What is clean electricity?

By ‘clean electricity’ we mean power generated from renewable sources – sun, wind, water (rivers, tides or wave power) and biofuels (such as gas released by rotting food waste). Unlike electricity generated by burning fossil fuels (oil, coal and gas), clean energy has little impact in terms of climate change and air pollution. No tariffs available through our site source electricity from nuclear power. Click here to find out more.

How do clean tariffs work?

Picture the National Grid like a bucket full of water.* When you’re on a clean electricity tariff, your supplier promises to match the amount you take out of the bucket by ensuring the same amount of clean water goes in. The more clean water that goes into the bucket (and the less dirty water), the cleaner the bucket (or the Grid) gets.
 
* In reality of course, water and electricity shouldn’t mix!

More power from your switch

Whenever anyone switches energy company through a third party like the Big Clean Switch, the supplier pays a commission. This doesn’t affect the price of the tariffs we offer, which are the same price, or even lower, than they are on suppliers’ own websites.

For every home that switches to renewable energy, Big Clean Switch will be donating on average £20 to help fund community owned solar energy projects in Greater Manchester. Your switch helps to put up solar panels!
