Once the meter is installed we maintain the right to monitor your supply for fair usage and continued eligibility for the electric vehicle tariff however you are responsible to ensure that your electricity supply switches at the appropriate time by carrying out regular checks of the switching times of the meter.  If you have any concerns you should contact our customer service team immediately on 687675

Domestic customers are eligible for the electric vehicle charging tariff subject to meeting the criteria. Not all customers premises may be suitable for the installation of an electric vehicle meter. This may be due to the proximity of the electric vehicle parking arrangements or the existing electricity supply to the property.
