OVO vs EDF (2024 Comparison)

Lasted Updated: 19th January 2024

If you’re trying to decide whether OVO or EDF is the better supplier for you, then you have come to the right place.

Here we compare the two suppliers across various categories, from customer reviews and price to customer service and complaints.

By the end of this article, you should have a better idea about which is the best energy supplier for you.

To start, here is a quick overview of each supplier:

Who are OVO Energy?

Back in 2009, OVO established itself and swiftly became a familiar name in countless homes. Now serving 1.5 million domestic energy customers across the country, OVO is one of the most popular energy companies in the U.K.

What makes them truly stand out is their unwavering dedication to green energy, presenting eco-friendly solutions at prices that are affordable. OVO takes great pride in making renewable energy the standard and ensuring that nuclear and coal have no place in its fuel mix.

Their impressive journey has been marked by winning a number of awards, including the USwitch Supplier of the Year award in both 2017 and 2019.

Who are EDF?

EDF, officially referred to as Électricité de France, stands as a leading multinational utility corporation, with its global headquarters situated in France.

It proudly maintains its position as one of the world’s top energy companies, actively involved in the generation, distribution, and supply of electricity and natural gas. EDF’s extensive operational reach spans multiple countries, making a significant impact throughout Europe, the United States, and various other regions worldwide.

Notably, EDF is widely acknowledged for its unwavering commitment to nuclear power, overseeing the operation of multiple nuclear power plants on a global scale.

What’s the difference in tariff options? 

In our first comparison, we’ll look at the different tariff options offered by both energy suppliers.


OVO offer a standard variable tariff, a fixed tariff for either 1 or 2 years and something which we haven’t seen often, a green ‘upgrade’ which can be added to their 1-year fix.

Below, we’ve listed the full details of their various tariff options: 

1 or 2-Year Fixed

  • Fixed unit rate plan for 12 or 24 months.
  • £75 exit fee per fuel if you choose to leave early.

1 Year Fixed + Greener Energy

  • Fixed unit rates for 12 months
  • 100% renewable electricity
  • 10% green gas and 90% carbon offset gas
  • £20 contribution to support new renewable generators
  • £75 exit fee per fuel

Simpler Energy

  • Standard variable tariff.
  • Flexible plan where prices can go up and down over time
  • No exit fees


EDF offers a similar standard rate tariff. Their fixed tariffs are slightly different, with the option of either 1 year or 3 years. You can see the full details below:

Standard Variable

– Rates can go up or down over time in line with Ofgem Price Cap
– No exit fees or end date
– Smart meter not required
– Does not claim 100% renewable electricity

EDF Essentials

– A fixed tariff with either a 1-year or 3-year term
– Exit fees of £150 per fuel for both tariffs
– Discount for paying by direct debit
– Smart meter required (available for free if you do not already have one)
– 100% renewable electricity
Summary: We feel that OVO deserves to win this round. Their fixed tariffs have lower exit fees and you also have the option of upgrading the one-year tariff to become ‘greener’. Their fixed tariffs also don’t require a smart meter like they do with EDF.

What’s the difference in price?

Next, we’ll look at the prices available for these tariffs. It’s worth noting that if you change any of our below criteria, you will likely get a different price, so please use these prices as a guide.

We used the following criteria when getting quotes for both OVO and EDF:

  • Dual fuel supply
  • Standard Meter
  • 2,900 kWh of electricity and 12,000 kWh of gas (Medium usage – 3-bedroom house occupied by a family of 4)
  • Postcode in the East Midlands

OVO gave us these prices for their available tariffs:

Tariff NameTariff DescriptionMonthly Cost
Simpler EnergyVariable tariff. Prices can either go up or down with no minimum term. No exit fees.£157
1-Year FixedA fixed-rate contract for 12 months. £75 exit fee per fuel.£167
2-Year FixedRates are locked in for 24 months. £95 exit fee per fuel.£167
1 Year Fixed + Greener EnergyFixed-rate for 1 year. £75 exit fee per fuel. Green addons.£175
Source. Non-direct debit or PAYG prices are not available online.

EDF gave us these prices for the tariffs they had available:

Tariff NameTariff DescriptionMonthly Cost
Standard VariableVariable rate tariff, no exit fees or end date.£157
EDF Essentials (3-year fix)3-year fixed tariff. £150 per fuel exit fees.£163
EDF Essentials (1-year fix)1-year fixed tariff. £150 per fuel exit fee.£164
These prices include a Direct Debit discount. The Standard Variable tariff is £168, both EDF Essentials tariffs are £172 without Direct Debit.

Summary: There is not much in it when it comes to price. EDF offers a cheaper price for both of their fixes, which would save you about £48 per year. However, if you decide to leave early, their exit fees are considerably higher. We’ll call this one a draw.

Who offers the greenest energy?

For many customers, how green their energy supplier is really matters. With more emphasis than ever placed on protecting the environment, we wanted to compare the efforts of EDF and OVO. 

EDF is really stepping up their game in the quest to become a more efficient and eco-friendly energy provider. They’re all about promoting and embracing low-carbon technologies that are great for our environment. EDF even goes the extra mile by offering electric vehicle leasing and providing solar panels to their valued customers. 

