What we do is unique - we take the money you spend on your electricity bills and turn it into new sources of green energy. Because we run on a not-for-dividend business model and have no shareholders or investors to keep happy, we’re free to dedicate all our money to our mission: changing the way electricity is made.

So we take the money our customers spend on their electricity bills and we use it to build new forms of clean power - wind turbines. We like to think of it as ‘turning electricity bills into windmills’.

Check out how green (or not) your current supplier is...

Yes. Changing the way we make our electricity is the biggest single thing any of us can do to fight climate change, because conventional, or ‘brown’ electricity is the biggest single cause of climate change in the UK - responsible for over 30% of our CO2 emissions.

And the greatest change you can make is switching to Ecotricity. We came top of the green build league again in 2008, continuing our commitment to create and build more sources of green electricity than any other power company. Over five years we’ve spent an average of £450 per customer per year building new sources of green energy. Our closest rival spent less than £30 per customer over the same period.

There are two. Our main tariff is New Energy, dedicated to new build, this is the greenest tariff in the UK bar none - and price matched to the Big Six. We also offer New Energy Plus for people that want a 100% green supply now, while we build more. More on our tariffs.

No. Typically it will cost nothing more, because our policy (and our promise) is to match the standard price of regional suppliers for their ‘brown’ electricity across the UK.

Most people are still with their regional supplier so switching to Ecotricity won’t cost a penny more. If you’ve switched to a cheaper deal though, we will cost a little more - we can’t price match the price cutters and keep building new sources of green energy.

Yes. Because we’re not a conventional power company - we don’t think like one or act like one. For one thing we answer the phone… ourselves. Call and you’ll speak to one of us, somebody who knows what we do and is keen to help you. We believe our service is actually the very best in the industry.

It couldn’t be easier. You can sign up in about five minutes online, or by calling us free on 08000 302 302. That’s all you have to do, we’ll take care of the rest.

Definitely. By using the national grid, which we are all already connected to, we can supply your home no matter where you live in mainland UK.

No. You will continue to receive your electricity in the same way as you do at the moment. There's no need for new cables or wires. The only difference, and it's a big one, is that you'll be helping to change the way electricity is made.
