The artist has donated the full amount of his £25k honor prize money to the Music Venues Trust, which works to preserve the Britain's small music venues.
He was presented with the prize on October 16 as his latest record the album was chosen as the outstanding release of the past year.
He has chosen to give the cash to the trust, in recognition of the crucial part small stages played in his beginning days.
"I wouldn't be doing this success if it hadn't been for all the performances I performed around the area, and further afield, when I was starting out," remarked Sam Fender. "These spaces are legendary, but they are facing challenges."
From early 2023 onward, over 150 of these spaces have shut down – roughly 16% of the entire UK sector.
Recently, top acts including the band Pulp, Coldplay, Katy Perry and Sheeran have all aided the Music Venues Trust in its initiatives to help venues survive, by including a small levy to their ticket costs, which benefits local stages.
He also joined in, collecting over £100k on his 2024 arena tour to help numerous grassroots venues across England, Scotland, and Wales.
The money assisted venues that were facing imminent closure due to issues stemming from floods, fires and bereavements, as well as permit problems, legal disputes and noise complaints.
Additional spaces were granted monetary aid in modernizing amenities and technical equipment that directly benefitted musicians and concertgoers.
"The idea that funds from concerts in large arenas backs the independent spots, where it all starts for musicians like me, is just sensible," the star has said.
Fender is not the first artist to donate his Mercury Prize winnings to good deeds.
Back when they earned the prize in the mid-90s for their album their work, frontman Jarvis Cocker announced that the group would give their cash to the charity the charity.
During 2002, rapper and singer Ms Dynamite split her prize among several charities, such as the NSPCC and a Sickle Cell charity.
"I also donated a grand to my local community centre, to their gymnastics class, because I practiced gymnastics when I was growing up and they needed better apparatus," Ms Dynamite shared with a publication.
Two years ago, Ezra Collective donated their winnings to the youth organization that developed their group, in addition to other grassroots music organisations.
Additionally the 1994 recipients M People donated their prize to a charity for MS after a acquaintance was diagnosed the illness.
"Receiving the award was sufficient," stated artist Heather Small. "The money was the bonus but we didn't need the extra, because we had the main prize. So our success touched another person's life."
Recently, the Music Venues Trust announced it had saved several small stages in the South East, by placing them under local control.
The Joiners in the city and the other in that location were purchased under the Own Our Venues program, which is funded by the arts council and enthusiasts who acquire "stakes" in the properties.
