About Us

The Big Clean Switch is a 'social business'. We want to help as many people as possible switch to clean energy. By doing so, we help fight air pollution and climate change, as well as helping UK homes save money on their energy bills. Our goal is to make the world a better place and profit is strictly a secondary consideration (though the team still need to pay the bills). Find out more about how we're run here.

What do we mean by 'clean energy'?

Power stations, wind turbines and solar farms all feed their energy into the Grid, like rivers running into a big pond. When you switch to clean energy, your supplier guarantees that however much electricity you take out of the ‘pond’, the same amount of clean energy will be put in. The more people who switch to clean tariffs, the more renewable energy goes into the pond and the cleaner it gets.


About our suppliers

We only list tariffs where the supplier can guarantee that 100% of the electricity sold is matched by energy from renewables – sun, wind, water and biofuels. You can find out more about how we determine whether a tariff can be listed on our site in our Supplier and Tariff Selection Policy. If you have suggestions on how we can improve this policy, drop us an email.

Working in partnership

We’re working with the UK’s leading businesses, NGOs, councils and renewable energy suppliers to put the record straight, and in the process, make it as simple as possible for people to switch to cheap, clean energy. If you’d like to find out how your organisation can work with us, download our partnerships brochure.

How we cover our costs

Our costs are covered by the commission we receive from energy companies when members switch – usually around £30 for each fuel (electricity or gas). The commission doesn’t affect the price of the tariffs, which are the same price as they are on suppliers’ own sites (apart from where we’ve negotiated an exclusive deal that’s only available through Big Clean Switch).


What we do with the commission

When a member joins us through one of our charity or corporate partners, we pass on a third of the commission directly to the partner, often for use supporting good causes. The rest is used to pay off the money we’ve spent to create the campaign. We won’t make any profit for the first year or two, after which at least 5% of any profits will go to good causes tackling climate change, on top of the commission we pass back to partners.


Renewable Energy Sources

 Here’s a summary of where all our supply partners source their renewable electricity:
Figures for hydro may include electricity sourced from rivers, wave and tidal. Co-op Energy figures cover projections for electricity sourced under their community energy tariff (the only tariff of theirs we currently offer), rather than their whole renewables supply.

The Team

Jon Fletcher

Managing Director | Big Clean Switch

“Most people in the UK want clean energy, but don’t know how to get it, or think they can’t afford it. It’s our job to fix that!

Kasia Morgan

Campaigns Director | Big Clean Switch

“Every switch makes a difference, so please take the five minutes it takes to do a switch and encourage your friends and family to do the same. The more people that ‘go clean’, the quicker the UK will be able to move away from dirty, polluting energy sources.

Rebecca Walker

Partnerships Director | Big Clean Switch

“Our goal is to make the world a better, cleaner, sustainable place, while recognising that cost matters and convenience is king. We’re here to make it hassle-free and financially compelling for you to do the right thing. Please join us in this energy revolution!”

Ollie Wilson

Campaigns Manager | Big Clean Switch

“As an individual, your actions have the ability to make a difference to the future of our planet. Switching your home to renewable energy can save 1.5 tonnes of CO2e entering our atmosphere per year. That’s the equivalent to taking a car off the road for 6 months!”
