About 100Green

100Green is the only energy suppliers in the UK that supplies customers with 100% green gas and 100% renewable electricity. The supplier utilises sources including hydro, solar, wind and organic waste material.

100Green reviews

As of July 2023, 100Green has a TrustPilot score of 4, though the vast majority of those reviews will have been left when it was known as Green Energy UK. The positive reviews focus on the green energy it provides as well as its strong customer service.

Does 100Green have an app?

100Green has a mobile app that iOS and Android users can download for free to help manage their energy account.

Can I get a smart meter with 100Green?

100Green offers smart meters to customers. You can get in touch with them by email or phone to arrange a free installation.

Does 100Green offer energy efficiency products?

100Green doesn't offer energy efficiency products, but it does buy excess energy generated by those who have solar panels.

Is 100Green exempt from the price cap?

100Green was granted a permanent exemption from the price cap because it goes above and beyond when it comes to generating and supplying renewable energy to customers. This means that it can charge more than the price cap unit rate on its SVT as long as customers have actively chosen to be on it.
