Octopus Energy Review (October 2026)

Octopus Energy review — October 2026: tariffs, customer reviews and service quality

Is Octopus Energy a good choice?

Our verdict

Octopus Energy is worth considering for helpful customer service, but smart-meter support and complex requests are the main reservations.

Octopus Energy may suit households that value helpful staff and straightforward contact. Its 4.8 out of 5 Trustpilot rating reflects mostly positive feedback, while Citizens Advice gives it 3.67 out of 5, ranked 5th. Customers frequently praise clear help with bills and accounts, although complex requests and installations can take longer to sort out. Smart-meter support is another reservation: the Which? supplier assessment gives smart meters 5 out of 10. For households wanting flexibility, Flexible Octopus is shown at £1,664 a year with no exit fee.

Who are Octopus Energy?

Octopus Energy puts buying renewable power and helping households change when they use energy at the centre of its approach. It buys renewable electricity from UK generators through long-term purchase agreements, alongside its role supplying household energy.[1]

There is also a wider generation business within the Octopus Energy Group. Octopus Energy Generation backs, builds and manages renewable projects. This work is distinct from the household supplier’s electricity supply: managing renewable projects and selling energy to homes are different parts of the energy market.[2]

Flexible Octopus is a standard variable tariff with the lowest annual estimate among the deals shown, at £1,664 a year. With no fixed term and a £0 exit fee, it may suit households that want to keep the option of switching again, although its rates can change. All estimates shown are for monthly Direct Debit.

Octopus 18M Fixed October 2026 v5 is an 18-month fixed deal at £1,831 a year, with a total dual-fuel £150 exit fee. It may suit households that want known rates and expect to stay for the full term. The rates are fixed, rather than the final bill, which still depends on energy use.

For a shorter commitment, Octopus 12M Fixed October 2026 v6 costs £1,886 a year over 12 months, with a total dual-fuel £100 exit fee. The trade-off is a £55 higher annual estimate than the named 18-month deal in return for a shorter term and an exit fee that is £50 lower.

Tariff details

Flexible Octopus is the standard variable choice. The fixed deals in the pricing data are Octopus 12M Fixed October 2026 v6, with a 12-month term, and Octopus 18M Fixed October 2026 v5, with an 18-month term. The shorter deal reduces the length of the commitment; the longer deal keeps fixed rates for longer. Both have an early exit fee.

Octopus Go suits drivers who want a set overnight charging window without vehicle or charger integration. Intelligent Octopus Go adds automatic scheduling, but needs a supported vehicle or charger connection and ongoing control permission.[1][2]

Tracker changes gas and electricity prices daily, while Agile changes electricity prices every half hour. Both carry wholesale-price risk. Tracker’s formula and standing charge stay fixed for 12 months, but its unit prices do not.[3]

Heating choices depend on the system in the home: Cosy accepts heat pumps and other supported electric heating, while Snug controls compatible storage heaters. For solar and batteries, Flux combines import and export periods but leaves battery scheduling to the household.[4][5][6]

Outgoing options separate export earnings from the electricity bought for the home. Agile Outgoing follows half-hourly wholesale prices, while Prime Outgoing is aimed at households able to move exports into the evening. Smart Export Guarantee also accepts eligible households whose electricity import tariff is with another supplier.[7][8]

Which?

Octopus Energy has a Trustpilot rating of 4.8 out of 5 from 880,701 reviews, with 90% giving five stars and 3% giving one star. Customers frequently praise helpful, polite staff who explain things clearly and provide prompt help with billing, tariff changes and account questions. Speaking directly to someone is a valued part of the service in this feedback.

When requests become more complex, some customers describe slow replies or unhelpful responses. Installation delays, communication problems and unresolved account changes also recur in feedback. Octopus replies to 97% of negative Trustpilot reviews, typically within one week, although a reply does not necessarily mean the issue has been resolved.

The Which? total score is 74%, combining customer feedback with a supplier assessment. Customers rate service, ease of contact and statement clarity at 4 out of 5 each, while value for money gets 3 out of 5. In the separate supplier assessment, complaints handling scores 8 out of 15 and smart meters 5 out of 10, pointing to reservations about both areas. Help for those who need it scores 10 out of 10 in that assessment.

