Green energy comparison
E.ON Next
E.ON Next supplies a mostly renewable mix, with some fossil fuels and nuclear. It offers a dedicated green tariff, Next Gust, which provides 100% renewable electricity backed by agreements with UK wind generators. Other specific tariffs, such as Next Pumped, also come with 100% renewable electricity sourced from its own renewable assets, independent UK generators, and renewable energy certificates. As well as this, the supplier has partnered with the Woodland Trust to support ancient woodland restoration, pledging a minimum donation of £500,000 over three years and making a one-off donation for every customer who signs up for a fixed tariff.[1][2]
Utility Warehouse
Utility Warehouse supplies a mix that is largely fossil fuels, with some nuclear. The supplier recently stopped using Renewable Energy Guarantees of Origin certificates for its tariffs to keep its prices low. It supports the Smart Export Guarantee, which allows customers who generate their own renewable electricity to get paid for sending it back to the grid. It also highlights green initiatives on its main website, though its standard fuel mix remains heavily reliant on fossil fuels.[3][4]

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.
