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

We requested an online quote from both suppliers based on the following parameters:

  • Dual fuel supply
  • Standard Meter
  • Medium usage (3 bedroom house occupied by a family of 4)
  • 2900 kWh of electricity and 12000 kWh for gas
  • Postcode in the South East of England

Let’s compare the results:

Ovo offered us just three tariffs to choose from:

  • Better Energy – fixed unit costs for 12 months £90 per month
  • Two years fixed – Lock in your rates for 24 months for £92 per month
  • Simpler Energy – Ovo’s standard variable tariff where prices can go up or now with no minimum term costing an estimated £95 per month.

All of OVO’s tariffs offer 100% electricity from renewable sources. They also plant a tree in your name every year you stay with them.

OVO’s fixed tariffs have an early exit fee of £60 should you choose to leave them early. There is no exit fee for the Simpler energy tariff.

We ran the same quote details through Octopus Energy. Their top recommendation for us was the Octopus Tracker at a competitive £70.19 per month.

Octopus also gave us three other options to choose from:

  • Super Green Octopus – Octopus’s greenest tariff where any gas use is offset through Octopus’s partner renewable world and, of course, 100% renewable electricity supply for £94.64 per month.
  • Octopus 24M fixed – This tariff allows you to lock in your unit costs for 24 months at £94.22 per month.
  • Flexible Octopus – This is Octopus’s standard variable tariff, and the monthly cost quoted was £90.11
Conclusion: There isn’t much to choose between the two suppliers three standard tariff options, but the Octopus Tracker pricing blows the rest out of the water by being a significant £20 a month cheaper.

This innovative tariff has won Octopus the points for price comparison!

OVO vs Octopus: What’s the difference in tariff options?

Both Octopus and OVO appear to offer three “standard” tariff options.

Octopus goes a little further by providing three additional innovative tariffs which may suit some customers, let take a look at the options from both suppliers:


OVO offers three tariffs, two fixed-term options and one variable. All tariffs include 100% renewable electricity as standard. They will also plant a tree in your name each year you renew with them. The different tariffs on offer are as follows:

Better Energy

  • Fixed unit rate plan for 12 months.
  • 100% renewable electricity
  • Tree planted in conjunction with Ovo’s partnership with the woodland trust.
  • 3-5% interest rewards
  • £60 exit fee if you choose to leave early

2 Year Fixed

  • As above, your unit price will be fixed for 24 months.

Simpler Energy

  • Standard variable tariff.
  • Flexible plan where prices can go up and down
  • No exit fees
  • 100% renewable electricity as standard
  • Tree planted in conjunction with OVO’s partnership with the woodland trust.
  • 3-5% interest rewards

With all the tariffs, you can also sign up for OVO beyond. OVO, describe this as a green upgrade that cuts carbon, plants trees and protects rainforests. What this means for you is:

  • Your energy supply is 100% carbon neutral.
  • Five extra trees planted each year for schools and communities.
  • Protect natural habitats around the world with our carbon-offsetting projects
  • It helps fund eight tiny forests to bring nature to kids.

You can add OVO beyond to any tariff for free for the first three months, then £6 per month after that.


Octopus offers three standard tariffs which are comparable to OVO. However in addition, they offer three other innovative tariffs for customers who might want something a little different:

Octopus Super Green Tariff

This is Octopus’s greenest tariff, fixed for 24 months with no exit fees. 100% of the electricity supply comes from renewable sources, and your gas use is carbon offset through Octopus’s partner renewable world.

Octopus 24 months fixed

This tariff fixes your standing rates and unit costs for 24 months. This tariff is ideal for customers who want to lock in their pricing for a fixed period. There are no exit fees should you wish to change supplier or tariff early.

Octopus tracker

The most transparent tariff available in the UK. Energy prices are updated daily in line with wholesale market prices. With this option, Octopus customers know they are getting the best possible price for their energy.

In addition, the tracker gives customers daily updates on their energy supply and 12-month forecast. You also get a breakdown of where your money is going. As with other tariffs, there are no exit fees.

Flexible Octopus

This is Octopus’s standard variable tariff offering. The unit rates on this tariff can rise and fall with wholesale prices. However, you’ll always get 30 days notice from Octopus should there be a price increase coming, giving you enough time to look at alternatives.

Agile Octopus

Octopus’s “plunge price tariff” means that customers get paid when more energy is produced by renewable sources than is consumed in the UK.

Octopus go

This tariff offers lower electricity rates at night between the hours of 00:30 and 04:00. According to Octopus, this tariff works out around 50% cheaper than Economy 7 tariffs. Octopus markets this as ideal for those users of electric vehicles who typically charge their cars overnight.

Conclusion: Both OVO and Octopus offer a range of tariffs to suit different customer needs. They are both impressively green. Octopus has the edge in this area for a couple of reasons, they do not charge exit fees on any tariff, and they offer a greater range of innovative tariffs.

Our winner when it comes to Tariff options: Octopus!

Octopus vs OVO: Who offers the greenest energy?

Both of these suppliers are some of the greenest out there. Both offer renewable electricity as standard on all tariffs.

Octopus has a green tariff called super green Octopus. With this, your carbon use is also offset to make your home’s energy completely carbon neutral.

Octopus’s subsidiary Octopus Investments is responsible for supplying 40% of the solar power generated in the UK and play a significant role in developing renewable energy solutions.

OVO also has a big focus on green initiatives. Although they don’t offer an exclusively green tariff, you can add their green extra to make your energy carbon neutral for a monthly fee. They also plant trees for every year you stay with them and are involved in several carbon offsetting projects.

Conclusion: Both of these suppliers green efforts leave the competition standing when it comes to reducing our carbon footprint on the planet. For this category, it’s a tie. They are both green heroes of the energy supplier market!

Octopus vs OVO: Who has better customer reviews?

We checked out both suppliers on Trustpilot to see how 10,000’s of genuine customers rated their service.

Here are their scores as of June 2021:

  • OVO scores 4.3 out of 5 based on over 46,000 reviews
  • Octopus score 4.7 out of 5 based on over 58,000 reviews

90% of those customers who left a review for Octopus rated them excellent compared to 70% for OVO.

Both companies actively ask their customers to leave reviews to capture both the positive and negative.

Octopus has replied to 83% of their negative reviews, whereas OVO have responded to 99%

Most reviews on the first page are positive for both companies.

When customers do have issues in both cases, smart meter installation seems to be an issue for both suppliers and pricing errors appear to be a more common complaint for OVO customers.

However, both have a high star rating, which shows that they are doing well on the customer review side of business!

Conclusion: Due to receiving a higher star rating and 90% of their reviewing customers rating them as excellent – Octopus win when it comes to customer service reviews.

Octopus vs OVO: Who has the better website and app?

Both suppliers have an app available for their customers to manage their account from their mobile devices. In theory, this is a great way for customers to access their account at the touch of a button.

Both apps are designed to allow customers to update their details, view tariffs, submit meter readings and view their usage. But how do the two suppliers apps compare?

OVO’s app has rated 4.5 stars out of 5 on the app store, which is no easy feat! They have created a functional, easy to use App for their customers that improves the customer experience.

In comparison, Octopus is lagging when it comes to their app. Scoring just 1.6 out of 5, the app is reported to be slow and hard to use because of the poor functionality.

Most customers say they give up using it, and it’s simpler to log into the website when they need to manage their account.

Both suppliers have websites that function well on a desktop and mobile device. They are easy to use and navigate. We didn’t struggle with either to find what was needed.

Conclusion: OVO wins when it comes to the best app. They have managed to create something that their customers are delighted with!
