The artist has given the entirety of his £25,000 honor winnings to the Music Venues Trust, which functions to protect the UK's independent concert spaces.
Fender was presented with the prize on mid-October as his third album his work was chosen as the top album of the past year.
Fender has chosen to donate the funds to the Music Venues Trust, in recognition of the crucial part small stages had in his initial steps.
"As an artist would not have achieved this success if it wasn't for all the performances I played around the region, and elsewhere, when I was beginning," remarked the artist. "These locations are legendary, but they are facing challenges."
Beginning in 2023, over 150 of these spaces have shut down – roughly 16 percent of the entire UK sector.
In the last year, well-known musicians like the band Pulp, Coldplay, Katy Perry and Sheeran have all aided the MVT in its efforts to keep the scene afloat, by including a modest fee to their ticket prices, which goes to help smaller concert halls.
Fender also joined in, raising more than £100,000 on his live tour to support 38 small stages across the UK.
The money assisted spaces that were confronting potential shutdown due to difficulties stemming from water damage, blazes and family tragedies, as well as regulatory hurdles, conflicts and sound issues.
Some locations obtained funding support in modernizing infrastructure and gear that helped artists and fans.
"The idea that funds from shows in large arenas helps the smaller venues, where it all starts for artists like me, is just logical," Sam Fender has said.
He is far from the only musician to give his Mercury Prize winnings to good deeds.
In they won the prize in 1996 for their record the album, lead singer Jarvis Cocker stated that the act would contribute their cash to the organization the charity.
In 2002, rapper and singer the artist split her bounty between several charities, such as the NSPCC and a Sickle Cell charity.
"I also contributed a grand to the center, to their gymnastics program, because I did gymnastics when I was a child and they needed new equipment," the artist told a publication.
Two years ago, the band donated their funds to the local youth club that developed their group, as well as other independent music bodies.
And the 1994 recipients the group contributed their award to a MS organization after a friend was diagnosed the illness.
"Receiving the award was quite enough," said vocalist Heather Small. "The money was the cherry on top but we didn't need the cherry, because we had the honor. So our success touched somebody else's life."
In the past week, the trust shared it had saved a couple of local spots in south-east England, by bringing them into local control.
One venue in that area and The Croft in Bristol were acquired under the public acquisition scheme, which is funded by the arts council and music fans who purchase "ownership units" in the properties.
