The long-running soap was named best serial drama and Alan Halsall, who played Tarmey's on-screen foster son Tyrone Dobbs, won the award for serial drama performance.
Accepting his award, Halsall paid tribute to Tarmey, who died last year after playing Jack Duckworth in the soap for decades, saying: "I love you pal." Speaking backstage, he said the actor would be looking down on him.
He said: "I'm sure he is. He'll be having a pint of Guinness for me. His wife asked me to wear his watch tonight so I've got it on. This is for him, he guided me from the start of my career, he was such a huge, huge influence on my life, like a second dad on screen."
