I signed up today for the So Turtle tariff. Good customer service during my enquiries. Based on 6000kWh split 2400kWh day and 3600kWh Economy 10. 12 month fixed contract, monthly direct debit. Personal projection £872 a year. Standing charge 22.05p/day, Day rate 16.02p and cheap rate 11.29p. £5 early exit fee. This was the best tariff I could find of any suppliers at the current time.
