More information

*With our Double Gold tariff or Green Fixed tariff (available only as part of the 3 or 4 service bundle - Bill Protector and Cashback Card excluded. Boiler & home cover is also excluded for tenants) new customers will be on tariff where the electricity comes from 100% renewable sources like wind, solar and biomass. The renewable electricity we sell for these tariffs is backed by Renewable Energy Guarantee of Origin certificates which allows Ofgem to verify the source of a supplier's electricity.
