Fuse Energy or Octopus: what should I compare?

Fuse Energy and Octopus are worth comparing on the tariff you can actually get, not just the supplier name. Start with two postcode quotes using the same annual gas and electricity consumption. Then check payment arrangements, exit fees and, if you use electricity overnight, what receives the cheaper rate.

A smaller monthly payment does not necessarily mean cheaper energy. A longer cheap window does not necessarily mean a cheaper year. The useful answer depends on the home, the contract and when the electricity is used.

Compare the same annual use, not two monthly payments

Take annual gas and electricity consumption in kWh from recent bills. Use the same figures and the same payment method for both quotes. Citizens Advice explains the tariff choices. Compare unit rates and daily standing charges for each fuel, together with the length of any fix and its exit conditions.

For a single-rate tariff, the comparison starts with annual consumption at the quoted unit rate, plus the standing charge for the year. If you are comparing an overnight tariff, split electricity into the periods charged at each rate. Include daytime household use, not only what goes into the car.

Keep any introductory reward separate from recurring energy costs. A one-off benefit cannot tell you whether a tariff will still suit the household after it has been used.

You can use our Octopus tariff comparison tool to check the Octopus side, then compare those figures with the actual Fuse home-energy quote. The Octopus tool is not a live Fuse tariff feed.

A fixed tariff and a fixed payment are different choices

A fixed-price tariff concerns the energy rates in your contract. A fixed monthly Direct Debit spreads expected costs into steadier payments. A variable Direct Debit pays the amount billed and can be much larger in winter. You can have a fixed-price tariff without paying an identical amount every month.

Fuse's home-energy page advertises variable or fixed payments. Confirm which arrangement your own quote includes, how the initial collection is calculated and whether the collection date suits you before accepting it.

Octopus explains fixed monthly payments and paying each bill in full. A variable Direct Debit may need to be requested from its team; do not assume every option is available in the signup journey. If readings are missing, the bill collected can still be estimated and corrected later.

Our Octopus Direct Debit guide explains the payment mechanics in more detail. Choose a tariff on its rates and terms, then check that the payment arrangement is affordable through winter.

If you have an EV, compare the whole-home pattern

Fuse's tariff guide describes single-rate and off-peak tariffs, with fixed and variable price options. Its tariff guide describes an overnight discount for household electricity, rather than a benefit limited to charging the car. Check the exact quoted tariff's meter requirements, rate periods and how the hours are expressed before setting a schedule.

Octopus Go is a different eligibility decision. It requires an owned or long-leased battery electric vehicle or plug-in hybrid charged at the supplied home, together with a suitable communicating smart meter. Its fixed whole-home off-peak window is 00:30 to 05:30. A dedicated home charger is not itself a requirement, and a charger or battery alone does not satisfy the vehicle condition.

Intelligent Octopus Go needs an eligible vehicle charging primarily at the supplied home and a supported vehicle or charger connection. Its fixed whole-home night window is 23:30 to 05:30. For smart EV charging outside that window, confirm the household rate applicable to your account with Octopus before shifting other loads, then check the corresponding billed periods against the smart-tariff terms.

Do not choose between these routes from the car's cheap rate alone. Count daytime electricity, the standing charge, realistic home-charging demand and what can safely be shifted. The low-mileage EV guide explains why a small amount of home charging can change the result.

If you have a home battery but no EV, establish tariff eligibility before using an EV night rate in the calculation. A battery is not a substitute for the vehicle required by Go or Intelligent Go. Check the battery-only guide alongside the applicable tariff terms.

You do not have to move both fuels together

Both suppliers' domestic terms describe supplying gas, electricity or both according to what is agreed. That does not guarantee that every tariff combination will be offered to every address. Check which fuel or fuels the quote actually changes.

If an Octopus electricity tariff already suits your EV, a separate gas quote may be worth considering. You do not need to replace an electricity arrangement merely because another supplier has an attractive gas offer. Our separate gas and Intelligent Go guide covers the checks before changing gas alone.

If the quote shows only one fuel when you expected two, stop and ask the supplier to confirm the intended supplies before accepting. Do not assume a displayed gas quote also changes electricity, or complete a dual-fuel switch when you want electricity left alone.

Check the contract, not a blanket exit-fee claim

Fuse's terms say some contracts have exit fees, with the amount disclosed at signup and exceptions including the cooling-off period, the final 49 days and variable-rate contracts. Use the actual tariff documents rather than assuming one fee applies to every Fuse deal.

Do the same for Octopus using its domestic terms and your tariff documents. Read the quoted tariff information and applicable terms instead of treating every Octopus product as fee-free. If your existing fixed tariff is ending, our 45-day versus 49-day guide explains why an account renewal window and the exit-fee window are different questions.

Save the tariff name, end date, rates, standing charges, payment arrangement and fuel selection before confirming a change. Keep the new supplier's confirmation so you can check that the first statement matches the intended contract.

Which should you choose?

Choose the offer whose full costs and conditions work for your home. Fuse deserves a proper quote comparison; Octopus deserves the same. Neither supplier name proves that its deal is cheaper for your postcode or that its overnight arrangement fits your routine.

For a straightforward home, annual cost, payment arrangements and exit conditions may settle the choice. For an EV, battery, heat pump or export account, check the relevant eligibility and billing model before treating a low rate as a household saving.

If you are considering a new Octopus signup, compare the tariff first. Only if it still suits the home should you continue to the referral page for the direct signup guidance. Existing Octopus customers comparing a renewal should use their account's tariff options instead.
