His track "Man" also won Best Contemporary Song.
The award ceremony is one of the most prestigious in UK music, recognizing excellence in songwriting across genres. Previous winners include Adele, Amy Winehouse, Calvin Harris and Lily Allen. Skepta's win, as reported by The Guardian, signals grime's increasing prominence in the UK, and it also marks a rare win for a black artist in the Songwriter Of The Year Category.
The grime MC, whose award was presented by his sister (and Beats 1 Radio host) Julie Adenuga, also won Best Contemporary Song for "Man," from his 2016 album Konnichiwa.
