The artist has donated the complete sum of his £25,000 award prize money to the trust for venues, which functions to save the Britain's independent concert spaces.
Fender was given the award on mid-October as his new release the album was named the top album of the last 12 months.
The musician has opted to hand the money over to the Music Venues Trust, in recognition of the vital role grassroots venues had in his initial steps.
"As an artist would not have achieved what I am doing today if it hadn't been for all the performances I did around the North East, and beyond, when I was beginning," remarked Fender. "These spaces are iconic, but they are in difficulty."
Beginning in 2023, more than 150 of these spaces have shut down – approximately one-sixth of the entire UK sector.
Over the past year, well-known musicians such as the band Pulp, Coldplay, the singer Katy Perry and Ed Sheeran have all supported the Music Venues Trust in its attempts to keep the scene afloat, by applying a minor surcharge to their admission fees, which supports smaller concert halls.
Fender also joined in, collecting more than £100,000 on his live tour to support thirty-eight local spots across Britain.
The money helped venues that were confronting possible closure due to difficulties caused by water damage, blazes and family tragedies, as well as permit problems, conflicts and sound issues.
Other venues received monetary aid in modernizing amenities and sound and lighting systems that positively impacted performers and audiences.
"The idea that funds from shows in large arenas supports the local stages, where it begins for artists like me, is just logical," Sam Fender has commented.
He is far from the only musician to donate his Mercury Prize funds to good deeds.
When they received the trophy in 1996 for their album the album, lead singer Jarvis Cocker declared that the group would contribute their cash to the non-profit War Child.
That year, musician the artist divided her prize between a few organizations, like the children's charity and a charity for Sickle Cell.
"Additionally, I contributed a £1,000 to my local community centre, to their gymnastics class, because I practiced gymnastics when I was a child and they lacked new equipment," Ms Dynamite told the media.
In recent years, the band contributed their funds to the youth organization that supported their band, alongside other local music groups.
Additionally 1994 winners the group contributed their award to a charity for MS after a close contact was diagnosed the illness.
"Receiving the award was ample," remarked artist the singer. "The cash was the cherry on top but we didn't need the bonus, because we had the honor. So our success affected another person's life."
Last week, the trust shared it had saved two grassroots venues in south-east England, by bringing them into public stewardship.
One venue in the city and the second in Bristol were bought under the Own Our Venues initiative, which is supported by Arts Council England and enthusiasts who buy "ownership units" in the buildings.
