Green Energy Comparison
E.ON Next's green energy approach
According to Citizens Advice data, E.ON Next supplies a mostly renewable mix, with some fossil fuels and nuclear energy. The supplier offers 100% renewable electricity on specific green tariffs, such as Next Gust, which is backed by UK wind generators. For its standard renewable claims, it matches usage with Renewable Energy Guarantee of Origin (REGO) certificates rather than generating the power directly. The company has a target to reach net zero emissions by 2050. It also includes a one-off donation to the Woodland Trust for customers who sign up for its fixed tariffs, pledging to donate £500,000 over three years to help restore ancient woodlands.[1][2]
OVO Energy's green energy approach
According to Citizens Advice data, OVO Energy supplies a mix that is largely fossil fuels, with some renewable and nuclear energy. Despite this, the supplier runs a "Plan Zero" strategy with a target to reach true net zero by 2035. Its Plan Zero strategy limits its reliance on carbon offsets to a maximum of 10%. Customers can choose to add a "Greener Electricity" upgrade to their tariff to support renewable generation. As part of its sustainability investments, the company has planted 5 million trees in the UK since 2015 on behalf of its customers.[3][4][5]

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.
