The star has given the entirety of his £25,000 Mercury Prize cash to the trust for venues, which functions to preserve the Britain's independent concert spaces.
He was given the cheque on October 16 as his new release People Watching was named the top album of the past year.
Fender has opted to give the cash to the trust, in acknowledgment of the vital role local spots fulfilled in his initial steps.
"I would not have achieved this success if it wasn't for all the shows I did around the area, and beyond, when I was starting out," stated the artist. "These venues are legendary, but they are facing challenges."
From early 2023 onward, more than 150 of these locations have ceased operations – about 16 percent of the total UK scene.
Recently, major artists including Pulp, Coldplay, Katy Perry and Ed Sheeran have all supported the trust in its efforts to help venues survive, by including a minor surcharge to their ticket costs, which supports independent venues.
Sam Fender also joined in, generating over £100k on his live tour to support numerous grassroots venues across Britain.
The money supported spaces that were dealing with imminent closure due to issues stemming from water damage, blazes and personal losses, as well as licensing issues, legal disputes and sound issues.
Additional spaces were granted financial assistance in improving amenities and gear that helped performers and audiences.
"The concept that money from shows in major spaces supports the smaller venues, where it all starts for performers like me, is just logical," Fender has commented.
The musician is not the first artist to give his award funds to good deeds.
Back when Pulp earned the award in the year 1996 for their album Different Class, vocalist Jarvis Cocker announced that the band would donate their winnings to the organization War Child.
In 2002, artist she shared her award across multiple charities, like the NSPCC and a Sickle Cell charity.
"I also donated a grand to Highgate Newtown, to their gymnastics program, because I trained in gymnastics when I was younger and they lacked better apparatus," she told the media.
In recent years, the band contributed their winnings to the community center that supported their act, as well as other local music groups.
And the 1994 recipients they contributed their prize to a multiple sclerosis charity after a friend was diagnosed the condition.
"Receiving the award was ample," said vocalist the singer. "The cash was the extra but we didn't need the extra, because we had the main prize. So our success impacted somebody else's life."
In the past week, the Music Venues Trust announced it had saved two grassroots venues in that region, by transferring them to community ownership.
The Joiners in Southampton and The Croft in the city were acquired under the public acquisition program, which is backed by Arts Council England and music fans who purchase "stakes" in the buildings.
