What Is A Tandem Bank CIFAS Marker?

A Tandem Bank CIFAS marker is a fraud-risk record connected to accounts, payments, onboarding, lending, or account review records. It is not a normal credit issue. It is a fraud-risk filing on the National Fraud Database and should be reviewed against the CIFAS category used, the records held by Tandem Bank, and the evidence relied on when the marker was filed.

Research identifies Tandem Bank Limited as the relevant legal entity for Tandem Bank, trading as Tandem / Oplo / Allium Money / GDFC, company number 00955491, FCA reference 204479. Tandem privacy lists group entities and Tandem Bank company number. Tandem FAQ confirms FCA reference 204479. Relevant published Ombudsman or regulator material includes: https://www.financial-ombudsman.org.uk/decision/DRN-5886201.pdf.

In a Tandem Bank case, the marker may relate to:

Account opening information
Transaction monitoring or payment activity
Device, login, or access records
Source of funds or source of wealth questions
Account closure, restriction, or refusal decisions

The key point is simple. Tandem Bank must be able to justify the marker with evidence, not suspicion, assumption, or a general account concern.

Can A Tandem Bank CIFAS Marker Be Removed?

Yes. A Tandem Bank CIFAS marker can be removed if the filing cannot be properly justified. The issue is not simply whether Tandem Bank had concerns. The issue is whether the evidence meets the required standard for a CIFAS marker.

We use the CIFAS Civil Dispute Framework to complain about:

Whether the correct CIFAS category was used
Whether Tandem Bank had clear evidence of deliberate dishonesty
Whether the marker was based on evidence rather than suspicion
Whether innocent explanations, scams, pressure, vulnerability, or third-party involvement were considered
Whether the marker is accurate, fair, and lawful under data protection principles
Whether the marker should be removed, corrected, or restricted

You do not need to guess what to write. Upload your CIFAS report, Tandem Bank records, and supporting evidence. We prepare the complaint documents needed to dispute the marker properly and guide the next stage if Tandem Bank refuses to remove it.

Marker categories

The marker category changes the complaint

A CIFAS marker is not challenged in the abstract. The complaint depends on the category used, the evidence relied on, and whether the issuer can justify that specific filing.
