More information

At-a-glance summary

There were 60 active suppliers in the domestic gas and electricity retail markets as of March 2019. These consisted of the six large suppliers and 54 other suppliers, mainly active in both gas and electricity.

From December 2018 to March 2019 the number of active domestic suppliers continued to decline.  This was due to only one supplier entering the market and three suppliers exiting during this period. For more detail on market entries and exits see the indicator ‘Supplier entries and exits in the domestic retail energy market’.

Relevance and further information

The number of active suppliers in the GB energy market helps us to understand the dynamics of market concentration over time, as new participants enter; win customers and some existing firms exit the market.

Methodology

We calculate the 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.
