Pensions Ombudsman
The Pensions Ombudsman may investigate and determine any complaint or dispute over the way in which a pension arrangement is run. Normally the Ombudsman will require you to have been through the Scheme's procedure for resolving disputes and will ask TPAS to consider the complaint first.
