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

Tired of an energy supplier that overcharges, offers poor service, and resists change? If so, it’s time to consider Octopus Energy. I made the switch six 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, and help households save money all while being one of the cheapest energy suppliers in 2025.

How Can Octopus Energy Help You Save Money?

No exit fees – You can swap tariffs at any time.
Fair, transparent pricing – no overpriced loyalty penalties
100% renewable electricity – better for the planet
Excellent customer service – award-winning support

If you’re still paying price cap rates with your current supplier, you are very likely overpaying for your gas and electricity. In this Octopus Energy Tariff Review, I’ll walk you through Octopus’ 2025 tariffs, how they compare, and how they can help you take control of your energy bills.

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 seven 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.

Written by Sarah Chambers

Updated 10th April 2025: The Octopus 12-month fixed April 2025 v2 is approximately 10% below the April 2025 Price Cap and there are no exit fees. There was a short 48-hour flash deal this week, but it had exit fees. That’s now gone, and Octopus is back to its usual no-exit fee fixed tariffs which is my preferred Octopus policy.

Why make the switch to Octopus Energy?

I recommend Octopus Energy because they truly care about their customers and the environment. Their mission isn’t just about selling energy, it’s about making it cheaper, fairer, and greener.

Here’s a new customer quote from the 22nd April 2025.

Are Octopus Energy Prices Going Up? Should You Fix Your Tariff Now?

Wholesale energy prices are starting to fall, and Octopus has jumped on that by offering a 12-month fixed tariff that’s 10% cheaper than the April Price Cap (based on typical use) with no exit fee.

By fixing it now, you’re not overpaying for the next three months. You will be locking in a significant saving right away. Even with the predicted 6% drop in the price cap this July, this deal still works out cheaper over the next 12 months.

That 10% discount keeps money in your pocket now, when everything else seems to be going up. And even if prices dip a bit further in the short term, you’re still ahead for at least the next six months. If you are now just swap tariffs and take the cheaper one.

If you’ve been thinking about switching to Octopus, this is a great time to do it.

The Ofgem Energy Price Cap sets the maximum rates for standard variable (flexible) tariffs and went up by 6.4% increase from 1st April 2025. (Reflected in the quote above.)

Why Is the Energy Price Cap Rising?

The Energy Price Cap is updated every 3 months, based on wholesale energy costs. Since wholesale prices have increased, a price cap rise is expected:

April 2025: Rose by 6.4% on 1st April 2025.
July & October 2025: Some forecasts predict a 6% reduction in July + a 1% increase in October.

If this happens, staying on the Octopus Flexible tariff will still mean higher bills.

Best Octopus Energy Tariff for New Customers: Fixed or Flexible?

If you’re switching to Octopus Energy as a new customer, you can choose between:

1️⃣ Octopus Energy Flexible Tariff

• Prices change every 3 months, following the Ofgem Energy Price Cap.
• No exit fees – switch anytime.

2️⃣ Octopus Energy 12-Month Fixed Tariff

• Fixed rates for 12 months – protects against price hikes.
• No exit fees – switch anytime
• £5o exit fee per fuel type.

Cheaper than the April 2025 Energy Price Cap by around 10%.

💡 Octopus Energy Savings in 2025 as a new customer. 💡

🔹 £50 new customer bonus = 2.7% off April 2025 price cap
🔹 April 2025 rates = 10% below the new price cap.
🔹 Total saving: Nearly 13% compared to the April price cap (based on typical use-using figures for South Wales.)

Switching to the Octopus 12-month fixed tariff means bigger savings than just following the price cap! 🔥♻️

(Octopus has discontinued the Loyal Octopus 12-month fixed and instead has gone for a much bigger saving for everyone.

Should New Customers Fix Their Octopus Energy Tariff Now?

✅ Fixing now locks in a lower price saving you around 10% compared to April’s Price Cap with no exit fee.
✅ Fixed tariff is cheaper than forecasts for the next 12 months even with the predicted price reductions.
✅ New customer £50 switch credit makes it even better value.

📢 Right now, the Octopus Fixed rate is cheaper than both the April and predicted July 2025 Flexible rates.

Below is my comparison based on the Octopus 12-month fixed (with exit fees) versus the Energy Price Cap for 2025 with a 6% predicted drop in July 2025. (Based on EDF Price Cap Forcast of 31st March 2025.)

