Who is E.ON Next?
Essentially E.ON Next was E.ON’s answer when the energy market saw several new suppliers using technology and other resources in order to drive down prices.
E.ON Next was created in 2020 and took on previous Npower customers, which E.ON brought out in 2019.
Who are Octopus Energy?
Octopus Energy is an energy provider that supplies renewable energy. Established in 2016 and part of the wider Octopus Group of companies, they are the largest investor in the UK solar industry.
In addition, Octopus Energy also invests in wind generation, energy through the anaerobic digestion of plants, and rapid response gas generation.
Octopus now has over two million customers across the UK and has won several awards, including the Uswitch Supplier of the Year and the Which? Energy Supplier of the year 2021.
Octopus has also taken on customers from recently collapsed suppliers, including Bulb and Avro Energy.
What’s the difference in tariff options?
E.ON Next currently offers 1 variable tariff and 2 fixed tariffs:
– As the price can change, you are not locked into a contract and so are free to switch to a different tariff or supplier at any time.
– This tariff doesn’t appear to require a smart meter and also comes with a discount if you pay via direct debit.
Next Fixed 12m
– The cost of this security however is a £75 exit fee, per fuel. So £150 if you want to move away your gas and electrcity before the fixed term is up.
– This tariff also requires a smart meter to be already installed or for you to be happy to have one installed if not.
Next Fixed 24M
– Firstly, your contract is for 2 years
– Secondly, you are charged an exit fee of £150 per fuel. So £300 in total if you are are a duel fuel customer.
Currently, Octopus Energy is only offering two tariffs to new customers:
– Offers 100% renewable electricity
– No exit fees
Loyal Octopus 12M Fixed September 2023
– Exit fees of £75 per fuel
– Only available to existing customers
– No exit fees
– Only available with a smart meter
– Not available on signing up – see below for more details
– Unit rate is capped at 100p/kWh for electricity and 30p/kWh for gas (including VAT)
Octopus vs E.ON Next: What’s the difference in price?
We ran a like-for-like comparison directly on each supplier’s website to see what prices they offered for the tariffs mentioned above. We used the following details:
- Dual Fuel supply
- Standard Meter
- Medium usage (3-bedroom house with four occupants)
- 2,900 kWh of electricity and 12,000 kWh of gas
- Postcode in the East Midlands
It is important to note that your actual quote is likely to be different, as changing each aspect of the above criteria will result in a different amount quoted.
Let us look at how they compared:
On E.ON Next’s website, we were offered these prices:
|Tariff Name||Tariff Description||Monthly Cost|
|Next Flex||Flexible tariff where prices go up and down with the market. No contract.||£156.45|
|Next Fixed 12m V2||1 year, fixed contract. A smart meter is needed. £75 exit fee per fuel.||£166.47|
|Next Fixed 24M V1||2 year, fixed contract. A smart meter is needed. £75 exit fee per fuel.||£167.15|
We also looked at the Octopus Energy website to get a quote based on the same details above:
|Tariff Name||Tariff Description||Monthly Cost|
|Tracker Tariff||Smart tariff where prices change daily. No contract. No exit fees.*||£92.99|
|Flexible Octopus||Flexible tariff where prices go up and down with the market. No contract.||£155.47|
|Loyal Octopus 12M Fixed September 2023||12 month, fixed rate contract. £75 exit fee per fuel.**||£155.47|
The tracker tariff is only available to existing customers, but you can sign up on the flexible tariff above and then switch straight to the tracker. You can find out more in our Tracker Tariff article here.
Octopus wins on value for money.
Who offers the greenest energy?
Renewable energy and sustainability are at the heart of both of these suppliers’ offerings.
Let’s take a look to see how they compare in this area:
E.ON next advertise heavily that 100% of the electricity they generate is from renewable sources. This means that the electricity their customers use is sourced from; Their own renewable energy generation plants, supply agreements with independent renewable energy wind and solar plants and purchase renewable electricity certificates.
