Launched in 2012, the supplier originally offered electricity-only tariffs, but now supplies gas, making it a dual fuel energy supplier.
With an easy-to-use online account management and competitive, straightforward pricing, iSupplyEnergy offers customers on both prepayment and credit meters an alternative to the big six.
And, with a UK-based call centre, customers can get customer service in whichever way they prefer — via telephone or through iSupplyEnergy's online account portal.
iSupply price rise
In March 2018, iSupplyEnergy announced a price change of 7.5%, affecting its variable rate tariff customers.
The supplier commented that only 9% of its current customers would be hit by the price rise; however, all customers currently on fixed plans will eventually be rolled on to this more expensive tariff when their fixed rate contract ends, unless they switch energy supplier.
