Truly green energy

Welcome to Britain’s greenest energy company. All our electricity is certified green, and also certified vegan. Our gas is a mix of carbon-neutralised natural gas and sustainable green gas.

What makes us different is that we turn your Bills into Mills. So, instead of paying dividends we invest your bills in building new forms of green energy. And, you can be absolutely certain that the energy we supply will not be greenwashed.

Joining Ecotricity is one of the biggest things you can do to help fight climate change.

Sustainable green gas

We’re busy building green gasmills, making sustainable gas from grass and pumping it into the local grid. The carbon from burning the gas is reabsorbed when the grass grows back – no fossil fuels required.

We can make enough green gas to power every home and business in Britain, without taking away land for food production. And it’s perfect for our existing boilers, heating our homes and water without the hassle of installing expensive heat pumps.

Ethical pricing

We’re Britain’s greenest energy company and we operate an ethical approach to everything we do, including pricing.

We set our prices at a level that allows us to do our job of building new sources of green energy - as we seek to end the use of fossil fuels in the energy sector.

We are a not for dividend company, the money we have (all of it) goes into our mission, to green up Britain. You can read more about our energy tariffs here.

We've been fighting climate change for 30 years

When we launched in 1995, we were Britain’s only green energy company and we founded the global green energy movement.

Since then we’ve grown and grown, building wind and solar farms to power homes and businesses across the country. As we celebrate our 30th anniversary we continue to lead the way with pioneering innovations in green energy.

On 13 December 1996, the first of many truly magic moments in the history of Ecotricity took place. We completed our first ever windmill. And it’s been turning ever since.

In 2002, we added two more windmills to our collection. Situated near Mablethorpe in Lincolnshire, they were the first in the county and began turning in July.

Up until 2003, we’d only ever supplied energy to businesses, but never homes. Finally, we were ready and able to supply green electricity to homes across Britain.

In 2007, Al Gore presented our founder Dale Vince with the Ashden UK Award for work in the area of renewable energy.

On 1 August 2013, we introduced 100% green electricity for all our customers. Up until that point we had two tariffs – New Energy, which was about 60% green; and New Energy Plus, which was 100% green for a small extra cost.

Ecotricity became the first energy supplier to offer vegan electricity certified by Viva! and The Vegan Society in 2018.

In 2022, we built two new sun parks in Bulkworthy (near Galsworthy Farm), Devon and Dalby, Leicestershire, with the latest solar panel technology, next to our existing wind parks at both sites.

Recently, we completed the build of our very first green gasmill in Reading. Creating green gas made from grass, the mill is now feeding into the National Grid and will provide enough green gas to supply 6,000 homes.