On their website E.ON Next states, that they generate enough electricity at their biomass plant to supply 100,000 homes across the UK. While green gas is not mentioned at all on the one tariff on offer, we understand that E.ON Next has invested in green gas certificates for their greenest tariffs (not currently on offer).
Just like E.ON Next, Octopus put their green energy credentials at the forefront of its offering. They offer 100% renewable electricity on all tariffs as standard. Much of this they generate at their own plants, and they invest heavily in the production of renewable electricity and green gas from biomass plants.
Octopus’s Supergreen customers also receive a carbon-neutral gas supply which is offset by Octopus’s partnership with Renewable World.
Octopus vs E.ON Next: Who has better customer reviews?
Trustpilot is the most reliable website to compare 1,000’s of genuine customer reviews. Here is our comparison based on the information available:
- E.ON Next scored 4.2 out of 5 based on over 59,000 reviews (source)
- Octopus scored 4.8 out of 5 based on over 180,000 reviews (source)
We have to assume the low number of E.ON Next reviews is due to them only being around since 2020 as there is a significant difference.
Overall, 73% of E.ON Next customers rate them as ‘Excellent’. At the other end of the scale, 15% rated them as bad, and the additional 13% fell somewhere in between.
In the case of Octopus, 89% of their customers rate them as excellent, and just 3% rated them as bad. Leaving just 8% of customers somewhere between.
Both companies respond to customer reviews, both good and bad.
Both companies receive a high number of positive reviews. However, in the case of E.ON Next, when customers feel let down is the time it takes to answer the phone. Some customers state they have had to resort to messaging on Twitter to get a reply. It’s also clear that their customer service agents are a credit to them, with many of them being personally thanked on Trustpilot.
Similarly, Octopus customers more often state that the agent they spoke to was helpful and resolved their queries. There are also comments about switching is easy and that they are always clear and efficient when it comes to communications.
Who has the better website and app?
We tried out both E.ON Next and Octopus’s websites. Both are really well laid out, and we had no trouble finding our way around. It’s possible to view tariffs, bills, input meter readings and update any personal details.
You can download apps for both E.ON Next and Octopus Energy onto a smartphone or tablet. These apps have been designed for easy account management where you can check your usage, bills and tariffs.
In Octopus’s case, over 71,000 customers rank their app well at 4.8 out of 5 stars. Mainly due to the functionality and reliability of the app.
The E.ON Next App is similarly popular and is also rated 4.8 out of 5, proving that they too have developed a well-functioning and user-friendly app.
Who has the better customer service?
We checked data on the Citizens Advice website to compare information on the customer service offered by each supplier. We believe they offer the most unbiased view based purely on facts obtained from Ofgem and the suppliers directly.
Please note in this case, E.ON Next are not listed separately from E.ON, so we have used E.ON’s stats here for comparison:
|Average call centre wait time||03:44||02:15|
|Emails responded to with 2 days||56.8%||75.9%|
|% customers with an accurate bill||97.8%||96.2%|
|Switches completed < 15 days||98.1%||97.7%|
|Opening hours||9 am – 5 pm (4 pm Friday)||8 am – 8 pm (8 am – 6 pm Saturday)|
|Contact via Phone||Yes||Yes|
|Contact via Email||Yes||Yes|
|Contact via Webchat||No||Yes|
Due to being better in the two key areas, E.ON Next wins on customer service.
Which supplier has fewer complaints?
We looked at the complaint data each energy provider openly provides. To make sure we cover the same period for both, we will look at Q4 for 2022.
We have summarised the data in the below table:
|Octopus Energy||E.ON Next|
|Complaints per 100,000 customers||1,126||1,885|
|Resolved next working day||71%||71%|
|Resolved in 8 weeks||90%||91.4%|
Octopus wins when it comes to complaints.
What are the main differences between the two?
