Energy supply switching in the UK - Statistics & Facts

Switching energy suppliers has become a more ubiquitous practice in the United Kingdom in recent years. State agencies and independent groups like Ofgem and Citizens Advice offer straightforward comparisons of different tariffs and step by step guides on how to complete a switch online. However, recently introduced rules for new entrants to the energy market will likely see the number of switches decline in the coming years.
In 2019, the number of British electricity and gas customers changing their energy suppliers reached a record high. 5.95 million people had adopted a different electricity supplier, up from just 3.06 million in 2014. By comparison, 4.82 million customers had switched their gas provider. According to a survey conducted in 2019, 98 percent of those who switched energy suppliers reported having changed gas and electricity providers at the same time.

In March 2020, 152,833 customers had switched from a large electricity supplier to another company of similar size, while 205,549 customers turned from leading electricity companies to small and mid-tier providers that month. EDF Energy is the market leader among non-domestic electricity customers, holding an 18 percent share of the market for NHH meters with profile classes between five and eight. Among gas customers, 24 percent stated they had changed their provider over the last 12 months, with network operators needing an average of 18 days to complete a supplier change.

Of the differing concerns regarding a change in utilities provider, 30 percent of those who had changed tariffs expressed worry over costs increasing after they had switched.
