Welcome to our monthly update
At Energy Costs Managed, we pride ourselves on being energy consultants with a difference.
Unlike many in our industry, we go beyond just procuring electricity, gas and water supply contracts, in this months round up, we cover changes to wholesale energy prices over February, volatile pricing and TNUoS charge increases from the 1st April 2026 and how these could impact your business going forward and much more.
February Overview
In February 2026, wholesale electricity and gas prices have remained volatile. Ongoing concerns surrounding the conflict between Iran and the United States, and its impact on neighbouring countries, have led to significant price fluctuations. We continue to monitor the situation closely on behalf of our clients and will provide as much communication and support as possible. As we start March 2026, wholesale gas prices have seen some significant price increases this morning - 2nd March.
Wholesale Energy Prices
Wholesale gas prices have increased during February, including the morning of 2 March, in some cases quite markedly. Wholesale electricity prices have eased slightly; however, given the current conditions in the wholesale gas market, it remains to be seen whether this will affect power prices in the days ahead.
If you’d like to know more about how these prices will impact you and your business or would like to know more about when to look to renew your energy supply contract book a call with a member of our team today.

Upcoming TNUos Charge Increases on the 1st April 2026
NESO (National Energy System Operator) has confirmed that on average a 64% increase in TNUos Charges for 2026/2027 starting from the 1st April 2026.
The increase is being driven largely by continued and accelerated investment in national grid infrastructure. Substantial upgrades and expansion are required to accommodate growing electricity demand, connect new renewable generation, and strengthen overall network resilience. While these developments are critical to supporting the UK’s long-term energy strategy and transition to net zero, the associated costs are recovered through network charges such as TNUoS.
For business energy customers, this will translate into a notable rise in non-commodity costs and will be passed on particularly in standing charges. As these charges are passed on and applied regardless of consumption levels, organisations may see higher overall electricity costs even if usage remains unchanged. We recommend that businesses review their current contracts, budgets and energy strategies ahead of April 2026 to understand and mitigate the potential financial impact where possible.
