Next up date due October 2022

All energy suppliers 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 Bulb Energy’s Fuel Mix Disclosures for the latest reporting year as well as all previous years. We will update this page with the latest data as it becomes available.

Bulb Energy claims to be “The Biggest Green Supplier”. With respect to renewables it makes the following statement on its website.

“We’re proud to be the UK’s biggest green supplier. We provide our members with 100% renewable electricity from solar, wind and hydro. Plus, our gas is 100% carbon neutral. 10% is green gas produced from renewable sources like food or farm waste. And we offset the rest of the gas we supply by supporting carbon reduction projects around the world.”

And they have lived up to their promise. Since Bulb launched its first domestic tariff in Febraury 2016, they have been supplying 100% renewable electricity all the way.
