Bulb supplier rating 2018

bulb supplier rating

Bulb scored five out five stars in our 2018 survey of UK energy customers. Customers gave Bulb top marks for how easy it was to switch to the dual fuel supplier as well as for value for money and customer service. The survey, conducted annually by uSwitch, included more than 17,000 energy customers and is the largest survey of its kind in the UK. The supplier scored an impressive 92% in overall customer satisfaction in 2018.

About Bulb

Bulb entered the UK energy market in 2015, with the specific aim to offer affordable green energy via their 100% renewable electricity and 10% renewable biomethane gas taiff.

The London-based energy company was founded by two former energy industry workers, who paired up to offer "A fair and open energy company, with an engaged supportive community that takes centre stage."

The Bulb Community, as they call it, is an online group where customers can not only ask questions about their specific account, but have actual input in how the company is run. This includes everything from requesting opinions on the functionality of their website to asking to members to share customer service horror stories.

Bulb renewable energy tariffs

Bulb attempts to cut through the confusion of the energy market but offering just one, variable rate renewable energy tariff to electricity-only and dual fuel customers.

The renewable electricity is generated from sources including hydro, wind and solar.

The renewable gas is generated by taking slurry from piggeries in Oxfordshire and then anaerobically digest it to make biomethane.
