Life can be complicated. Your energy doesn't need to be.

Here at Bulb we keep things simple. We have one tariff for electricity and gas, and it's the lowest offered by any 100% renewable electricity company in the UK. Come to think of it, it's lower than most non-renewable providers too.

Bulb supplies 100% renewable electricity and 10% green gas at prices that don’t cost the Earth.


Greening up the grid.

When you switch to Bulb, we make sure that for every unit of electricity you use, a unit is produced and put on the grid by a pollution free renewable source like Llyn Brenig Hydro in North Wales.

In addition, 10% of our gas comes from biomethane. That’s gas produced from organic matter like sewage and manure - which is then reinjected onto the grid (minus the smell).
