The artist has handed over the complete sum of his £25k Mercury Prize winnings to the trust for venues, which works to preserve the UK's small concert spaces.
The star was presented with the cheque on 16 October as his new release his work was chosen as the outstanding release of the past year.
He has opted to give the cash to the trust, in recognition of the vital role grassroots venues had in his beginning days.
"I wouldn't be doing my current career if it wasn't for all the performances I performed around the region, and elsewhere, when I was just getting going," stated Sam Fender. "These locations are legendary, but they are struggling."
Beginning in 2023, more than 150 of these spaces have permanently closed – approximately 16% of the total UK scene.
In the last year, well-known musicians such as the band Pulp, Coldplay, Katy Perry and Sheeran have all aided the trust in its initiatives to help venues survive, by including a small levy to their ticket costs, which goes to help smaller concert halls.
Sam Fender also took part, generating over £100k on his live tour to support 38 small stages across Britain.
These funds assisted venues that were confronting possible closure due to issues stemming from water damage, fires and family tragedies, as well as regulatory hurdles, court cases and noise complaints.
Some locations were granted financial assistance in modernizing amenities and technical equipment that helped performers and concertgoers.
"The idea that money from shows in large arenas backs the smaller venues, where it begins for artists like me, is just common sense," the star has commented.
Fender is far from the only musician to give his award prize money to good deeds.
In the band received the trophy in 1996 for their release Different Class, frontman the singer declared that the act would donate their cash to the organization War Child.
That year, artist Ms Dynamite shared her award among multiple good causes, such as the NSPCC and a Sickle Cell charity.
"I also contributed a grand to Highgate Newtown, to their gymnastics class, because I trained in gymnastics when I was younger and they needed updated gear," she shared with a publication.
In recent years, Ezra Collective contributed their winnings to the local youth club that supported their act, alongside other independent music bodies.
And the 1994 recipients M People donated their winnings to a multiple sclerosis charity after a close contact was identified with the illness.
"Winning was ample," stated singer Heather Small. "The prize was the extra but we could do without the bonus, because we had the main prize. So our victory touched another person's life."
Last week, the trust revealed it had protected a couple of grassroots venues in that region, by transferring them to public stewardship.
The first in Southampton and the second in Bristol were purchased under the public acquisition program, which is backed by the arts council and enthusiasts who purchase "ownership units" in the buildings.