Octopus Energy Fixed vs. Flexible:

What’s the Best Tariff for New Customers?

The Energy Price Cap increased by  6.4% on the 1st of April 2025. The current Octopus Energy 12-month fixed tariff is cheaper than the Energy Price Cap until at least 2026 if analyst predictions for July and October 2025 are correct. (Flexible tariff)

In September  Octopus Energy sent emails to millions of its customers on the Octopus flexible tariff advising them they could save money by taking the Octopus 12-month fixed tariff. They did the same in February 2025 as this advice applies now more than ever, with volatility still surrounding the energy prices and the energy price cap will go up again in autumn 2025.

For a typical UK home, in South Wales (prices will vary depending on your location) here’s how the numbers compare:

🔹 Octopus 12-Month Fixed Tariff: £1,675 per year
🔹 April 2025 Flexible Tariff: £1,863 per year
🔹 April 2025 Energy Price Cap: £1863 per year

👉 If you stay on the Flexible tariff, you could end up paying at least £188 more over the next year based on typical usage. Fixing now offers protection — especially with so much global uncertainty.

If prices were to fall sharply mid-way through your fixed term, you could still switch as there are no exit fees.

Here’s a snapshot of some Octopus tariffs available to new and existing customers today and the unit reach for each. If you don’t mind volatility and have a smart meter, the Octopus Tracker tariff may still outperform the tradional rates.

	Octopus Flexible Tariff (April 2025 Price Cap)	Octopus 12 months Fixed Tariff 2025 - April v2	Tracker Tariff April 2025 v1
Gas	7.12p	6.3p	5.29p
Electricity	27.61p	24.15p	24.43p
Rates per kWh	1st April to 30th June 2025	Fixed for 12 months. NO EXIT FEE.	Rate change daily - 22nd April 2025

These figures are based on South Wales. Prices will vary depending on your geographical location.

I haven’t included the standing charge as these vary throughout the country. If you want to take a look at how standing charges and unit prices are changing throughout the country and who gets hit hardest, look at my other blog post here.

Summary: Should You Switch to Octopus & Fix Your Tariff Now?

✔ Octopus Energy prices on the flexible rates went up on 1st April 2025
✔ The 12-month Fixed Tariff is cheaper than the forecasted price cap rates for 2025.
✔ New customers get a £50 switch bonus for extra savings
✔ There’s no exit fee!

🚀 Best deal for new customers? Switch to Octopus Fixed now as sit back. (Unless you want to ride it out on smart tariffs which I have written about lower down the page – you’ll need a smart meter for these.)

Energy Price Cap Predictions for 2025 / 2026 – Will They Change?

The energy market is unpredictable, and no one knows exactly what will happen in 2025. However, based on wholesale market trends and analyst predictions, we can get a rough idea of where things are heading.

Will the Energy Price Cap Go Up in 2025?

According to EDF’s latest forecast (31st March 2025) which Martin Lewis also references, the Energy Price Cap is expected to rise:

• A  6% reduction is forecast for July
•  1% increase from October 2025.

This means that households on the Flexible tariff will see higher bills from April and throughout 2025.

When Will Ofgem Announce the Next Energy Price Cap?

 The July Energy Price Cap will be announced by Ofgem on 25th May 2025,

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

Should I Fix My Octopus Energy Tariff Before July 2025?

If you’re debating whether to fix your tariff or stay on the Flexible rate, here’s why fixing could be the better choice:

• Fixing now locks in the reduced rates now. They are around 10% cheaper than the April 2025 increase.
• The 12-month Fixed Tariff is cheaper than all the predicted price caps for 2025 and 2026.
• There are no exit fees, so it’s a no-brainer when comparing the fixed to the flexible tariffs.

Right now, the Octopus 12-Month Fixed Tariff is around 10% less than the April Flexible rate.

I would suggest seriously considering the Octopus 12 months fixed April 2025 v2. Why pay more especially with the discount being so high? Unless you are prepared to move to say the Octopus Tracker or Agile tariff where prices change each day this is a good saving right now.

What Does Martin Lewis Say About Fixing Energy Prices?

Martin Lewis recommends fixing your energy deal if you can get a fixed rate of 5% less than the April 2025 Price Cap.

