Information correct as of: August 2020

This graph shows the percentage of complaints resolved by the six largest energy suppliers by the end of the next day from when a complaint was reported over the period Q1 2013 to Q2 2020.

In January 2020, OVO completed the acquisition of SSE’s domestic business and kept SSE as a separate white label brand. As a result, we have moved OVO from the group of medium-sized suppliers to that of the six largest as of Q1 2020. SSE’s complaints are now being reported under its parent OVO as of Q1 2020.
