Invoices for medium to large-scale energy users often contain a degree of complexity and industry jargon that make them difficult to decipher. e4b has produced the following guide to help demystify your energy account.

A significant percentage of energy invoices are found to be in error due to the inherent complexity of bills and various systems issues within the National Electricity Market and individual Retailer organisations. We check the integrity of your energy invoices as part of our Manage e4b service to ensure that you are not being over-charged.