The Octopus 12-Month Fixed Tariff is around 10% below the April price cap, meaning it’s a solid choice.

Martin Lewis’ key advice: If you’re risk-averse and want stability, a fixed rate is a good option especially if the Energy Price Cap is rising. He is referring to the Energy Price Cap at the Pants Cap!

Final Thoughts: Fix or Stay Flexible?

Fix if you want:

• Protection from April’s 6% increase.
• A predictable bill for the next 12 months.

Stay Flexible if you:

• Want to gamble on prices dropping later in 2025?
• Are you okay with possible price increases in the autumn?

Best deal for 2025? Fix now and escape April’s rise, plus grab your £50 new customer switch credit.

Octopus Energy FAQ about switching as a new customer.

How to get £50 credit switching to Octopus Energy.

Join the Octopus Energy family using my 2025 referral code tough-deer-484, and they’ll drop a cool £50 credit into your account—no tentacles required! Just tap to switch, and your £50 bonus will 

swim its way to you within about 4 weeks. Easy peasy!

Since switching, I’ve saved hundreds of pounds on my energy bill. I have an Electric Vehicle, but anyone can save money with Octopus Energy. They’d rather pay customers to use energy when it’s windy than let it go to waste!

Octopus won’t lure you in with a new customer-only offer. (No sharks here!)  Switching to Octopus means friendlier service and a sustainable future. As an ex-British Gas customer, I’ve seen a complete contrast.

• Ofgem has proposed allowing companies to hide or even bar their best deals from loyal customers
• Octopus disagrees and has pledged that its best and lowest tariffs will be available to existing customers, not just new ones.

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

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.

What is the price of the Octopus Flexible Tariff in April 2025? ( 1st April- 31st June 2025)

The Octopus Flexible tariff is a variable rate that follows the Ofgem Energy Price Cap.

The Octopus Flexible tariff prices are below the Ofgem rates for the April cap. Prices vary depending on where you live in the country.

Octopus April 2025 Flexible rate.
Electricity ⚡️	Gas 🔥
27.61p per kWh	7.15p per kWh.
Daily standing charge 50.42p.	Daily standing charge 31.44p.
Prices vary based on geographical location.

These are the Octopus Flexible rates per kWh in South Wales.

Here are the April 2025 Octopus Flexible rates for all 14 regions around the UK.

You can find prices for the April 2025 Octopus Flexible rates if you pay by another method in this recent Octopus Energy blog post.

Is Octopus Energy introducing a standing charge-free tariff for lower energy users?

No at the moment Octopus Energy hasn’t indicated that it will introduce an Octopus tariff without a standing charge.

Ofgem has not introduced the tariff requirement for zero standing charges. Instead on the 12th of December, they simply announced they are exploring the option.  Octopus has indicated that it must assess the impact of offering zero standing charges after seeing further details from Ofgem.

It is important to remember that the standing charge won’t disappear; it will simply be added to the unit price of energy for consumers to pay. However, if you are a low-energy user, you will use fewer units of energy, so the overall cost of your bill should be lower.

What Octopus Energy tariffs are available for gas?

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

• Flexible Octopus.
• Octopus 12 months fixed.
• Octopus Tracker tariff (You’ll need a smart meter for this.)

How many Octopus Energy tariffs are there for electricty?

There are 2 Octopus Tariffs you can switch to for your electricty that do not need a smart meter;

Octopus Smart tariffs.

Octopus Energy offers a range of tariffs to suit your energy needs and help you save money.

With smart and flexible options, switching to Octopus Energy means you can find the best deal for your lifestyle and start cutting your energy costs today.

So what’s the cheapest Octopus Energy tariff?

Before choosing an Octopus smart tariff you should consider your;

• Aversion to risk.
• Ability to be flexible in your home energy use.
• The green tech you have in your home. (You don’t need any for two of the tariffs.)
• The time of year. (Some tariffs perform better in the summer or winter.)

This article in Bloomberg, “We are energy nerds,” may inspire you if you like green tech. (I’m featured in the article as an energy nerd.)  You do not need to be geeky about your energy to switch to Octopus, but if you’d like help finding the best Octopus tariff, I am more than happy to help.

Octopus Energy Tracker. 

I am on the Octopus Tracker tariff for my gas supply, which is the simplest way to experience an Octopus smart tariff.  

