Emergency credit is a pre-set reserve that can be selected by pressing the RED “Emergency
Credit” button when the pre-paid credit has fallen below a given level. The display will change
to £XXX.XX Emer to indicate the amount of emergency credit left to the consumer. The debt is
to be repaid before the meter is back into prepaid credit. (Emer Credit Left £XXX.XX) may be
viewed by pressing the display button.
3.6.2 Reduction
The amount of emergency credit remaining (Displayed as £XXX.XX Emer) will be reduced as
electricity is consumed and any Standing Charge collected. The Debt will also be increased by
the same amount. (Emer Credit Left £XXX.XX) and (Current Debt £XXX.XX) may be viewed by
pressing the display button.
3.6.3 Expiry
When the emergency credit has fallen to zero the supply will be disconnected and the display

pressing the display button.
