From the cap badge shown, we know Fred is in either the Royal Field or Royal Garrison Artillery. There is no way of distinguishing between the two from the picture.
His uniform is of the type that was not issued until late 1914, when the demand for uniforms meant that they needed to be produced cheaply and quickly.
Unfortunately, there is no other military information relating to Fred – no service record or medal roll card can be identified. He survived the war, as he appears in a picture of a football team.
