The star has handed over the entirety of his £25,000 Mercury Prize prize money to the trust for venues, which functions to preserve the Britain's small live music spots.
He was presented with the cheque on 16 October as his latest record his work was declared the best record of the previous year.
Fender has decided to give the cash to the Music Venues Trust, in acknowledgment of the essential function small stages fulfilled in his beginning days.
"I personally would not have achieved my current career if it wasn't for all the shows I performed around the region, and further afield, when I was just getting going," said Sam Fender. "These venues are legendary, but they are facing challenges."
From early 2023 onward, over 150 of these venues have permanently closed – roughly one-sixth of the entire UK sector.
In the last year, well-known musicians such as Pulp, the group Coldplay, the singer Katy Perry and Sheeran have all backed the trust in its attempts to help venues survive, by adding a small levy to their ticket costs, which benefits local stages.
Fender also joined in, raising more than £100,000 on his live tour to help 38 grassroots venues across the UK.
These funds assisted spaces that were dealing with imminent closure due to issues stemming from floods, fires and bereavements, as well as licensing issues, conflicts and neighbor objections.
Other venues were granted funding support in upgrading infrastructure and sound and lighting systems that helped performers and concertgoers.
"The idea that funds from shows in major spaces supports the smaller venues, where it kicks off for artists like me, is just sensible," the star has commented.
Fender is not the first artist to donate his honor funds to worthy causes.
When the band earned the prize in the mid-90s for their record Different Class, lead singer Jarvis Cocker stated that the act would contribute their cash to the non-profit War Child.
That year, musician she shared her bounty between a few good causes, such as the NSPCC and a Sickle Cell organization.
"I also contributed a thousand pounds to the center, to their classes, because I practiced gymnastics when I was younger and they needed updated gear," the artist explained to the media.
Two years ago, Ezra Collective donated their funds to the community center that supported their band, alongside other independent music bodies.
And winners that year they donated their award to a charity for MS after a friend was diagnosed the condition.
"Winning was quite enough," remarked singer Heather Small. "The cash was the bonus but we didn't require the bonus, because we had the main prize. So our winning impacted another person's life."
Last week, the trust announced it had saved two local spots in south-east England, by transferring them to community ownership.
The Joiners in Southampton and the other in the city were acquired under the community ownership scheme, which is supported by a national body and enthusiasts who buy "shares" in the buildings.
