What is a fixed energy deal?

A fixed energy deal, also known as a fixed tariff, locks in the unit rates and standing charges you pay for your gas and electricity for a set period. This means the price per kilowatt-hour (kWh) of energy you use and your daily standing charge remain constant, regardless of changes in the wholesale energy market. These contracts typically last between 12 and 18 months, offering a degree of certainty over your energy expenditure.

Understanding fixed tariffs

Unlike a variable tariff, where unit rates and standing charges can change quarterly in line with the Ofgem energy price cap, a fixed tariff provides stability. For instance, the Ofgem Price Cap for a typical Direct Debit household on a default tariff from 1 July to 30 September 2026 is 26.11p per kWh for electricity. If you are on a fixed deal, your rates would not change even if the price cap increases during your contract term.

How fixed rates work

While fixed deals lock in your unit rates and standing charges, they do not fix your total energy bill. Your overall bill will still vary depending on how much energy you use. The more energy you consume, the higher your bill will be, even with fixed rates.

Does a fixed tariff mean my monthly bill stays the same?

No, a fixed tariff guarantees the unit rate (kWh) and the standing charge for a set period, not your total monthly bill. Your bill will still fluctuate based on your actual energy consumption, meaning if you use more energy, you will pay more overall.

To put this into perspective, the average UK home uses around 2,500 kWh of electricity per year and 9,500 kWh of gas per year. Understanding your household's typical consumption helps you estimate your potential bills, even with fixed unit rates. For instance, exploring options like an air source heat pump can help you manage your energy usage more efficiently.

Benefits of a fixed energy deal

Choosing a fixed energy deal can bring several advantages, particularly for those who value stability and predictability in their household finances.

Budget certainty and predictability

The primary benefit of a fixed energy deal is the certainty it provides for your budget. Knowing that your unit rates and standing charges will not change for the duration of your contract allows you to plan your household spending with greater confidence. This predictability can free up mental space, reducing the anxiety often associated with fluctuating energy costs.

Protection against price rises

Fixed energy deals act as a shield against sudden increases in wholesale energy prices. If market prices for gas and electricity rise, your fixed rates remain unchanged, protecting you from higher costs that those on variable tariffs might face. This can be particularly valuable during periods of market volatility.

Peace of mind

Beyond financial protection, fixed deals offer peace of mind. You won't need to constantly monitor market fluctuations or worry about unexpected bill increases. Fuse Energy enhances this peace of mind with 24/7 human customer support, ensuring you have assistance whenever questions arise about your fixed deal terms or market changes. This commitment to transparency and control aligns with the desire for clear, predictable digital products.

Potential downsides to consider

While fixed energy deals offer significant advantages, it's important to be aware of potential drawbacks before committing to a contract.

Market price fluctuations

One potential downside is that if wholesale energy prices fall significantly during your fixed term, you might end up paying more than those on variable tariffs. Your fixed unit rates will not decrease automatically, meaning you could miss out on potential savings if the market shifts in consumers' favour.

Exit fees and flexibility

Most fixed energy deals come with exit fees, which you will need to pay if you decide to switch providers or tariffs before your contract ends. These fees are tariff-specific and can vary, with an illustrative figure of £50 often used per fuel, per meter. This can limit your flexibility, making it costly to switch even if a more attractive deal becomes available elsewhere. However, you typically won't pay an exit fee if you switch within the last 49 days of your contract.

Usage still affects total bill

It's crucial to remember that a fixed deal only locks in the unit rates and standing charges, not your total bill. Your monthly payment will still fluctuate based on your energy consumption. If your household uses more energy than anticipated, your total bill will increase accordingly, even with fixed rates.

How to choose the right fixed deal

Selecting the right fixed energy deal requires careful consideration of various factors to ensure it aligns with your household's needs and financial goals.

Comparing offers and suppliers

Start by comparing fixed deals from different suppliers. Look beyond just the headline price and examine the unit rates for electricity and gas, as well as the daily standing charges. Comparison websites can be useful tools for this, but always verify the details directly with the supplier.

Assessing contract length and terms

Fixed deals typically last between 12 and 18 months. Consider how long you want to commit to a particular rate. Longer contracts offer extended price stability but might mean you're locked in for longer if market prices fall. Always check the terms and conditions, especially regarding exit fees and what happens at the end of the contract.

Considering customer support and service

The quality of customer service can significantly impact your experience. A reliable supplier with accessible support can be invaluable, especially if you have questions about your bill or contract terms. Fuse Energy's 24/7 human customer support offers peace of mind, ensuring you can get assistance whenever you need it.

Is a fixed energy deal right for you?

Deciding whether a fixed energy deal is the right choice depends on your individual circumstances and priorities.

Evaluating your household needs

Consider your household's energy consumption patterns and budgeting preferences. If you value predictable monthly outgoings and want to shield yourself from potential price hikes, a fixed deal might be suitable. Additionally, understanding the benefits of efficient air conditioning installation can further help in managing your overall energy consumption. However, if you prefer the flexibility to switch without fees and are comfortable with your rates fluctuating with the market, a variable tariff could be a better fit.

When to opt for a fixed tariff

A fixed tariff is often a good option if you:

  • Prioritise budget certainty and predictability.
  • Want protection against potential energy price increases.
  • Prefer not to constantly monitor energy market changes.

Making an informed decision

Ultimately, making an informed decision involves weighing the benefits of price stability against the potential for missing out on future price drops and the impact of exit fees. Ofgem, the energy regulator, oversees the energy market in Great Britain and ensures suppliers clearly communicate the terms and conditions of fixed energy deals, including contract length and any exit fees. By understanding these factors and comparing available options, you can choose an energy deal that best suits your financial goals and provides peace of mind.
