Designing your connection

After you submit your application and pay your application fee, we will begin designing your connection using the standard planning data and programme details you provide.

Take a look at what happens at the point of 'clock start'.

Your account manager and our engineering experts will work with you to design your connection to the network. We will conduct studies to understand the work required to facilitate your connection, whether that’s extending existing substations or building new ones.

These studies might find that your connection interacts with another connection that’s in progress. If this happens, we will discuss what this means for your project. These designs and plans will inform the offer sent to you by the Electricity System Operator (ESO). Once this is signed, we will start working towards your connection date.

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

  • Are you ready to provide your detailed planning data after you sign your offer?
  • Do you have any crucial milestones that may impact your connection programme, such as Development Consent Orders or a Financial Investment Decision confirming that your company has given us their consent to proceed?
  • Do you need a back-feed date agreed?
  • Are you ready to agree your securities and connection cost?

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