Green Star Energy in a nutshell
- Green Star Energy is one of the newest electricity and gas suppliers on the UK market.
- It is also one of the cheaper suppliers on the UK market thanks to the discounts it offers.
- But Green Star Energy is too new to establish its customer care and service reputation.
Green Star Energy was launched last year
Green Star Energy was founded in mid-2013. It is one of the newest energy suppliers on the UK electricity and gas market. The supplier is part of the Just Energy Group, an energy provider in North America (United States and Canada). Green Star Energy is still a small supplier, with 138 customers at the end of 2013.
Green Star Energy’s unknown fuel mix
Ofgem, the energy regulator, is still reviewing Green Star Energy’s fuel mix. It is likely to rely significantly on natural gas and renewables, given Just Energy’s focus in North America.
Green Star Energy current prices
Green Star Energy is currently one of the cheaper energy suppliers in the UK. This is due mostly to dual fuel, direct debit and online account management discounts. Indeed, when taking electricity and gas prices separately, Green Energy Star prices are neither the cheapest nor the most expensive. The following uses the standard tariff comparison rate (3,200 kWh annual electricity usage and 13,500 kWh annual gas usage) applied to London offers to give you an idea of estimated annual Green Star Energy costs.

Green Star Energy customer reviews
Green Star Energy complaints performance
Unfortunately, the only complaint Green Star Energy received and resolved over 2013’s last quarter is not sufficient to establish trends on how efficient the electricity and gas supplier is with regards to complaints performance.
What customers say about Green Star Energy
Similarly, given its recent arrival on the UK electricity and gas market, too few customer reviews are available online to establish how well Green Star Energy fares in terms of billing, payment options, accuracy of charges or customer care.
