Ofgem have published data on the number of customers switching energy suppliers in 2016. 7.7 million gas or electricity switches were done in the UK last year. That is a rise of 26%.
Interestingly the number of switches to small and medium sized companies was 47%. Perhaps a reflection of people’s growing distrust of the bigger companies.
There is still a huge amount of people that can benefit from switching. The 7.7 million figure doesn’t mean 7.7 million households switched. Some people will have switched more than once in a year. Plus many of the switches will be dual fuel customers.
