FOS running costs rose from £270m to £276m and the FOS had a deficit of £33.5m after tax (£41m in 2018/19).

The report also reveals that the FOS workload has nearly halved from over 500,000 complaints received a year in 2013/14 to 273,000 last year, mostly due to a decline in PPI complaints.

There were 1,558 complaints about Claims Management Companies, a new area for the FOS.

There have been some Covid-19 related complaints, the FOS said, but so far not a “significant” number.
