The future is clean

Solar power recently generated more electricity for the UK than coal and nuclear combined. A number of countries are already powered almost 100% by renewable energy. And huge corporations including Apple, BMW, Goldman Sachs, H&M and Sky have committed to going clean. Fossil fuels are yesterday’s news – clean energy is the future.


What is clean energy?

Clean energy is power generated from renewable sources – sun, wind, water (rivers, tides or wave power) and biofuels (usually gas released by rotting food and agricultural waste). Unlike electricity generated by burning dirty fossil fuels like oil, coal and gas, clean energy has very little impact in terms of climate change and air pollution.

Not just cleaner...

More than 60% of UK homes are guaranteed to save money by switching to the cheapest clean tariff. So far, we’ve saved our members over £165 a year on average.


What is a clean tariff?

Most of us get electricity from the National Grid. Picture the Grid like a bucket, full of clean and dirty water.* When you’re on a clean tariff, your supplier promises to match the amount you take out of the bucket by putting the same amount of clean water in. The more clean water that goes into the bucket (and the less dirty water), the cleaner the bucket, and therefore the Grid, gets.
* In real life, of course, water and electricity should not mix!

Quick and easy

We’ve made it super-simple to compare your current tariff with a range of clean suppliers. Once you’ve chosen the one for you, switching takes another few minutes. We’ll take care of contacting your old supplier too, so you can just sit back and relax.



Call us on 0800 037 0697, or click on the yellow chat symbol at the bottom of each page. You’ll be connected to a real person, right here in the UK. On the rare occasions when we’re having some downtime, your question will be emailed to us and we’ll get back to you as soon as we can.
