We’re proud to announce that we’ve been named a Which? Eco Provider for the sixth year running.
Which?, the UK’s consumer champion, independently analyses and scores energy providers on their green credentials each year.
Only energy companies who score highest in Which?’s rigorous assessments can be named a Which? Eco Provider, so it’s a huge achievement to be recognised for the work we’re doing to build a greener Britain.
Why is Ecotricity a Which? Eco Provider?
Ecotricity has been a Which? Eco Provider ever since Which? first started rating green energy providers in 2021.
The Which? Eco Provider endorsement is reserved for energy suppliers who are the most sustainable; making the greatest positive impact in generating and sourcing renewable energy, helping customers cut carbon and reduce their greenhouse gas emissions.
“Generating, buying and selling renewable energy is a key part of energy supplier sustainability, and worth over half the points in our assessment.
But these aren't the only factors. We also looked at companies' greenhouse gas emissions, and how they help customers cut their carbon footprint, to get a fuller picture of suppliers' overall environmental impact”. Which? June 2026
Ecotricity was the world’s first green energy supply company when we were founded in 1995. Since then, we’ve built 74 windmills across 24 wind parks, as well as three sun parks and our first green gasmill.
That’s just part of the reason we’re Britain’s overall greenest energy company - the breadth and depth of our work on green issues is unmatched. Our not-for dividend business model means our profits are re-invested into building new green energy – we call it Bills into Mills.
We’re also the only energy company to offer officially vegan-certified energy, a certification we hold from both The Vegan Society and the vegan charity, Viva!.

Switch to Ecotricity and we’ll use your bill money to build new sources of renewable energy and build a greener Britain.
