More information

At-a-glance summary

The number of domestic gas and electricity switches generally follows a seasonal pattern (with peaks around March and November then dipping in January and the summer months). Switching has been on the rise since 2014. The number of domestic switches in the 12 months up to June 2019 was 11% higher than in the 12 months up to June 2018 for electricity and 8% higher for gas.  

There has been a break in the usual seasonal switching pattern with the number of switches staying at a relatively constant level for each month since February 2018 instead of falling in the summer months, as we have historically seen. Switching hit historic highs in 2019, with the number of electricity and gas switches reaching a record high in April, before falling off in May, and a further drop in June.

In June 2019 the proportion of net gains in switching away from the six largest suppliers made up 19% of total switches for gas and electricity combined, significantly down from 48% in June 2018.

Relevance and further information

External switching, from one supplier to another, is one measure of consumer engagement with the market. The number of switches to small and medium sized suppliers show how these suppliers are attracting customers over time. For summary information on the switching figures for the year please see also the facts and figures.

Methodology

The number of customers switching supplier shown in the graph is based on the number of meter points a supplier gains from another following a customer choice to change their supplier.

The net gains for small and medium suppliers is calculated by subtracting from the gross meter point gains these suppliers achieve over the month the gross number of meter points these suppliers lose over the same period.

As of July 2017, supply points connected to independent gas transporters are included in the gas data provided by Xoserve.
