CIFAS and SIRA markers are both fraud prevention tools used across the UK’s financial services sector. They are used in separate databases, however, and are managed by different organisations and operate under different rules. Both can cause severe disruption in situations where the affected individual attempts to obtain insurance, banking products or credit. This article explains the key differences, how each marker is placed and how to challenge them individually.
A CIFAS marker is a fraud indicator used by the National Fraud Database, which is managed by the UK’s leading fraud prevention service – CIFAS. CIFAS is a not-for-profit membership organisation whose members include banks, insurers, lenders and other financial organisations. When a member identifies or suspects that an individual has committed or attempted to commit fraud, it may file a marker against that person.
A SIRA marker, by contrast, is used by the National SIRA database, operated by Synectics Solutions. This is a commercial data analytics company which originally focused on the insurance sector but has now been expanding across other financial services. When a member organisation suspects an individual has been involved in fraud, it may record a marker on the database. Unlike CIFAS, Synectics Solutions acts as a data processor rather than a data controller, holding the data on behalf of the member organisation that has placed the marker.
Both types of markers serve as fraud warnings shared across a network of organisations. However, they differ in important ways, including who manages the database, the standards applied before a marker is placed and the routes available for challenging them.
Although both markers flag an individual as a potential fraud risk, there are several practical differences that are important to understand:
Challenging these markers is possible, but there are common errors that frequently undermine any efforts to do so:
At Gherson, we regularly advise clients affected by markers on the CIFAS National Fraud Database or the National SIRA database. Many markers are placed without adequate justification or a giving the affected individual a fair opportunity to respond. We have successfully secured the removal of markers from both databases by engaging with CIFAS, Synectics Solutions and originating member organisations.
If you suspect you may have a CIFAS or SIRA marker against you, obtaining legal advice as early as possible is paramount. Understanding which database holds the marker and what rights are available is critical to mounting an effective challenge.
Yes. The two databases are entirely separate, and it is possible to have both markers simultaneously. This can happen when multiple organisations in different sectors flag the same individual. Each marker must be investigated and challenged independently.
You can submit a Subject Access Request (SAR) to CIFAS and to Synectics Solutions. Under the UK GDPR, both organisations are required to respond within one month and provide you with a copy of any personal data they hold about you. This will confirm whether a marker exists and provide details about the basis on which it has been placed.
No. Neither a CIFAS marker nor a SIRA marker constitute a criminal conviction, a caution or any form of criminal record. Both are private-sector fraud indicators recorded by commercial or not-for-profit organisations based on their own assessments. You do not need to have been investigated, charged or convicted of any criminal offence for either type of marker to be placed.
