Bulb Energy Ltd. was incorporated in April 2013 under Regent Power Ltd. and was known as Hanbury Energy Ltd. between June and October 2015.^[4] Its parent company is Simple Energy.^[5] From the start of trading, the directors were Amit Gudka, a former energy market trader for Barclays, and Hayden Wood, a former management consultant.^[6] Gudka stepped down from day to day activities at Bulb in February 2021 to focus on his new battery storage startup.^[7]

Initial funding came from the founders' savings and from their personal contacts. The backing was then obtained from JamJar Investments.^[8] In August 2018 a further £60 million funding was secured from two backers: DST Global (owned by Russian billionaire Yuri Milner), and US hedge fund Magnetar Capital.^[5][9] By 2018, the company was worth between £400M and £500M.^[5]

Growth was rapid from the start of 2017, and by early March 2019, the company had over 1 million customers and was employing over 550 staff.^[5] Its headquarters moved in February 2019 from offices at Hanbury Street, Shoreditch to Bishopsgate in the City of London.^[4]

In 2018, Bulb was the UK's largest renewable energy supplier, and the UK's seventh-largest energy supplier, smaller only than the "Big Six".^[10] It was the only company to achieve this growth without taking over other companies, as rival companies had done.^[11] SyndicateRoom identified Bulb as the UK's fastest-growing private company of 2018.^[12]

Special administration and acquisition edit

In September 2021, Bulb sought a bailout due to financial problems caused by sharply increasing natural gas prices.^[13] In November 2021, Bulb became the first energy company to go into Special Administration, under which it will be run by the government through the regulator Ofgem.^[14][15][16] This process will allow the government the option to make grants and loans to the business while the administrators work to transfer customers and sell the business in parts or whole.^[14]

The government set aside £1.7 billion to cover the company's trading costs and the cost of the administration.^[17] According to the Financial Times, at least two energy suppliers offered solutions that would have allowed Bulb customers to be switched to alternative providers at a reduced cost to consumers and taxpayers.^[18]

The company's subsidiaries in France, Spain, and Texas were unaffected by its entry into administration.^[19] Teneo were appointed administrators of Bulb in the UK on 24 November,^[20] and Interpath were appointed for Bulb's parent Simple Energy.^[21]

In October 2022, Octopus Energy agreed to acquire Bulb's 1.5 million customers.^[22][23] The acquisition was completed on 21 December 2022.^[24]

In the year 2018–2019, Bulb's renewable electricity was generated as follows: 73% from wind power, 24% from solar power, and 3% from hydroelectricity. Bulb's carbon-neutral gas was composed of 10% biogas and 90% carbon offset.^[25]

Bulb announced in June 2019 that they were expanding to France, Spain, and Texas.^[26]

In August 2020, Bulb agreed to pay £1.76 million in redress, refunds, and goodwill payments after industry regulator Ofgem found 11,400 customers had been overcharged, together with other mistakes (some self-reported by Bulb).^[27]
