Affect Energy Fuel Mix Disclosure

All suppliers, including Affect Energy, are required to provide information about the mix of fuels they use to generate the electricity they supply to their customers. They also need to disclose the environmental impact of this fuel mix.

This information is known as the Fuel Mix Disclosure and is published annually.

Shown below is Affect Energy’s Fuel Mix Disclosures for the latest reporting year as well as previous years. We will update this page with the latest Fuel Mix Disclosures as they become available.

On its website Affect Energy states:

“We source all of our electricity direct from the grid; this means our fuel mix mirrors that of the UK as a whole. We don’t buy specific energy contracts for specific fuels – we just try to get it at a great price for you.

At the moment, the way electricity is distributed means all the energy going into your home comes from the central grid system; this means a 100% ‘renewable’ tariff doesn’t mean you’re being supplied 100% renewable energy to your home.

The UK’s making great moves in developing renewable energy, and we’re fully behind this. And as the cost of renewable energy falls, we’re hoping this will have a knock on effect on the cost of supplying clean energy to you.”

Affect Energy Fuel Mix 2017/2018

The company has not made a fuel mix disclosure for 2017/2018.

Affect Energy was acquired by Octopus Energy on 31 August 2018. Since then, we expect that the Affect Energy fuel mix will be more or less similar to that of Octopus Energy, but can’t be sure.

Affect Energy Fuel Mix 2016/2017

The table below shows the Affect Energy Fuel Mix Disclosure for the period 1 April 2016 to 31 March 2017.

Compared to the UK average Affect Energy’s fuel mix comprised more than average use of coal generation – bad from an environmental perspective – but also a higher proportion from renewables – good from an environmental perspective. While they did not properly disclose their carbon emissions it is likely that these two electricity sources would have, more or less, balanced out. So overall carbon emission levels were probably close to the UK average.

Their purchases of electricity from nuclear energy sources were well below the UK average. As a result, radioactive waste was likely below the UK average.
