Don’t Accept the 2% October Price Cap Rise – Save 4.4% with Octopus 12 Months Fixed.

Written by: Sarah Chambers (Updated 24th October 2025)

Why Fixing Now Makes Sense

The Energy Price Cap went up by 2% on 1st October, but you don’t have to pay more. By choosing Octopus Energy’s 12-month fixed tariff, you can secure a rate around 4.4% below the flexible rates. As a result, a typical household could save roughly £100 a year. I know it doesn’t sound huge, but £100 is £100 I’d rather keep in my pocket for the kids’ lunches, or just not stressing about bills. Moreover, with predictions pointing to a 6% rise in April 2026, fixing now gives immediate savings and protection against future increases. In other words, acting quickly could prevent your energy bills from spiralling later.

The Octopus October v2 12-month fixed tariff is simple and flexible. In addition, it offers cheaper gas and electricity rates, and you can leave at any time with no penalty. This means you don’t have to worry about being locked in overpaying, giving you confidence and control. Equally important, it lets you respond to future changes in energy prices without being tied down.

Choosing the Right Tariff

I know it can feel stressful to pick the right tariff. Energy bills are such a large part of household costs, and nobody wants to get it wrong. That’s exactly why I follow Octopus tariffs closely and share what I learn. For example, I always check my own bills and meter readings before October—it saves me hassle and sometimes a few extra pounds. If you are already with Octopus or planning to switch, the 12-month fixed tariff will cost less than the Octopus Flexible rate and less than the October Energy Price Cap. Plus, you won’t be charged for switching if a better deal comes along later. Therefore, locking in a fixed rate now is a clear and easy choice. Ultimately, it gives you control and reassurance during uncertain times.

Meter Readings: A Crucial Step

If you have a standard meter, submitting an accurate reading before 1st October is essential. Otherwise, you could end up paying estimated charges that may be higher than your actual usage. In particular, households without smart meters should take this step to ensure accurate billing. Additionally, keeping your meter readings up to date makes switching between tariffs faster and simpler. Meanwhile, it helps you track your energy usage more closely, which can uncover extra savings.

Understanding the Energy Price Cap

The Energy Price Cap sets the maximum that suppliers can charge per unit of gas and electricity. From 1st October to 31st December 2025, the cap is:

• Electricity: 26.35p per kWh

• Gas: 6.29p per kWh

• Daily standing charges: 53.68p for electricity and 34.03p for gas, Ofgem.

These rates apply to standard variable tariffs and will change on 1st January 2026. For most households, this means a bill of around £1,755 if you stay on a standard flexible tariff. For example, here is an estimate of what I would pay in South Wales, comparing the Octopus 12-month fixed, Octopus Flexible, and Octopus Tracker tariffs.

Exploring Alternative Tariffs

If you have an electric vehicle (EV) or a heat pump, Octopus Energy offers dedicated tariffs that can be more cost-effective than standard flexible rates. Furthermore, time-of-use tariffs like Agile or Octopus Tracker may suit households with variable energy consumption patterns. However, with the anticipated 7% increase in April 2026, it’s worth monitoring these options closely. Meanwhile, if prices rise faster than expected, you can always switch back to a fixed or flexible tariff to protect your bills. In other words, you have options to adapt to changing energy costs without losing out.

Why Energy Prices Could Rise This Winter

Even though fixing your tariff now gives you savings, it’s worth knowing why energy prices could go up this winter. First, wholesale energy costs can change quickly. These are the prices suppliers pay for gas and electricity, and if they increase, it can push up your bills. Second, global events can make prices unpredictable. Conflicts or tensions in energy-producing countries can disrupt supply, which may mean higher costs here in the UK. Finally, cold weather, policy changes, or unexpected demand can also affect prices.

The good news is you don’t have to guess what will happen. By locking in a fixed tariff now, you protect yourself from surprises and know exactly what you’ll be paying this winter. At the same time, if prices drop later, you still have the flexibility to switch to a better deal.

Conclusion – Take Action Now

With the energy price cap set to rise and winter approaching, now is the ideal time to fix your energy tariff. By acting swiftly, you can lock in savings, gain peace of mind, and take control of your energy bills. Ultimately, choosing the Octopus 12-month fixed tariff offers flexibility, security, and real savings before the October increase. At the same time, it gives you the freedom to adapt if prices change later.

Don’t wait—switch to Octopus Energy’s 12-month fixed tariff today and take control of your bills before the October rise hits.
