The company has confirmed that to date it has had 428 standards complaints since the BBUK finale aired last Friday on August 15.
While a breakdown of what the complaints are about is not available, no doubt most of them relate to Helen Wood's controversial win over Ashleigh Coyle.
The numbers make the episode the most complained about of the series, with more than 300 being received about Helen Wood's behaviour earlier on in the latest run.
In all, Helen's actions on the show have totaled some 1,500 complaints over the past three months.
With regards to the final, many have claimed that they were unable to vote for Ashleigh in the last few minutes of the votes with some saying that her voting line closed 5 minutes before was announced on TV.
However it does appear that at least some of these complaints stem from confusion: The mobile voting's app purchase system has always closed 5 minutes before the lines did, as stated in the Terms and Conditions.
The online petition calls for an investigation into the final result, including the claims that some viewers could not vote for certain housemates.
Ofcom will assess the complaints and decide whether or not they warrant an investigation.
