“It's so easy to make a real difference by switching to a 100% renewable energy supplier. ”
- James Boyle, Climate Coalition -

Why go clean?

All of the tariffs on our site guarantee that the power you use in your home will be matched by 100% renewable electricity. A typical home could save over £270* by switching to the cheapest renewable electricity deals.
* Prices sourced from EnergyHelpline and correct as of 26 March 2018. The saving compares an average usage dual fuel household on a Big Six Standard Variable Tariff (£1,137/year) with an average usage dual fuel household on the cheapest tariff available through the Big Clean Switch(£877). All prices are for a single rate meter paying by monthly direct debit, with prices averaged across all regions of England, Scotland and Wales. Average usage as defined by Ofgem is 12,000 kWh pa of gas and 3,100 kWh pa of electricity. Average Big Six Standard Variable Tariff includes E.ON Standard price changes coming into effect from 19 April 2018.

Did you know

What's this all about?

An increasing number of skiers, mountaineers, climbers, hill-walkers, and mountain sportspeople are choosing to use clean energy in order to help preserve the environment and way of life that they love. As more people understand that they can do a good thing, and save money, our reliance on fossil fuels will reduce.

Protect the snow we love

Whether it’s skiing, boarding, climbing or just being at home in the mountains, for those of us with a passion for this way of life we know one thing – Snow is everything.

Climate change is affecting this. With warmer winters comes shorter seasons and less snow. This is a global issue, but we can all be part of the solution and protect the life we love.

Switch and save our snow!
