According to January 2020’s switching data published by ElectraLink today, 457,000 changes of supplier were completed last month. This is an 18.6% increase on January 2019 and is the first January since records began that has crossed the 400,000 switches completed mark.

Switching activity tends to be lower early in the year, but January’s figures have set 2020 off to an impressive start. Could 2020 be yet another record year for switching activity?

Switches started reached 670,000 last month, 19.8% higher than the same time last year.

In terms of switching types, challengers continue to attract customers away from the Big Six. However, as was the trend towards the end of 2019, the Big Six are now losing fewer customers to challengers than before:

  • Big Six to challenger switches reached 158,000 – 2.8% more than January 2019 and 34.7% of January 2020’s total switches completed,
  • Big Six to Big Six switches hit 124,000 – 47.3% more than January 2019 and 27.2% of January 2020’s total switches completed,
  • Challenger to Big Six switches landed at 72,000 – 55.6% more than January 2019 and 15.8% of January 2020’s total switches completed, and
  • Challenger to challenger switches hit 102,000 – 1.7% more than January 2019 and 22.3% of January 2020’s total switches completed.

The above figures relate to electricity switching in Great Britain only.

We do not include switches from Supplier of Last Resort (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.

Switches started refers to the number of valid switches started, also known as switches raised.
