Is Octopus Energy cheap?

Yes, Octopus provides cheap green energy. If you’re not worried about your green credentials then you may be able to get cheaper tariffs but not by much.

If you are an electric car driver then Octopus offer a super cheap night-time charging rate of 5p/kWh between 12.30am and 4.30am. Octopus states that this is 25% cheaper than economy 7 night rates.

We feel Octopus provides a competitive rate, green credentials and great customer service which is why we personally use them.

Octopus Energy - renewable energy

All of the energy tariffs use 100% green electricity. Octopus promises that you won’t pay a premium for your tariff, unlike the competition who often bump up prices for adding a green tariff.

You can also carbon offset the gas you use if you want to minimise your environmental impact even further.

Octopus Energy is backed by their own investment are who boast about being the UK’s largest investor in solar power, responsible for nearly 40% of the nation’s large scale solar generation.

Octopus has some of the best green credentials we have seen. It is definitely a mission we can get on board with so much so that we have moved to Octopus for our own supply.

Just speak to friends and family about moving and use your own referral code found in your own account. This will save your friends £50 each and earn you £50 for each referral.

The thing that has made this successful in my personal life is using the service first before recommending it. My friends and family trust me with referrals because they know I have researched each company I recommend.

Please be aware that some people may be in a fixed tariff and so they may have fees to pay if they cancel or leave before the end of the contract. If this is the case then just set a future reminder and give them a nudge closer to the time.

Octopus Energy - great value green energy

We love Octopus Energy’s “green” credentials. The prices are not the lowest however they are competitive, particularly for green energy. They provide an ideal balance between choosing a cost-effective yet good for the planet energy supplier.

Where things get interesting with Octopus is their referral scheme. If you can get one of your friends or family to move using your referral code each year it makes the tariff one of the lowest. If you can help a few people switch using your code you are going to beat the best prices and deals on the market.

We both now use Octopus Energy and have not had any issues. The website is easy to use and spinning the wheel each month is a bit of fun, though we are yet to win big!
