Green Energy Comparison
E.ON Next
E.ON Next has a mostly renewable mix, with some fossil fuels and a small amount of nuclear. It offers specific green tariffs, such as Next Gust and Next Pumped, which are backed by 100% renewable electricity. The company also pledges to donate to the Woodland Trust to help restore ancient woodlands when customers choose a fixed tariff. It is also involved in projects to help decarbonise homes and was a finalist in the International Sustainability Awards 2026.[1]
Outfox Energy
Outfox Energy has a mix of fossil fuels and renewables, with some nuclear. The supplier buys Renewable Energy Guarantee of Origin (REGO) certificates to match the electricity its customers use, rather than generating its own. It does not currently offer a dedicated 100% renewable tariff or carbon offsetting schemes for domestic customers. It also offers a Smart Export Guarantee tariff to pay customers who generate their own electricity, such as from solar panels, and export it to the grid.[2]

Hi, I'm Rob, and I run Energy-Review.co.uk. I initially started this project in 2018 when I was looking to switch energy suppliers and found there wasn't a website that provided simple, data-backed reviews on all the suppliers available. Since then, I have spent a lot of time (too much, some may say!) looking at all publicly available data about each supplier and writing reviews using this information. These reviews are updated as regularly as possible, and any data is backed up by a source where necessary. I have also started writing guides on various energy-related topics, which hopefully you will find useful. If you find any issues, please use our contact form to let us know.
