The artist has given the complete sum of his £25,000 award cash to the trust for venues, which works to preserve the UK's grassroots music venues.
The star was given the prize on October 16 as his third album People Watching was named the outstanding release of the last 12 months.
The musician has decided to donate the funds to the trust, in acknowledgment of the essential function small stages had in his early career.
"I would not have achieved what I am doing today if it wasn't for all the shows I performed around the area, and elsewhere, when I was just getting going," remarked the artist. "These spaces are iconic, but they are facing challenges."
Since the start of 2023, over 150 of these locations have permanently closed – about one-sixth of the whole industry in the UK.
Over the past year, top acts like Pulp, Coldplay, Katy Perry and Ed Sheeran have all aided the trust in its attempts to help venues survive, by including a minor surcharge to their ticket costs, which goes to help local stages.
Sam Fender also joined in, collecting over £100k on his recent tour to help 38 local spots across England, Scotland, and Wales.
The donation supported locations that were facing imminent closure due to issues stemming from flooding, fires and bereavements, as well as permit problems, legal disputes and sound issues.
Additional spaces received financial assistance in modernizing facilities and sound and lighting systems that directly benefitted musicians and fans.
"The notion that funds from shows in major spaces helps the smaller venues, where it all starts for performers like me, is just sensible," the star has stated.
The musician is among several artists to contribute his Mercury Prize winnings to good deeds.
When the band earned the trophy in 1996 for their record the album, frontman Cocker stated that the act would donate their cash to the organization the charity.
That year, musician she split her award across several good causes, like the children's charity and a Sickle Cell charity.
"Additionally, I gave a £1,000 to my local community centre, to their classes, because I trained in gymnastics when I was growing up and they required updated gear," Ms Dynamite told a publication.
Previously, Ezra Collective donated their prize money to the local youth club that developed their act, in addition to other independent music bodies.
And 1994 winners they contributed their winnings to a multiple sclerosis charity after a close contact was found to have the condition.
"Receiving the award was sufficient," remarked vocalist the singer. "The money was the cherry on top but we didn't need the extra, because we had the honor. So our winning touched another person's life."
In the past week, the trust shared it had rescued a couple of local spots in south-east England, by placing them under public stewardship.
One venue in that area and the other in that location were purchased under the public acquisition scheme, which is backed by a national body and music fans who acquire "ownership units" in the venues.
