A pre-payment meter is a metering device which enables you to pay for your electricity as you go. A pre-payment key can be topped up at various outlets around the Island. Once the key is inserted into the meter the credit you have purchased will be available for use.

No, not all customer meter positions are suitable for the installation of a pre-payment meter. Please contact our Customer Services Team (01624) 687675 for further information.

There are many pre-payment meter outlets on the Isle of Man which have convenient opening hours.

You will need to invoke your emergency credit by inserting the key into your meter. Only use this facility when your credit is below £1. The emergency credit facility allows you to borrow £30 extra credit until you can charge your key again.

Once you have used all your emergency credit your supply will disconnect until you pay back the emergency credit. You must purchase additional credit as soon as possible to prevent this from happening.

Please remember when you next charge your key you will have to pay back the emergency credit that you have used, up to a maximum of £30.

We won't cut your electricity off at night... even if you run out of emergency credit.  

This non disconnection feature is only functional to the meter shown.

The meter will collect the value of electricity used and will deduct the full amount when you next top up.

To verify what amount you will be required to pay, press the blue button on the meter until the letter “B” appears on the left of the display, the amount shown is what is required.

Non disconnect meter type is a KBD or KBC meter,  which is detailed on the front of the meter.

The friendly meter times are 8:00am to 8:00pm Monday to Friday and all day on Sundays and the following bank holidays; Christmas Day and Boxing Day, New Years Day, May Bank Holidays and August Bank Holidays.
