About Green Star Energy
Formerly Pioneer Energy, the company supplied gas and electricity to residential customers throughout the UK. Green Star Energy’s stated mission was to provide clear and accessible energy services.
In 2018, Ofgem announced it had appointed Green Star Energy as the supplier of last resort for Future Energy customers when the latter went out of business.
