Tempus Energy founder and chief executive Sara Bell told Utility Week that the supplier has closed down and all of its customers have switched.
“We have asked Ofgem to revoke the licence of Jetstream Energy Supply Limited, the original registration name,” she added.
The independent supplier is quitting the supply market after securing £3.78 million of funding to help it develop a flexible smart electricity supply model in December last year. The investment was raised from high net worth individuals and existing shareholders, bringing the total funding secured by the company to just short of £5 million in 2015.
Tempus was also outspoken about the recent two-year investigation into the energy market by the Competition and Markets Authority (CMA), insisting it will not increase competition or incentivise customers to switch.
Bell added that Tempus Energy Technology would continue, focusing on international markets with liquid wholesale markets.
