You say it may only be pennies but they all add up.

Just think if eon "mistakenly" took an extra penny from every customer in every direct debit...that's a lot of free money at the end of the year.

And how many people would complain about a few pence, let alone even notice it?

Insignificant and pointless I would have thought, especially when they just add a tenth or two of a penny to the cost of 1 kWh and they'll be reaping it in every hour of the day and night.
