A goalless draw with Charlton was enough to secure promotion to the Premier League - and a £100m bonanza - after three successive seasons of play-off heartache.
And defender Mark Hudson said: "We thoroughly deserve this with the consistency we've had this year.
"We've been top since November and now we're promoted. We'll celebrate now then go for that title.
"It's a great achievement. The manager Malky Mackay has been fantastic in the two years he has been here. I'm thankful to Dave Jones as he brought me here. But Malky really goes into the fine details.
"He is the ultimate professional - that's what we try to give back."
