  6. Your metering arrangement


    1. Your export meter must be located, where reasonable, in an accessible location. This means your meter must be in a position where it can easily be read without the use of any equipment (e.g., a ladder or tools). If your Installation is in a rural location, it also means that the building in which the export meter is installed is accessible on foot from a public road; 

    2. If we consider, following a visit by one of our metering agents/contractors, that your export meter is not in an accessible location, we will have the right to require you to pay a reasonable charge. This charge will be based on the additional costs payable to our agent for gaining access.

      Metering regulation

    3. You must ensure that the export meter complies with the Metering Regulations;

    4. You will be responsible for ensuring that the export meter is operating properly;

    5. You should speak to us if your export meter (or any meter relevant to SEG payments being made) is found to be broken or recording in error. For more information see the SEG Generator Guidance.

      Your export meter readings

    6. You agree to provide us with accurate export meter readings on the Registration Date, the Agreement end date, and at our reasonable request at any time between the registration date and the Agreement end date;

    7. To pay you for the energy you export, we need readings from your export meter. Where possible, we will take remote readings from your smart meter. If that is not possible, we will send you a notification to ask for a reading. Each notification will explain how to provide the reading and the date we must receive the readings by;

    8. All export meter readings must be provided in accordance with the procedures described in the Confirmation or such revised procedures as we may reasonably introduce and notify you of. If you do not provide us with a particular export meter reading, in accordance with the relevant procedure, by the applicable reading date, we will have the right to suspend payment for the period in question and not pay you until we have received from you a fully updated, valid export meter reading.

      Access to your meters

    10. We will have the right to carry out verification checks on a frequent basis;

    11. If our metering agents/contractors are unable to gain access to your site for the purposes described above, we have the right to suspend any payment until we have been able to gain access and verify the accuracy of your export meter readings;

    12. We have the right to perform, or ask our metering agent/contractor to perform, an accuracy check to validate any export meter reading you submit. If this check finds that your readings are inaccurate or abnormal, then we will contact you to request proof of the accuracy of the export meter reading. If this occurs, you have the responsibility to provide evidence in order for us to accept the export meter reading. Evidence could include a dated photo, or providing physical access to Bulb and/or our metering agent/contact to verify your meter in person. If we are not satisfied as to the accuracy of the export meter reading, we will have the right to suspend the relevant payment for the period in question and not pay you until we have received from you fully updated, valid export meter readings.

      Meter running backwards

    13. If the import meter at the site of your Installation is running backwards, you must contact us and your import electricity supplier immediately. If you are not the occupier of the site, you must ensure that the occupier contacts their import electricity supplier immediately.

  7. Grid Connection Arrangements

    1. You must ensure that the Distribution Network Operator has been notified and that you comply with any requirements relating to ongoing use of the grid connection;

    2. If a connection agreement with the network operator, governing the export arrangements, is not already in place, then by exporting electricity to us under this Agreement, we are required under electricity industry rules to ensure that you enter into a standard connection agreement with the network operator. In this case, we will act on behalf of your network operator to make an agreement with you. We will speak to your network operator and get an MPAN on your behalf. The agreement is that you and your network operator both accept the National Terms of Connection (NTC) and agree to keep to its conditions. This will happen from the time that you enter into this Agreement and it affects your legal rights. The NTC is a legal agreement. It sets out rights and duties in relation to the connection where your network operator delivers electricity to, or accepts electricity from, your home or business. If you want a copy of the NTC or have any questions about it, please contact the Energy Networks Association (

  8. FIT Export payments

    1. If your Installation is receiving FIT Payments, you will have made an initial choice about whether to receive the export payment or to sell exported electricity on the open market. Your decision is on the CFR. You will be unable to change your first choice until at least the first anniversary of your participation in the Ofgem FIT scheme.  After that date, you are permitted to change your selection to opt in or out of the FIT scheme, but no more than once every 12 months. If we are you FIT licensee, we will record your opt-in or opt-out decision on the CFR. 

    2. If an Installation is participating in the SEG scheme, it must not also be receiving FIT Export payments. By entering into this Agreement, you agree to accurately inform Bulb:
