Quick Answer
Non-commodity costs are the charges included in business energy bills that do not relate directly to the wholesale cost of generating electricity or gas. Instead, they cover energy policy levies, environmental programmes and transport of electricity across the national grid. In the UK, these costs fund renewable schemes, maintain network reliability and support energy policy objectives.
What are non-commodity costs?
Non-commodity costs refer to the portion of a business’s energy bill that is not linked to the wholesale price of electricity or gas. While commodity costs represent the price paid for the energy itself, non-commodity charges cover the systems, regulations, levies and network arrangements that make the UK energy network function.
These charges help fund national infrastructure, renewable energy incentives, grid balancing mechanisms and carbon-focused environmental initiatives. They are regulated by government bodies and industry organisations and are applied across energy suppliers operating within the UK market.
For businesses, non-commodity costs cover a lot of the energy bill. Because they are influenced by regulatory decisions and infrastructure investment rather than wholesale market prices, they can change independently of energy generation costs.
Understanding these charges allows businesses to understand energy bills and anticipate potential changes.
Understanding the core non-commodity costs
Non-commodity costs encompass several policy-driven charges and network-related fees. These costs ensure that electricity can be generated sustainably, transported efficiently and delivered reliably to businesses across the UK.
Many charges originate from environmental initiatives and national energy infrastructure maintenance, such as running the electricity grid and balancing supply with demand.
Below are some of the key components that make up non-commodity costs.
Contracts for Difference (CfD)
Contracts for Difference is a government-backed mechanism designed to encourage investment in low-carbon electricity generation. The scheme provides renewable energy producers with long-term price stability by guaranteeing a fixed price for electricity generated from eligible sources.
If the market price for electricity falls below the agreed strike price, generators receive a payment to make up the difference. If the market price rises above the strike price, the generator returns the difference.
The funding for these payments comes from electricity suppliers through a levy that is ultimately reflected in business electricity bills. As more renewable projects enter the system, the impact of CfD-related charges can fluctuate depending on wholesale market conditions.
Renewables Obligation (RO)
The Renewables Obligation is one of the UK’s long-standing renewable support mechanisms. It requires electricity suppliers to source a proportion of their electricity from renewable generators or purchase Renewable Obligation Certificates.
Suppliers that do not meet the required renewable targets must pay into a buy-out fund, which is then redistributed within the industry. The cost of complying with these requirements is included in the non-commodity charges of business electricity bills.
Feed-in Tariff (FiT)
The Feed-in-Tariff scheme was introduced to encourage small-scale renewable energy generation, such as solar panels and micro wind systems. Under this programme, eligible generators received payments for the electricity they produced and exported to the grid.
Although the scheme closed to new applicants in 2019, existing participants continue to receive payments under their agreements. The funding for these payments is collected from electricity suppliers and incorporated into energy bills.
Climate Change Levy (CCL)
The Climate Change Levy is a government tax on business energy usage in the UK. Its primary objective is to encourage organisations to improve energy efficiency and reduce emissions.
The levy applies to electricity, gas and certain other fuels used by businesses and public sector organisations. However, some organisations that participate in energy efficiency agreements may qualify for partial relief.
Network and grid charges (DUoS, TNUoS, BSUoS)
A major part of non-commodity costs is made up of electricity network charges that cover the cost of operating and maintaining the electricity infrastructure.
- Distribution Use of System (DUoS) charges relate to the regional distribution networks that transport electricity from the transmission system to businesses.
- Transmission Network Use of System (TNUoS) charges support the network that moves electricity from power stations to regional distribution networks across the country.
- Balancing Services Use of System (BSUoS) charges fund the work that balances electricity supply and demand, ensuring that the grid remains stable and reliable as generation fluctuates.
These can represent a significant share of a business electricity bill and they may vary based on location, connection type and how you use electricity.
What is the difference between commodity and non-commodity costs?
