How to read my bill

How to read your half-hourly bill

1. How do I know if I've got a half-hourly meter?
A half-hourly electricity meter has a profile class of ‘00’ and appears as the first two digits of your unique supply number. Your profile class is based on the amount of energy you use and when you use it.

2. Your unit rate(s)
This is your price for the electricity you use. Depending on the tariff you agree with us, you may have more than one rate, for example, day, night and weekend rates. These rates will be shown separately on your bill along with the times of the day or night that each rate applies.

3. Your energy usage
Your half-hourly meter captures your energy consumption every half an hour and transmits this data automatically to your energy supplier. So you won’t find any meter readings on your bill, but you can view and track your half-hourly energy data through your online account at any time. Log in or register for an online account.

4. Capacity charge and what happens if you exceed your agreed kVA value
This is a monthly amount charged by your local Distribution Network Operator (DNO) and is also known as the availability charge. This charge is based on the kVA value, or Maximum Import Capacity you agreed with your DNO to help maintain the electricity network. We collect this charge through your bill on behalf of your DNO.

To calculate your capacity charge, divide the kVA units by the number of days in the billing period. This should equal the kVA value you agreed with your DNO.

An excess capacity charge will be applied to your bill if you go over your agreed kVA value. You can contact your DNO at any time to check your connection agreement and to let them know if there’s a change in your business energy requirements.
