As well as this, the supplier pledges to donate a minimum of £500,000 over three years to the Woodland Trust to help restore ancient woodlands, with a one-off donation made for every fixed tariff sold.[1]
Outfox Energy
Outfox Energy supplies a mix made up mostly of fossil fuels and renewables, with some nuclear.

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.
