£12 Government rebate for electricity users
npower says: "We're doing this as part of a project from the government. It means we can provide every one of our electricity customers with the same £12 amount. All the other energy suppliers are doing this too."
"If you pay your electricity bill by direct debit or when we send you a bill, then you'll see a line on your bill with a £12 credit. You don't have to do anything."
"If you're one of our prepayment customers the process is a little different."
"Because we can't yet add the £12 to your prepayment meter automatically we’re sending you a letter to use at your nearest Post Office. You need to take the letter and your prepayment card/key to the Post Office with your identification (listed on the letter), and the staff will top it up for you."
The Government themselves have prattled on about it and why it is happening and all that. If you're interested in the ins-and-outs of it all, then click here.
The short version of all this, is that the Government have vowed to lower energy bills for everyone and so, everyone gets £12, which means you can go an buy some beer or a CD from Asda or something.
