Worst case scenario is a hot day and you could need up to 12 litres of drinks, so that's what your plan should include.
Unlikely I would drink anywhere near that. There's no such thing as a 'hot' day in England ;)
I did the 100 with ~2.2L and I've never consumed near 12L during a sportive or other long ride.
