About Affect Energy

Affect Energy was founded in 2016 as a small, independent energy supplier. Based in Shoreham by Sea, its headquarters are near Brighton in West Sussex. Despite its new beginnings, the team behind the brand had over 50 years of experience working in the UK energy market. Therefore, it had some pretty firm and knowledgeable foundations.

Affect Energy began with the aim to provide energy that was ‘simple, painless and great value for money’. From their years of experience, its creators saw that customers wanted two things:

  • cheap gas and electricity
  • for their energy supplier to actually do what they promised

Affect Energy therefore developed the saying ‘simple, brilliant energy’. By combining experience with a desire to change the energy business for the better, and placing a firm focus on developing great customer service, it sought to provide this simple, brilliant energy to all its customers.

In August 2018, energy provider Octopus Energy bought Affect Energy. The move was good for both parties. Octopus Energy acquired one of its small rivals, and Affect Energy got the opportunity to develop and offer more services to its customers by joining the Octopus family. Affect Energy founder and boss, John Szymik, noted at the time:

“I am proud that we have built a business so beloved to customers... Octopus stood out among all energy retailers as the best company to take this to the next level, and I’m delighted at the opportunity this creates for our team and our customers.”


  • 2016 - Affect Energy is founded by John Szymik.
  • 2018 - It has 22,000 customers and constantly ranks highly for customer service on review sites.
  • August 2018 - Octopus Energy buys Affect Energy.

Affect Energy and Octopus Energy

Octopus Energy’s purchase of Affect can be a bit confusing for current and potential customers. Does it mean that Affect Energy no longer exists? Not exactly. The Affect Energy website is still functional and potential customers can still buy Affect Energy tariffs. The supplier has also retained its own contact information.

However, the purchase does mean that as an Affect Energy customer, you are also an Octopus Energy customer. Octopus Energy will supply your gas and electricity.

Fuel mix

Affect Energy customers will be very pleased to know that, as the supplier is now part of Octopus Energy, all of its energy is 100% renewable.

Affect Energy Tariffs & Prices

Information in this guide is no longer being updated since the closure of this supplier. All information presented here is for reference purposes only. For more up to date information please contact the new supplier directly.

Sticking to its aim of keeping energy simple and painless, Affect Energy only offers two tariffs to new customers: its standard tariff and its fixed-rate tariff. Both function with standard and Economy 7 meters, and both can be taken out for gas, electricity or dual fuel.

Unlike a lot of providers, Affect Energy only offers one payment method: monthly direct debit. They do not support prepayment meters and do not allow you to pay on receipt of your bill each month.

Standard tariff

Affect Energy’s Standard Tariff is a variable tariff. This means that the unit rates can change depending on fluctuations in the overall price of energy. As it's a variable tariff, it doesn't have a set contract length and therefore there are no exit fees if you decide to terminate the contract and move to another provider.

If you do not have a contract with Affect Energy but receive its energy supply (eg. you have moved into a house that gets its energy from Affect Energy), you will automatically be charged its standard tariff rates.

Fixed rate tariff

Affect Energy only offers one fixed-rate tariff to new customers at any given time. This tariff has set unit rates for a year, after which you will automatically be put on the standard rate tariff, unless you take out another fixed rate tariff or swap suppliers.

As with the standard tariff, this tariff does not include an exit fee. You will not have to pay if you decide to cancel your tariff agreement.

Affect Energy Login: Access your Online Account


As Affect Energy is still selling its own tariffs with its own branding, despite being bought by Octopus Energy, customers still have access to the Affect Energy online account system, known as MyAffect. Through here, you are able to do the following:

  • Manage your Affect Energy tariff
  • Monitor your consumption
  • Submit meter readings
  • View your payment history

Logging into your MyAffect account as a customer is easy. Let’s break the process down step by step.

  1. Go to the Affect Energy homepage. You can do this by typing Affect Energy into your search engine. Click on the result that reads Affect Energy - Simply Brilliant Energy (it should be the first one) and you will be taken straight to the homepage.
  2. In the top right-hand corner of the homepage, the words MyAffect are located inside three triangles (when you hover over the words, the triangles spin around and MyAffect lights up in pink). Click this.
  3. You will now be on the Affect Energy Login page.
  4. On the pink line that reads Email*, enter the email address associated with your energy tariff (you will have provided this when you signed up for your tariff).

  6. Click the pink button underneath that reads Log in.
  7. If you have entered all of your details correctly, you will now have logged in to your MyAffect account.

Forgotten your login password?

Forgetting your password doesn’t mean you can’t access your MyAffect account. If your password has slipped your mind, you can reset it in just a few simple steps.

On the Affect Energy login page, you will see the words RESET YOUR PASSWORD located on the left-hand side. Click this. You will now be asked to type your username or email address onto the pink line.
