A bit about Octopus Energy and its energy

Octopus Energy is one of the best energy suppliers in the UK. The company entered the energy market to be the supplier that saves you money and the planet’s precious resources, and it’s turned a lot of heads. Octopus Energy serves 2.2 million domestic customers, meaning the energy supplier has a 7.5% market share. Their wider group supplies Affect Energy, Ebico Living, London Power and Co-Op Energy means Octopus Energy supplies 4.9 million domestic customers.

There are no contracts with Octopus, just pure and simple billing, great customer service and green energy tariffs as standard, made possible by the backing of Octopus Investments, the UK’s largest investor in solar power. The focus on green energy extends beyond their own concerns too, helping brands such as Arsenal FC and Marks and Spencer join the fight in the name of renewable energy generation. 

What’s Octopus Energy’s renewable energy generation like?

In terms of renewable electricity, you won’t find much better than Octopus Energy. In fact, the Renewable Energy Association gave Octopus Energy the 2019 award for ‘the company that’s done the most to advance UK renewables’, which is quite an impressive title to achieve. 

Octopus Energy strives to make the entire green energy industry as transparent as possible, so as to not confuse consumers into thinking they’re receiving planet-friendly energy from an electricity grid that doesn’t exist. So, Octopus Energy replaces each and every non-renewable electron used by its customers through various renewable energy generation investments, sending green electrons straight back into the grid. 

They’re not just in it for themselves but for the greater good of the planet. Octopus Energy supports numerous different projects that also strive towards a greener planet via renewable energy generation, teaming up with over 93 small-scale solar, wind and hydroenergy generators across the UK. 

Paving the way for others behind them, Octopus Energy were also the first UK energy supplier to offer a smart export tariff, which paid people for generating a surplus amount of their own renewable energy. Now having launched a similar endeavour, Panel Power, they’ve also become the first British energy supplier to offer a business energy export tariff. 

What payment methods does Octopus Energy offer?

The main method of energy payment with Octopus Energy is monthly Direct Debit, as it’s the payment method that offers the least hassle. However, they are willing to accept others if it is more convenient for them. 


You can also choose to pay using:

  • A bank transfer
  • A cheque
  • A credit card/debit card
  • Cash via a PayPoint location


In order to change the payment method, just contact Octopus and they will help make the necessary changes for you. 

Octopus Energy’s billing 

With simplified utility bills, Octopus Energy aims to strip away the complexity that often comes with finances, with the continued effort of simplifying them further with welcomed customer feedback and input. 

Octopus Energy encourages the use of smart meters to provide concise billing, only charging you for the energy you’ve used. But if you don’t have a smart meter, don’t panic, Octopus Energy will accept a meter reading from you any time you’d like an up-to-date bill, and they will send you your statement within a few days. 

If you’re an Octopus Energy customer, you’ll receive a reminder to send a meter reading to them each month, but if you don’t send one within three months, then they will send you an estimated statement.

Octopus Energy’s customer service

Octopus Energy is rated the maximum 5 out of 5 stars on Trustpilot from an impressive 42,000 reviews, and with an average answer time of under 2 minutes over the past year, we’re not exactly surprised they’re so highly spoken of. 

Despite being deft hands at answering your calls, Octopus Energy encourages customers to see if their issues can be solved via the help provided within their online accounts. Customers can submit meter readings, let Octopus know if they’re moving home and change account details and preferences through the online account system. 

The customer service team is available seven days a week online and typically you can expect a response within a few hours.
