In which areas does 100Green perform well?

With an excellent score of 100 in our Energy Suppliers assessment, 100Green achieves full marks in all three categories of our assessment – the Environment, Animals and People.

In terms of the environment, 100Green achieves the top score in the Environmental Report criterion, due to its extensive sustainability policies and commitment to environmental progress. Additionally, as 100Green’s electricity fuel mix is 100% renewable, the brand receives a top rating for the Energy Mix criterion. 100Green is also not involved in the nuclear power industry and therefore receives a top rating for Nuclear Power.

100Green also performed well for People. This includes a top rating in the Political Donations category, as 100Green was not found to have made any political donations in the past five years.

What makes 100Green so sustainable?

100Green has been supplying green energy for over 22 years. The company prides itself on being the UK’s only energy supplier that offers not only 100% renewable energy but also 100% green gas. This means that no fossil fuels were used in the production of 100Green’s gas and electricity supply, making it the ideal option for households looking to lower their carbon footprint.

100Green also seeks to assist its most vulnerable customers in paying their energy bills, which has been a primary focus for the company in recent years. Offering a phone-first service means a case-by-case approach can be taken, offering the right support for each individual. Additionally, 100Green proactively works with StepChange to support customers struggling with their finances.

100Green is also dedicated to being a business with a positive social impact, which is reflected in its recent work with Rural England Supporters’ Group. 100Green works with the organisation to improve the economic, social and environmental wellbeing of rural areas in England.