Commodity and non-commodity costs represent two distinct components of a business energy bill. Understanding the difference helps organisations identify what portion of their bill relates directly to each side.
| Feature | Non-commodity costs | Commodity costs |
| Definition | Charges that fund infrastructure, policy programmes and network requirements | Cost of purchasing electricity or gas on wholesale markets |
| Purpose | Supports grid operation, renewable initiatives and government policy | Pays for the actual energy supplied |
| Price Drivers | Government policy, regulatory changes
and infrastructure investment |
Global energy markets, fuel costs, supply and demand |
| Stability | Can change due to policy updates or regulatory reforms | Often fluctuates based on market conditions |
| Control | Typically regulated or mandated through industry frameworks | Influenced by market trading and supplier procurement |
Both components are essential for delivering reliable energy to businesses, but they respond to very different economic and regulatory influences.
Why are non-commodity costs increasing?
Non-commodity costs in the UK energy sector have been rising in recent years due to a combination of policy, infrastructure and market-related factors. One of the primary drivers is the increasing investment required to support the transition toward low-carbon energy generation.
The expansion of renewable energy sources such as offshore and onshore wind, along with solar power, requires significant upgrades to the national electricity network. Transmission lines, substations and grid balancing technologies must be enhanced to accommodate the changing generation landscape.
Another factor influencing these costs is the modernisation of the UK electricity grid. As demand patterns evolve and electrification increases across sectors, the grid must become more flexible and resilient. Regional infrastructure differences can also affect how these charges are distributed, meaning businesses in different parts of the UK may experience variations in costs.
Overall, the combination of environmental policy, infrastructure development and system reliability requirements continues to place pressure on non-commodity charges.
What changes to expect in non-commodity costs in 2026?
Looking ahead to 2026, businesses may experience further adjustments to non-commodity costs as regulatory reforms and network developments continue to evolve.
The UK energy system is undergoing a significant transformation as the country works towards long term decarbonisation targets. As part of this transition, several elements of the non commodity cost structure are expected to be reviewed or updated.
Changes may affect transmission charging methodologies, environmental levy structures and how network costs are allocated.
Expected transmission cost adjustments
Transmission charging structures are periodically reviewed to ensure that the costs of maintaining and expanding the national grid are distributed fairly. In 2026, further adjustments may occur as grid infrastructure continues to expand.
These changes could alter how transmission costs are calculated for businesses connected to different parts of the network. Organisations operating in areas undergoing significant infrastructure development may notice shifts in how charges appear.
Policy and environmental levy updates
Environmental policy remains a central element of the UK energy strategy. As renewable energy generation continues to grow, the mechanisms used to fund environmental programmes may be reviewed or adjusted.
Businesses should monitor regulatory announcements closely, as policy changes can directly influence non-commodity cost structures.
Network charging reforms
Network charging reforms aim to improve transparency and fairness in how electricity network costs are recovered. Industry bodies periodically review charging methodologies to ensure costs reflect how businesses use the grid.
These reforms can influence how distribution and balancing charges are calculated. For some organisations, this may result in changes to the timing or structure of certain charges.
How can businesses reduce non-commodity costs?
Although many non-commodity charges are regulated and unavoidable, businesses can still take practical steps to manage their overall exposure to these costs.
- Improving energy efficiency. By reducing overall electricity consumption, businesses can lower the total amount of energy subject to non-commodity levies and network charges.
- Reviewing energy usage patterns. Certain network charges are influenced by how much electricity is consumed at different times. Businesses that adjust operations to avoid peak demand periods may be able to reduce costs.
- Participation in energy management initiatives. This helps businesses demonstrate commitment to sustainability and improve operational energy performance.
- Staying informed about regulatory changes. Being knowledgeable allows businesses to anticipate cost adjustments and plan accordingly.
The UK energy landscape continues to evolve, and organisations that actively monitor industry developments are often better positioned to manage long-term energy costs.
Conclusion
Non-commodity costs play a critical role in the structure of UK business energy bills. While they do not represent the cost of generating electricity or gas, they fund the infrastructure, environmental programmes and policy mechanisms that support the national energy system.
As the energy sector continues to evolve, non-commodity costs are likely to remain a key component of business electricity bills. Infrastructure investment, regulatory updates and environmental policy developments will continue to shape how these charges are applied.
Looking ahead to 2026, continued grid investment and policy adjustments mean that non-commodity charges may continue to evolve.
