The star has donated the complete sum of his £25,000 Mercury Prize cash to the Music Venues Trust, which works to preserve the Britain's independent concert spaces.
Fender was presented with the award on 16 October as his new release his work was chosen as the best record of the last 12 months.
The musician has chosen to give the cash to the trust, in recognition of the vital role grassroots venues had in his initial steps.
"I would not have achieved this success if it hadn't been for all the gigs I did around the area, and beyond, when I was just getting going," stated the artist. "These locations are iconic, but they are in difficulty."
Since the start of 2023, over 150 of these locations have ceased operations – about one-sixth of the total UK scene.
Recently, top acts like the band Pulp, Coldplay, Katy Perry and Sheeran have all supported the MVT in its attempts to support the industry, by applying a modest fee to their ticket costs, which benefits local stages.
Sam Fender also participated, raising over £100k on his 2024 arena tour to help numerous local spots across Britain.
The money supported spaces that were dealing with possible closure due to challenges caused by flooding, fire incidents and family tragedies, as well as licensing issues, conflicts and neighbor objections.
Other venues obtained financial assistance in modernizing amenities and sound and lighting systems that helped performers and concertgoers.
"The concept that revenue from performances in large arenas helps the independent spots, where it kicks off for performers like me, is just logical," the star has said.
Fender is not the first artist to contribute his award funds to good deeds.
Back when Pulp earned the award in 1996 for their album Different Class, vocalist the singer stated that the band would donate their winnings to the organization War Child.
During 2002, artist she divided her award across several organizations, like the children's charity and a Sickle Cell organization.
"And I donated a £1,000 to my local community centre, to their classes, because I trained in gymnastics when I was a child and they lacked updated gear," she told a publication.
In recent years, Ezra Collective donated their funds to the local youth club that nurtured their group, in addition to other independent music bodies.
And winners that year they gave their prize to a MS organization after a close contact was identified with the disease.
"Receiving the award was ample," said vocalist Heather Small. "The money was the bonus but we didn't require the extra, because we had the cake. So our victory affected somebody else's life."
Last week, the Music Venues Trust revealed it had saved a couple of local spots in the South East, by bringing them into local control.
The Joiners in Southampton and the other in Bristol were bought under the Own Our Venues program, which is backed by Arts Council England and music fans who purchase "stakes" in the properties.
