Making energy simpler, cheaper, greener 

We're proud to be the UK's biggest green supplier. We provide our members with 100% renewable electricity from solar, wind and hydro. Plus, our gas is 100% carbon neutral. 10% is green gas produced from renewable sources like food or farm waste. And we offset the rest of the gas we supply by supporting carbon reduction projects around the world.

Hayden and Amit, the founders of Bulb energy met five years ago when they were working in the old energy industry. They saw the same problems at all the big providers. Inefficiency. Poor service. Expensive tariffs. Dirty energy. It didn’t have to be like this. The energy industry can change – and they set up Bulb to lead that change.
