The rocker was chosen as the recipient of the top music industry honour for his contribution to the music and entertainment industry and his longtime work with charity Teenage Cancer Trust.
He was presented with the prize by former Top Gear host Jeremy Clarkson at a ceremony held in aid of music therapy charity Nordoff Robbins and the Brit Trust.
On accepting his award, Daltrey paid tribute to his bandmates and praised the charities, saying, "I got lucky. I found John Entwistle. I found Pete Townsend. I don’t know if it was lucky but I found Keith Moon!
"The Teenage Cancer Trust not only helps teenagers; it also helps parents. And it takes so much work to maintain where we are with Nordoff Robbins."
Following the show, he told Musicweek.com it felt like a "big honour" and he was glad to receive it at an event that was so important in raising awareness for the charities.
"We were one of the founders of Nordoff Robbins in the early ‘70s when a lady wrote to us and said, 'I’m going to do this charity to teach autistic children through music, will you support it?' And we did, so I’m very happy to see it still here but equally I’m aware that they need events like this to make the public realise they are there. Otherwise people are left stranded," he shared.
The ceremony was presented by radio DJ Jo Whiley and featured live performances from former Keane frontman Tom Chaplin, country duo The Shires and rocker Wilko Johnson.
Previous recipients of the award include Simon Cowell, Elton John, Gary Barlow and Annie Lennox.
