Over the past decade there has been an influx of small- and medium-sized entrants to the U.K. gas supplier market, which is supervised by Great Britain's[1] independent energy regulator, the Office of Gas and Electricity Markets (Ofgem).[2] According to Ofgem, this market development had the effect of increasing price competition and putting pressure on incumbent suppliers to improve customer service for consumers.[3]

As has been widely reported, the recent energy price volatility (coupled with the price cap limiting suppliers’ ability to pass increased costs on to consumers) has caused a number of energy supply company failures. Yesterday saw the announcement of the collapse of Bulb, one of the UK’s largest energy suppliers, with it being due to be placed into special administration very shortly.

This is the first energy special administration we’ve seen. So how are the insolvency rules different for energy companies? What is a special administration, and why is this the first one?
