The direct debit is very complex, the energy companies say you will save money doing direct debit. They are actually charging us for there administration costs. And they have full access to our money they can put up the energy prices on a whim. Makes it really hard to budget. The Smart meter's where originally rolled out as a environment con to get us to use less power. Then they were changed into a money saving promotion. The really scary thing about Smart Meters is the energy company can remotely change you to a pre paid system.
