Exclusive to Green Star Energy, the only energy tariff that provides complete peace of mind.

Unlimited tariff:

  • A made to measure plan - bespoke price based on your energy consumption

  • Lock in the price- 12 month contract

  • Flexible fuel choices  -  dual fuel or electricity only

  • Easy to budget - a fixed amount, no matter how much you use

  • No surprises - no unexpected high energy bills so you can turn up the heat without the worry

Choose a different tariff if:

  • You are looking for a gas only tariff

  • You do not want to fix your bills for 12 months

  • You have a prepayment meter 

  • You don't want to pay by Direct Debit

How does this product work for you?

  1. Typically your home uses more energy in winter and less in summer. We equalise your consumption to give you a flat monthly rate, fixed for 12 months.
  2. Payment must be made by monthly Direct Debit and you must receive paperless billing through our online account. We also ask that you provide monthly meter readings.

Our commitment to you:

Green Star Energy is committed to treating our customers fairly

We will do our best to treat all of our customers fairly, at all times.
