The artist has handed over the complete sum of his £25k award winnings to the trust for venues, which operates to save the United Kingdom's grassroots live music spots.
He was presented with the cheque on 16 October as his third album People Watching was chosen as the top album of the past year.
He has decided to give the cash to the trust, in appreciation of the essential function grassroots venues played in his beginning days.
"I personally wouldn't be doing my current career if it wasn't for all the gigs I did around the area, and beyond, when I was beginning," said Sam Fender. "These spaces are legendary, but they are in difficulty."
Since the start of 2023, at least 150 of these locations have ceased operations – approximately 16% of the whole industry in the UK.
Over the past year, well-known musicians including Pulp, Coldplay, Katy Perry and Ed Sheeran have all backed the trust in its initiatives to keep the scene afloat, by adding a minor surcharge to their admission fees, which benefits independent venues.
Sam Fender also took part, collecting over £100k on his 2024 arena tour to help numerous small stages across Britain.
The money assisted venues that were facing imminent closure due to challenges arising from water damage, blazes and bereavements, as well as licensing issues, court cases and sound issues.
Some locations obtained financial assistance in upgrading facilities and gear that helped musicians and fans.
"The notion that money from shows in big venues helps the independent spots, where it all starts for performers like me, is just logical," the star has said.

"Additionally, I gave a thousand pounds to Highgate Newtown, to their classes, because I trained in gymnastics when I was younger and they needed updated gear," she explained to the media.
In recent years, they contributed their prize money to the youth organization that developed their band, in addition to other independent music bodies.
Additionally winners that year the group gave their prize to a charity for MS after a acquaintance was found to have the condition.
"The victory was quite enough," said artist Heather Small. "The prize was the extra but we didn't require the bonus, because we had the main prize. So our winning touched another person's life."
In the past week, the Music Venues Trust announced it had saved a couple of local spots in that region, by bringing them into community ownership.
One venue in Southampton and the second in Bristol were bought under the Own Our Venues scheme, which is funded by the arts council and supporters who purchase "shares" in the properties.
