Help for low income families or those in debt

If you are having trouble paying your bill, you should let Green Star Energy know immediately by calling 0800 012 4510. The company says it will work with you to find a suitable payment plan.

One alternative which is often suggested if you are struggling with your energy bills is a pre-payment meter. Pre-payment meters let you pay for your electricity and gas upfront. The system is similar to a pay-as-you-go mobile phone. Pre-payment meters help you to pay back money you owe as well as stop you falling behind again. Green Star pre-payment meter customers buy credit at their local Post Office, PayPoint or PayZone.

As well as providing solutions to help you if you are struggling to pay your energy bills, Green Star Energy also publishes simple tips that can help you reduce the amount of energy you use in your home and therefore reduce your energy bills.

Green Star Energy recommends the following measures:

  • blue-bullet-pointReplace incandescent with energy-efficient compact fluorescent bulbs.
  • blue-bullet-pointTurn off electrical appliances when you leave the room or aren’t using them.
  • blue-bullet-pointMake sure your home is properly insulated.

Warm Home Discount Scheme

The government’s Warm Home Discount Scheme gives eligible people a £140 discount on their electricity bill between October and April. The Warm Home Discount Scheme payment doesn’t affect your annual Winter Fuel Payment or any Cold Weather Payment you might receive.

You are automatically eligible for the scheme if your energy company is part of the scheme and you get the Guarantee Credit element of Pension Credit. You may be eligible if your energy company is part of the scheme and you are on a low income or you get certain means-tested benefits.

For more information on the Warm Home Discount Scheme you can visit www.gov.uk/the-warm-home-discount-scheme/.
