TTCA Arrangements Companies in Aberdeen: Practical Overview and Selection Guide

This practical guide offers a clear overview of companies in Aberdeen that provide specialist support with TTCA Arrangements as part of their CASS audit services. Rather than ranking them, we present a balanced look at what each company does in the area of Title Transfer Collateral Arrangements and related CASS 5, 6 and 7 compliance.

The companies vary significantly – from larger practices with broad capabilities across multiple sectors to more focused specialists who concentrate on client money and custody asset solutions. Each brings different strengths in helping FCA-regulated companies manage collateral arrangements, ensure proper segregation and controls, and maintain full regulatory compliance.

Whether you need support with TTCA agreements, risk assessments, or ongoing CASS audit requirements, this overview gives you the context to understand your options and make an informed choice.
