How the Iran Conflict Is Affecting UK Business Energy Prices in March 2026
Geopolitical tensions in the Middle East have once again moved global energy markets – and UK businesses are starting to feel the impact.
Following escalating conflict involving Iran and regional powers, wholesale oil and gas markets have reacted sharply. While the UK doesn’t buy energy directly from Iran, global energy is traded in interconnected markets. When supply routes are threatened, prices rise everywhere.
In this guide, we explain:
- Why energy markets are reacting
- How it affects UK business electricity and gas prices
- What business owners should do next
What’s Happening in the Middle East?
Recent developments have centred around rising tensions involving Iran and activity in the Strait of Hormuz – one of the world’s most important energy shipping routes.
Around 20% of the world’s oil and a significant volume of liquefied natural gas (LNG) passes through this narrow corridor daily. Any disruption – or even the risk of disruption – immediately impacts global markets.
Energy traders don’t wait for shortages to occur. They price in risk. And that risk premium feeds directly into wholesale oil and gas contracts.
Why Energy Prices React So Quickly
Energy markets are forward-looking. That means prices move based on expectations of future supply and demand – not just current flows.
Here’s what’s driving volatility right now:
1. Oil Prices Have Jumped
Brent crude has risen sharply in response to fears of supply disruption. Even if physical flows continue, uncertainty alone pushes prices higher.
Higher oil prices increase:
- Transport costs
- Manufacturing costs
- Distribution costs
- Inflationary pressure across the economy
2. Gas Prices Are More Important for the UK
For UK businesses, natural gas is the bigger issue.
The UK relies heavily on gas for electricity generation. When wholesale gas prices rise, electricity wholesale prices follow.
European gas benchmarks have moved higher in recent weeks as markets assess potential LNG disruption and global supply tightness.
That feeds directly into UK forward contracts for business energy.
How This Affects UK Business Energy Prices
Short-Term Impact
If your business energy contract is:
- Ending soon
- Already expired
- On out-of-contract rates
You are more exposed to recent wholesale increases.
Suppliers price contracts based on forward wholesale markets. If those markets rise, new fixed contracts rise too.
We are currently seeing:
- Increased volatility in 12-month contracts
- Shorter quote validity periods
- Greater intra-day price movement
Medium-Term Risk
If tensions persist:
- Winter 2026 contracts could price higher
- Electricity forward curves may continue rising
- Market volatility could remain elevated
However, if tensions ease and supply routes stabilise, markets can retrace quickly – as we’ve seen during previous geopolitical flare-ups.
Is This Another 2022 Energy Crisis?
Not at this stage.
There are key differences:
- Europe is less dependent on Russian gas than in 2022
- LNG import capacity has expanded
- Storage levels are more diversified
However, markets are still sensitive. Energy pricing remains structurally higher than historic pre-2020 levels, meaning geopolitical risk has a faster and stronger impact than it once did.
The key takeaway: this is volatility – not necessarily a structural collapse in supply.
What Should UK Businesses Do Now?
1. Check Your Contract End Date
If your contract ends within the next 3–6 months, now is the time to start reviewing options.
Leaving it too late in a volatile market can mean fewer pricing opportunities.
2. Avoid Out-of-Contract Rates
Deemed and out-of-contract rates are typically far higher and move more quickly when wholesale prices rise.
If your contract has expired, reviewing immediately is essential.
3. Don’t Panic-Fix Without Comparison
Markets often spike on headlines and then partially retrace.
The right approach isn’t panic — it’s structured review:
- Compare multiple suppliers
- Consider different contract lengths
- Assess risk tolerance
4. Monitor Forward Market Movement
Energy markets move daily. Timing matters.
A proactive strategy – rather than reactive renewal – can make a meaningful difference to overall contract cost.
The Bigger Picture: Why Geopolitics Matters to UK SMEs
Many business owners assume global conflict won’t affect them directly.
But energy is globally traded. A shipping disruption in the Middle East can influence:
- Gas used to generate UK electricity
- Diesel used in logistics
- Manufacturing input costs
- Food production and hospitality overheads
For energy-intensive sectors such as hospitality, manufacturing, leisure and retail, wholesale shifts quickly filter into operating costs.
What This Means for Your Business Energy Contract
Your exposure to current market volatility largely depends on when your contract expires.
If your contract expires in the next 1–3 months
Supplier pricing doesn’t adjust instantly — there is usually a short lag behind wholesale market movements. That means quotes available today may not yet fully reflect the most recent spikes.
If you’ve been delaying your renewal review, now is the time to start the process. Not out of panic – but because the window before suppliers reprice more significantly could be short.
Early comparison gives you leverage and options. Securing quotes now allows you to benchmark the market before further volatility feeds through.

If your contract runs until later in 2026
You have more breathing space, but it’s still wise to monitor developments closely.
If disruption in the Strait of Hormuz continues for weeks rather than days, forward contracts for later in the year are likely to rise as markets price in sustained risk.
Planning ahead — rather than waiting until the final few months — reduces exposure to sudden price movements. Even obtaining a benchmark quote now can help you understand where the market stands and plan accordingly.

If you have 12 months or more remaining on your contract
Your rates are protected until your agreed end date. Short-term wholesale fluctuations won’t affect what you’re currently paying.
There’s no immediate action required, but keeping an eye on market direction as you approach renewal will help you time your next move more strategically.
If you’re on out-of-contract or deemed rates
This is the most exposed position to be in.
Out-of-contract rates are typically higher than fixed agreements and tend to increase more quickly when wholesale markets rise.
Securing a competitive fixed contract should be a priority to reduce unnecessary cost exposure and regain pricing certainty.

Frequently Asked Questions
Will the Iran crisis permanently increase UK business energy bills?
Not necessarily. Markets are pricing in risk. If tensions ease, some of the recent increases could unwind. If conflict escalates or supply routes are disrupted for a prolonged period, prices could remain elevated.
Should I fix my business energy prices now?
That depends on:
- Your current contract expiry
- Your appetite for risk
- Market conditions at the time of renewal
Early comparison gives you more control.
Why does gas affect electricity prices?
Gas-fired power stations still set the marginal price of electricity in the UK. When wholesale gas rises, electricity prices typically follow.
Final Thoughts: Volatility Creates Risk — But Also Opportunity
Geopolitical events like the Iran crisis can move energy markets quickly. But volatility doesn’t automatically mean higher costs for every business.
The key difference between overpaying and securing a competitive contract often comes down to timing, preparation and market awareness.
If your renewal window is approaching, reviewing options early gives you control. If your contract runs later into 2026, benchmarking the market now provides clarity — even if you decide to wait before committing.
Energy markets reward proactive businesses.
