How do I read my prepayment meter?

From time to time, we may need you to read your meter. If we do, this helpful guide will tell you how to do exactly that.

A couple of noteworthy points:

  • We don't need any numbers in red or after a decimal place
  • Debt on a prepay meter may be spread across multiple screens, so it’s worth checking them all if necessary
  • Gas debt = debt built up from gas use
  • 'Owed' debt = debt built up from the meter's daily standing charge


Electricity (Blue Button Meter)


Press the blue button to switch through the different screens. There are several screens to get through, each with a letter on the left-hand side.

A - The current credit amount on your electricity meter

B - Test screen

C - Time and rate in use

D - Date and rate in use

E - Total credit 

F - Standing charge and debt collection amount

G - Total units used (ever)

H - The current meter reading

I - Price per unit

J - If you have a two-rate meter, this is your rate 2 reading

K - Price per unit rate 2 (if you have a two-rate meter)

The following will require the key or card to be in the meter:

R - Emergency credit available

S - Total debt amount on the meter

T - Dect recovery rate (how much you're paying back a week)



Gas (A and B button Meter)


The screen displaying 'Meter Index' shows your current meter reading. This can be accessed by pressing the red A button to cycle through the screens.

To check the amount of debt, press the red button until you see ‘Prepay ON' and the meter beeps. Insert your key or card, you cycle through the screens listed below by pressing the red A button.

Gas debt is on screen 27, built up standing charge debt next to 'Owed' on the default meter screen:
