AI Governance for
Accounting Firms
The PPCS AI Governance Assurance Standard (AIGAS) — a structured, practical framework helping UK accounting firms adopt Artificial Intelligence responsibly.
AI Is Already Inside Your Practice
Artificial Intelligence is rapidly becoming embedded within modern accounting practices. Tools such as ChatGPT, Microsoft Copilot and AI features integrated into accounting platforms are already being used across firms of all sizes.
However, as AI adoption increases, so do governance responsibilities. Firms must begin asking the right questions — before problems arise.
- Draft communications
- Summarise documents
- Assist with research
- Analyse information
- Improve productivity across internal workflows
Is Your Firm Asking the Right Questions?
Accounting firms must consider governance before AI risks become liabilities.
The PPCS AI Governance Assurance Standard (AIGAS) has been developed to provide accounting firms with a practical framework for implementing responsible AI governance.
What Is the AIGAS Framework?
The PPCS AI Governance Assurance Standard (AIGAS) is a structured governance framework designed specifically for UK accounting firms adopting Artificial Intelligence tools.
Independent Review
The framework provides an independent governance review confirming appropriate safeguards are in place.
Responsible
Demonstrates that your use of AI is responsible, risk-aware and professionally accountable.
Sector Specific
AIGAS focuses specifically on governance challenges faced by accountants — not general IT or cybersecurity.
Properly Controlled
Confirms that governance controls are documented and actively implemented within the firm.
Why AI Governance Matters for Accountants
Artificial Intelligence can significantly improve efficiency within accounting firms, but it also introduces new forms of risk. Understanding these risks is the first step toward managing them.
Incorrect or Hallucinated Outputs
Generative AI systems can produce responses that appear credible but contain factual errors. Without appropriate review processes, incorrect outputs could influence professional advice.
Confidentiality and Data Protection Risks
Entering identifiable client data into external AI tools could create confidentiality risks or potential data protection concerns. Accounting firms must understand how AI providers process and store submitted information.
Professional Liability
Professional indemnity insurers increasingly expect firms to demonstrate governance around emerging technologies. Failure to manage AI risks appropriately may expose firms to liability.
Regulatory Scrutiny
Regulators and professional bodies are increasingly examining how firms adopt AI technologies and manage associated risks. Documented governance frameworks help demonstrate responsible adoption.
The AIGAS Governance Framework
The PPCS AIGAS framework is structured around six core governance pillars. These pillars reflect recognised governance principles while remaining practical for accounting firms.
AI Strategy and Purpose
Firms should clearly understand how and why AI tools are used within the practice. This includes maintaining a register of AI tools and documenting their purpose.
- AI tool register
- Documented purpose for each tool
- Formal AI strategy statements (advanced)
- Acceptable use guidelines
Risk and Compliance
AI introduces operational and regulatory risks that should be identified and managed, including incorrect outputs, automation over-reliance, confidentiality exposure and regulatory implications.
- Structured risk assessments
- AI risk registers
- Regulatory risk identification
Data Protection and Confidentiality
Accounting firms handle highly sensitive client information. The framework requires safeguards governing how client data interacts with AI systems.
- Restrictions on entering confidential data into public AI tools
- Review of AI provider data handling practices
- Data protection impact screening where appropriate
Governance and Accountability
Responsible technology adoption requires clear oversight. Firms implementing the framework designate an individual responsible for AI governance. Larger firms may also establish periodic governance reviews.
Operational Controls
Artificial Intelligence should assist professional work rather than replace professional judgement. AI-generated outputs should be reviewed by qualified individuals before being relied upon in client advice.
- Human review before client advice
- Procedures for correcting AI errors
Monitoring and Continuous Improvement
AI technologies evolve rapidly. Firms should periodically review AI usage and governance controls to ensure they remain appropriate. Annual governance reviews form part of the AIGAS assurance process.
The AIGAS Tier Model
The framework provides a progressive governance pathway from foundational controls through to internationally recognised certification.
Bronze and Silver are part of the PPCS AIGAS framework. ISO/IEC 42001 certification is conducted by accredited certification bodies. AIGAS™ may serve as a practical preparatory step toward ISO-level governance where appropriate.

The AIGAS Assurance Process
Assurance is granted following a structured evidence review conducted by PPCS. Assurance remains valid for 12 months, after which reassessment is required.
Initial Review
Initial review of the firm's AI usage and governance documentation.
Governance Assessment
Governance assessment against AIGAS framework requirements.
Evidence Review
Evidence review to confirm implementation of required controls.
Assurance Decision
Assurance decision where governance controls are confirmed and certification issued.
What AIGAS Is — and Is Not
AIGAS provides independent governance assurance. We believe in complete transparency about what the standard covers and where its boundaries lie.
✔ AIGAS Does
- Confirms the presence of documented AI governance controls
- Demonstrates responsible AI adoption
✘ AIGAS Does Not
- Is not ISO certification
- Is not an accredited certification scheme
- Does not replace regulatory compliance obligations
ISO/IEC 42001 certification must be conducted through accredited certification bodies. PPCS provides readiness and preparatory guidance for firms pursuing this pathway.
