Green energy for all

We provide our members with 100% renewable electricity from solar, wind and hydro. And our gas is 100% carbon neutral too. We offset the emissions from the gas we supply by supporting carbon reduction projects around the world. Plus, we're one of the biggest buyers of green gas for homes in the UK so a chunk of our gas mix comes from renewable sources, too.

Our generators

We source our electricity from wind, solar and hydro, and work with generators of all different sizes, from small-scale sites like Tyn y Cornel Hydro in Snowdonia to large-scale off-shore wind farms.

Sometimes we partner with generators to directly purchase their electricity. Where we don't, we buy electricity on the wholesale market with renewable energy certificates to match.

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.

By going green, the average Bulb member lowers their carbon impact by 3.2 tonnes of CO2 a year. That's the hard work of around 1,590 trees.

Doing the right thing

As a certified B-Corp, we're working to demonstrate how business can be a force for good. For every new member that switches to Bulb, we donate £2 to Bulb Foundation which makes grants to charities and social enterprises tackling the climate crisis head on.
