The band, who unveiled a new lineup earlier this year, will top the bill at Clapham Common on June 12, NME reports.
Borrell recently confirmed that the band would be playing new material at the outdoor show.
"The rumours are true, we're playing a headline show in London this summer," he said in an official video at the time. "London gigs have become sort of homecoming gigs for the band, and that's probably one of the best things I've ever experienced."
Previous headliners at Get Loaded have included Orbital and Iggy & The Stooges.
In 2009, Borrell suggested that Razorlight would like to work with Noel Gallagher on their fourth studio album.