3 Reasons I always recommend the Octopus Tracker tariff.

1. The Octopus Tracker tariff requires no green tech and no clock-watching.
2. There is just one flat rate, which changes at midnight and is linked to the previous day’s wholesale energy prices. The tracker tariff has no time lag.
3. If you want to beat the Energy Price Cap and benefit from drops in energy prices first, then it’s an easy tariff to switch to and lower your bill.

You can be on Octopus Tracker tariff for gas, electricty or both. Octopus Energy allows you to split your fuel types between different Octopus tariffs.

• Ideal for: Anyone. You don’t need any green tech and it’s the only smart tariff that can be used for gas and electricty. (You don’t need to have both energy types on the same tariff.) If you are prepared to ride with the wave of wholesale energy prices in real-time to save money this flat rate which changes every day at midnight is for you.
• Would I recommend this tariff? Yes, it is easy to enter Octopus smart tariffs for anyone who wants to reduce their energy bill right now.
• Advantages: The Octopus Tracker tariff isn’t linked to the Energy Price Cap. With this tariff, if wholesale energy prices fall, you make the savings immediately. Conversely, you also feel the pinch if wholesale energy prices go up.
• Disadvantages: This isn’t a set-and-forget tariff. You have to monitor the prices at least weekly to ensure it’s still a valid way of saving money compared to the Energy Price Cap. The standing charge is currently higher.

Octopus Energy Tracker tariff for today (22nd April 2025) and gas tracker rates for the last week.

On the Octopus Tracker tariff, today’s unit rate is 5.29p Wh for gas and 24.43p per kWh for electricity.

The price is based on the South Wales region and may vary depending on location. The standing charge is the same as all the other Octopus tariffs. For example, South Wales has 62.06p per day for electricty and 29.77p per day for gas. (Which hasn’t gone down as the tariff is still based on December figures.)

If you opt for the Octopus Tracker tariff, your daily rates will change but the formula and the standing charges are set for the 12 months your terms are fixed. The latest version of the tariff is Octopus Tracker April 2025 v2.

Octopus Energy Agile tariff

Octopus Agile is a unique tariff ideal for renewable energy enthusiasts. It is a variable tariff where the rates you pay for electricty change half-hourly based on wholesale energy prices. If the winds blow and there’s excess energy on the grid you could get paid to use it. If there is high demand the rate goes up. You’ll use cleaner, greener energy and save money.

• Ideal for: Anyone. You don’t need any green tech. If you can shift some of your energy use to the cheaper half-hourly slots you should save money on your energy bill. You’ll have to be flexible with your energy use. Eagle eye bargain-saving customers will love this tariff.
• Would I recommend this tariff? Yes, Octopus Agile requires no green tech. If you have battery storage, you can reduce your energy bill, if you don’t, you can too!
• Advantages: You aren’t stuck on the Energy Price Cap. If it’s windy and there’s excess energy you can get cheap or even free energy. Several times this year Octopus customers have been paid to use energy. If you can be flexible with your energy use with no green tech you can drastically reduce your average price per kWh.
• Disadvantages: It is not a set-and-forget tariff you have to manage your energy use actively. Unless you have Home Assistant or a third-party software that can help automate it.

Top pick of Octopus Energy EV tariffs in 2025.🌟

Intelligent Octopus Go is my top pick for 2025. Intelligent Octopus Go rates are cheaper, 7.0p instead of 8.5p on Octopus Go. The off-peak rate spans a minimum of six hours versus five on Go.

Octopus Energy Go.

If you own an Electric Vehicle and can charge it at home, you should consider a dedicated EV tariff.  On the Octopus Go tariff, you can get an off-peak rate well below any Economy 7 or domestic energy tariff.

• Ideal for: Anyone with an Electric Vehicle who can charge at home at night.
• Would I recommend this tariff? Yes, I would recommend this tariff if you don’t qualify for the intelligent version. Octopus Go provides 5 hours of off-peak charging between 00.30 and 05.30 at 8.5p per kWh. This should be enough time to top up your EV each night on a cheap tariff.
• Have I been on this tariff myself?: Yes, before the launch of Intelligent Octopus Go I was on Octopus Go.
• Advantages: Octopus Go is simple to use. All you need to do is set your timer once on your EV or EV charger and plug it in each night. The whole house, including your home battery if you have one, gets to use the off-peak, which will help reduce your overall energy bill.
• Disadvantages: Four hours may not be enough if you regularly need to charge your battery from low to fully charged.

