Lock in your electricity and gas prices for a full year with Octopus 12M Fixed 2026. This popular tariff offers peace of mind from market fluctuations, making budgeting simpler and more predictable.
As we navigate 2026, managing household budgets remains a top priority for many UK homes. Energy costs, in particular, can be a significant concern, with market fluctuations often leading to uncertainty. This is where a tariff like Octopus 12M Fixed 2026 can offer a welcome solution. If you're looking for stability and predictability in your energy bills, read on to discover if this fixed-rate tariff is the right choice for you.
Octopus 12M Fixed is a straightforward, fixed-rate energy tariff designed to give you peace of mind over your electricity and gas costs for a full year. When you sign up for this tariff, Octopus Energy commits to locking in your unit rates (the price you pay per kilowatt-hour, or kWh, of energy used) and your daily standing charges for 12 months. This means that, regardless of what happens with wholesale energy prices over that period, your rates will remain constant.
In simple terms, you'll know exactly how much you're paying for each unit of energy and your daily fixed charge, making it much easier to plan your finances without the worry of unexpected price hikes.
Upon switching to Octopus 12M Fixed, your personalised unit rates and standing charges for both electricity and gas (if you take both fuels) are set for a full 365 days. Your monthly bill will still vary based on how much energy you actually consume – use more, pay more; use less, pay less – but the cost per unit remains fixed. This contrasts sharply with variable tariffs, where your unit rates can go up or down at any time, often in response to broader market conditions.
The 12-month duration provides a significant window of stability, shielding you from potential energy price volatility. As your contract approaches its end, Octopus Energy will contact you with options for your next tariff, giving you ample time to review and choose what’s best for your household going forward.
This tariff is an excellent choice for a wide range of households, particularly those who:
The most compelling advantage is the certainty it brings. With fixed rates, you can forecast your energy expenditure more accurately. This is invaluable for household budgeting, allowing you to allocate funds confidently without the looming threat of sudden price changes.
The energy market can be unpredictable. By fixing your rates for 12 months, you're insulated from any wholesale price increases that might occur during your contract period. This means you won't be caught off guard by sudden spikes in your per-unit costs.
Knowing your rates are secure for a year offers significant peace of mind. You can use your energy without constantly worrying about what the next market announcement might bring, freeing you up to focus on other aspects of your life.
Octopus 12M Fixed is easy to understand. There are no complex formulas or variable rates to track; just one clear price per unit and a standing charge for the duration of your contract.
As with many fixed-term contracts, Octopus 12M Fixed comes with an early exit fee. If you decide to switch away from this tariff before your 12-month contract ends, there is a £50 fee per fuel. This means if you have both electricity and gas on the tariff, the total early exit fee would be £100.
This fee is designed to cover the costs Octopus Energy incurs from purchasing energy for you at a fixed price. It's an important factor to consider. However, it's worth noting that this fee is often waived if you're moving house and continue to take Octopus Energy at your new property, or if you're switching to another Octopus tariff nearing the end of your contract.
It's crucial to understand that energy unit rates and standing charges vary significantly based on several factors, including your specific region in the UK, your payment method (e.g., direct debit), and current market conditions. As such, we cannot provide specific unit rates or standing charges here.

While the stability of a fixed tariff is appealing, it's always wise to consider your personal circumstances:
If you're comfortable with market fluctuations and believe prices might drop significantly in the near future, a flexible (variable) tariff like Octopus Flexible might offer lower prices if the market moves favourably. However, it also carries the risk of price increases.
Households with high energy consumption often find fixed tariffs particularly beneficial, as they lock in the price for a larger volume of energy. For very low users, the early exit fee might feel like a larger barrier if you anticipate needing to switch.
In 2026, the energy market continues to present challenges and uncertainties. For many, the security offered by a fixed tariff outweighs the gamble of waiting for potential price drops on a flexible tariff.
Beyond the tariffs themselves, choosing your energy supplier is about customer experience. Octopus Energy consistently receives high ratings for its award-winning customer service, commitment to renewable energy, and innovative approach to tariffs. Switching is designed to be simple and hassle-free, with a dedicated team ready to support you every step of the way.
