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 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

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.

Affect Energy Standard Tariff

Electricity unit rate 15.897p per kWh
Electricity standing charge 20.90p per day
Gas unit rate 2.993p per kWh
Gas standing charge 17.85p per day
Total estimated cost per month £80.13
Total estimated cost per year £961.61
Exit fee £0

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.

The name of this tariff seems to change every few months. For example, at the time of writing, Affect Energy is offering Affect Energy Fixed September 2020 v2. The unit rates differ slightly between the tariffs as they are based on the market price of gas and electricity the month they are created.

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

Affect Energy Fixed September 2020 v2
Cost Type Price
Electricity unit rate 15.719p per kWh
Electricity standing charge 20.90p per day
Gas unit rate 2.909p per kWh
Gas standing charge 17.85p per day

How does Affect Energy compare to the market average?

While not the be all and end all, price plays a very important part when determining which energy supplier to go with. No one wants to pay an arm and a leg for their energy! Using Ofgem’s energy price cap (currently £1,042) as the market average, we ran some quotes to see how Affect Energy’s Standard Tariff fares in terms of price.

Ofgem Energy Price CapOfgem, the energy regulator in the UK, has placed an annual cap on the price of energy. This means that energy suppliers cannot charge new customers more than the dictated amount for gas and electricity.The price cap is currently £1,042.

With an average quote of £961.61*, Affect Energy is a comfortable £80 under the price cap. Being this far under suggests the supplier’s prices are very reasonable. While we have seen cheaper prices out there (from Utility Point and Bulb, to name just a few), Affect Energy is still securely on the cheaper side of the scale.

*all figures are based on a 2-3 bed house with 3 occupants in central London. Figures will vary depending on the region, house size and number of occupants.

Affect Energy Reviews & Verdict

What are customers saying about Affect Energy? What’s our conclusion here at Selectra? Let’s look at some Affect Energy reviews to find out.

Affect Energy Customer Reviews

Since its creation in 2016, Affect Energy has consistently been praised for its great customer service, and little seems to have changed in this regard since Octopus Energy acquired the supplier.

Affect Energy still features on Trustpilot, but we did notice that customers leave comments here for both Affect and Octopus — which is no surprise seeing as the two are now intertwined. Here, Affect Energy has an outstanding rating of 4.9 out of five stars, with 88% of the more than 2,000 reviews rating the supplier as excellent. There doesn’t seem to be much room for improvement here. Customers applaud its customer service, as well as how easy it is to deal with the supplier.

As boring as it can be to work with an energy supplier, Affect/Octopus Energy make everything so simple and actually a delight, from the minute you begin using them… Anonymous customer, Truspilot.

Google reviews tells a very similar story. With another great rating of 4.7 out of five stars, customers rave about the great customer service, easy to use website, and also throw in praise for Affect Energy’s reasonable pricing. Likewise, its rating of 4.7/5 on Facebook suggests even more satisfied customers.

2 years with Affect now. No problems at all. I have phoned them twice, calls answered almost immediately, answered politely and the correct action taken by the agent. I can’t ask for more! Chris, Google Reviews

While customers leave their own reviews about Affect Energy, it’s also worth noting what customers think of Octopus Energy if you're considering switching. Head to Selectra’s Octopus Energy reviews guide to read customer reviews and see how we rank the supplier based on customer service, pricing, billing, account management and complaint handling.

Selectra’s Verdict

Based on the praise pouring in from customers and its reasonable pricing, Affect Energy seems to be a good supplier that has stuck to its promise to deliver a good and straightforward service to its customers. We are very pleased that the Octopus Energy buyout doesn’t seem to have changed any of this.

Where Affect Energy perhaps falls short is with its options. With just two tariffs, one payment option and a lack of additional services (such as services that help you save and use less energy), customers have limited choice.

All things considered, we give Affect Energy three out of five stars. It does what it says on the tin, provides good energy in a simple way, but if you want a little more, a bigger supplier might be a better option. If you just want the basics for a good price, then Affect Energy could be a good fit.

Positive customer service reviews Only one payment method - monthly direct debit
Easy to use website for purchasing tariff and managing it thereafter Only two tariffs to choose from
