Customer Service

Help things to go smoothly by doing the following:

  • It’s important that you continue to pay for your energy use and contact us immediately if you don’t agree with the amount on your bill.
  • Provide meter readings when requested so that you pay the right amount for the energy you use. That way you’ll avoid estimated bills which can lead to a build-up of credit or debit. The easiest way to provide your meter readings is through your online account or at If your meter is being read by one of our representatives, allow them reasonable access if it is needed.
  • If you have a prepayment meter, top up regularly so that your prepayment meter remains in credit. Even in the summer months when you might not use much energy, a standing charge still applies.
  • If you’re finding it difficult to pay your energy bill, please get in touch. There are various ways we can help, such as agreeing for your bill to be paid in manageable instalments, or by having a prepayment meter fitted, if it is safe and reasonably practicable to do so.
  • If you’re moving and we’re the supplier of your current or new home, let us know.
  • If you think your meter has developed a fault or if you can smell gas, get in touch immediately. The National Grid emergency number is 0800 111 999*.
  • In the event of a power cut, check to see if its just you, if its your neighbours too you can contact your local network operator by calling 105.
  • Do you think you may need extra help or support? Our Priority Services may be able to help to support your communication, safety and access needs. If you’re eligible you can choose to join our Priority Service Register free of charge.