Octopus Energy app reviews

Octopus Energy is rated 4.8 out of 5 on the App Store from 263,000 ratings and 4.3 out of 5 on Google Play from 47,449 ratings. Google Play also records 1,000,000+ installs, which is separate from the number of ratings. Both apps have been updated recently, including three iOS releases in the past 90 days.

iPhone users describe both useful features and frustrations with the usage charts. One user reported missing rate values and a missing colour split on an export chart. Another found the app useful for checking energy use throughout the day, but missed a feature that had displayed half-hourly details when sliding a finger over the chart bars.

Citizens Advice gives Octopus Energy 3.67 out of 5, ranked 5th, for April to June 2026. During that period, the average call centre wait time was 1 minute 9 seconds, while 86.4% of emails received a response within two days. These measures indicate how long an initial response may take, rather than how quickly a problem will be resolved.

Routine phone lines are open Monday to Thursday, 9am–5pm, and Friday, 9am–4pm, which may be awkward if you cannot call during the working day. Email support is available seven days a week, offering another way to get in touch outside those phone hours, though replies are not necessarily immediate.

For April to June 2026, 96.33% of smart-meter bills and 93.99% of traditional-meter bills were based on actual readings. Citizens Advice also reports that 91% of smart meters were working. Actual-reading bills reduce reliance on estimates, while the meter figure shows that automatic readings were not working for every smart meter.

Q2 2026

In Q2 2026, Octopus Energy reported 476 complaints per 100,000 customer accounts. This counts complaint events, rather than the number of individual customers affected, so it does not show the percentage of customers who had a problem.

For Q2 2026, Octopus reported resolving 43% of complaints on the same or next working day and 80% within eight weeks. These figures show how quickly complaints were closed, not whether customers were happy with the outcome. While some complaints were dealt with quickly, not all were resolved within eight weeks.

Citizens Advice recorded 21.4 complaints per 10,000 customers for April to June 2026. This covers complaints to advice bodies and the Energy Ombudsman, not complaints received directly by Octopus. It is a separate measure from the supplier’s own complaint rate and should not be directly compared with it.

Octopus also lists the following complaint reasons and actions it has taken or is taking. No reporting period or percentage shares were supplied for these themes, so they cannot be treated as a breakdown of Q2 2026 complaints.

Customer service
Response
Octopus says it has set up a staff training academy and grown its customer service teams. It is expanding training through monthly refresher courses and more opportunities for staff to become team experts.
General billing and meter readings
Response
Octopus says it has added clearer, customer-specific information to statement emails, expanded answers to common questions and tightened checks to prevent charges for energy used more than 12 months earlier. It is reviewing billing for products such as Intelligent Octopus and Fan Club, improving how customers submit meter readings and training staff to handle complex billing questions.
Smart meter billing and readings
Response
Octopus says it has made Smart Tariff bills clearer, set its system to retrieve missing energy-use data when bills are late and introduced regular staff training on smart tariff billing. It is working to improve automatic billing and the way it finds and fixes billing failures, alongside further staff training.
Payment issues
Response
Octopus says it has expanded its Octo Assist Fund, added an online financial support form and recruited in-house social workers. Customers can also view expected account balances. It says it regularly reviews Direct Debits and is working with other organisations to improve affordability checks and help customers find benefits. Support can include free electric blankets, standing charge holidays and reduced payments, depending on circumstances.
Smart meter installation and faults
Response
Octopus says it has replaced faulty smart meters, updated meter software and put automatic retry processes in place after unsuccessful installations. It reports moving to 4G communications hubs from Q4 2025 and testing Wi-Fi options. It is also giving customer service staff instructions to get meters working remotely and expanding its in-house installation team.

How green is Octopus Energy?

86%Renewable
Apr 2024–Mar 2025
Renewables86.4%
Nuclear13.6%
Other0%
Gas and Coal0%

Octopus buys renewable electricity from more than 700 UK generators through Power Purchase Agreements, or PPAs. These are contracts to buy generators’ electricity. Its annual supply mix also includes nuclear power, so renewable electricity and electricity from zero-carbon sources are not interchangeable descriptions.

