Ecotricity vs the rest
Why should you choose Ecotricity instead of another energy supplier?
It’s a good question. Ever since we delivered 100% renewable electricity to our first customer in 1996, we’ve been proud to be Britain’s overall greenest energy company. It’s more than green energy — the breadth and depth of our work on green issues is unmatched.
Over 30 years on, there are a lot of energy companies out there who claim to offer green energy. But do their claims hold water? Who’s telling the truth and who’s greenwashing? And how can you tell?
Here’s why we think you should switch to Ecotricity:
We’re a Which? Eco Provider
We’re proud that we’re a Which? Eco Provider for energy. The Which? Eco Provider endorsement is given to energy suppliers who make the greatest positive impact in generating renewable electricity, building new sources of green energy and helping the transition away from fossil fuels.
We’ve been a Which? Eco Provider for five years – which is a fantastic achievement!
Vegan energy
Driven by the idea that energy could be both greener and more ethical without relying on animals, we reviewed all our energy sources and eliminated anything that involved animal use.
As a result, Ecotricity is now the only energy company in the world certified as vegan by both The Vegan Society and Viva!.
While some suppliers still produce energy from livestock waste, this still supports livestock farming, one of the largest sources of carbon emissions, meaning it continues to contribute to a significant climate impact.
Bills into Mills
Ecotricity is a not-for-dividend company. We put every penny towards building new sources of green energy and innovative green projects that help build a greener Britain. You can help us make a real difference in the fight against the climate crisis.
