This includes receiving all communications electronically; pay on time by direct debit and at least the recommended amount (or more) each month; provide meter readings online at least once every 3 months. If you satisfy all of these requirements in a calendar quarter, then we will credit your account with £7.50 per fuel for that quarter as a thank you. However, if you don’t receive the Self Service Reward one quarter, we will still apply the Self Service Reward to your bill the next time you have met the rules in a full calendar quarter.
