  • Ongoing internal audit programme management and reporting

Whether you need support for a single engagement or a fully outsourced internal audit function, we deliver to your exact specifications and timelines.

Why Firms Choose Outsourced Internal Audit

Building and maintaining a full-time internal audit function is expensive. Qualified internal auditors are in short supply. Salaries are rising. And for many mid-size firms the volume of internal audit work does not justify a permanent team.

Outsourced internal audit gives you access to specialist expertise exactly when you need it without the fixed cost of a permanent function. You get qualified internal audit professionals with cross-industry experience, objective and independent assessment of your control environment, and scalable capacity that adjusts to your workload.

The advantages of outsourcing internal audit include:

  • Access to specialist internal audit expertise without permanent hiring costs
  • Objective and independent perspective on your control environment
  • Scalable capacity more support during busy periods, less when work is light
  • Faster deployment than building an in-house team from scratch
  • Significant cost savings compared to equivalent permanent internal audit hires
  • Consistent methodology and quality across all engagements

How Our Internal Audit Consulting Works in Practice

We do not operate as an arms-length consultant who delivers a report and disappears. We work as an integrated part of your team attending planning meetings, communicating directly with process owners and delivering work that reflects a deep understanding of your organisation.

We work with your management team to define the scope, objectives and timeline for each internal audit engagement. Every engagement starts with a clear brief so expectations are aligned from day one.

We identify the highest risk areas of your business and build an audit plan focused on what matters most. Our risk assessment considers your industry, regulatory environment, historical findings and management priorities.

Our team conducts control testing, process walkthroughs and substantive procedures.

We prepare a clear structured internal audit report with findings, risk ratings and practical recommendations your management team can act on. Reports are written to be understood by non-technical stakeholders not just auditors.

We track management responses to findings and follow up on remediation commitments to ensure every issue is properly closed out. We do not consider an engagement complete until findings are resolved.
