Overview

What is an internal controls review?

Internal controls are the policies, procedures, approvals, reconciliations and checks that prevent or detect errors, fraud and failures. An internal controls review identifies the key controls in your processes and tests whether they are well designed and actually operate as intended.

For companies applying the UK Corporate Governance Code, it supports the board’s declaration on the effectiveness of material controls. For every organisation, it reduces the risk of financial loss, misstatement and operational failure, and often removes duplicated or low-value controls along the way.

What it stands for

Evidence over assumptionControls are tested, not just described.
Proportionate testingEffort focused on the controls that matter most.

Who it’s for

When you need evidence that controls work

Boards are increasingly expected to show, not just assert, that their controls are effective. A structured controls review gives you that evidence and a clear plan for any gaps.

  • Companies preparing for the Provision 29 material controls declaration
  • Finance teams after a system change, merger or rapid growth
  • Organisations that have suffered errors, losses or fraud
  • Boards wanting assurance over key financial and operational controls

How it works

Map, test and fix your key controls

  1. Stage 1

    Scope

    We identify your key processes and the material risks that matter most to the board.

  2. Stage 2

    Map

    We document processes, risks and controls in a risk and control matrix (RCM).

  3. Stage 3

    Test

    We test design and operating effectiveness, including segregation of duties and system access.

  4. Stage 4

    Remediate

    We agree practical actions to close gaps, then re-test to confirm they work.

Why it matters

Controls only protect you if they work. We prove that they do, or show you how to fix them.

Frequently asked questions

Internal Controls Reviews: your questions

How much does an internal controls review cost?

It depends on the number of processes, entities and controls in scope. We agree a fixed fee once the scope is set.

What is the Provision 29 material controls declaration?

Under the 2024 UK Corporate Governance Code, boards of companies applying the Code must declare whether their material internal controls were effective, for financial years beginning on or after 1 January 2026.

What is a risk and control matrix?

A document that links each key risk in a process to the controls that address it, who owns them and how they are tested.

Is this only for listed companies?

No. Any organisation can benefit from knowing its key controls work, especially after growth, system changes or a loss.

Do you include IT controls?

Our focus is business process and financial controls. Where specialist IT controls testing is needed, we will say so and agree how it is covered.
