Utilita Energy (usually just branded under the single term) was established by Bill Bullen in 2003. They have since emerged as one of the leading solutions for smart pay as you go energy, now with over 450,000 customers. They install every customer with a free smart meter on a competitive tariff. Through their Price Commitment they aim to beat the Big Six on pre-payment tariffs. For those interested in joining, it usually takes 4 weeks to switch suppliers. They do handle the process fully on your behalf. When sampling a local postcode, they offered the weekly tariffs of Premium E7 (£11.45), Premium Energy (£20.25), Smart E7 (£11.47) and Smart Energy (£20.21). These priced are based on average household consumption.
