Am I missing something or are EDF double billing electricity and gas units each month.

Example of an EDF electricity and gas bill.
Electricity previous reading 6296.  Electricity latest reading 6546.  Billed for 250 units as would be expected.
The following month's bill reads.
Electricity previous reading 6546.  Electricity latest reading 6596.  Billed for 50 units. The previous month's bill included the cost of unit number 6546 so why the charge for it again.
The same principle is for gas.  Maybe I am missing something and its correct, but does not seem right to me.

What's 1 + 5?
What's 6 + 5?
What's 1 + 10?

It's right. If they included unit 6546 in the second bill you would be charged for 51 units....count it on your fingers if you don't believe me,,,

Thankfully I can do mental addition and subtraction. I can even use a calculator and arrive at the same answer, thankfully.
In the example given unit number 6546 is included in the total units used and charged accordingly.  The following month's bill unit 6546 is included in the total units used again. 
My question is not about adding 5 + 5, it's the method of calculation.

Oops, that's a little embarrassing now I have done as you suggested.  I had 50 in my head from the bill, mentally subtracting and calculator.  Thanks.

Think of it this way. The stop point and the start point for each billing cycle have to be the same: in this case 6546.

Actually this is not really a stupid question - the standing charge works like the OP thought.

Energy does not come in discrete units so the stop and start points are the same between bills. However days are discrete units, so the start date on one bill needs to be one day later than the stop date of the previous bill, otherwise you would be double billed for one day.

This is very basic maths so one hopes that every supplier would at least get this right...
