Who are EDF Energy?

EDF Energy has been supplying energy to the UK market since 2002. They are owned by French company Électricité de France, abbreviated to EDF for the UK market. EDF’s offices are based in London, and they supply over 5.7 million homes. Considering its large size, EDF has a relatively low number of customer complaints.

EDF are not just about energy either. They supply various smart home products, including electric vehicles, charging points, and boiler insurance.

Who are Octopus Energy?

Octopus Energy is part of the wider Octopus Group, established in 2000. They deal in the energy market and the investment management sector. Octopus Energy started supplying the UK energy market in 2015. Since entering the market, they have gained an impressive 6.5 million customers.

Octopus focus on supplying green energy, and they generate their own green electricity and gas. 100% of the energy they supply into the UK comes from renewable resources. This is produced using a combination of anaerobic digestion, wind, solar, and sea power.

Octopus has achieved several prestigious awards within the energy market for its competitive tariffs and excellent customer service record. Including the Uswitch supplier of the year and the Which? Energy supplier of the year.

Octopus vs EDF: What’s the difference in price?

We ran a price check on both suppliers using the following criteria to see how they measure up:

  • 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

Let us look at how they compared and see if Octopus is cheaper than EDF or vice versa:

EDF Energy

Tariff NameTariff DescriptionMonthly Cost
EDF Essentials MarFixed tariff for one or two years. £125 per fuel exit fees.£142.88
Standard VariableFlexible tariff where prices go up and down with the market. No contract.£142.92


We used the same parameters to obtain a quotation from Octopus Energy. We were offered a choice of three tariffs:

Tariff NameTariff DescriptionMonthly Cost
Tracker TariffSmart tariff where prices change daily. No contract. No exit fees.*£92.99
Flexible OctopusFlexible tariff where prices go up and down with the market. No contract.£141.67
Octopus 12M Fixed12-month, fixed rate contract. No exit fees.£138.61
*Using an average rate over previous months for both fuels. Only available to existing customers. Source.
Conclusion: Is Octopus Energy cheaper than EDF? Yes, Octopus is the winner of the best value tariff, with Octopus Fixed coming out slightly cheaper per month than the EDF Essentials tariff.

The Octopus tariff also has no exit fees.

Octopus Energy is the winner when it comes to price comparison.

What’s the difference in tariff options?


EDF Energy offered us two tariffs at the time of the quote:

Standard Variable

– This is a variable rate tariff

– No exit fees

EDF Essentials

– This is a 12 or 24-month contract with unit prices and standing charges fixed for that time
– £125 per fuel exit fees
– Smart meter is required


Octopus Energy is offering three tariffs at this time:

Flexible Octopus

– This is a variable rate tariff
– Offers 100% renewable electricity
– No exit fees

Octopus 12M Fixed

– This is a 12-month contract with unit prices and standing charges fixed for that time
– No exit fees
– 100% renewable electricity

Tracker Tariff

– Unit rates change daily
– 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)
Conclusion: Both suppliers offer fixed and variable tariffs. EDF offers the option of fixing for two years whereas Octopus have the option of an innovative smart tariff.

The biggest differences come with Octopus offering 100% renewable electricity on all their tariffs, no exit fees on their fixed tariff, and they do not require you to have a smart meter either.

Due to Octopus offering the better options, they win this round when it comes to tariffs.

Who offers the greenest energy?

As we become more environmentally conscious and aware of the benefits of switching to renewable energy sources, we want to know if our energy supplier is taking steps to make energy more sustainable and what they are doing to move away from fossil fuels.

Here we look at where both of these suppliers stand when it comes to green energy:


EDF is one of the largest investors in renewable energy. They are Britain’s biggest generator of zero-carbon electricity and meet around one-fifth of the countries demand for renewable electricity. Unfortunately, at this time, EDF does not have a green gas offering for comparison.


Octopus Energy put a large number of resources into generating green energy. 100% of the electricity they generate is from renewable sources. This is standard on both tariffs currently on offer. If you choose Octopus’s Supergreen tariff, your carbon use is also fully offset.

