More information

At-a-glance-summary

There had been a steady increase in the number of licensed 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 eight suppliers left the market. During 2019, eight suppliers entered and twelve suppliers exited the market. In the first quarter of 2020, one supplier entered (Omni) and two suppliers exited the market (SSE and Engie).  

In the second quarter of 2020, one supplier, Colorado, entered the market and two suppliers exited. One supplier (GNergy) ceased to trade and we appointed one SoLR (Bulb). During the same period, EDF completed the acquisition of iSupply via a market transaction that was initiated in March 2020.

E.ON acquired npower in January 2020, but the migration of customers is still ongoing and npower’s exit has not yet been recorded for the purpose of this indicator. In September and October 2020, more suppliers left the market. All these exits will be reflected in subsequent updates.

 

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.
