MCC stands for Meter Configuration Code. It's a code that is used to describe the type of meter (or its functionality) you have. You can view your MCC at the top right-hand corner of your bill.
For example, a 24-hour meter has a code of MCC01. A day/night meter has a code of MCC02.
Your smart meter is configured differently depending on the type of smart plan you've chosen, and the frequency of the data collection from your smart meter.
For example, if you're on our Standard Smart Tariff (SST), then your meter configuration is MCC16. This means your consumption data is collected every two months and displayed in day, night and peak intervals.
If you're on a half-hourly Time of Use Tariff (e.g. Free Time, Discount Weekend or an EV tariff) then your meter configuration is MCC12. This means your consumption data is collected every half hour and displayed in day, night and peak intervals. This also means you can view your half-hourly usage information on your online account.
