How long do Octopus fixed tariffs last?

Most fixed deals run for around 12 months, though availability and terms can change. Always check the exact end date shown in your quote before you switch.

Do fixed tariffs protect me from energy price rises?

Yes. Your rates are locked for the term, so if market prices rise, your unit rates and standing charges won’t increase during the fixed period. If prices fall significantly, a variable tariff might become cheaper, but exit fees could apply if you leave early.

Does the Ofgem energy price cap apply to fixed tariffs?

The Ofgem Energy Price Cap applies to default variable tariffs, not to most fixed deals. Fixed tariffs can be priced above or below the cap depending on market conditions.

How long does it take to switch to an Octopus fixed tariff?

You can complete your application online in minutes. The actual switch usually completes within a few working days. There’s a 14-day cooling-off period, and your energy supply won’t be interrupted.

Octopus Energy Fixed Tariffs for UK Homes

Q: What is an Octopus Energy fixed tariff?

A fixed tariff from Octopus Energy sets your unit rates and standing charges for a defined period (for example, 12 months). Your monthly cost can still vary with usage, but the prices you pay per kWh and the daily standing charge won’t change during the fixed term.

Q: Are both unit rates and standing charges fixed?

Yes. On a fixed-rate plan, the electricity and gas unit rates (p/kWh) and the daily standing charges (p/day) are fixed for the duration of the contract, unless taxes or regulatory changes outside the supplier’s control are introduced.

Q: Do exit fees apply if I leave early?

Exit fees may apply on fixed tariffs if you switch before the end date. Some deals are fee-free, but many include a per-fuel charge. We’ll show any exit fees clearly during your quote.

Q: Can I get a fixed tariff with a smart meter or Economy 7?

Yes. Fixed options are typically available for standard credit meters, smart meters and two-rate meters (such as Economy 7). Availability and rates vary by region and meter type.

Q: Will there be a credit check?

A soft credit check may be carried out for Direct Debit payment plans. This helps set up your account and choose an appropriate payment schedule.

Is a fixed tariff right for you?

Compare Octopus fixed vs variable tariffs

Fixed: Locked rates for the full term; may include exit fees if you leave early.
Variable: Rates can go up or down with the market; usually no exit fees.

Because fixed deals aren’t limited by the Ofgem Price Cap, they can be priced above or below the cap depending on market conditions. That’s why it’s important to compare today’s live offers.
