Are You Paying Too Much for Energy? It’s Time to Switch to Octopus Energy

Tired of an energy supplier that offers poor service and resists change? If so, it’s time to consider Octopus Energy. I made the switch almost 8 years ago, and it’s been one of the best decisions I’ve made for my home and wallet.

The UK energy market needs to change, and we need suppliers who fight for lower prices, better customer service, and a greener future. Octopus Energy does just that. They champion their customers, constantly push for fairer energy policies. Octopus Energy offers a range of tariffs, including fixed, flexible and smart options. Tariffs, eligibility and pricing can change, so please check the latest official Octopus pages to see what suits your home and usage.

My website is just my own personal review of what Octopus has to offer at the time of writing. I hope it helps.

Why I Switched to Octopus Energy

I’m a mum of three school-age daughters, and managing energy costs has become a huge priority for my family. Energy now feels like a luxury commodity, and I’m more determined than ever to cut costs and get the best value for money.

I switched to Octopus Energy nearly eight years ago, and it’s given me more control over my energy bills than I ever had with my previous supplier. Octopus genuinely cares about its customers and fights for fairer energy prices, not just for their customers but for the entire UK market.

What’s Next? Understanding Octopus Energy Tariffs in 2026

Let’s break down Octopus’ energy tariffs and how they can help you save money this year. No matter your home’s energy needs, there’s a tariff that fits and the best part? You’re never locked in.

If you are a new Octopus customer, finding the best energy deal and deciding whether to take an Octopus Energy fixed tariff, stick with an Octopus flexible tariff, or move to one of their smart tariffs can seem slightly overwhelming, but I am here to help. I will give you an overview of the available Octopus tariffs and explain how they could help you save money on your bill.

 What Octopus Energy Tariffs are available when switching suppliers in 2026?

When you switch from your existing energy supplier to Octopus Energy as a new customer, you choose one of two tariffs;

• Octopus Energy Flexible Tariff – The price will change every 3 months and follows the Energy Price Cap.
• Octopus Energy 10 Months Fixed Tariff. – The price is locked in for 10 months.

There is an exit fee of £50 per fuel type on the Octopus 10-month fixed tariff.

Do you need a smart meter to switch to Octopus Energy?

No, you don’t need a smart meter to switch to Octopus Energy as a new customer. The Octopus 10-month fixed and flexible tariffs do not require customers to have a smart meter.

• Once your switch to Octopus Energy is complete, you can move to a smart tariff if you have a smart meter.

If you consider installing a smart meter, Octopus has several innovative tariffs.

Should Customers Fix Their Octopus Energy Tariff Now Or Stick To The Price Cap?

It isn’t an easy decision, and everyone’s home energy needs and budgets are different. All I can tell you is that we need to hope that this conflict ends if we want to stop prices from increasing by the time we get to the October 2026 Energy Price Cap.

If you fix now, you will pay more than the April 2026 Price Cap, but you may pay less than the July and October 2026 Energy Price Caps. No one knows. I didn’t expect this conflict to start. I was horrified when I opened my news feed on the 1st March. All we need is another war to cause so much destruction and fear around the world.

Analyst on the 16th March 2026 shows a predicted 16% price increase in the Energy Price Cap by the time we get to October 2026. This information is taken from the average predictions from EDF, British Gas and E.on Next’s Price Cap Forecasting Services. (You can double-check this on Martin Lewis’ website. )

Energy Price Cap Predictions for 2026 – Will They Change?

I can guarantee the Energy Price Cap Predictions will change. Their crystal ball predictions are changing constantly right now. No one knows when or how the conflict in Iran will end, or what will happen next.

Will the Energy Price Cap Go Up in 2026?

According to almost all the analysts from the major energy suppliers, predictions are that the Energy Price Cap will spike by around 13% in July 2026.

The unnerving thing is, we don’t know what will happen next in the world.  As it stood on the 16th March analysists were predicting a further 2.7% rise in October 2026, but the world changes so fast, who knows?

When Will Ofgem Announce the Next Energy Price Cap?

 The July 2026 Energy Price Cap will be announced by Ofgem on 27th May 2026.

Ofgem reviews the Energy Price Cap every three months, adjusting it based on wholesale energy prices.

Final Thoughts: Fix or Stay Flexible?

• Fix, but you will pay more than the April Price Cap.
• There is a £50 exit fee per fuel type on the Octopus fixed tariff.

Stay Flexible if you:

• Know that the Octopus Flexible rate will change on the 1st July and 1st October 2026, and you don’t want an exit fee.
• Are you okay with possible price increases in the winter?

Since making this TikTok video on Friday, 13th March 2026, Octopus has lowered their exit fee on the Octopus Fixed Tariff to £50 per fuel type, and the Octopus Fixed is now for 10 months instead of 12. I think this is better as it lowers the risk of fixing. Yes, 12 months may look better if prices stay high, but if they drop, you will have a lower exit fee or if you stick to a shorter period to wait to switch tariffs.

Tariffs are constantly changing, so please check before switching tariffs.

Octopus Energy FAQ about switching as a new customer.

 

When I switch to Octopus using a referral link, how long does it take to get my £50 credit?

You’ll get your £50 credit after you make your first direct debit payment. Sometimes, it takes a couple of days for it to appear in your account balance.

You will get a quote by following the link and answering a few quick questions. Select to have the quote on screen rather than send it to you by email. (You may miss out on the £50 credit if your sign-up isn’t tracked.)   If you are happy with the quote, you can confirm if you wish to complete the switch.

How long does it typically take to switch to Octopus Energy?

Once you’ve clicked to switch, you should be an Octopus Energy customer within 5 days, although sometimes it could take as little as 3 days.

Even though switching to a new Octopus Energy tariff usually happens very quickly, you have a 14-day cooling-off period, which is standard practice in the energy industry. This period gives you time to reconsider your choice without penalty, ensuring you’re completely satisfied with your decision.

Will my energy supply be disrupted when I switch to Octopus Energy?

When I switched to Octopus Energy from British Gas, I had amazing communication with Octopus Energy. They took care of it all, it was a hassle-free experience and you won’t see any change or disruption to your supply.

All you need to do is pick up your Octopus Energy tariff, supply your meter readings, and cancel your direct debit after your final bill has been settled.

 I’ve done lots of videos about switching to Octopus Energy on TikTok that may help.

How does Octopus Energy ensure you have a hassle-free experience when switching tariffs?

Honestly, I have often switched Octopus tariffs, it is hassle-free. I even changed my mind about three hours after switching to a new tariff, and they switched me back on the same day.

They seamlessly manage the entire switching process. They are so friendly and transport and I think the key lies in your account being allocated to a specific team. Each time you email the same team deals with that enquiry. They are given the authority to deal with everything. So there’s no being passed from pillar to post, dealing with someone new each time.

Their commitment to genuinely caring about the customer experience is reflected in their dedication to customer satisfaction.

For your gas supply with Octopus, you only have 3 options;

Before choosing an Octopus smart tariff, you should consider your;
