Bulb supplier rating 2019
Bulb scored four and a half out five stars in our 2019 survey of UK energy customers. Customers ranked Bulb first in the Green Services, Best Deal for You and Transfer Process categories. 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 81% in overall customer satisfaction in 2019.
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.

2019 Bulb energy price changes
In February 2019, when many suppliers raised prices in reaction to Ofgem's price cap rise, Bulb announced it would lower its prices. The supplier cut its gas prices by 2%, or around £20 a year, effective 21 March 2019.
Bulb announced three prices rises in 2018, with the most recent price hike being 11.1% — an annual increase of £102 for dual fuel customers. This rise took effect 11 November 2018.
Rik Smith, uSwitch Energy Expert, said of this third price rise:
"Customers have the huge increases in wholesale energy costs to thank for this latest hike, but that will be of little consolation to the 600,000 who will be directly hit by this news.
“This is a case of third time unlucky for Bulb customers and a sharp reminder that, for peace of mind, customers should fix their energy tariff. Just as the cold weather kicks in, Bulb customers now have to face the prospect of paying an extra £102 per year for their energy.
“It’s never been more important to shop around for the best energy deal. As well as saving up to £482 a year, fixing your energy will protect you from the relentless barrage of price rises and provide much-needed peace of mind as we head into winter."
In June 2018, Bulb announced a price rise of 5.1% — an annual increase of £45 on average — and gave customers 60 days' notice before the increase would take effect (double the notification period required by Ofgem).
The energy supplier cited wholesale increases of 21% since their last price rise, which was in February of the same year.
In February, Bulb's price rise checked in at 2.8%, and was effective from 28 April.
Previous year price rises from Bulb Energy
In April 2017, Bulb announced a price cut to its dual fuel variable rate tariffs of 2.5%, effective immediately.
In November 2016, Bulb announced a price rise of 9%, effective the following month.
