Should UK Businesses Fix Their Energy Prices Now? April 2026 Market Update
The conversation around business energy pricing in 2026 is no longer just about wholesale gas or electricity rates. For most UK businesses, the real story is increasingly being driven by non-commodity costs - particularly network charging reforms such as TNUoS (Transmission Use of System) and DUoS (Distribution Use of System), alongside wider capacity and system balancing costs.
These charges are now reshaping how total energy costs behave - and in many cases, they are becoming more important than the wholesale price itself.
So the real question businesses should be asking is not simply “should I fix my energy now?” but:
“What proportion of my bill is actually still exposed to wholesale risk?”
The Market Has Shifted - Fixing Price Isn’t What It Used to Be
Historically, fixing energy prices was about locking in wholesale volatility.
In 2026, that logic is only part of the picture.
Even when wholesale markets stabilise, businesses are still seeing upward pressure from:
Transmission network upgrades
Local distribution reinforcement
Grid balancing and capacity mechanisms
Policy levies and environmental charges
These are increasingly embedded in standing charges and unit rates - meaning bills can rise even in a “flat” wholesale market.
The Real Driver Now: Network and System Costs
TNUoS - Transmission Charges
TNUoS funds the high-voltage transmission system that moves electricity across the UK.
What’s important for businesses is not just the existence of the charge, but how it is being recovered.
Recent reforms have pushed more cost recovery into fixed or capacity-based elements, meaning:
Costs are less linked to consumption
Standing charges are increasing in importance
Location and network zone matter more than ever
In practice, two identical businesses in different regions can now see materially different cost outcomes.
DUoS - Local Distribution Charges
DUoS covers the local network (the “last mile” of electricity delivery).
This is where businesses are increasingly exposed to:
Time-of-use charging (peak vs off-peak pressure)
Regional pricing differences
Higher fixed components within bills
Even for businesses that do not actively manage load shifting, DUoS is quietly becoming a material cost driver in its own right.
Why This Matters for Contract Strategy
This shift changes how energy procurement should be viewed.
Traditionally:
“Fix = hedge wholesale risk”
Now:
“Fix = lock in a blended bundle of wholesale + network + system costs”
That matters because:
Some suppliers absorb risk differently in bundled pricing
Standing charge structures vary significantly between contracts
Capacity assumptions (kVA) can distort total cost more than unit rate
Contract timing still matters, but not for the same reasons as before
So Should Businesses Fix Now?
There is no universal answer - but the decision is no longer binary.
Instead, businesses should think in three layers:
1. Wholesale exposure
Still relevant, but no longer the dominant driver of volatility.
2. Network exposure (TNUoS / DUoS)
Increasingly structural, less avoidable, and more region-dependent.
3. Site infrastructure exposure
Often overlooked - but critical:
agreed capacity (kVA)
half-hourly profiling
maximum demand
inefficiencies in load behaviour
Why Many Businesses Are Misreading the Market
A common misconception is that falling wholesale prices automatically mean lower bills.
In reality, we are seeing:
Wholesale softening in some forward curves
But rising non-commodity and capacity charges
Increased standing charge weighting in tariffs
Greater disparity between “cheap unit rate” and “total cost outcome”
This is why simple price comparisons are becoming less reliable.
Beyond Brokerage: Why Infrastructure Now Matters
This is where energy strategy becomes more technical.
A procurement-only approach is no longer enough on its own.
We increasingly support businesses by looking at:
HV / LV infrastructure constraints
kVA tolerance and capacity optimisation
Half-hourly data profiling
Demand peaks and inefficiency mapping
Contract structure vs actual site behaviour
Portfolio-wide cost allocation across multiple sites
Because in many cases, the biggest savings are no longer in switching supplier - they are in fixing the structure of how energy is being used and billed.
Final View: Fixing Is Still Relevant - But Not the Whole Strategy
Fixing energy prices is still a valid risk-management tool.
But in 2026, it should be treated as just one part of a wider strategy that also considers:
network charges
capacity settings
infrastructure constraints
consumption behaviour
Businesses that treat energy as a procurement exercise only will increasingly miss the bigger cost drivers.
Need a Proper Energy Position Review?
If your business is approaching renewal, the most valuable step is not just comparing prices - it’s understanding:
what you are actually exposed to
where your costs are really coming from
and whether your infrastructure is aligned with your contract structure
We provide independent energy reviews that go beyond brokerage - combining procurement, infrastructure analysis, and cost optimisation to build a clearer picture of total energy performance.
