“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.”

Help the race against climate change

“As an international mountaineer I’ve been able to witness our impact on the natural world firsthand. 721 Challenge is a world record attempt, with the aim of bringing attention to our environmental responsibility and raising funds for the conservation of our planet’s most precious resource: its rainforests. That’s why I’ve partnered with Big Clean Switch, because their goals are in line with what we should all be striving for—a brighter, more sustainable future.”
Nick Hollis, Adventurer, 721 Challenge

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 tariffs work?

Renewable power sources like wind turbines and solar farms all feed their energy into the National Grid, like rivers running into a big lake. When you switch to a green tariff, your supplier guarantees that however much electricity you take out of the ‘lake’, the same amount of renewable electricity will be pumped in. The more people who switch to green tariffs, the cleaner the lake gets.
