Your electricity supply type

You can identify your electricity supply type by looking at your current bill. Your Meter Point Administration Number (MPAN) or supply number will be shown as in the diagram below.


If the first two numbers in the top left-hand box are 00 then you have a Half-Hourly meter. Any other numbers mean you have a non Half-Hourly meter.

The meter allocated to your business will depend on your energy use, the type of business it is, the equipment it uses, and the site. Don’t worry – we’ll help you understand everything about your supply type and the obligations that go with it.