Intelligent Octopus Go.

If you have an eligible EV or EV charger Intelligent Octopus Go wins hands down. You’d only opt for Octopus Go if you are not eligible for Intelligent Octopus Go. It provides a way of charging your EV at home at the greenest time for the grid.

• Ideal for: Anyone with a compatible EV or EV charger who can charge at home at night.
• Would I recommend this tariff?: Yes, Intelligent Octopus Go is the cheapest EV-dedicated tariff Octopus has. It’s 7.0p per kWh for a minimum of 6 hours a night between 11.30 pm and 5.30 am. Enough to add a large charge to your EV each night.
• Have I been on this tariff myself? Yes, for 2 years. It is my current tariff. I charge my EV and home battery at night for 7.0p per kWh.
• Advantages: Intelligent Octopus Go is simple to use. In the Octopus app you set the level of charge you want and buy when and Octopus does the rest. Need more than 6 hours of EV charging? Octopus will allocate additional off-peak slots.  If you arrive home empty and need it fully charged for the next morning, that will be done all at the 7.0p per kWh rate. The whole house gets the off-peak too, including your home battery if you have one.  There is no restriction on your export tariff.  I export on Outgoing fixed at 15p per kWh.
• Disadvantages: You need a compatible EV or EV charger.  Completing the test charge can be fiddly to get onto the tariff but it usually doesn’t take long. There are occasional glitches as it’s a beta tariff.

Octopus Flux Tariff.

Octopus Flux customers are rewarded for exporting electricity at peak times and importing electricity off-peak. It is a dual-band tariff with one standing charge.

• Ideal for: Anyone with solar panels or solar panels combined with battery storage.
• Would I recommend this tariff? Yes, but only if you export over 40% more than you import.
• Have I been on this tariff? No, I had my solar and battery installation in October 2023. Over winter this isn’t the tariff to be on. I did consider it for the summer but Octopus has lowered the export rate and increased the import rate since 1st April. I am happy with my current tariff.
• Advantages: There is a much higher export rate on Octopus Flux. Time your export to the peak period you’ll make more money than on a standard outgoing tariff. If you have either a large solar array or a large home battery plus your import is low then you can maximise your solar export income during the spring and summer months.
• Disadvantages:  If I import more than I export this wouldn’t be the best Octopus tariff as the import rate is quite high compared to other smart tariffs. It requires a slightly more hands-on approach compared to the Intelligent version of the tariff. (Unless you are using Home Assistant)

Intelligent Octopus Flux is a combined import and export tariff. It’s for customers with a compatible home battery and solar panels. The rates of your import and export match on Octopus Flux.

• Ideal for: Anyone with a GivEnergy battery and solar panels.
• Would I recommend the tariff? Yes, but it would have been a firmer yes last summer before the July 2024 price changes. Now, you have to do a little more calculation to make sure it is the best tariff for you. If you want to be completely hands-off and you don’t have an EV that qualifies for an EV tariff this is a plug-and-play tariff which is ideal for the spring and summer.
• Have I been on this tariff? No, I have a GivEnergy battery but I also have an EV. I prefer the ease of the tariff I am on. It has a lower import rate combined with a flat export rate, which doesn’t change throughout the day. That’s just my personal preference.
• Advantages: Octopus automates everything. The import and export rates are the same. It’s a one-in and one-out tariff which could result in a zero energy bill. However, if you export more than you import at peak times you’ll start to make a credit on your energy bill. During the summer you should easily be able to do and it is all automated.
• Disadvantages: The import rate is quite high. You hand over the control of your home battery to Octopus. This could be seen as an advantage or disadvantage. It is, however, easy to switch this control off. I believe it’s the same as on Intelligent Octopus Go. I  turn off the smart controlling of my EV in the Octopus app.

Cosy Octopus Tariff.

Cosy Octopus is an Octopus Energy tariff designed for heat pump owners. It is a variable time-of-use tariff with three price dips during the day. The dips are “boost periods” from 04:00 – 07:00, 13:00 – 14:00 and 22.00 to 00.00. There is also a “peak period” from 16:00 – 19:00. Outside these times there is another price per kWh. So in total, there are 3 pricing periods, along with a standing charge.

