There is an Edward Bonner, 24, living in Portsmouth in 1911.
I haven't seen the original but, using the index, I think he is living with Louisa Bonner, 22; Jessie Bonner, 3; and Lily Bonner, 18m. He was there in 1901 as well, living with his family, where it shows he was born in Scotland (confirmed on the 1911). His parents were Daniel and Jane. Scotlands People have an Edward Bonner born in 1886 and 1887. He doesn't seem likely to be your Edward.
There is another Edward, 20, living in Southampton. He is a little young and I can't establish where he was born.
