“I have always wanted to change to a renewable energy company but was daunted by the process. Big Clean Switch made it very easy and answered all of my questions politely and patiently! The chat box helpline was fantastic and the same advisor helped me right up until I had switched.”

Our mission

Urgent action is needed to switch the world to low carbon power, and yet our energy system is broken: tied to fossil fuels, needlessly complex, and overpriced for those who can least afford it. We want to change that. Nothing should stand in the way of people making clean energy choices. Our mission is to switch every home and business in the UK to clean energy.

What is green energy?

‘Green 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), green energy is renewable and has little impact in terms of climate change and air pollution.

How do green energy 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. Just like with traditional energy, green tariffs use electricity from the National Grid, so even if the sun isn’t shining and the wind isn’t blowing, you will still have reliable power for your home.

How to switch to green energy

It couldn’t be easier to switch your home to renewable energy using our free and impartial service.
