The 36-year-old guitarist and his band mates - Tom Meighan, Chris Edwards and Ian Matthews - will be headlining the festival at Richmond Park on August 25.
Speaking on Absolute Radio, he said: ''We went to Reading as kids, that yellow poster I got and framed it because it meant so much. It's a big old gig and we attacked it and it was amazing, weren't it? It was one of the best days ever.''
The 'Shoot The Runner' hitmakers also have new album 'For Crying Out Loud' dropping on April 28.
Serge recently said it is inspired by the head of Motown Records, Berry Gordy, and his idea of catching the ear of listeners within the first eight bars of a song.
He recently said: ''On a grand scale we went to save guitar music from hell and be the saviours of rock and roll.
''In reality, I wanted to try and make an album full of really good, well-crafted songs.
''I was thinking about the 70s, when guitar music was hitting that beautiful point, with strong melodies and great riffs. And I was thinking about Motown and how Berry Gordy had this philosophy of, 'Get 'em within the first eight bars.''
