Our response to coronavirus

Find out how we're working to keep the electricity and gas flowing reliably throughout the outbreak.

Building the connection

Before building, we will do more detailed designs and surveys to organise the contractors and equipment, and agree on-site responsibilities with you.

After this, we will start building your connection in line with your construction programme. We will monitor the milestones with you, through regular progress updates with your account manager.

We know that during projects things change which is why it’s important to keep us updated. In the event you need to amend your contract, you can submit a modification application to the Electricity System Operator (ESO).

Due to the COVID-19 pandemic you may have uncertainties about your connection application or are considering modifying your application. Please take a look at our Frequently Asked Questions to assist you with any concerns you may have.

Customer checklist

  • Have you agreed the regularity of face to face progress updates?
  • Have you had a kick-start site visit with us and our contractors?
  • Have you read and understood your construction agreement?

If you have answered no to any of these questions, please make an enquiry, we’re here to help.
