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 greenest energy company.
Almost 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!
We’re ranked number one for our customer service!
We were thrilled to be ranked as the top energy supplier for customer service for July - September 2025 by Citizens Advice.
Citizens Advice is one of the most trusted, independent consumer organisations. They compare customer service performance from large energy companies four times a year, creating a star rating to help people cut through the marketing claims. Find out more here.
Vegan energy
Ecotricity is the only energy company in the world certified as vegan by both The Vegan Society and Viva!, the vegan charity.
As you’d expect, vegan energy is produced without involving animals. Renewable electricity from solar, wind and geothermal is therefore vegan.
Gas is more complicated. Several big energy suppliers use by-products from livestock farming in anaerobic digestion vats to produce biomethane, which is then delivered as household gas or burned to create electricity.
They call it ‘green gas’, but livestock farming is one of the biggest contributors to carbon emissions in the UK and around the world. Energy companies who use animals to make energy are supporting the factory farming industry, which is a huge problem for the climate.
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
The facts speak for themselves.
We’re proud to have been named a Which? Eco Provider.
We’ve built 24 wind parks all over the country, which are home to 74 beautiful windmills, as well as sun parks utilising the latest bifacial panels. And we’re always planning more, as fast as possible.
We’re the only energy company in the world certified as vegan and our green gasmills will soon be busy making sustainable gas from grass.
When you’re with us, every penny of your bill makes a difference in building new forms of green energy. You’ll help us make fossil fuels a thing of the past.
