The business, formerly known as Jersey Gas, says the change should help customers pay bills at the Post Office more efficiently.

“Previously customers would reference their individual Post Office number to make payments; however, going forward, these numbers will no longer be recognised,” said IEG.

“Customers will now need to present their paper bill at the Post Office, which will detail a unique invoice number. To make this process quicker and easier Island Energy has introduced barcodes that will contain the invoice number for Post Office cashiers to scan. Customers who make regular smaller payments to support their budgeting can reuse the same invoice number several times.”

IEG said the change was prompted by a new internal system and will only affect those you pay their bills at the Post Office.

“Customers will still have other payment options, although Island Energy recommends that all customers use direct debit payments as these enable customers to spread the cost of heating over the year. Using direct debit alongside e-billing gives easy access to bills, as well as being a greener solution as it avoids paper bills.”
