Processes are in place through which concerns may be raised regarding discharge from the Royal Navy. For non-medical discharges, this is through the Service Complaints or appeal process. For medical discharges, this is via a request for review of the Royal Navy Medical Employability Board decision, as well as an independent appeal process. All recourse to appeal is time limited.
In addition, the Veterans Welfare Services, part of the Ministry of Defence Veterans UK organisation, provides one-to-one support to veterans through a national network of welfare managers. This service can be accessed online at https://www.gov.uk/guidance/veterans-welfare-service
