Business Energy Prices Winter 2026: What Businesses Should Know Before Renewing Their Energy Contract
Many business owners hoped that energy market volatility would fade after the challenges of recent years. While conditions have improved significantly since the peak of the energy crisis, energy prices remain heavily influenced by global events, wholesale gas costs and winter demand.
For organisations approaching an energy contract renewal, the key question is no longer simply "Will prices go up or down?" Instead, it's "How can we prepare for uncertainty and make informed decisions?"
Winter 2026 at a Glance
What we’re paying close attention to:
Wholesale gas price movements.
LNG (Liquefied Natural Gas) availability across Europe.
Winter weather forecasts and heating demand.
Energy contract renewal timelines.
Opportunities to improve long-term energy resilience.
Tewdric Energy's view: Businesses that begin reviewing their energy arrangements 6-12 months before renewal are often in a stronger position than those who wait until the last minute.
Why Are Business Energy Prices Still Unpredictable in 2026?
Although renewable energy generation continues to increase, the UK still relies on natural gas for a significant proportion of electricity generation. This means that wholesale gas prices remain one of the biggest drivers of business energy costs.
Energy markets are also affected by:
International supply and demand.
Competition for LNG cargoes.
Weather conditions across Europe (not just the extreme ones like heatwaves, floods, etc)
Geopolitical developments affecting energy supply chains (anything where politicians are involved it seems)
Global economic activity - let’s be honest, it’s always about supply and demand.
As a result, market conditions can change quickly, particularly during the winter months when energy demand is highest.
What Should Businesses Watch This Winter?
1. Wholesale Gas Prices
Gas continues to play a major role in determining electricity prices across the UK.
If wholesale gas prices rise, businesses approaching contract renewals may see this reflected in energy supplier quotations.
This doesn't mean prices will necessarily increase dramatically, but it does mean organisations should monitor market conditions rather than assume stability.
2. Winter Weather
Cold weather increases demand for heating across the UK and Europe.
Higher demand can place pressure on gas supplies and wholesale markets, particularly during prolonged periods of low temperatures.
A milder winter may help ease some of that pressure, but weather remains one of the biggest unknowns in the energy market.
3. Global LNG Supply
Liquefied Natural Gas has become increasingly important to Europe's energy security.
Europe now competes with other regions, particularly Asia, for LNG shipments.
When global demand increases, competition for available supply can influence wholesale energy prices across the UK.
4. Global Events
Energy markets are interconnected.
Events affecting oil and gas production, international shipping routes or major energy-producing regions can quickly influence pricing and market confidence.
This is why businesses often see market movements linked to events occurring well beyond the UK.
When Should Businesses Start Planning Their Energy Contract Renewal?
One of the most common mistakes organisations make is waiting until a contract is close to expiry before exploring their options - and why energy brokers benefit from it most.
Ideally, businesses should begin reviewing their position six to twelve months before renewal.
This provides time to:
Review energy consumption patterns
Understand current market conditions
Explore opportunities to reduce future costs
Make informed decisions without unnecessary pressure that align with their business needs
A proactive approach often provides greater flexibility than leaving decisions until the final few weeks of a contract.
How Can Businesses Reduce Exposure to Energy Market Volatility?
Unfortunatley no business can control wholesale markets, but every organisation can take steps to improve their own resilience to what it can predict - in the same way it does when it plans for other business costs.
Review Energy Usage
Understanding how and when energy is consumed is often the first step towards reducing costs.
Many businesses identify opportunities for efficiency improvements simply by reviewing usage patterns more closely.
Improve Energy Efficiency
Simple operational changes can reduce waste and improve overall energy performance.

Consider Renewable Energy Technologies
An increasing number of organisations are investing in:
Solar PV systems
Battery storage
Smart energy management technologies
EV charging infrastructure
These technologies can help organisations reduce dependence on grid electricity and gain greater control over future energy costs.

Businesses that understand their options early are often better placed to assess risk, manage budgets and make decisions that support long-term objectives.
What Tewdric Energy Is Seeing in the Market
Many of the businesses we speak to are no longer focused solely on finding the lowest possible unit rate.
Instead, they are increasingly asking:
How can we improve budget certainty?
How can we reduce exposure to future market shocks?
Does solar or battery storage make sense for us?
How can we become more energy resilient?
This represents an important shift in thinking.
Rather than trying to predict every market movement, organisations are focusing on strategies that provide greater control over their energy future. You may also find our case study from Jaga Brothers an interesting read.
Frequently Asked Questions
Will business energy prices rise this winter?
Wholesale gas prices, LNG availability, weather conditions and global events will continue to influence market movements throughout winter 2026. While one can predict future prices with certainty the current volatility and upward trend would indicate that we will see some increase over winter 2026.
When should I review my business energy contract?
Ideally six to twelve months before the renewal date. This gives businesses time to understand market conditions and evaluate their options. However, we urge all businesses to check their contracts if they have used a broker to ensure you aren’t tied in to renewals even 12 months out!
What affects business energy prices the most?
Wholesale gas prices remain one of the biggest drivers of UK business energy costs, alongside supply and demand, weather patterns and geopolitical developments.
Can businesses protect themselves from energy market volatility?
While businesses cannot eliminate market risk entirely, they can reduce exposure through energy efficiency measures, strategic procurement, solar PV, battery storage and better energy management.
Is now a good time to look at solar and battery storage?
Yes! Many organisations are exploring solar and battery technologies as a way to gain greater control over future energy costs and improve long-term resilience.
The Bottom Line
The UK's energy market is in a stronger position than it was during the energy crisis, but uncertainty has not disappeared.
For businesses approaching an energy contract renewal, preparation remains one of the most effective ways to manage risk. Understanding market conditions, reviewing energy use and exploring long-term energy strategies can help organisations make confident, informed decisions.
At Tewdric Energy, we help businesses navigate energy markets, understand their options and build practical strategies for managing future energy costs.
