CASS 7 Audit Firms in Glasgow: Companies and Services Guide

Choosing a CASS 7 audit provider in Glasgow is more than a routine compliance step. For FCA-regulated firms that hold or control client money, the audit can affect how confidently they manage segregation, reconciliations, records, and wider client asset controls.

Glasgow is served by a mix of audit and assurance firms, from larger professional services networks to specialist practices working with financial services businesses. Each firm may bring different experience in CASS reporting, regulatory assurance, control testing, and support for firms subject to the FCA’s Client Assets Sourcebook.

This guide highlights a selection of CASS 7 audit companies operating in Glasgow. Rather than ranking providers, the aim is to offer practical context – outlining who these firms are, the types of regulated businesses they typically support, and the areas where their audit and assurance work is most relevant.

Acumon

Acumon is a UK firm of chartered accountants and registered auditors providing CASS 7 audit services to FCA-regulated investment firms. The firm works with organisations ranging from growing owner-managed businesses through to larger corporate groups and regulated entities in the investment management sector.

CASS audit engagements are delivered in accordance with relevant FCA requirements and supported by a structured risk-based audit methodology. Acumon provides services in Glasgow as well as across the UK.

Acumon holds relevant regulatory authorisations through its ICAEW registration and FRC status, allowing the firm to undertake specialist CASS audits for firms subject to enhanced regulatory oversight in the United Kingdom. CASS audits are subject to additional regulatory supervision and quality requirements.

In addition to its UK audit registration, Acumon also holds audit licences in several international financial centres, including the Cayman Islands, British Virgin Islands (BVI), Jersey, and Isle of Man. These licences enable the firm to support international corporate groups where entities are located across multiple jurisdictions.

International group structures frequently involve a combination of UK operating companies and offshore holding entities, particularly in sectors such as investment management. Coordinating CASS audit work across these structures requires familiarity with cross-border client asset requirements and related processes.

Acumon works with finance teams and boards to support CASS 7 audit requirements while also helping organisations strengthen client asset protection processes, governance arrangements, and internal controls as they grow.

These include:

  • FCA-regulated investment firms holding client assets
  • Firms providing custody services
  • Investment management businesses

  • Regulated entities subject to FCA Client Assets Sourcebook requirements

CASS audit engagements are typically led by senior audit professionals with direct involvement throughout the engagement.

  • British Virgin Islands audit licence

These registrations allow the firm to provide audit services to groups that include entities in both the UK and key international financial centres.

Acumon works with businesses that are:

  • Approaching their first statutory audit
  • Preparing for external investment
  • Expanding into international markets
  • Operating within corporate group structures

Early engagement with an audit firm can help ensure that financial reporting systems and documentation are aligned with statutory audit requirements.

Conclusion

Choosing a CASS 7 audit provider usually comes down to more than location. Glasgow-based firms may prefer a provider with a local office or Scottish presence, but the more important point is whether the audit team understands FCA-regulated businesses, client money rules, reconciliations, segregation, CASS resolution packs, and the systems behind those controls.

A good fit will usually depend on the firm’s size, business model, CASS footprint, and level of internal compliance support. Some organisations may need a large audit and assurance team with broader regulatory resources. Others may be better suited to a more focused firm that can provide direct communication and a practical review of client money processes.

This guide is not intended to rank CASS 7 audit companies in Glasgow. Its purpose is to give businesses a clearer starting point when comparing providers, reviewing their CASS experience, and deciding which firm is most relevant to their own regulatory and operational needs.
