Citizens Advice published its latest figures, for the period of January to March 2016, which show that the utility giant had a complaints score of 28.4 per 100,000 customers.
In comparison, the worst performer in the market had around 60 times more complaints than SSE – one of Britain’s ‘Big Six’ energy providers.
Prior to last quarter, when SSE came second by 0.4 points, SSE had held the number one spot every quarter since Citizens Advice started the report in 2009.
The scores are based on complaints made to third parties and are therefore a highly reliable measure of customer service. In comparison to the self-reported numbers companies provide to OFGEM every three months, these results give an unbiased, independent view of complaint handling.
