Britain reached total war in the Seven Years' War

When did England or Britain first fight what could be called a total war?

Some Dutch wars came close, but Britain was effectively fighting a period-specific total war by the second year of the Seven Years' War.

Some Anglo-Dutch wars came close, but the discussion places Britain's first clear period of total war by about the second year of the Seven Years' War. Total mobilization did not mean drafting the same share of people as an industrial state, because agriculture still required much more labor. Britain instead made war the primary function of government and used commercial activity, taxation, debt, and trade income to finance its own forces and keep German allies fighting. That economic method was part of mobilization rather than evidence that civilian commerce remained outside the conflict. The example supports a period-specific definition of total war based on the maximum sustainable commitment of the society that actually existed.
