The star has handed over the complete sum of his £25k award winnings to the trust for venues, which works to protect the UK's small live music spots.
Fender was presented with the cheque on October 16 as his latest record his work was chosen as the best record of the previous year.
The musician has opted to donate the funds to the trust, in acknowledgment of the vital role grassroots venues fulfilled in his early career.
"I personally wouldn't be doing what I am doing today if it weren't for all the shows I played around the area, and beyond, when I was just getting going," remarked Sam Fender. "These venues are legendary, but they are facing challenges."
From early 2023 onward, over 150 of these spaces have ceased operations – roughly 16% of the entire UK sector.
Recently, top acts including Pulp, Coldplay, the singer Katy Perry and Sheeran have all backed the trust in its attempts to help venues survive, by including a minor surcharge to their admission fees, which goes to help local stages.
Fender also joined in, raising over £100k on his live tour to help numerous local spots across Britain.
The donation assisted venues that were confronting possible closure due to issues arising from flooding, fire incidents and bereavements, as well as licensing issues, conflicts and neighbor objections.
Some locations were granted financial assistance in upgrading amenities and gear that directly benefitted musicians and concertgoers.
"The notion that revenue from concerts in large arenas supports the independent spots, where it kicks off for performers like me, is just sensible," the star has stated.
He is not the first artist to donate his Mercury Prize funds to charitable organizations.
When Pulp earned the award in the year 1996 for their album the album, vocalist Jarvis Cocker declared that the band would contribute their cash to the organization War Child.
During 2002, rapper and singer she divided her bounty between several charities, including the NSPCC and a Sickle Cell charity.
"I also gave a £1,000 to my local community centre, to their gymnastics class, because I did gymnastics when I was a child and they required better apparatus," the artist told the media.
In recent years, they contributed their prize money to the local youth club that developed their group, alongside other local music groups.
Also the 1994 recipients M People donated their winnings to a charity for MS after a friend was found to have the illness.
"Receiving the award was quite enough," stated artist the singer. "The cash was the cherry on top but we didn't need the cherry, because we had the honor. So our winning affected the lives of others."
Last week, the trust announced it had protected two grassroots venues in south-east England, by placing them under community ownership.
The first in Southampton and The Croft in the city were acquired under the Own Our Venues initiative, which is supported by the arts council and enthusiasts who purchase "stakes" in the buildings.
