What is clean energy?

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

How do clean tariffs work?

Picture the National Grid like a bucket full of water.* When you’re on a renewable 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 reality of course, water and electricity shouldn’t mix!

Switch with confidence

At Big Clean Switch, we keep a careful eye on the customer service performance of the suppliers we work with to make sure they’re up to scratch. We’re so confident in them, we make a simple promise to every single home that switches with us: In the event that you have a problem you can’t resolve directly with your supplier, we’ll take it up with them on your behalf. We call it planet-friendly peace of mind.
