Neither plan is always better. A fixed-rate energy plan can make the contract’s specified prices more predictable for its term, while a variable plan may pass market changes through to you—up or down. Rising oil prices alone do not show whether your electricity or gas rate will rise: the effect depends on your local market, supplier purchasing and hedging, and the pricing formula in your contract.
Should you choose a fixed or variable energy plan?
Choose based on the actual offer, your budget needs, and how much price movement you can tolerate—not on oil prices by themselves. A fixed offer can suit a household that values predictability for the charges it fixes. A variable offer may suit someone willing to accept changes in exchange for the possibility of benefiting when relevant market prices fall. Neither is guaranteed to be cheaper overall.

Suppliers may buy electricity on short-term markets, long-term contracts, or a mix. Hedging can reduce their exposure to sudden wholesale increases and help support more predictable consumer rates; fixed offers commonly reflect the cost of that protection. A fixed plan may therefore cost more than a current variable offer because stability has a price, and suppliers price in expectations about future conditions. The European Commission explains electricity contract choice and hedging.

Will your electricity bill go up if oil prices rise?
Not necessarily, and not in a predictable one-for-one relationship. Electricity can come from wind, solar, nuclear, hydropower, gas, or coal. Wholesale prices respond to supply and demand, weather, interconnection, and fuel costs; gas and coal can contribute to price volatility. Your supplier’s purchasing strategy and your plan’s pricing formula determine how those changes may reach you. The available official guidance does not establish a universal formula linking oil prices to retail electricity or gas tariffs. The Commission’s electricity-market overview describes the mix of influences.

Minute and hour data are retained in the cloud. 1 minute data is retained 7 days, 1 hour data is retained indefinitely. Export cloud data whenever you want in the app.
Your total bill is also more than the energy commodity price. It can include network costs, taxes and levies, policy costs, and other charges. The Commission estimates that electricity costs accounted for nearly 49% of EU retail electricity bills on average in 2024; that is an EU-wide average, not a household-specific breakdown or a current local tariff. In Great Britain, Ofgem’s price-cap methodology includes wholesale, network, policy, operating, and other cost allowances. Commission bill-cost guidance and Ofgem’s explanation of the price cap describe these components.
What “fixed,” “variable,” and “dynamic” mean
Fixed-rate plans
A fixed plan holds the price elements identified in the contract for a stated term. It does not necessarily freeze every part of your bill: check whether standing charges, taxes, network charges, discounts, or other components can change. Your consumption still affects the bill, and leaving early may trigger a fee or other conditions.

Variable-rate plans
A variable plan can change according to the supplier’s terms, a market index, or other specified conditions. Check what the rate tracks, how frequently it can change, and what notice you will receive. Variable does not automatically mean that the price follows oil or wholesale energy prices directly.

Some dynamic offers vary more frequently—hourly or every 15 minutes in some EU offers. They may reward customers who can shift electricity use into lower-priced periods, but the outcome depends on the tariff formula and your flexibility. Read the contract summary for the index, change frequency, and illustrative bills for different consumption patterns.

How to compare two energy offers
Compare offers using your actual or best available annual consumption. The European Commission advises checking the total cost against estimated annual use and reading the contract summary. A headline discount or unit rate alone may hide important fees or conditions. The Commission’s contract-signing guidance explains what to review.
- Estimate the annual total. Include unit rates, standing charges or fixed fees, applicable network charges and taxes, discounts, and one-off fees. Use the same consumption estimate for both offers.
- Identify what can change. Note which components are fixed and whether the alternative is variable, indexed, dynamic, or mixed. For a changing rate, find the index or formula, change frequency, notice period, and where to monitor it.
- Read the contract conditions. Compare term length, renewal, cancellation, early-exit fees, applicable cooling-off rights, and whether discounts are temporary or conditional.
- Match the plan to your household. Consider how much predictable pricing matters to your budget, your tolerance for price swings, and—if considering a dynamic electricity plan—whether you can shift usage to cheaper hours and have access to a suitable tariff or meter.
- Check local protections and comparison services. Use your national or regional regulator and an official comparison tool where available. Price caps and consumer protections depend on jurisdiction.
For example, Great Britain’s Ofgem price cap applies to domestic standard variable tariffs, not fixed tariffs, and limits rates and standing charges rather than the total bill regardless of usage. That is a GB-specific protection, not a general rule for other countries. Ofgem’s price-cap guidance sets out its scope. EU consumer guidance and Australian guidance apply in their respective jurisdictions: European Commission contract guidance and the ACCC’s advice on Australian electricity prices and plans.

Is a fixed energy tariff worth it?
It may be worth paying for price stability if the fixed components and term genuinely match your needs and the estimated annual cost is acceptable. It may be a poor fit if the premium over a variable offer is too high, you expect to move before the term ends, or exit conditions are restrictive. A variable or dynamic plan can offer more exposure to price reductions, but also more exposure to increases; dynamic pricing adds the practical question of whether you can shift demand.

There is no sound way to decide from an oil-price forecast alone. Compare the contract formula and full annual cost for your location, then weigh that offer against your own need for budget certainty and flexibility.
