Who is One Big Switch

One Big Switch is not a power company, we’re a people power company. We use the huge buying power of our members to unlock group-discounted electricity and gas offers. These discounted rates help our members pay less for their energy bills.

Started in Australia in 2011, One Big Switch now has over 1 million members worldwide. Every year we help tens of thousands of our members save on their energy bills. We do this by giving them access to exclusive “members only” group discounted energy rates.


All our offers are obligation free. We built One Big Switch to help you find better deals on energy, but taking an offer is your choice. If you decide to switch, you can do it right on our website, quickly and easily. 

One Big Switch launched in the United States in 2015, and already has over 60,000 members in Texas and New York alone. The tremendous buying power of our membership makes us the largest discount energy club in North America and has quickly unlocked exclusive group discounted energy rates for our Texan and New York City members. Only One Big Switch members get access to these discounted energy rates.
