    Okay, so here's the technical part. Electricity is delivered through the National Grid, from wherever it is generated. Your green energy is not supplied directly to your home but is fed into the National Grid, replacing traditional (brown) energy. When you switch to green energy, we will buy green electricity on your behalf. As more people opt to buy green energy, the supply of clean sustainable energy available on the National Grid increases and the demand for fossil fuel electricity diminishes.

    Distribution via the National Grid ensures that we can offer the same guarantee of uninterrupted supply, and that the reliability and quality of your electricity remains constant, as regulated by Ofgem (Office of Gas and Electricity Markets).

    You may not have heard of us before because we don’t advertise. This is actually good news for you because by avoiding the huge costs of advertising we are able to keep our prices as low as possible! But don’t worry no matter how big or small your electricity company, we are all regulated by Ofgem, and your electricity is delivered through the National Grid, guaranteeing you a reliable supply.

    The easiest and most hassle-free way of paying for your bills is by Direct Debit. We offer both variable and fixed monthly Direct Debits. Give us a ring on 0800 783 8851 if you'd like to discuss which would be best for you.

    Firstly, if you really are using more electricity than you expected check what is currently in use or any new appliances you have introduced since you last had a bill, alternatively we may not have had a reading for some time and had to estimate the amount of electricity you have used. If we get that wrong you may end up paying too much or too little for your electricity. We don’t want to over or undercharge our customers so we regularly ask our customers to send us a reading (at least once a quarter) but you can send them as often as you like. Regular readings keep your bill up to date so you only pay for the electricity you use.

  • Yes. Obviously all our electricity is sustainable as you know, but the volume of biogas in the grid is very small and not really commercially available. However, our customers repeatedly asked why we didn't have a dual fuel offering. So we listened.

    The injection of biogas into the grid is becoming a very real possibility. Some of our customers use gas, that's a fact, any position we adopt won't stop them using it as a heating and cooking fuel, If we want to take advantage of biogas when it is finally introduced we need to be in the gas market now - if we're not we'll miss the boat!

    Here at green energy, we want sustainable energy to become mainstream. So, not only can our prices compete with other green utilities, but with the Big Six 'brown' suppliers, too. That way, we hope there'll be no obstacles to making the switch.

    You might be wondering how our prices can be so low. We've managed this by keeping all of our costs to a minimum. In particular, we've made sure our prices are not loaded with the hidden cost of advertising and marketing. We think our business can speak for itself.

    You should notify us in the event that your supply or billing address changes. If you provide us with your new supply address we can continue to provide green electricity to your new home or business premises. If you move house within three years of becoming a customer, but continue to use green energy as your supplier, you will retain any shares that you received on first joining us.

  • Sure. Direct Debits are paid from your account every month, but we send you a bill each quarter if you are on a fixed direct debit to let you know how much electricity you have used and as a statement of your account. We consider quarterly billing to be greener as it saves on paper. If you want extra brownie points why not opt for paperless e-billing and save using any paper whatsoever!

  • Once you have joined, a meter reading is taken. Subsequent readings are done at least once a year. However, if at any time between readings you become concerned over the accuracy of the estimates, you can take a meter reading yourself, and send it to us. We will then review your estimates.

  • Don't worry. The entire industry is regulated by Ofgem, which assures that customers of all energy suppliers receive a reliable and uninterrupted supply. Green Energy UK is required by law to comply with strict regulations that ensure customers get value for money and a reliable service. Because of the Ofgem (Office of Gas and Electricity Markets) regulation, even if an energy company were to fail, your power supply cannot be cut off. You would continue to be supplied electricity from the National Grid, and you would be allocated to another energy supplier and could then choose whether to stay, or to change to another supplier.

  • In the event that your power supply fails you should contact the regional distribution company in your area. They are responsible for the maintenance of the power lines etc. in your neighbourhood, and ensuring that your power supply is maintained. The emergency number for your region is printed on your bill. Look up your distributor by entering your postcode below.

  • No, as a domestic or small business user you can settle your account and change supplier at any time. If you do not remain with us for a minimum of three years from the switching date you will forfeit any shares you received on becoming a customer. Please see the free shares page on our website or contact us if you want more details

  • Your initial direct debit is based on national average data. The monthly direct debit amount is reviewed after being a customer for 4 months, your account is then reviewed every 12 months. But if you have any concerns over the amount, you can take a reading at any time and request a review. One of the advantages of monthly direct debits is that it smooths out the cost of the more expensive winter months with the cheaper summer months.
