Switching to green energy is one of the easiest and most impactful things you can do to reduce your carbon footprint. With Big Clean Switch’s free energy comparison service, you can compare deals from the UK’s best green energy suppliers and switch to a great value tariff in minutes.

Gone are the days when renewable energy was expensive. In fact, green energy tariffs are now competing with the cheapest deals on the market. We’re proud to save our customers hundreds of pounds on average by switching their gas and electricity with us. All while knowing that they’ve done their bit for the planet.
There are lots of energy providers in the UK offering green energy, but they’re not all equally environmentally-friendly. We verify the claims of all the companies that we work with to ensure that they’re greenwash-free. You can read more about our selection criteria here.
It couldn’t be easier to switch your home to renewable energy using our free and impartial service. Simply choose whether you need gas and/or electricity and provide a few details about your current provider.

Once you’ve chosen, we’ll handle the rest. Your new energy supplier will contact you to confirm the transfer date. There’s no need for engineers’ visits or any disruption to your supply. Plus, you’ll be backed by our Customer Service Guarantee so you can rest assured that we’re there to help in the unlikely event you have any issues.
‘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.

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.
