Energy Comparison FAQ

  • What information do I need to switch to a better deal?

    Most people can switch using just their postcode and a few basic details, most of which can be found on your energy bill – such as how much you spend or the amount of energy you use. If you don’t have this information to hand you can still switch using our usage estimator. Or give us a call on 0800 634 5185 and we will do our best to help you.

  • Will I be charged for this service?

    No, we do not charge you for switching with us, and there are no hidden surcharges. We show you the best available rates from all suppliers in your area. You may then choose the one that suits you. Switching your provider does not cost anything, and it will save you money.

  • Will my electricity or gas supply be interrupted?

    No, there will be no interruption whatsoever and your provider will use your existing wires and pipes. 

  • How are the service ratings calculated?

    Our service ratings provide an easy reference to the level of service a supplier provides. The easy-to-understand star system is represented as follows:

    1 Star - Poor

    2 Stars - Below Average

    3 Stars - Average

    4 Stars - Good

    5 Stars - Very Good

    The ratings are calculated from complaint levels received by Consumer Focus, the independent market watchdog. The ratings also take into account call centre hours and availability of suppliers’ internet services and special offers. Deductions are made if the energy regulator OFGEM has imposed recent fines.

  • Will I need to contact my old supplier to switch to a new provider?

    No, your old supplier will be contacted by your new supplier, who will organise the switching process on your behalf. You should provide your new supplier with a final meter reading however, so they can organise a final bill and close your account with your old provider.

  • I would like to pay by Direct Debit, will I need my bank details?

    In some instances you may request a paper Direct Debit form which will be sent by your new supplier. You can then fill the form out with your bank details, and return it to them. However, we do recommend that you complete your Direct Debit forms online as it is less time-consuming and the information is received and stored securely.

  • If I don't know my exact recent energy usage will I still be able to use your calculator?

    Yes you can. We have provided a simple usage estimator which provides a rough estimate based on the size of your property. Generally smaller flats will be lower energy users, larger flats and houses will be medium users, and large houses will be high users. Or if you prefer to go into greater detail, our detailed usage estimator allows you to enter more specific details regarding usage, such as how many bedrooms you have, the number of occupants in your home, and the type of energy you use to cook.
