Is there a time limit for making a complaint?

Yes.

Any complaint made to FDRS must be about an issue or action that took place after a financial service provider joined FDRS, or another scheme (sometimes a provider will move schemes).

A consumer must bring a complaint to FDRS within three months of getting either a decision notice or deadlock notice from their financial servce provider (scheme member)

The complaint must be made to FDRS within two years from when the complaint was first raised with the scheme member

A complaint is not covered by FDRS if it involves events that occurred more than 6 years before the complainant made the complaint to the member
