Tandem Bank
If Tandem Bank has filed or may have filed a CIFAS marker after an account review, application, transaction dispute, payment investigation, or product closure, this page explains how the filing can be challenged using your CIFAS report, Tandem Bank records, supporting evidence, and the correct escalation route.
Tandem Bank
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.

In a Tandem Bank case, the marker may relate to:
The key point is simple. Tandem Bank must be able to justify the marker with evidence, not suspicion, assumption, or a general account concern.
Tandem Bank
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:
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.
Tandem Bank
If you don't have the time to navigate the complaints process or analyse complex DSAR files, our specialist team can review your case. We draft bespoke, evidence-backed appeal packages designed to meet CIFAS Principle 4 standards.
Tandem Bank
A Tandem Bank CIFAS marker removal complaint should follow a clear process. The mistake most people make is sending a general complaint before they have the CIFAS report, issuer records, and supporting evidence in order.
Do not send a generic, emotional complaint to Tandem Bank. You must follow a structured, evidence-led escalation process.
The process usually works like this:
Bookmark this page or share it with anyone helping you. The aim is simple: get the record, build the evidence, submit the complaint properly, and escalate if Tandem Bank does not remove the marker.
Tandem Bank
Before a Tandem Bank CIFAS marker can be complained about properly, you need the records. The CIFAS DSAR shows what has been filed on the National Fraud Database. The Tandem Bank DSAR helps identify what evidence the issuer relied on when the marker was filed.
You should request:
The DSAR stage matters because it stops the complaint being based on guesswork. Once the records arrive, the marker can be reviewed against the category used, the evidence held, and whether the filing can be justified under CIFAS and data protection principles.
Tandem Bank
To prepare a strong Tandem Bank complaint, the evidence needs to show what happened, why the marker is disputed, and what impact it has had. You do not need to write the complaint yourself. The job at this stage is to upload the right information so the complaint can be built properly.
Upload anything you have, including:
The more complete the upload, the stronger the complaint can be. We use the records to identify the marker category, the evidence problem, the data protection issues, and the practical impact of the marker before preparing the documents.
Tandem Bank
The Tandem Bank complaint letter should not be a generic removal request. It should be built around the CIFAS category, the issuer records, the evidence, and the reason the marker should not remain.
We prepare a structured complaint package that can include:
The complaint is designed to make Tandem Bank address the core issue: whether the marker is supported by clear evidence, the correct category, and a lawful basis for continued processing. If the evidence does not justify the marker, the complaint should ask for removal, correction, or restriction.
Tandem Bank
Once your complaint package is ready, we send you a ready-to-send email for Tandem Bank or the current trading entity responsible for the account. Where verified contact information is available, we include it with the complaint. If a direct complaint contact is not available, we explain how to find the correct firm and complaint details on the FCA Register.

Cifas Removal Support
Tandem Bank must respond within the relevant complaint deadline. Your letter must be strictly factual, evidence-led, and tied to the CIFAS category and data protection issues. If you are unsure how to structure your evidence, we can prepare a bespoke Tandem Bank complaint letter for you.
The ready-to-send complaint email can include:
After the complaint is submitted, Tandem Bank should acknowledge the complaint and investigate the issues raised. The issuer will usually have up to 8 weeks to provide a Final Response Letter.
As a subscriber, you also get access to our weekly CIFAS Removal Workshops and AI assistant support. This helps you understand replies from Tandem Bank, respond carefully to requests for more information, and avoid making mistakes that could weaken the complaint.
Tandem Bank
After your complaint is submitted, Tandem Bank should investigate the marker, review the evidence, and explain whether it will remove, correct, restrict, or maintain the CIFAS filing.
The Final Response Letter should explain:
Do not treat a refusal as the end of the process. The Final Response Letter is an important document because it shows the reasons Tandem Bank is relying on. If the marker is not removed, upload the Final Response Letter to your case file so the next stage can be reviewed and prepared.
Tandem Bank
If Tandem Bank refuses to remove the marker, upload the Final Response Letter to your case file. Once we have reviewed the response, we prepare the documents needed to escalate the complaint to the Financial Ombudsman Service and CIFAS.
We prepare the Ombudsman complaint so you can register the dispute without starting again from scratch. In most cases, you simply forward the prepared email and documents to the Financial Ombudsman Service.
We prepare:
The Financial Ombudsman Service reviews whether Tandem Bank acted fairly and reasonably. It may consider the evidence relied on by the issuer, your explanation, complaint handling, supporting documents, and whether maintaining the marker is fair.
Financial Ombudsman Representation
The Ombudsman will review the case completely afresh. To maximise your chances, your submission must clearly highlight how Tandem Bank failed to meet the Standard of Proof. Learn how our FOS Escalation Service handles the legal jargon for you.
We also prepare the information needed for the CIFAS online complaints form. This helps keep the CIFAS review focused on the marker category, the evidence, and whether the filing meets the standards required for the National Fraud Database.
We prepare:
CIFAS reviews whether the marker meets the standards required for inclusion on the National Fraud Database. It may consider the category used, the information supplied by Tandem Bank, whether CIFAS principles were followed, and whether the issuer has justified keeping the marker in place.
Tandem Bank
A Tandem Bank CIFAS marker complaint can have different outcomes depending on the evidence, the category used, and how Tandem Bank responds to the complaint.
Possible outcomes include:
The goal is to make Tandem Bank justify the marker properly. If the evidence does not support the CIFAS category, or if the marker is inaccurate, unfair, or disproportionate, removal or correction should be requested.
If compensation is awarded by the Financial Ombudsman Service, it is paid directly to you. We do not charge a success fee and we do not take a percentage of any compensation awarded.

Issuer questions
A Tandem Bank CIFAS marker is a fraud-risk record connected to accounts, payments, onboarding, lending, or account review records. It may affect banking, credit, mortgage applications, employment screening, and other financial services.
Yes. A Tandem Bank CIFAS marker can be removed if the filing cannot be properly justified. The complaint needs to address the evidence, the marker category, and whether the marker is accurate, fair, and lawful under data protection principles.
Start by requesting your CIFAS DSAR and gathering any records you have from Tandem Bank. Then upload your CIFAS report, issuer records, supporting evidence, and a short explanation of what happened so the complaint package can be prepared.
Useful evidence may include your CIFAS report, Tandem Bank DSAR response, account or product records, correspondence, screenshots, transaction records, fraud reports, refusal letters, and evidence showing the impact of the marker.
After the complaint is submitted, Tandem Bank will usually have up to 8 weeks to investigate and issue a Final Response Letter. If no proper final response is received, or if the marker is maintained, the case may be ready for escalation.
If Tandem Bank refuses removal, upload the Final Response Letter to your case file. We can then prepare the Financial Ombudsman complaint documents and CIFAS review responses so the matter can be escalated.
The Financial Ombudsman Service can require an issuer to remove or correct a marker where it decides the firm acted unfairly or unreasonably. It may also award compensation where appropriate.
CIFAS can review whether the marker meets the standards required for inclusion on the National Fraud Database. If the filing is not properly justified, CIFAS may require the issuer to amend or remove it.
No. Once you upload your CIFAS report, Tandem Bank records, and supporting evidence, we prepare the complaint letter, evidence summary, removal request, and escalation roadmap for you.
No. If compensation is awarded by the Financial Ombudsman Service or another route, it is paid directly to you. We do not charge a success fee and we do not take a percentage of your compensation.
