Why Are Business Energy Prices So High? UK Energy Market Update – September 2026

Why are business energy prices so high?
UK business energy prices remain high and volatile as we approach winter 2026.

Although wholesale gas and electricity prices have moved slightly from their recent peaks, the market remains under significant pressure from geopolitical uncertainty, restricted global gas supplies and concerns over European gas storage.

For businesses looking to renew their gas or electricity contracts, understanding what is driving the market is important. Short-term energy prices are currently particularly expensive, while prices further along the forward curve are noticeably lower.

Here are some of the main reasons.

1. Middle East tensions are keeping energy markets nervous
One of the biggest drivers of current wholesale energy prices is the continuing conflict involving the US and Iran.

The market remains sensitive to developments in the Middle East because of the importance of the region to global oil and LNG supplies.

According to the latest market report, traffic through the Strait of Hormuz has fallen dramatically, from around 125 large commercial vessels per day to just 12 over a recent weekend.

Any further escalation could place additional pressure on global gas and oil supplies, which could quickly feed through into higher UK gas and electricity prices.

2. Global LNG supplies have been significantly reduced
The UK and Europe have become increasingly dependent on Liquefied Natural Gas (LNG).

The latest data suggests that approximately 18% of global LNG supply has been removed from the market as a result of the conflict and associated disruption.

European and UK LNG imports have fallen by 2.7% during the first eight months of the year compared with the same period last year. Qatari LNG imports have fallen particularly sharply, by around 61%.

This creates greater competition between Europe and other international markets for the LNG cargoes that remain available.

When demand for LNG increases, wholesale gas prices generally rise.

3. European gas storage is lower than normal
Another major concern is the amount of gas currently stored across Europe.

European gas stocks are sitting at around 69%, approximately 12 percentage points below last year's levels.

Storage is particularly important heading into winter because it provides protection against periods of cold weather or supply disruption.

The lower the storage level, the more exposed Europe becomes to changes in demand and global LNG availability.

The report estimates that Europe needs around 5.1 billion cubic metres of additional gas, equivalent to approximately 53 LNG cargoes, just to move storage from 70% to 73%.

This is one of the reasons winter gas prices remain elevated.

4. The UK is becoming more dependent on US LNG
With fewer flexible sources of LNG available, Europe and the UK are increasingly dependent on supplies from the United States.

US LNG supply to Europe has already increased, while other traditional supply sources have become more constrained.

This means UK and European gas prices can increasingly be affected by developments in the US gas market.

Any increase in US demand, production problems or disruption to LNG export facilities could therefore have a knock-on effect on UK business gas prices.

5. Gas prices directly affect electricity prices
Businesses sometimes ask why electricity prices increase when the problem appears to be with gas.

The reason is that gas-fired power stations remain an important part of UK electricity generation.

The latest generation mix shows gas accounting for around 24.5% of UK electricity generation, alongside wind, nuclear, solar, biomass and imports.

When gas becomes more expensive, the cost of producing electricity can therefore increase as well.

This is why geopolitical events affecting gas supplies can quickly influence both business gas and business electricity prices.

Are there any positive signs?
There are some.

The UK gas system recently opened oversupplied, while Norwegian gas production is expected to improve as maintenance finishes.

Wind generation forecasts have also improved in the short term, which can reduce the amount of gas required for electricity generation.

Oil prices have also moved back below $100 per barrel following recent falls.

However, these positive factors have not removed the wider risks facing the market.

Why are longer-term energy contracts currently cheaper?
One of the most interesting features of today's market is the difference between short-term and longer-term prices.

For example, the report shows Winter 2026 gas at around 184 p/therm, compared with Summer 2028 at around 107 p/therm on indicative pricing. Electricity shows a similar pattern, with Winter 2026 considerably more expensive than later contracts.

In simple terms, the market expects some of today's supply pressures to ease over time.

This means some businesses may find that a longer-term fixed energy contract offers a lower average price than a short 12-month agreement.

That does not automatically mean a longer contract will be right for every business. Contract length, consumption, risk appetite and future business plans should all be considered.

Should businesses fix their energy prices now?
There is no single answer that is right for every business.

However, businesses with contracts due for renewal should consider reviewing the market early rather than waiting until their existing contract is about to expire.

The current market remains highly sensitive to political developments, LNG supply and winter weather.

A further escalation in the Middle East or disruption to LNG supplies could cause wholesale gas and electricity prices to rise quickly.

Equally, an improvement in geopolitical conditions could allow prices to fall.

At Utility Helpline, we therefore look at both the current market and the wider forward curve when helping clients decide when and how to purchase their energy.

How Utility Helpline can help
Utility Helpline has been helping UK businesses manage their energy costs for 20 years.

Rather than simply providing one energy quote, we compare offers across our supplier panel and help businesses understand the differences between contract lengths, products and suppliers.

We also continue supporting clients throughout their contract with billing queries, supplier issues, meter problems and ongoing account management.

If your business energy contract is due for renewal, or you would simply like to understand what today's market means for your business, speak to the Utility Helpline team.

Reviewing your options early gives you more time to monitor the market and decide when the right opportunity to secure your energy may arise.
