Understanding the impact of standing charge changes

02 December 2025

NFU members and NFU Energy customers can now use a free calculator to estimate the impact the TNUoS (Transmission Network Use of System) charge will have on their business.

The data collected will support the NFU’s call for greater recognition for farming within existing energy support schemes.

The government brought in support schemes to protect high-energy users against the sharpest of rises and currently don’t apply to most farming and growing businesses.

The NFU and NFU Energy are urging members to assess the impacts of increased standing charges as a series of three changes begin to take effect.

The increases, phased in from October 2025 to April 2026, could see charges rise sharply, putting significant pressure on high- and seasonal-energy users.

Not only will the calculator help you estimate the impact of the TNUoS charge on your business, but all data input will be anonymised and aggregated and will form an important part of the NFU’s lobbying work.

If you have your electricity bill on hand, it shouldn’t take more than 5 minutes to complete.

“Vitally, it will also help us build a picture to show just how extreme these cost rises are as we continue to take the issue to government.”

Help build evidence

The NFU is calling on the government to review the SIC (Standard Industry Classification) codes to better reflect the high energy users in our industry and to bring reforms to Ofgem’s Targeted Charging Review, which sets the bands on which the charges are based.

NFU President Tom Bradshaw said: “Spiralling energy costs, which are set to increase in April, are threatening the viability of farming and growing businesses. Some members are reporting increased costs of over £1 million, which simply is not sustainable.

“I would urge all businesses concerned about their energy costs to take advantage of the calculator to help them plan for the months ahead. Vitally, it will also help us build a picture to show just how extreme these cost rises are as we continue to take the issue to government.”

Clear, practical insight

Tim Crocker, managing director of NFU Energy, added: “Energy network charges are undergoing some of the most significant reforms we’ve seen in years, and these changes will affect how costs are distributed across the entire system. 

“For farmers and agricultural businesses, who often operate energy-intensive sites, understanding these shifts is essential. The TNUoS Charges Impact Calculator turns a complex policy change into clear, practical insight, helping businesses visualise what the reforms mean for them so they can take practical steps to mitigate the impacts and plan for the future.

“The anonymised and aggregated data from the calculator supports the NFU’s wider lobbying efforts for fairer outcomes for all farmers, protecting UK food production.”
