Krept told Newsbeat: "Being nominated for four awards, when we work so hard in the studio, we don't know if you are going to win one award or not.
"We are working hard and were not thinking about awards. We are just thinking about making the best project and doing the best we can."
Lianne La Havas, Skepta and Stormzy each have three nominations, while FKA twigs, Little Simz, Bugzy Malone, Lethal Bizzle and Mark Ronson have two.
