BBC Watchdog presenter Dan Penteado has admitted £24,000 benefits fraud.
Kerry O'Neill, prosecuting, said the offences went back to 2007 when Penteado filled out his first claim form and failed to declare he had another bank account.
The court heard that Penteado repeated the fraud up to 2011.
In that time he failed to tell Bournemouth Borough Council he had been paid more than £56,000 for his work on Rogue Traders from 2008 to 2011.
Miss O'Neill said. "He failed to notify the borough council of the money coming in."
No mitigation was put put forward by his solicitor, Terrence Scanlan, at the hearing.
The Portuguese-born presenter, who was wearing a white shirt, black tie, black trousers and a black jumper and carrying a black biker jacket, left court without comment.
He started working with Mr Allwright in 2001.
