The Biggest Green Supplier

Bulb is 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.

Independent Generators

We buy our energy from independent renewable generators from across the UK, like Gail and Miles from Old Walls Hydro in Dartmoor. Wherever possible, we have direct relationships with these generators to purchase their electricity. We buy the rest from the wholesale market. We source our energy from solar, wind and hydro. They're a pretty impressive bunch, our generators.

The Best Kind Of Energy

Which do you choose: energy that harms the planet or energy that doesn't? Exactly. 100% of Bulb's electricity is renewable. And our gas is 100% carbon neutral. Win win.

Every year, the average Bulb member saves 3.5 tonnes of CO₂ from entering the atmosphere. That's like planting 1,770 trees.
