GB Energy

GB Energy Supply went out of business on 26 November 2016, citing recent increases in energy prices making its business 'untenable'. 

Established in 2014, by 2015 GB Energy Supply’s tariff was among the cheapest on the market. But just a year later, it stopped trading.

At the time it went bust in November 2016, GB Energy Supply had 160,000 customers. It blamed ‘swift and significant increases in energy prices over recent months’ for its failure. As well as its inability, as a small energy company, to bulk-buy energy in advance in order to ‘access the best possible wholesale prices’.

GB Energy Supply’s customers were transferred automatically to Co-operative Energy. Find out more about GB Energy Supply going bust.

GB Energy Supply initially offered only one simple tariff, Premium Energy Saver, which was a standard (variable) tariff and was the cheapest on the market for a medium dual-fuel customer in May 2015.

But GB Energy customers saw their bills go up by 30% from 13 October 2016. This followed an August 2016  increase in its gas and electricity prices (of 7%).
