Energy supplier switching in GB has reached a new high since changes of supplier (CoS) collapsed in late 2021. Households and SMEs completed 176,000 switches in March 2023 – a 64 per cent increase compared to March 2022 and 18 per cent more than February 2023.
March 2023 now stands as the month with the most switches since November 2021 when dozens of suppliers went out of business and the domestic energy crisis became of public concern. It overshoots the 149,000 CoS completed in October 2022.
There have been 443,000 voluntary CoS in 2023 so far.
The largest change to switching types occurred in CoS between Large suppliers. Large-to-Large switches increased above the overall 18 per cent switching increase for the month, while Other-to-Other CoS is the only type that decreased compared to February.
- Large to Large switches jumped to 105,000 – 23 per cent more than February 2023 and 59 per cent of March 2023’s total CoS completed,
- Large to Other switches totalled 31,000 – 16 per cent more than February 2023 and 18 per cent of March 2023’s total CoS completed,
- Other to Large switches reached 32,000 – 13 per cent more than February 2023 and 18 per cent of March 2023’s total CoS completed,
- And Other to Other switches landed at 9,000 – four per cent less than February 2023 and five per cent of March 2023’s total CoS completed.

The above figures relate to electricity CoS in Great Britain only.
We do not include CoS from SoLR processes or trade sales in our monthly CoS reporting. We account for only voluntary switches, or instances where the customer made an active decision and took action to change supplier, including after a contract expired.
