Unit Rates, Standing Charges & What's Next
By Christian Arnott, Direct Global
Understanding what drives energy costs is one of the most effective ways for businesses to take control of their expenditure. While unit rates and standing charges appear as simple line items on an invoice, the mechanics behind them are far more complex, and increasingly important as the UK moves towards a lower carbon future.
In this article, Christian Arnott breaks down the true makeup of an energy bill, explores why certain charges are set to rise, and explains why now is the time for businesses to review their procurement strategies.
What Really Makes Up the Price You Pay?
A business’s energy bill is split into two main components, each contributing very differently to the final cost.
Commodity Costs: The Wholesale Element
Commodity costs account for roughly 40 percent of the typical bill. This represents the price of the physical energy delivered to a site. While wholesale markets are relatively stable at present, they remain sensitive to global pressures.
Events such as colder winters or geopolitical tensions can quickly influence supply and demand, pushing prices up.
Non-Commodity Costs: The Hidden Majority
The remaining 60 percent of an energy bill is made up of non-commodity charges. These include government taxes, system levies and infrastructure-related costs designed to build, maintain and modernise the UK’s energy system.
These charges fund essential national upgrades, support renewable development and ensure network reliability, but they also represent the part of the bill that is expected to rise most sharply in the coming years.
The Real Pressure Point for Businesses
While wholesale prices draw the most attention, non-commodity costs are where the long-term upward pressure sits. Between now and 2030, significant increases are expected as part of the UK’s transition towards Net Zero.
Several major suppliers estimate that business energy bills could rise by around 20 percent in the next four to five years, even if wholesale prices remain exactly where they are today. Some have gone further, suggesting that even if wholesale energy were free, non-commodity charges alone would still result in similar overall costs to what businesses are currently paying.
This shift means organisations can no longer rely solely on market timing or commodity-focused strategies. The structural changes happening within the energy system will affect every business, regardless of their consumption profile.
Why Now Is the Time to Review Procurement Strategy
With these cost pressures on the horizon, proactive planning is essential. At Direct Global, we work with organisations to build procurement strategies that reflect both current needs and future cost landscapes.
A well-designed procurement plan can:
- Provide visibility of potential cost increases up to three years in advance
- Match contract types to a business’s risk appetite
- Secure agreements before non-commodity rises come into effect
- Offer greater stability against long-term uncertainty
Importantly, reviewing procurement does not only protect against future increases, it can also create savings immediately.
Unlocking Immediate Opportunities
Even businesses already locked into long-duration contracts may be able to reduce costs now. By reviewing current agreements, analysing standing charges and identifying inefficiencies, it is often possible to make tangible reductions without waiting for a contract to expire.
For organisations with agreements running into 2027 and beyond, these early interventions can make a meaningful difference to annual budgets.
Looking Ahead: Building Cost Certainty in an Evolving Market
The UK’s energy landscape is changing rapidly. Wholesale markets may fluctuate, but non-commodity charges are almost certain to rise as the country continues its investment in Net Zero infrastructure.
Businesses that understand how their costs are constructed and act early to adapt their procurement strategy, will be better positioned to manage these increases and protect their margins.
With the right insight and guidance, organisations can build an energy strategy that is resilient, predictable and aligned with the long-term direction of the UK energy market.
