The left hand (as we look at it) is the General Service medal ribbon from 1962 to 2007, awarded for service in a number of circumstances depending on the time frame.(Wikipedia will help). The uniform looks the same period. The buttons are the black buttons of rifle regiments, the exact one would also depend on the time frame as regiments changed/were amalgamated but included for example the Royal Green Jackets, Rifle Brigade, present day Rifles etc etc. (Purists please note my caveat about time frame!). The second ribbon - don't know but looks a bit rare so may help to define this all better.
