"Even allowing for the change in reporting rules, and some progress made, the numbers are still significant."
Since June 2016, firms have been required to report data in a new way which the FCA says has attributed to the increase in the number of complaints reported.
However despite the changes, Christopher Woolard, Executive Director of Strategy and Competition, said the figures are "still significant".
In the Home Finance category Paragon Finance, Together, Kensington, Pepper, and Charter Court all appeared in the top ten for complaints per 1,000 balances outstanding.
Payment protection insurance continues to be the most complained about product making up a third of all complaints in H1 2017. The total number of PPI complaints increased by 24% from 899,000 to 1.11m.
The total redress paid to consumers was £1.99 billion in the first half of 2017, 82% of which was related to PPI complaints.
43% of all complaints made during the first half of 2017 were related to ‘advising, selling and arranging’, down from 59% in the first half of 2016.
While ‘general administration and customer service’ accounted for 27% of all complaints in the first half of 2016, they now account for 38% of all complaints.
Christopher Woolard, Executive Director of Strategy and Competition, said: “We now require firms to report all complaints which gives us a fuller picture of where the industry might not be meeting customer needs. But even allowing for the change in reporting rules, and some progress made, the numbers are still significant.
“Firms need to do all they can to reduce complaints and ensure that they are working in the best interests of consumers.”
