Contacting your energy supplier

Do you need to reach your electricity and/or gas supplier? Here is all the information you need.

Contacting your energy supplier online

All electricity and gas suppliers offer the possibility of managing your account online. Concretely, this means:

  • signing up to a dual-fuel, electricity or gas plan online;
  • submitting meter readings through your online account;
  • contacting customer service via email.

Accepting to contact your energy supplier online enables suppliers to make significant savings on their operating costs. In turn, most suppliers offer cheaper tariffs for online account management.

Contacting your energy supplier by telephone

Zog Energy is the only energy supplier (gas only) without a customer care telephone number. However, energy suppliers’ customer service lines operate at very different times. The table below lists energy suppliers with their customer care numbers and operating hours, so you know when to call.
