acts in the danger zone.
First to be called safe was Samantha Lavery, prompting Gifty to shout "F**king told you!", which was caught on one of the many microphones in the studio.
Host Dermot was quick to issue an on air apology over the language, which aired before the 9PM watershed.
"You may have just heard some inappropriate language, we deeply apologise," Dermot said to cameras. “As you can imagine tensions are high.”
After the results show yesterday Gifty - who was eliminated the next week - laughed off the incident and tweeted: "I didn't even notice I did it 😂😂😂😂😂😂😂😂😂😂😂😂"
Following an investigation, Ofcom declared the matter "resolved" today.
Ofcom said that despite the show "clearly breaching" rules on offensive language, they "took into consideration the live and emotionally-charged nature of the programme, and that ITV had compliance procedures in place to minimise the risk of offensive language being broadcast.
"Ofcom also noted the prompt action taken by ITV following the incident to mitigate any offence caused and reduce the likelihood of a recurrence.
"In light of these factors, Ofcom considered the matter resolved."
