Octopus Energy Review Summary
Who are Octopus Energy?
Octopus Energy was founded by Greg Jackson in 2015 with a simple aim: to make energy better. In just a few years, they have grown rapidly and are now the UK’s largest energy supplier. As of February 2025, they serve 7.3 million households, nearly a quarter of the market! Their growth is partly thanks to winning over customers from other suppliers such as Avro Energy and Shell Energy.
I was particularly impressed by their reputation. Octopus Energy is known for excellent customer service, fair prices, and a strong focus on innovation. They have received awards like the Global Good Company of the Year 2024 and have been a Which? Recommended Provider for eight years in a row. It’s clear that their commitment to service and green energy really makes a difference.
Octopus Energy Review: Is Octopus a good energy supplier?
From what I’ve seen, and from the experiences shared by many other customers, Octopus Energy is a great provider. They focus on renewable energy, offer competitive pricing, and keep customer satisfaction at the forefront. Their green energy tariffs and smart technology solutions are designed to reduce your carbon footprint while keeping bills low.
Reviews say it all. On TrustPilot, Octopus Energy scores an impressive 4.8 out of 5 stars from over 510,000 reviews, with 90% of customers rating them as excellent. This makes them one of the best-rated suppliers among the big players.
| Rating | Percentage of reviews |
|---|---|
| Excellent | 90% |
| Great | 5% |
| Average | 1% |
| Poor | <1% |
| Bad | 3% |
And each year, Which? surveys customers. In 2025, Octopus Energy came top of 18 suppliers with an overall score of 74%.
They also won the uSwitch ‘Energy Supplier of the Year’ award for the fifth time, based on more than 17,000 responses. These figures really backed up what many of us have heard from friends and family.

What is Octopus Energy’s customer service like?
I know how important it is to have friendly and efficient customer service. Octopus Energy runs UK-based call centres that are open Monday to Thursday from 9 am to 5 pm, and on Friday until 4 pm. This might be a bit inconvenient if you’re working a 9-to-5 job, but the good news is you can always email them any day of the week.
According to Which?, customers rate their service a perfect 5 out of 5. They are among the fastest to answer the phone, typically in just over 2 minutes (some sources even say 2 minutes and 28 seconds). Emails usually get a reply within two days. I found that these quick and friendly responses really set them apart.
When it comes to emails, CitizensAdvice have found that Octopus respond to just over 79.9% of emails within 2 days.
By looking at many of the Octopus Energy reviews on TrustPilot, you can also see generally customers’ experiences match up with these stats, with most customers praising Octopus’ Customer Service speed and level of response.
What energy tariffs do Octopus Energy offer?
Octopus Energy offers a range of energy tariffs, they have traditional tariffs available alongside a whole host of newer, more innovative tariffs.
If you are looking for a more traditional tariff, then Octopus currently have two available for new customers:
- Octopus 12-month fixed: This is a 12-month fixed rate tariff (currently only available for existing customers). It comes with 100% renewable electricity and no exit fees.
- Flexible Octopus: This is a variable rate tariff with 100% green electricity. No exit fees but the unit price could change over time.
These two tariffs are similar to what you would find with most suppliers, but it is important to note however that you get renewable electricity with both. Something that many other suppliers don’t offer as standard.
Alongside these more traditional tariffs, Octopus has some more innovative tariffs available too:
- Outgoing Octopus
- Octopus Go
- Agile Octopus
- Octopus Tracker
Like most domestic energy suppliers, Octopus do not currently offer a zero-standing charge energy tariff. They are, however, one of the most competitive when it comes to standing charges. You can see how they compare in our zero-standing charges guide.
Are Octopus Energy cheap?
From my research, Octopus Energy is generally affordable. They use smart technology to cut costs and rely on renewable energy, which helps them offer lower prices compared to many traditional providers. Energy prices do change, but overall, they are one of the more budget-friendly options among the larger companies.
We have a whole post dedicated to comparing suppliers with British Gas, which will help you find out if Octopus is cheaper than British Gas.
Octopus prices per kWh (unit rate) plus standing charge
To give you an idea of the price you could be paying per kWh and for a standing charge, the rates for their cheapest fixed and cheapest variable tariffs, for both gas and electricity, are below:
Gas
| Tariff Name | Tariff Type | Price per kWh | Standing Charge |
|---|---|---|---|
| Octopus 12M Fixed | Fixed | 6.23p | 29.43p |
| Flexible Octopus | Variable | 6.19p | 29.43p |
Electricity
| Tariff Name | Tariff Type | Price per kWh | Standing Charge |
|---|---|---|---|
| Octopus 12M Fixed | Fixed | 24.26p | 54.85p |
| Flexible Octopus | Variable | 24.12p | 54.85p |
If you are willing to switch to a non-traditional tariff, then the Octopus Tracker tariff is generally considered to be the cheapest tariff available from any supplier. You can find our latest comparison of the cheapest gas and electricity tariffs here.
Octopus does offer some perks as well, which can help reduce the cost of your bill. They have a new reward scheme called ‘Octoplus’, which effectively rewards you for saving energy, referring friends to join them, or spinning their ‘Wheel of Fortune’. We have written a whole post on Octoplus if you would like to find out more.
One way you are rewarded through Octoplus is through their ‘Saving Sessions’. These are normally one-hour periods when you can get money credited back to your bill for each unit of energy you save. You can find out more about Saving Sessions here.
If you are joining Octopus Energy for the first time, you should also consider that you can get £50 referral credit. This can make a significant difference when comparing prices across suppliers over the year.
Even if they aren’t the cheapest on a comparison site, when you factor in referral credit and the money you can save through their extra incentives, they may work out cheaper overall.

