The FOS said it would publish the vast majority of final decisions on its new site, as part of its drive to increase transparency in its decision making.
The only decisions that will not go on the site will be where there is a likelihood that complainants are identified, which is prohibited by law.
So far, the service has listed 1,253 decisions, of which around a quarter were upheld.
Data will be added on a rolling basis, with a six to nine week delay to give consumers the chance to accept the decision – no details will be published before the consumer has officially accepted.
The FOS said: “We are making things more transparent for our customers, which are consumers and businesses, so that they can better understand our approach and how we handle complaints.”
The FOS is required to publish final decisions under the Financial Services and Markets Act 2000, as amended by the Financial Services Act 2012.
