The ongoing geopolitical tensions including the Middle East have impacted the energy industry due to the key trade routes being disrupted. The wholesale energy market will be affected and so do the other charges being governed by the main authorities managing energy in the UK. As an energy supplier, we want to keep you informed. Recent updates mean some costs are changing, and this may affect your bills.
Energy prices remain uncertain. Alongside wholesale costs, network charges are also rising. One key charge is Transmission Network Use of System (TNUoS). This helps fund the UK’s electricity transmission network.
What’s changing this year?
The National Energy System Operator (NESO) has increased several transmission charges for the new charging year starting 1 April.
This reflects:
- Investment in grid upgrades
- Increased system demand
- Ongoing transition to low-carbon energy
As a result, we will be applying updated prices to remain fully compliant with industry regulations. See what impact ongoing geopolitical tensions can have on energy prices.
What are TNUoS charges?
TNUoS charges recover the cost of building, maintaining, and operating the high-voltage electricity transmission system across Great Britain.
These costs support:
- Grid infrastructure upgrades
- System reliability
- Connection of new generation sources
Charges are set every year and vary by location and demand. See the updated notification of changes.
Who do these charges apply to?
TNUoS charges mainly apply to:
- Electricity suppliers (based on customer demand)
- Generators (based on capacity)
- Large directly connected users
For most businesses, these costs are included within your electricity bill rather than charged separately.
How are charges calculated?
Charges depend on:
- Your location (charging zone)
- Your electricity usage
- Time of demand (especially peak periods)
Energy suppliers are charged based on actual demand. These costs are then reflected in customer tariffs. NESO publishes updated tariffs each year by 31 January, with changes taking effect from 1 April.
What does this mean for your business?
You may see changes in your energy supply costs from April onwards. The impact will vary depending on your usage and contract terms.
If you are on a fixed contract: Prices may stay the same until your contract ends. See terms and conditions of your energy supply contract.
If you are renewing or on flexible rates: Updated charges may already be included in new quotes
If you are a new customer: You will be getting the energy supply as per updated charges.