For 1 April 2024 to 31 March 2025, the electricity Octopus Energy supplied came from renewables and nuclear, with no gas, coal or other sources recorded. This is an annual account of the supplier’s electricity supply, rather than a live reading of the power reaching a home.

Agile Octopus has a specific renewable-matching promise: each megawatt-hour used on that tariff is matched with a Renewable Energy Guarantee of Origin certificate from British renewable generation. These certificates record renewable generation; they do not mean a home receives only renewable power at every moment through the shared grid.

Octopus also describes owning wind turbines in Yorkshire and South Wales and adopting turbines in Lincolnshire and Yorkshire. Its Fan Club links nearby communities with discounts when the turbines are working hardest.

Separately, Octopus Energy Generation, part of the Octopus Energy Group, backs, builds and manages renewable projects. Its managed portfolio had 5.7 GW of capacity in May 2026. That wider investment activity is separate from the renewable matching promised on a named household tariff.

Our verdict on Octopus Energy

Octopus Energy is worth considering for helpful customer service, but smart-meter support and complex requests are the main reservations.

Octopus Energy may suit households that value clear help from staff and can use weekday phone support or email. Customers frequently praise its handling of everyday billing and account questions, and Which? customers give service 4 out of 5. Email availability seven days a week is useful if calling during working hours is difficult.

The picture is less reassuring for complicated requests and meter problems. Reviews describe delays with installations and account changes, while the Which? smart-meter assessment scores 5 out of 10. Households facing a difficult meter issue should weigh that alongside the positive service feedback.

For the energy contract itself, Flexible Octopus allows switching without an exit fee, but rates can change. The named fixed deals offer known rates in return for a commitment and an early exit fee. That choice is separate from whether Octopus's contact arrangements suit you.

Frequently asked questions

When can I phone Octopus Energy?

Routine phone lines are open Monday to Thursday, 9am–5pm, and Friday, 9am–4pm. Email support is available seven days a week.

How quickly does Octopus Energy answer calls and emails?

For April to June 2026, Citizens Advice reports an average call centre wait time of 1 minute 9 seconds. Octopus answered 86.4% of emails within two days. These are response measures, not times for resolving a problem.

Can I leave Flexible Octopus without an exit fee?

Yes. Flexible Octopus has a £0 exit fee and no fixed term. It is a standard variable tariff, so its rates can change.

What is the trade-off between the named 12-month and 18-month fixed deals?

Octopus 18M Fixed October 2026 v5 costs £1,831 a year over 18 months, with a total dual-fuel £150 exit fee. Octopus 12M Fixed October 2026 v6 costs £1,886 a year over 12 months, with a total dual-fuel £100 exit fee. The shorter deal has a higher annual estimate but a shorter commitment and lower exit fee.

Does Octopus Energy usually bill from actual meter readings?

For April to June 2026, 96.33% of smart-meter bills and 93.99% of traditional-meter bills were based on actual readings. These figures describe how bills were calculated, not the share of bills without errors.

What problems do customers report with the Octopus app?

One iPhone user reported missing rate values and a missing colour split on an export chart. Another praised checking energy use but missed a previous half-hourly chart detail feature. These are individual experiences; the overall App Store rating is 4.8 out of 5 from 263,000 ratings.

Does Octopus Energy reply to negative Trustpilot reviews?

Octopus replies to 97% of negative Trustpilot reviews, typically within one week. A public reply does not necessarily mean the underlying issue has been resolved.

Hi, I'm Rob, and I run Energy-Review.co.uk. I initially started this project in 2018 when I was looking to switch energy suppliers and found there wasn't a website that provided simple, data-backed reviews on all the suppliers available. Since then, I have spent a lot of time (too much, some may say!) looking at all publicly available data about each supplier and writing reviews using this information. These reviews are updated as regularly as possible, and any data is backed up by a source where necessary. I have also started writing guides on various energy-related topics, which hopefully you will find useful. If you find any issues, please use our contact form to let us know.