• Ideal for: Anyone with a heat pump.
• Would I recommend the tariff? Yes, if you have a heat pump it looks like a good option. In winter especially with the additional boost period between 10p and midnight.
• Have I been on this tariff? No, I don’t own a heat pump yet.
• Advantages: The boost periods will help all-electric homes who rely on electricity to heat their homes. You can boost during a cheap period and then coast during a peak period. The price reduction and the additional 2 hours off-peak launched on 1st July 2024 make this very attractive.
• Disadvantages?: As I don’t have a heat pump I am not sure. I think if you threw in an EV and home battery you’d have to stop and do some maths. A third-party compare app would be helpful to make sure you are on the best tariff during the winter.

Octopus Snug Tariff.

Octopus Snug is an Octopus Energy smart tariff designed for customers with storage heaters. It is a varibale time-0f-use tariff with 6 hours of off-peak electricrty at night with a one hour afternoon boost of off-peak too. The off-peak rate is 9p per kWh and can be used for the whole house.

• Ideal for: Anyone with storage heaters.
• Would I recommend the tariff? Yes, for the winter this is a great tariff. I may not stick with it year around as the day rate is slightly higher but if you can make use of the 7 hours of off-peak electricty at 9p per kWh it will really could bring down the unity price of your electricty. It is cheaper than economey 7.

Octopus Outgoing Tariffs

If you have green tech Octopus are leading the way with the smart and export tariffs. I have 16 solar panels. A 13.5 kWh battery and an EV. I have spent as many hours pondering tariffs as I have looking at my solar generation in the GivEnergy App.

Octopus are looking to build more fan club wind turbines. They have set up a page where landowners can get in touch – Winder. They say it’s just like Tinder but for people who love wind turbines.

Octopus Energy Tariffs Frequently Asked Questions.

Are there any additional benefits when you have a smart meter?

If you have a smart meter as well as having additional tariffs to choose you have three additional benefits;

• Octoplus – Octopus rewards. Free electricty sessions.
• Saving Sessions – earning money for using no energy or exporting energy at peak times during the winter.
• Power Ups – Get free energy at super green times. (South East England)

Here are some of the FAQs that might help you choose an Octopus Tariff. I have a separate section lower down the page for an overview of Octopus smart tariffs.

What is the Loyal Octopus 16-month fixed tariff?

The Loyal Octopus 16-month tariff is available to existing Octopus customers and is a fraction cheaper than the Octopus 16 months fixed tariff.

Can I switch Octopus tariffs if I find a better deal?

Yes, you can swap Octopus Energy tariffs very easily there are no exit fees on any of their tariffs. 

Are there any exit fees on any Octopus Energy tariffs? 

There are no exit fees on any of the Octopus Energy tariffs. You can switch tariffs at any time except;

• Tracker tariff – No exit fee but you may have to wait 2 weeks to switch to another tariff. You also can’t go back onto this tariff for 9 months. (To stop people gaming the system)
• Agile tariff – No exit fee, you can switch tariffs straight away but you can’t go back onto the tariff for 30 days. (To stop people gaming the system)

I have switched energy tariffs several times with Octopus and it is straightforward to do. Simply email hello@octopus.energy or DM them on Twitter plus you can call them too.

What can I do to lower my Octopus Energy bill?

Apart from using less energy if you use energy, you’ll get charged the set energy rate. By choosing an Octopus Economy 7 tariff, you can shift as much of your energy use as possible to the off-peak window, thereby lowering the average price you pay per kWh on your monthly bill.

Additionally, if you have a smart meter, you will have even more options. For example, by switching to Octopus Agile, you could even get paid to use energy!

Have Octopus Energy’s standing charges gone up?

Yes, in 2025 Octopus Energy increased its standing charges but they are still 4% below the rate set by Ofgem.

Standing charges are unfair. No matter how hard you try you can’t lower your standing charge. I live in South Wales which has a lower population density and just like Scotland, Wales and northern England we get hit with higher daily standing charges.

I appreciate the 4% reduction on the standing charge from Octopus, however, I wish there were a way for people with lower energy use to reduce it even further.

Perhaps we will hear more from Ofgem on this matter when they review the Energy Price Cap in the coming months.
