Scottish Power billing

I had a YW statement last week that showed me £75 in credit over the year

That's not bad at all, they are supposed to aim to have it balance out winter/summer and I'd wager that's maybe 10% or less out over the year.

When it's £400, that's different! Makes a nice surprise when you find out though

Every supplier will charge extra when payment isnt by DD and some will even give a reduced DF discount when DD isnt used.

Phew, so they are overcharging you less so will build up a smaller credit
