Bulb Energy was set up by two friends who used to work in the energy industry. Recognising that all the big energy suppliers were guilty of inefficiency, poor service, bad tariffs with no transparency, they decided to set up a fair and open energy company, with an engaged, supportive online community taking centre stage. With more than 1.7 million customers, Bulb is now taking on the Big Six energy providers. They keep things simple, with one tariff for electricity and gas. Bulb Energy supplies 100% renewable electricity and 10% green gas which is 100% carbon neutral. Bulb makes sure that each unit of its electricity supplied is matched 100% with electricity generated from renewable sources.
