The UK energy market offers two main types of tariffs: fixed and variable. Each has a distinct pricing structure and responds differently to market changes.
What is a fixed energy tariff?
A fixed energy tariff locks in the unit rate you pay for each kilowatt-hour (kWh) of gas and electricity, along with your daily standing charge, for a set period. This typically lasts between 12 and 18 months. During this contract, your supplier cannot change these rates, offering price certainty regardless of market fluctuations. While the unit rates are fixed, your total bill will still depend on your energy usage.
What is a variable energy tariff?
With a variable energy tariff, the unit rates and standing charges you pay can change. These tariffs are subject to the Ofgem Energy Price Cap, which updates quarterly. This means your energy costs can go up or down based on market conditions, offering flexibility but less predictability. You can learn more about standard variable tariffs and how they compare to fixed options.
The energy price cap explained
The Ofgem Energy Price Cap sets a maximum amount energy suppliers can charge per unit of energy and for the daily standing charge on variable tariffs. It is updated quarterly, influencing how much households on variable rates pay for their gas and electricity. This cap ensures that variable tariffs remain fair, even when wholesale energy prices are high.
Benefits of a fixed tariff
The main advantage of a fixed tariff is price certainty. Knowing your unit rates will not change for 12 to 18 months allows for easier budgeting and protects you from sudden price increases in the wholesale energy market. This can provide peace of mind, especially during periods of market volatility.
Potential drawbacks of fixing your price
While fixed tariffs offer stability, they can also come with downsides. If wholesale energy prices fall significantly, you might be locked into a higher rate than those on variable tariffs. Additionally, fixed tariffs often include exit fees if you decide to switch suppliers before your contract ends.
Understanding exit fees
Exit fees are charges applied if you leave a fixed tariff before its contract term is complete. These fees can be around £50 per fuel (gas and electricity). As Fuse Energy does not offer dual-fuel tariffs, customers would have separate electricity and gas tariffs, each potentially incurring an exit fee. However, exit fees are not applied if your contract ends within 49 days, allowing you to move to a new deal without penalty near the end of your term.
Benefits of a variable tariff
Variable tariffs offer flexibility. If wholesale energy prices drop, your rates will typically follow suit, potentially leading to lower bills. They also usually come without exit fees, giving you the freedom to switch to a different tariff or supplier at any time without penalty. Understanding different energy tariffs can help you make an informed choice.
Potential drawbacks of variable rates
The primary drawback of a variable tariff is the uncertainty. Your unit rates and standing charges can change quarterly, making budgeting more challenging. If wholesale energy prices rise, your bills will increase, even if your usage remains the same.
How the price cap influences variable tariffs
The Ofgem Energy Price Cap directly regulates the maximum rates for variable energy tariffs in the UK. This cap is reviewed and updated every three months, meaning your variable tariff rates can change four times a year. It acts as a safety net, preventing suppliers from charging excessively high prices, but it does not prevent rates from increasing up to the cap limit.
Deciding between a fixed and variable tariff depends on your personal circumstances and risk tolerance.
Your household's energy usage
Understanding your household's energy consumption patterns is crucial. The average UK home uses around 2,500 kilowatt-hours (kWh) of electricity and 9,500 kWh of gas per year, which are Ofgem's medium typical domestic consumption values effective from 1 July 2026. If your usage is significantly higher or lower, this might influence which tariff type offers better value. For example, if you have high, consistent usage, a fixed tariff could offer more predictable costs.
Your risk tolerance
Consider how comfortable you are with fluctuating bills. If you prefer stability and predictable monthly payments, a fixed tariff might be more suitable. If you are willing to take a chance on market drops for potentially lower bills, and can absorb potential increases, a variable tariff could be an option.
Current market conditions and forecasts
Keep an eye on current energy market conditions and price cap forecasts. While no one can guarantee future prices, understanding trends can help you make a more informed decision. If prices are expected to rise, fixing your rate might be appealing. If they are predicted to fall, a variable tariff could be more attractive.
