Fixed vs Variable Business Energy Tariffs: Which is Right for Your Company?
Choosing the right energy tariff is one of the most important financial decisions a business can make. With energy prices in the UK still fluctuating and the pressure on companies to cut costs higher than ever, deciding between a fixed tariff and a variable tariff can have a significant impact on your bottom line.
On the surface, the choice might seem simple: fix your prices for certainty, or go variable to chase potential savings. But in reality, the decision is far more complex. The correct tariff depends on your company’s size, energy usage patterns, risk appetite, and long-term goals. In this blog, we will explore the differences between fixed and variable business energy tariffs, the benefits and drawbacks of each, and how a broker like One Helix can help you make the right choice for your business.
What Are Fixed Business Energy Tariffs?
A fixed business energy tariff means your unit price for gas and electricity remains the same for the entire length of your contract, which typically ranges from 1 to 5 years. Importantly, this does not mean your bill will always remain the same, as the total cost still depends on the amount of energy you use. However, the stability of a fixed rate provides certainty over what you pay per kilowatt-hour.
Fixed tariffs are popular because they offer predictability. When you know your rates will not change regardless of market conditions, you can plan your budgets with confidence. For many businesses, this level of financial stability is worth paying a slight premium for.
What Are Variable Business Energy Tariffs?
Variable business energy tariffs, sometimes referred to as “flexible tariffs,” track the movements of the wholesale energy market. When prices fall, your business benefits from lower bills, but when prices rise, you will see your costs increase.
Variable tariffs can feel risky, especially during periods of volatility, but they also provide the chance to capitalise on falling market rates. For businesses willing to take on more uncertainty, a variable tariff can deliver savings compared to locking into a fixed contract at the wrong time.
Benefits of Fixed Tariffs
Stability and Predictability
The main advantage of a fixed tariff is certainty. You know precisely what you will pay per unit of energy, making it easier to manage cash flow and set financial forecasts.
Protection Against Market Spikes
With the UK energy market often influenced by global events, a fixed tariff provides protection for your business against sudden price surges. This peace of mind is particularly valuable during unstable periods.
Easier Budgeting
For businesses with tight margins, the ability to forecast energy costs without worrying about fluctuations can be a significant advantage.
Drawbacks of Fixed Tariffs
Potentially Higher Costs: When you fix your rates, you could miss out on savings if wholesale prices drop during your contract.
Less Flexibility: Breaking a fixed contract early typically incurs penalties. This can make it harder for businesses to adapt if their energy needs change.
Benefits of Variable Tariffs
Opportunity to Save Money: If market prices fall, your business will benefit immediately. Over time, this can result in significant savings compared to a fixed rate.
Greater Flexibility: Variable tariffs are often more flexible, with shorter contract terms or fewer penalties for switching. This can be useful for businesses expecting changes in energy usage or growth.
Drawbacks of Variable Tariffs
Exposure to Volatility: Variable tariffs leave your business vulnerable to sudden price hikes, making budgeting unpredictable and risky.
Higher Risk for SMEs: For smaller businesses with less financial cushioning, the unpredictability of variable tariffs can be a significant concern.
Which Tariff Is Right for Your Business?
The decision between fixed and variable tariffs ultimately comes down to your company’s priorities. If financial stability and predictability are critical, a fixed tariff may be the best choice. If your business can absorb some risk and wants to capitalise on potential market dips, a variable tariff may be more effective.
Large businesses with higher consumption may find value in variable contracts if they have the resources to manage fluctuations, while SMEs often prefer the security of fixed rates. It is also worth considering hybrid strategies — for example, fixing part of your energy usage while leaving some on a variable rate.
