Calculate how the incoming TNUoS charges will impact your bill
In September 2025, The National Energy System Operator (NESO) released their forecast for upcoming changes to Transmission Network Use of System (TNUoS) charges, to be implemented between the financial years 2026 – 2030. NESO seeks to raise ~£3.5bn in charges through customer bills to cover the costs of upgrading and expanding the existing transmission network. This will mean a significant increase in cost to customers on their standing charges.
This tool has been developed in partnership with the NFU to help you quickly understand how the proposed changes could affect your business’ energy costs, using a few simple details from your bill to give you a personalised estimate. The information gathered through you completion of the calculator will support the NFU’s efforts lobbying the government.
