More information

At-a-glance-summary

There had been a steady increase in the number of suppliers becoming active in the domestic energy markets up to mid-2018. In the second half of 2018, no new domestic suppliers became active, while 8 suppliers left the market. During the first quarter of 2019, three more suppliers exited the market, with only one new entry.

Between July 2018 and December 2018, there were seven exits for which we had to appoint a Supplier of Last Resort (SoLR) to absorb their customers: Iresa, GEN4U, Usio, Snowdrop Energy, Spark Energy, Extra Energy and OneSelect. Another exit occurred in September 2018, when Octopus directly acquired Affect Energy, which has since been operating as a separately licensed brand, fully owned by Octopus.

Between January 2019 and March 2019 three suppliers exited the market through the SoLR process: Economy Energy, Our Power and Brilliant Energy.

Relevance and further information

This chart helps understand the GB energy market dynamics by showing the number of entries and exits that underpins the evolution in the number of active licensed suppliers over time.

For a breakdown of how many active suppliers are supplying each fuel type please go to our chart Number of active suppliers by fuel type.

Methodology

We calculate the number of entries, exits and total number of active licensed suppliers (i.e. those with customers) from the information that both network operators and suppliers provide to us. White label suppliers are not included in this number. White label suppliers are organisations without supply licenses that partner with an active licensed supplier to offer gas and electricity using their own brand.
