    Here at green energy uk, 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.

    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 uk, 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).

  • Whatever your query, be it big or small, our team will be happy to hear from you. Not only are we firm believers in good-quality, human customer service, but we are also given regular check-ups by Ofgem (the government body in charge of the energy industry) to ensure we're looking after you properly. So, for problems about your energy supply, or the service you’re receiving, don’t hesitate to call 0800 783 8851.

  • 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 uk as your supplier, you will retain any shares that you received on first joining us.

  • 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 are 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.

  • 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.

  • Meter reading video with Chris
    Digital single register meter

    Write the numbers down as you see them from left to right ignoring the figure furthest to the right marked 0.1 in the red section.

    Digital dual register meter

    The upper register is the off-peak or night register and the lower is your normal-rate day meter. Record the numbers from left to right ignoring the final figure marked 0.1

    Dial meter

    Read the dials from left to right, ignoring the dial marked 1/10. When the pointer is between two numbers, always note down the lower number, for example, if it is between 9 and 0, write down 9.

  • All energy usage is charged by the kilowatt-hour, or unit, plus a standing charge to 'distribute' energy to your home. Making price comparisons can be difficult and confusing, so we've tried to make it simple and transparent. Tariffs must be published and you can view ours on the simple tariffs page of this website.

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

  • 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.

  • 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.

  • Yes. And its green gas. Obviously all our electricity is sustainable as you know, but now our gas is 100% green too.

    Gas like electricity is a homogenous product when delivered to consumers but the gas we put into the grid is not. Green gas, or biogas, is sourced from processes like Anaerobic Digestion (AD), where waste that would otherwise leak methane into the atmosphere (methane is 20 times more potent than CO2), is processed into biogas to be used as fuel. All our gas will come with a Green Gas certificate under this independent scheme

  • 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.
