Business Electricity Non-commodity Charges :
Business electricity non-commodity charges, also known as non-energy costs or third-party charges, are the parts of your electricity bill that are not related to the actual wholesale cost of electricity itself.
These charges have become one of the largest parts of many UK business energy bills. Even if wholesale electricity prices fall, your final bill may not reduce as much as expected because non-commodity charges can continue to rise independently.
2026 Warning: From April 2026, several electricity non-commodity costs are increasing, including transmission, balancing, policy and infrastructure-related charges. The exact impact will depend on your meter type, region, contract structure and consumption profile.
At Utility7, we help UK businesses understand their electricity bills, compare contract options and identify practical ways to reduce unnecessary costs.
What Are Business Electricity Non-Commodity Charges?
Non-commodity charges are costs added to your electricity bill by network operators, regulators and government-backed schemes. They help cover:
- Maintaining and upgrading the electricity network
- Supporting renewable and low-carbon energy schemes
- Balancing the national grid in real time
- Environmental and social policy costs
- Funding low-carbon infrastructure, including nuclear and renewable support schemes
These charges are mostly regulated and are broadly similar across suppliers. However, the way suppliers pass them on, structure them within contracts, and apply margins can vary.
They are usually divided into two main categories:
- Network and system charges
- Policy and environmental levies
Main Non-Commodity Charges: 2026 Update
| Charge | Full Name / Meaning | Purpose | 2026 Update |
| TNUoS | Transmission Network Use of System | National Grid transmission network maintenance and upgrades | Charges have risen sharply from April 2026. Average increases are around 60% to 64%, depending on region, meter type and charging band. |
| DUoS | Distribution Use of System | Local electricity distribution network costs, including wires and substations | Regional increases apply, with many businesses seeing the impact through standing charges and unit rates. |
| BSUoS | Balancing Services Use of System | Real-time electricity system balancing | Fixed seasonal rates for 2026/27: £13.74/MWh for summer and £12.49/MWh for winter. |
| RO | Renewables Obligation | Support for renewable electricity generation | The cost continues to be passed through as part of electricity supply charges. |
| CfD | Contracts for Difference | Funding low-carbon electricity generation | Pass-through reconciliations can occur after the original billing period, depending on supplier and contract structure. |
| FiT | Feed-in Tariff | Support for small-scale renewable generators | Generally treated as a unit-rate charge and passed through by suppliers. |
| CCL | Climate Change Levy | Environmental tax on business energy use | The main electricity rate increases to 0.801p/kWh from April 2026. Some businesses may qualify for reduced rates or exemptions. |
| Capacity Market | Capacity Market | Ensuring security of electricity supply | Applies mainly to half-hourly metered sites, with pass-through reconciliation depending on supplier contract terms. |
| Nuclear RAB | Nuclear Regulated Asset Base | Funding new nuclear infrastructure, including Sizewell C | Levy started December 2025. Rate increased to £4.683/MWh for Q2 2026, updated quarterly. |
| EII Support Levy | Energy Intensive Industries Support Levy | Funding support for Energy Intensive Industries | Increased from April 2026 as EII relief expands; non-EII businesses may carry more of the shared cost. |
| AAHEDC | Assistance for Areas with High Electricity Distribution Costs | Supports higher distribution costs in Northern Scotland | Small socialised levy, generally stable. |
| Standing Charge | Fixed daily charge | Fixed daily cost for supply, metering and network-related charges | Some businesses may see higher standing charges as certain network costs are increasing. |
3 Big Changes to Watch in 2026
1. TNUoS Charges Rise Sharply
Transmission Network Use of System charges have increased significantly from April 2026. While some businesses may see moderate increases, others may be affected more heavily depending on their profile, meter type and location.
This is linked to major investment in the UK electricity transmission network, including upgrades required for renewable generation, grid capacity and the wider energy transition.
2. Nuclear RAB Levy Goes Live
The Nuclear Regulated Asset Base levy is a new charge introduced to help fund new nuclear infrastructure, including Sizewell C. It started appearing on business electricity bills from December 2025.
The Q2 2026 rate is £4.683/MWh, with the rate updated quarterly. Businesses should be aware that this is a new additional cost within electricity bills.
3. EII Support Levy Increases
The Energy Intensive Industries Support Levy has increased as the government expands relief for eligible high-energy-use industries. This support helps energy-intensive businesses, but the cost is shared across other electricity consumers.