An impressive 40% of the solar power generated across the UK comes from Octopus investments. As a company, Octopus plays a significant role in implementing and developing new renewable energy solutions to replace fossil fuels.

Conclusion: Both energy suppliers are undoubtedly doing their bit to support green energy. However, with their green initiatives and offsetting of green gas, Octopus comes out slightly ahead when it comes to the greenest supplier—it is a close one, though!

Octopus or EDF: Who has better customer reviews?

We consulted Trustpilot to see how EDF and Octopus’s customers rate their customer service. Both companies have 10,000s of genuine customer reviews.

Here is what we found:

Both suppliers ask their customers to review their good and bad service. Both suppliers appear to take the time to respond promptly to negative reviews.

From reading some of the reviews, it seems in both cases; their customers are generally pretty happy. However, we have noted that considering their size, EDF energy has a considerably lower number of reviews than Octopus. We are not sure of the reason for this.

Octopus Energy customers frequently praise the quick and efficient service they have received. EDF customers praise the chat and text functions available to them, while a few customers complained about long wait times to get through to customer services or the time taken to resolve problems.

Conclusion: Both suppliers have received many positive Trustpilot reviews. And on the surface, there isn’t much to choose between the two. However, based on ratings and the sheer number of reviews received, we have to give this one to Octopus again.

Who has the better website and app?

Both EDF and Octopus have easy-to-use and functional websites. Once you sign up with them, you can manage your energy account and tariff. It’s simple to find their contact information and corporate information. We had no trouble finding everything we needed quickly on either website.

Both EDF and Octopus Energy also offer an app that customers can download onto their smartphone.

In Octopus’s case, customers rank their app at 4.8 out of 5 on the Apple App Store. Reviews show customers are happy with the control they have over their account through the app, which lets them pay bills, give meter readings, and see up-to-date usage.

EDF’s app seems to fair almost just as well, with an app store score of 4.5 out of 5, showing that they have developed a functional and user-friendly app too.

Conclusion: Both energy suppliers offer good online account management through a browser. When it comes to apps, they also both provide something that customers are happy with. Octopus wins here, though, due to the slightly better reviews.

Who has the better customer service?

CitizensAdvice offers a neutral and unbiased comparison of energy suppliers’ customer service. We checked the website to see how EDF and Octopus did in critical areas that matter to their customers.

This table gives a summary of how both suppliers compare with the latest data (from July to September 2023):

Average call centre wait time04:5002:12
Emails responded to with 2 days66.1%96.9%
Fewer complaints received2 out of 51 out of 5
Contact waiting time2 out of 54 out of 5
Customer commitments5 out of 55 out of 5
Opening hours9 am – 5 pm (4 pm on Fridays)8 am – 8 pm
Source: Citizens Advice

Octopus Energy answers the phone on average 2 minutes and 38 seconds slower than EDF. You are also much more likely to receive an email reply from EDF within two days than from Octopus.

Both companies have regular opening hours; however, EDF’s customers can call outside of regular business hours which could be a big plus for those that can’t call during the working day.

Conclusion: EDF is the clear winner here. They come out ahead of Octopus in every single category.

Who 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 table below:

Octopus EnergyEDF
Complaints per 100,000 customers1,0422,295
Resolved next working day64%58%
Resolved in 8 weeks84%92%
Sources: Octopus Energy Q4 2023. EDF Energy Complaints Q4 2023.
Conclusion: The stats clearly show that Octopus Energy received far fewer complaints than EDF.

When it comes to complaint resolution time, there isn’t much at all between the two suppliers.

It’s a close one, but Octopus is the winner here due to having fewer complaints.

Octopus vs EDF: What are the main differences between the two?

These two suppliers are pretty well known across the UK energy market. EDF is one of the six big energy suppliers with over five million customers. Octopus has been around for just five years but has made a name for itself by offering energy tariffs that are fair and green.

Both are significant investors in the production of green energy. Both have a relatively good record and are rated well by their customers regarding customer service.

Hi, I'm Rob and I run Energy-Review.co.uk. I initially started this project 5 years ago 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 spent have 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.
