Bills & payments

GnERGY customers had the options to pay bills by monthly Direct Debit or via quarterly payments on receipt of them.

To avoid inaccurate estimated bills, we recommend that you submit a meter reading every month, no matter which energy supplier you are with. If you provide regular meter readings your account shouldn't fall into arrears.

Energy mix

While customers with GnERGY were moved on to 100% renewable electricity supplier Bulb Energy following its collapse, the former certainly wasn't the greenest energy provider around in its time. Its fuel mix was heavily reliant on coal and natural gas for its electricity. In fact, the supplier’s use of coal was the highest of any UK energy provider at 34%, more than six times the UK average at the time of its closure. At just 16.7%, GnERGY’s use of renewables was half the national average at the time.

Warm Home Discount Scheme

The Warm Home Discount scheme is a government-backed scheme to help those at risk of fuel poverty with their energy bills during the winter months. Eligible consumers can get up to £140 discounted from their energy bills from October to April.

GnERGY Energy didn’t participate in the Warm Home Discount scheme as it is only available to suppliers with over 200,000 customers. However, as one of the largest green energy suppliers around, Bulb Energy does offer the scheme to its customers.
