Switching

As co-regulator of the Gas industry (in partnership with Government), it’s our responsibility to help facilitate a safe, efficient, reliable, fair and sustainable gas market.

Data plays a central role in our ability to monitor current gas market conditions. We collect information about the gas industry and display it as a resource for both industry and consumers, and use it to guide our extensive ongoing work programmes schedule.

Tracking market performance

Switching metrics are a key data set for us. The ability of consumers to ‘switch’ gas retailers is crucial. It enables consumers to choose and alternate efficiently between competing retailers, which is indicative of a healthy marketplace. The chart below shows the number of consumers per month that switched between retailers since 2010.

The information in these charts is sourced from the Gas Registry and shows statistics on retailer switching and retailer, distributor and meter owner market shares.

An Installation Control Point, or ICP, is a physical point of connection between a gas network and a consumer’s installation. Each ICP has an individual ICP number in the Gas Registry.

Historical registry data and switching statistics can be downloaded in the Registry data spreadsheet.

Consumer switches per month

The ability to switch gas retailers is important to enable consumers to choose, and alternate, efficiently between competing retailers. The below chart shows the number of consumers per month that switched between retailers since 2010.

Please note: The dip in consumer switching in April 2020 reflects COVID‑19 restrictions. The two spikes in consumer switching observed in March 2025 and April 2026 are explained by the consolidation of gas retailer brands, with Frank Energy customers transferred to Genesis Energy (March 2025) and MegaTEL customers transferred to Nova Energy (April 2026).

Tracking efficiency and accessibility

The amount of time it takes for a consumer to be switched over to a new retailer is a determining factor in how accessible and efficient the switching rules are. This chart shows how long on average a switch took to be completed.

Length of time for switch completion