For non-EII businesses, this means another policy-related cost to monitor within electricity contracts.
Why Are Non-Commodity Charges Increasing?
Non-commodity charges are increasing due to a combination of network investment, policy costs and system pressures. Key reasons include:
- Major upgrades to the National Grid
- Greater demand from electric vehicles, heat pumps and electrification
- More investment in renewable and low-carbon energy
- New funding mechanisms for nuclear infrastructure
- Higher system balancing requirements
- Inflation and regulatory cost adjustments
- Expanded support for energy-intensive industries
As a result, businesses should not only look at the wholesale electricity rate when comparing commercial electricity prices. The full contract structure, standing charge, pass-through terms and non-commodity treatment are equally important.
How to Reduce Business Electricity Non-Commodity Charges
You cannot remove these charges completely, but you can reduce their impact with the right strategy.
1. Choose the Right Tariff
Your tariff structure can affect how non-commodity charges are applied. Fixed-rate vs pass-through energy tariffs each have different implications — fixed-rate contracts can offer budget certainty, while pass-through contracts may offer more transparency but expose your business to future movements.
2. Review Your Meter Type and Load Profile
Half-hourly meters, smart meters and correct load profile classification can help businesses understand when and how electricity is being used. Better data can support better contract decisions.
3. Manage Peak Demand
Reducing consumption during peak periods can help limit exposure to certain network and system costs. This is particularly relevant for businesses with high daytime or evening usage.
4. Improve Energy Efficiency
Reducing overall consumption remains one of the most effective ways to reduce both commodity and non-commodity costs. Practical measures include:
- LED lighting
- Smart heating and cooling controls
- Voltage optimisation
- Equipment scheduling
- Staff energy-awareness processes
5. Check CCL Relief or Exemption Options
Some businesses may qualify for Climate Change Levy reductions or exemptions, including those with Climate Change Agreements or eligible business-use circumstances. Businesses should review their eligibility carefully rather than assuming all energy contracts are treated the same.
6. Check EII Eligibility
Energy-intensive manufacturers and qualifying businesses should review whether they are eligible for support under EII-related schemes. From April 2026, eligible businesses may receive stronger relief against certain network costs.
7. Prepare for BICS
The British Industrial Competitiveness Scheme is expected to support over 10,000 eligible manufacturers from 2027, with additional support linked to costs that would have applied from April 2026. Businesses that may qualify should monitor developments and prepare evidence early.
8. Review Your Contract Before Renewal
Waiting until the last minute can reduce your options. Reviewing your contract early gives your business more time to compare fixed and flexible options, check pass-through terms and avoid being rolled onto poor renewal rates.
9. Work with an Expert Broker
A specialist broker can help assess the full bill, not just the headline unit rate. This includes:
- Standing charges
- Contract length
- Supplier margin
- Pass-through terms
- Meter type
- Consumption pattern
- Renewal timing
- Non-commodity exposure

Frequently Asked Questions : Business electricity non-commodity charges
Q: Are non-commodity charges the same with every supplier?
Many non-commodity charges are regulated or set externally, so the base charges can be similar across suppliers. However, suppliers may pass them on differently depending on the contract type, margin and billing structure.
Q: What is the Nuclear RAB levy?
The Nuclear RAB levy is a charge designed to help fund new nuclear infrastructure, including Sizewell C. It started from December 2025 and is updated quarterly.
Q: Can I avoid business electricity non-commodity charges completely?
No. Most businesses cannot avoid them completely. However, you can reduce their impact through better contract structure, lower consumption, smarter usage timing and proper bill review.
Q: What is the difference between fixed and pass-through energy tariffs?
Fixed vs pass-through energy tariffs — a fixed tariff gives more price certainty because key costs are included in the agreed rate. A pass-through tariff can be more transparent but may expose your business to future increases in non-commodity charges.
Q: Can CCL be reduced?
In some cases, yes. Some businesses may qualify for reduced rates or exemptions, including those covered by Climate Change Agreements or other eligible circumstances.
Q: What is BICS?
The British Industrial Competitiveness Scheme is a government support scheme expected to help over 10,000 eligible manufacturers from 2027. It is designed to reduce electricity cost pressure for qualifying businesses.
Q: Why should I review my electricity contract early?
Reviewing early gives your business more time to compare prices, check contract structure and avoid poor renewal terms. It also helps you understand how 2026 non-commodity changes may affect your future bills.
Q: How can Utility7 help?
