The flag of "England" is the cross of St. George, red "t" on a white background The Union Jack (i.e. the flag of the United Kingdom) includes the crosses of St. George, St. Andrew (Scotland = White "X" on blue background) and St. Patrick (Ireland = Red "X" on white background)
The flag of England represents the patron of England , St. George, which was introduced by Richard I in 1194 A.D. The king's soldiers also wore the flag on their tunics during the war so they didn't kill or be killed by their own men.

Geographically, the British Isles include the islands of Britain and Ireland and all of their off-shore islands. Politically, this means the United Kingdom and the Republic of Ireland, therefore there are six flags, not four. These are; St. George's Cross = England, St Andrew's Cross = Scotland, flag of St David = Wales, St Patrick's Cross = Northern Ireland and the Irish Tricolour = Republic of Ireland. On public buildings within the UK, you are most likely to see the Union Flag, which is an amalgam of the flags of England, Scotland and Northern Ireland.
England is part of the United Kingdom. In the same way, the English flag (a red cross on awhite ground) is part of the Union flag. When the UK (United Kingdom of Great Britain and Northern Ireland) is being represented the Union flag is displayed (not the Union Jack which is only flown on ships). When England is being represented at say a sporting event separate from the rest of the UK then the St. George's flag is used.
