Those without a smart digital meter must submit a meter reading once a year. Veitur sends a notification to the registered contact person. If you have recently added a new device that uses a lot of energy, for example a Jacuzzi or an electric car, it is a good idea to submit a meter reading more often to prevent you from getting a large bill when you pay for actual usage.
Those who have smart meters do not need to send a reading, it is regularly sent automatically to Veitur.
