How it works. All electricity in mainland UK comes to you through the national grid, which is a dirty pond of power from different sources – coal, gas, oil, nuclear and renewables. When you switch to Good Energy, we add more green energy. It won’t go straight to your socket, but the amount of renewable electricity in the grid goes up. It’s like pouring fresh water into this dirty pond. Slowly but surely we’ll clean it up.

All our electricity is renewable. Our main tariff is fully verified by the Green Energy Supply Certification Scheme so you can be sure it provides a real, measurable environmental benefit to the country.

Generated by a growing community of over 12,000 independent, local suppliers across Britain. One in three of these are Good Energy customers, so buying your electricity from us is like buying it from a farmers’ market rather than a supermarket. It also encourages more people to produce their own green energy from sunshine, wind and water.

Made from British weather (and a few plants and trees) – sunshine, wind, water and sustainable biogeneration. This last one is when greenery is burned and turned into electricity, releasing as much carbon dioxide as it does if it decomposes naturally. And because we make sure any plants used are replaced it’s sustainable too.

We only buy electricity from generators that pass our strict purchasing policy. One of the toughest in the industry, it means we not only know our electricity doesn’t increase the amount of carbon dioxide in the atmosphere; we also know its generation has as little impact on the surrounding natural and human environments as possible.

We supply gas too. We’re helping to grow renewable heat in the UK with our Gas+ tariff.
