You can choose whether you want to pay monthly or quarterly. If you decide to pay by direct debit your supplier will estimate how much energy you'll use over the year and divide this into 12 equal monthly instalments. This is the most popular way to pay, and you’ll usually get a better price using this method.
If you’d rather pay by quarterly variable direct debit you can but this may make budgeting harder, which is something to bear in mind. Most people find a smaller, regular monthly payment easier to manage.
Alternatively, you can select to pay in receipt of a bill which means that you typically have 14 days to pay by cash, card or cheque once you receive your quarterly bill. The amount you pay depends on how much you’ve used over the previous three months.
