A Gold Coast insulation company has been fined $100,000 over the death of an installer, but no conviction has been recorded.

Mitchell Sweeney, 22, was electrocuted while installing insulation at Millaa Millaa in far north Queensland last year.

His Gold Coast employer, Titan Insulations, this afternoon pleaded guilty to failing conduct its business in a way that was electrically safe.

Magistrate Paul Cluck ordered the company to pay a $100,000 fine within two years and have no conviction recorded.

He said while the company took steps to train its staff, there was a failure to ensure metal staples were not used.

Company directors Nicholas William Lindsay and Frederick Ramon Palomar had also been charged with failing to ensure the company complied with the Electrical Safety Act.

The parties agreed the complaint against the two directors should be dismissed.

Speaking outside the court, Mitchell Sweeney's family said they were satisfied with the ruling.

Mr Sweeney's brother, Justin Sweeney, says it's been a difficult time.

"It hasn't quite sunk in yet, but initially we're happy with the verdict," he said.

"It's a big step moving forward to gaining some closure for our family.

"We want to thank everyone at Queensland Workplace Health and Safety for their tremendous job."
