Why switch to green energy?

Green energy is cheap

We’ll hunt through the UK’s most reputable green suppliers to get you a great deal (green tariffs are now some of the most competitive on the market).

Engage your customers

88% of consumers want businesses to help them be more sustainable, and 73% of millennials are willing to try a product that supports causes they care about.

Help save the planet

Finally, there’s climate change. Faced with everything from commodity price volatility to flood risk, cutting emissions just makes business sense.

Why us?

Big Clean Switch has been helping British businesses make the switch to cheap green energy since 2016. Our team of experts take pride in offering jargon-free advice and helping you avoid suppliers’ hidden costs.

We’ll review the market to find you the best tariff for your business, and make sure you fully understand the options before signing on the dotted line.

How it works


One of our team of experts will talk through your needs so that they can find you the best tariff for your business. We’ll also get your permission to speak to your current supplier to get information about your past energy use. This ensures we can give you an accurate quote.


We’ll source the best gas and electricity prices from our panel of trusted suppliers, then explain your options so you know exactly what you’re committing to.


Once you’re happy, we’ll manage the switch process so you can relax, knowing that your business has a great energy deal and is doing its bit to help the environment.

Helping you shout about it

We’ll also help you communicate your switch to your customers, including providing you with materials to badge your products as being produced using green power. And of course, every one of your sites will get one of our fabulous window stickers for every year you’re powered on green electricity.
