Assurance engagements rely on public trust. That trust depends on the practitioner behaving ethically and remaining independent. This chapter introduces the ICAEW Code of Ethics, explains why independence matters, and explores the common threats and safeguards practitioners must be aware of.
By the end of this chapter, you will be able to:
Assurance is more than technical checking — it is about credibility. If practitioners are not trusted to act ethically, their conclusions lose value.
Ethics in context:
The ICAEW Code (based on the IESBA Code) applies to all ICAEW members, students, and firms. It sets out five fundamental principles:
Failure to follow these principles can lead to disciplinary action and loss of trust.
Independence means being free from relationships or influences that compromise — or appear to compromise — objectivity.
Example:
If an auditor owns shares in the company being audited, independence is compromised in fact. If the auditor's close relative works as finance director, independence in appearance is compromised.
Common threats include:
When threats exist, practitioners must apply safeguards to reduce them to an acceptable level.
Examples:
If no adequate safeguard exists → decline or resign from the engagement.
Confidentiality extends to all client information. Practitioners must not disclose information without proper authority unless legally required (e.g. money laundering reporting).
With the rise of GDPR and data protection laws, auditors must also ensure that client data is handled securely, including electronic records and personal information.
Ethics are supported by regulatory frameworks:
1. What are the five fundamental principles of the ICAEW Code of Ethics?
2. What is the difference between independence in fact and independence in appearance?
3. Give one example each of a self-interest threat and a familiarity threat.
4. What should an auditor do if no safeguard can reduce a threat to independence?
