The issue here is likely to be that you have a CIFAS marker, CIFAS stands for ‘Credit Industry Fraud Avoidance System‘, a not-for-profit fraud prevention membership organisation. It operates as a fraud prevention service, and manages the largest database of fraudulent conduct instances in the UK. Membership of the organisation encompasses a wide range of sectors, with members sharing their data with the aim of reducing fraud and crime. Most financial institutions are members of the CIFAS, and through it they share large amounts of data about companies and individuals.
CIFAS markers are adverse judgements through which one institution, be it a bank, loan company or an insurer, for example, can warn another about risks associated with a potential customer.
There is a range of markers that may appear on your file though the most likely is that for Misuse of Facility: this is where an account or other facility is obtained, with the deliberate intent of using that facility for a fraudulent purpose. This can remain on your file for up to six years.
They can however be removed. the steps are as follows:
Step 1: Request a CIFAS letter
Make a Direct Subject Access Request (DSAR) to CIFAS, requesting a letter setting out the details of the marker(s) that they hold on their database.
This can often be a relatively small amount of information, and the institution that supplied it is not required to provide the evidence this was based on.
Step 2: Contact the institution that issued the marker and request removal
Once the CIFAS letter has been received, you can then contact the institution that issued your marker to request further information before asking for the marker to be removed.
Step 3: Request CIFAS review
If the institution turns down your request for the marker to be removed, you can then request a review directly with the CIFAS, provided that a final response letter has been issued by the institution.
CIFAS are required to adjudicate on the matter within 14 days.
Step 4: Complain to the relevant ombudsman or complaint service
If CIFAS uphold the institution’s decision and refuse to remove the marker, it’s possible to raise a complaint with the relevant ombudsman for the institution that put the marker in place.
If, for example, it was a bank, then the Financial Ombudsman would be the relevant authority to contact.
If it was a mobile phone company, the relevant ombudsman would be the Communications and Internet Services Adjudication Scheme (CISAS).