OVO is also all about taking care of our planet. Although they don’t have a specific green tariff right now, they do offer something called “Green Extra.” This lets you enjoy carbon-neutral energy, although it does come with a small extra monthly cost. They’re actively involved in lots of projects to offset carbon emissions across the UK and are committed to making a difference for a greener future. 

Summary: Both EDF and OVO are doing significant things to become greener than ever. We think it’s only fair that this round is a draw.

Who has better customer reviews?

Looking at current customer reviews is a great way to help get an understanding of how customers currently see that company. The best place for finding out this information is Trustpilot, as there is a huge volume of reviews to look at and there is some level of verification to check they are real.

Here is a comparison of OVO and EDF when it comes to customer reviews:

As you can see, EDF and OVO are rated exactly the same overall. With that said 69% of OVO’s ratings were 5 stars, whereas 73% of EDF’s ratings were 5 stars. Not much of a difference, but maybe EDF is slightly better at impressing customers.

In terms of response, both suppliers responded to 99% of their negative reviews.

Glancing over the reviews themselves, customers appreciate OVO’s turnaround time to fix issues such as boiler problems and EDF is commended for its engineers.

Summary: OVO and EDF are evenly matched when it comes to customer reviews. There is nothing to tell these two apart, so this round is also a draw.

Who has the better website and app?

We heavily rely on apps these days with millions of people using their phones to submit meter readings and check bill statements and energy usage. That’s why we think it is important to compare each supplier’s website and apps to see if one is better than the other.

Let’s begin with OVO who have an outstanding 4.8 out of 5 for their app as rated by customers. OVO’s app is praised for its practicality and smoothness. Customers know that they can log on and do what they need to do without wasting time.

OVO appear to have a solid Developer team for their app who seem to actively listen to feedback and fix bugs rapidly. This could be what makes their app so well-rated. We also can’t fault their website which is designed to be simple to navigate. Everything from page loading times to the process of logging in is made easy. 

The EDF app has a rating of 4.5/5 and is also highly recommended by its customers who seem to have few issues using it to manage their energy accounts with ease. Some customers have said that it can be tricky to find a customer service agent online via the app but the website also offers this functionality. Overall though, it seems to be getting plenty of positive feedback.

EDF also have a very well-designed website that ticks all of the boxes. From its minimalistic visual design to ease of use, EDF’s website is a modern, well-designed site.

Summary: Both suppliers have good websites and well-rated apps. OVO wins this round however for managing to maintain a better app review score.

Who has the better customer service?

Next, we’ll look closely at how the two energy names compare for customer service. This is an important area to consider as if you have any issues, you will be relying on customer service to help resolve them. Citizens Advice website is an excellent resource for looking at this, with quarterly updates that compare almost all active energy suppliers across a range of factors.

We have compared the two suppliers in these key areas:

Average call centre wait time00:58:0001:39
Emails responded to with 2 days97.3%62.30%
% customers with accurate bill98.7%95.50%
Switches completed < 15 days99.8%100.00%
Opening hoursMonday to Friday:
8 am – 6 pm
9 am – 8 pm (6 pm on Fridays)
9 am – 5 pm on Saturdays
Contact via PhoneYesYes
Contact via EmailYesYes
Contact via WebchatYesYes
Source: Citizens Advice
Summary: Both of these suppliers have reasonable call centre wait times, although EDF’s is over 40 seconds shorter. EDF responds to nearly all emails within 2 days, a much better rate than OVO. OVO does have slightly longer opening times, but EDF is the clear winner when it comes to customer service.

Who has fewer complaints?

Finally, we’ll look at what happens when things don’t go to plan and customers have to make a complaint. Energy suppliers have to publish this data publicly every quarter and we have looked at the last data below:

Complaints per 100k customers2,5471,489
Resolved per 100k customers2,335 1,213 
Resolved next working day57.68%83.3%
Resolved in 8 weeks91.53%96.8%
Sources: EDF Q2 2023. OVO Q2 2023.
Summary: OVO has fewer complaints and also generally resolves these complaints much faster. We feel OVO is the clear winner here.

What are the main differences between the two?

We have looked at a lot of information in this comparison between OVO and EDF. We’ve summarised everything below to help you decide which is the better supplier for you:

Tariff OptionsOVO offers a bit more to choose from when it comes to picking a tariff.OVO
PriceEDF is slightly cheaper for fixed-rate tariffs per month but has much higher exit fees.Draw
Greenest EnergyBoth energy names impressed us with their commitment to providing green energy. Draw
Customer ReviewsBoth OVO and EDF are doing well here and there is nothing to split the two.Draw
Website/AppEDF scores highly for its app and website but OVO has an almost 5-star review from its customers for its tech. OVO
Customer ServiceThe two energy suppliers both offer excellent customer service but EDF is doing that little bit extra.EDF
ComplaintsOVO received fewer complaints overall and also resolved them faster.OVO

Who is the better energy supplier?

This was a really close comparison as the two energy suppliers are almost as good as each other. However, we feel OVO just takes it as the better supplier. They offer better tariff options, have a better-rated app and perform better on complaints. EDF do perform better when it comes to customer service, however.

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.