How green is Octopus Energy?
For those who care about the environment, Octopus Energy is a standout choice. Octopus are one of our top green energy suppliers.
All their tariffs come with 100% renewable electricity. While many other providers may charge extra for green energy or only offer it on certain plans, Octopus includes it as standard.
Even more impressive, they generate renewable energy themselves. Through their subsidiary, Octopus Renewables, they are one of Europe’s largest investors in green energy. With over 200 solar farms, along with significant wind and anaerobic digestion projects, they truly walk the talk when it comes to sustainability.
You can see where there energy comes from below:
| Fuel source | % of supply |
|---|---|
| Natural Gas | 0% |
| Nuclear | 15.2% |
| Renewables | 84.8% |
| Coal | 0% |
| Other Fuels | 0% |
Do they receive many complaints?
All energy suppliers have to publicly display their complaints data every quarter. Below we have displayed the key complaints data for Octopus:
| Complaints per 100k customers | 1,598 |
| Resolved per 100k customers | 1,546 |
| Resolved by next working day | 71% |
| Resolved in 8 weeks | 87% |
Every energy supplier faces some complaints. With Octopus Energy, the most common issues relate to payment and billing, and occasionally, customer service. However, they are very open about these challenges and work hard to fix any problems.
Most complaints are resolved quickly, and detailed performance reports are available for those interested in the progress being made.
How good is the Octopus app?
Octopus have apps available in both the iOS app store and the Google Play store.
The app is very popular with customers and, across both platforms, has very positive reviews. The iPhone app scores 4.8/5 from over 145,000 reviews, and the Android app is rated 4.7/5 from over 35,000+ reviews.
I found the Octopus app to be very user-friendly. Available for both iOS and Android, it allows you to manage your account, pay bills, check your energy usage, and even add meter readings if you don’t have a smart meter. The app also alerts you about upcoming Saving Sessions and shows you how much energy you’ve saved.

I recently switched to Octopus Energy and was pleasantly surprised by the £50 credit offer. As an energy-conscious consumer, I appreciate the transparency and competition in the renewable energy market. Thanks for sharing this review – it’s helpful in making informed choices.
Great review! I’m considering switching to Octopus Energy and this post has given me the confidence to do so. The £50 credit offer is a great incentive. Will definitely sign up now!
Why can’t the power company’s give a price per Kilowatt.Not monthly guess estimate Philip
Hi,
I’ve recently signed up to Octopus, and immediately received £50 credit as did my friend for the referral. I then quickly swapped to the Agile tariff for electricity and Tracker for gas. All of this went very smoothly. I’d very recently moved to a smaller property and they calculated my usage. I chose to increase this to pay a bit more with the winter months coming and not having any credit built up. Again this was easy to do.
I downloaded the Octopus App and can see how much I am going to pay the following day Peru it every half hour. I have already saved about £20 last month ( October) it’s made me use the washing machine, tumble drier and dishwasher at different times.
As a retired person at home during the day I’ve found it easy to use most if my appliances during much cheaper times of the day. However it will be interesting to see how high the electricity goes for peak times like Christmas Day, and whether it then remains a cheaper option for me.
Iam very happy with octopus ! The only this I don’t like is having to read. My gas and electric meters every month. I am 77 and had both knees replaced and two collapsed vertebrae’s my electric meter is in a cupboard but I need to use steps to take readings as it is so high. The gas meter is outside but is so low to the ground I’m struggling to take readings .I have a British Gas smart meter but apparently is not compatible with octopus company !
I am very disappointed with Octopus Energy. My contact needed to be renewed. They upped my energy rate then a couple of months later, did it again. They recommended the package that I accepted in good faith. I have friends who have joined Octopus energy. Yet they still have raised my rate twice in a few months. I am very very disappointed with them. Be careful with the package to accept from them.
My Concern like many others is the current effect of gas prices and how they will impact on green gas.
Dear Sir/Madam,
I came to this site in the hope and expectation of seeing actual cost figures for i) £s/kWhr import ii) £s/day for standing charge iii) £s/kWhr for export.
Please, I beg you, where can I find these figures?
Yours sincerely,
E.H.Baldock
Having been with octopus energy for a year, I have had no problems
transferring over to them, or dealing with them regarding our bill, always
tell us when our d/d is being taken out, always e-mail when our meter reading is needed.
So far very pleased with their service.
I have received nothing but bad service and have been left with a large bill and smart meters that don’t work. When I have asked for help from octopus energy I was offered help and then left with nothing. I have been over charged and they seem to think if they don’t fix the meters I will not be able to prove they are over charging me. They are about as much help as a chocolate tea pot.
Octopus Energy’s very poor estimates of household energy consumption have left us in debit by almost half the original tariff, after a period of 2.5 years. It’s not acceptable to quote other companies out of customers and then not deliver on these estimates. Very bad experience.
What is tier unit price rate .electric only?

I recently signed up to Octopus Energy. My son gave me a referral code and we both have received £50.00 credit. So it works!
I signed up because of his experience with Octopus, which has been very positive:
Great customer relations
One of the lowest tariffs for my postcode
Renewable energy
£50.00 referral code system
No exit fees
Smooth transition from my previous supplier
The online web site is very user friendly and if you need to phone I have found an agent was available quite quickly
