Your Energy Bills with Luminus

In order to understand your energy bill, Luminus has provided an example on its website with explanations of all the items on your bill.
In general, your supplier sends you your invoices by post and you can choose the frequency of your payments (monthly, bi-monthly, or quarterly) as well as the amount you pay based on an estimate of your consumption.
At the end of the year, you will receive your year end invoice. It is based on a meter reading taken by a technician appointed by your distribution network operator (GRD). The year end bill will be adjusted based on the actual meter reading compared to the estimated amounts previously billed.
Therefore, if you have paid too much during the year, Luminus will reimburse you the difference, and vice versa.
