Re: You tweak and tune your smartmeter, that means you save money
If you don't pay by direct Debit then they usually add a premium to cover their payment handling costs.
E.on electricity allow me to modify my DD in my online account. I can raise it to quite high levels - although I have never tested for any actual limit. However - it only allows a decrease up to 10% - no matter how much excess credit is building up.
British Gas is similar - except you can't decrease it in the online account details - you have to get through to a person to negotiate a reduction.
There is some UK regulation in the offing to restrict suppliers from holding onto customers' large credit balances.
