<p>A customer’s direct debit payment arrangement should avoid large credit or debit balance at the end of 12-month period. Energy suppliers are required to ensure a customer’s direct debit payments are set on the best available information. For existing customers, the payment level should be based on energy consumption over the previous year with adjustments for price changes.
