Newly elected Labour MP for Barnsley South, Stephanie Peacock, says the victory is a "very clear message of confidence" from voters.
Speaking after the announcement, she said: "They have chosen hope over division, they have chosen a changed Labour party, back in the service of working people.
"A Labour government that has pledged to deliver economic stability, a government for those who haven't been able to access the treatment they need, for those who have lost faith in our justice system, rest assured, we will rebuild our public services.
"And for the thousands of miners, who powered our country, we will finally deliver justice for the mineworkers pension scheme."
Labour's Dan Jarvis, the former Mayor of South Yorkshire, is celebrating his victory in Barnsley North after suggestions the seat would be won by Reform UK.
In a post on X, external, Mr Jarvis says 'reports of my demise had been greatly exaggerated'.
In an interview with BBC Radio Sheffield, he added: "I think some people had already written my political obituary but I'm delighted that we've secured a good, big win.
"I've doubled my majority and I'm immensely proud to be elected to represent the people of Barnsley North."

"If these polls are right, we've got five years of decline and hopefully people will see that and then we can have a strong Conservative government and rectify their errors," he said.
"If we can come back then, then hopefully we can set the country back to where it needs to be."

South Yorkshire was full of surprises in 2019, but where will the interest be this year?
I'm tipping these three seats as ones to watch.
Sheffield Hallam – the smallest majority in South Yorkshire and one of the few constituencies nationwide which is head-to-head between Labour and the Lib Dems. Labour won it in 2019 with a slim majority of 712 and it’s number three on the Lib Dems’ target list.
Rother Valley – the constituency was Labour for over 100 years before turning blue in 2019. It’s the epitome of a red wall seat, where mining communities voted Conservative for the first time in generations.
Barnsley South – This was one of the first places Nigel Farage visited after announcing his return as Reform UK leader. He said he doesn’t expect to win but wants to come a strong second to build the groundwork for the next general election.

In Rotherham, there are three seats up for grabs for Rother Valley, Rotherham Central and Rawmarsh and Conisbrough.
The counting hall is hot - packed with volunteers furiously flicking through papers.
Image source, Oli Constable/BBCWe've just caught up with Reform UK candidate Tony Harrison, who's standing in the Rother Valley seat. He's seen the exit poll for Barnsley North and South which suggest a Reform UK win.
"It's looking quite positive," he says.
When asked why he thinks that is, he adds: "Quite strange times, I think it all stems from Brexit. There was a high Brexit vote in Barnsley."
Image source, Oli Constable/BBCDoes he think he could win his seat from the Conservatives in Rother Valley?
"Yeah, never say never. Think it'll be a tight-run thing. The Conservative candidate seems to be doing better than expected, certainly not an easy night for Labour. I might come a close second maybe, or even maybe even take the seat. More likely to be a close second."
Labour councillor Chris Read, leader of Rotherham Council, has said not to judge the exit polls "too soon", and wants to wait for "the real votes" to be counted.
Image source, Oli Constable/BBC"We did of course have a big Leave vote [in Rotherham], we had a big Ukip group on the council before, so in some ways perhaps not too much of a surprise Reform are doing well. I don't think they're doing well enough to challenge the two big parties for seats here in Rotherham," he adds.

Instead of visiting the so-called "red wall" seats which made the headlines in 2019, both party leaders have instead concentrated on safe Conservative seats in other parts of the country.
Liberal Democrat Leader Ed Davey bounced through SheffieldHallam, where the party is going head-to-head with Labour.
But even that visit – spent making insect houses – seemed subdued for Mr Davey, who has spent his campaign bungee jumping, riding fairground rides and performing water stunts.
Reform UK leader Nigel Farage had the most high profile visit, riding through Barnsley on an open top bus, glad-handing shoppers and addressing crowds with a microphone, though his foray was marred when a member of the public hurled a number of items towards him.
Our reporter at the Barnsley North count says a declaration is expected within the next 10 minutes.
