New directly connected demand applications

Applications can be submitted up to 23:59 21 March 2025. They must be 'clock started' by 23:59 4 April 2025.

To achieve a 'clock start', customers must pay the application fee, provide any justification requested and answer clarification questions by 4 April 2025. A 'clock start' is the date on which the application and Data Registration Code (DRC) data submission is deemed technically competent, and the fee is paid.

Customers must provide their Connection Application Number, Invoice Number and Proof of Remittance to NESO via email by 4 April 2025. We need time to process payment therefore advise payment at least 48 hours in advance of the deadline to allow for bank transfer time.

Note: standard invoices may say 30-day terms but customers must pay by the 4th April deadline, which may be <30 days depending on when application were submitted. Effectively, dates stated from Ofgem supersede standard timelines. Urgent queries can be sent to: box.customerservice@nationalenergyso.com
