FRC Minimum Standard for FTSE 350 audit committees

The UK FRC's minimum standard for audit committees took effect in 2025. Audit committees need to show more rigorous oversight of financial reporting and external audit quality. If you are on a UK audit committee, review the guidance and update your practices.

The UK Financial Reporting Council’s (FRC) Audit Committee Minimum Standard becomes fully effective for FTSE 350 companies from 1 January 2025, following a transition period that began with reporting years starting on or after 1 January 2024. The standard, derived from the Government’s 2022 Restoring Trust in Audit and Corporate Governance White Paper, codifies expectations for audit committee oversight of external auditors, financial reporting, internal controls, and transparent communications with shareholders. Boards must evidence that audit committees have refreshed charters, documented tendering strategies, engaged robustly with teams (while honoring universal opt-out rights), and established evidence repositories capable of supporting both FRC supervision and potential transition to the future Audit, Reporting and Governance Authority (ARGA).

The Minimum Standard applies to FTSE 350 premium listed companies, with strong encouragement for other public interest entities to adopt voluntarily. It covers five pillars: audit committee responsibilities, tendering and auditor appointment, oversight of the external audit, reporting and transparency, and access to resources.

Audit committees must show that they challenge management, assess auditor independence, oversee audit plans, monitor audit quality indicators, and maintain effective dialog with shareholders and other teams. The FRC has signaled that it will publish compliance observations and may intervene where audit committees fall short, emphasizing the need for rigorous governance frameworks ahead of the 2025 effective date.

Governance design: Boards should confirm that audit committee terms of reference explicitly incorporate the Minimum Standard’s clauses. This includes assigning responsibility for recommending auditor appointment, approving the audit scope and materiality, reviewing auditor independence safeguards, and assessing the effectiveness of financial reporting controls. Audit committees should schedule deep-dive sessions on risk of material misstatement, fraud risk, climate-related reporting judgments, and sustainability metrics that flow into annual reports. Integration with broader governance frameworks—such as the UK Corporate Governance Code revisions and the forthcoming UK internal controls statement—is essential to avoid siloed oversight.

Membership composition must support independence and expertise requirements. The standard expects at least one member to have recent and relevant financial experience, with collective competence in accounting and auditing. Audit committees should conduct skills assessments, identify gaps (for example, sustainability reporting, digital assurance, cyber risk), and commission training or appoint advisers. Succession planning should ensure continuity when members rotate off, with the nomination committee coordinating recruitment to maintain diversity and expertise.

Oversight of the external audit: Audit committees must provide transparent oversight of auditor performance. They should evaluate the audit strategy, materiality thresholds, use of specialists, and responsiveness to prior-year issues. The Minimum Standard requires committees to assess audit quality indicators, drawing on the FRC’s Audit Quality Inspection findings, firm transparency reports, and internal performance metrics. Committees should document challenge to management judgments, including revenue recognition, impairment, provisioning, and climate-related assumptions. They must also monitor auditor independence, reviewing fee ratios, non-audit service approvals, and partner rotation plans in line with the EU Audit Regulation and FRC Ethical Standard.

Tendering remains a critical element. FTSE 350 companies must tender the external audit at least every 10 years and rotate auditors every 20 years (with limited exceptions). Audit committees should maintain a tendering roadmap that tracks deadlines, pre-market engagement, bidder evaluations, and independence considerations. Evidence should include request-for-proposal (RFP) documentation, evaluation matrices, decision rationales, and shareholder communication materials. Where the audit committee proposes reappointing the incumbent auditor, it should document the rationale, quality improvements, and stakeholder feedback.

Universal opt-out and stakeholder engagement: The Minimum Standard emphasizes constructive communication with shareholders, investors, employees, and other teams about audit matters. Audit committees should ensure that digital channels—investor portals, webcast platforms, email alerts—respect universal opt-out signals such as global privacy control (GPC) headers and unsubscribe requests under UK Privacy and Electronic Communications Regulations (PECR) and international equivalents. When distributing audit committee reports, tender updates, or investor surveys, systems must automatically suppress contacts who have opted out of non-mandatory communications, while preserving mandatory disclosures through regulatory channels such as the London Stock Exchange’s Regulatory News Service (RNS).

Stakeholder engagement plans should include structured dialogs with major shareholders, proxy advisers, employee forums, and sustainability teams. Documentation should record key themes, committee responses, and follow-up actions. Audit committees should also ensure that whistleblowing mechanisms allow employees and third parties to raise concerns anonymously, with opt-out controls preventing marketing follow-up to whistleblowers or other sensitive teams.

Evidence and transparency: The FRC expects audit committees to produce full annual reports describing significant issues considered, how they addressed them, and how auditor independence was safeguarded. Companies should establish an evidence vault that stores committee agendas, papers, meeting minutes, challenge logs, tender records, auditor communications, and stakeholder feedback. This repository should integrate with document management systems, enforce role-based access, and maintain version control. Evidence should be tagged to align with annual report disclosures, enabling rapid retrieval for FRC reviews, investor inquiries, or litigation discovery.

Audit committees should develop dashboards that track key metrics: audit quality indicators (AQIs), control deficiencies, remediation progress, fraud risk assessments, climate reporting judgments, and stakeholder engagement outcomes. These dashboards can support continuous monitoring and help conversations with internal audit, risk committees, and the board. Internal audit should assess the effectiveness of audit committee governance at least once during the 2024–2025 transition, verifying adherence to the Minimum Standard and validating evidence retention.

Integration with reporting frameworks: The Minimum Standard intersects with other UK regulatory developments. The FRC’s 2023 Minimum Standard for Audit Committees sits alongside the UK Corporate Governance Code revisions proposed for 2025, which include stronger internal controls statements and audit and assurance policies (AAPs). Audit committees should align their oversight with these developments, ensuring that assurance plans cover financial statements, sustainability disclosures, and emerging areas such as cyber resilience. They must also coordinate with the UK’s resilience statement and distributable profits disclosure proposals to maintain consistent messaging.

Audit committees should oversee management’s production of an Audit and Assurance Policy, where applicable, outlining which parts of the annual report will receive assurance and how stakeholder feedback informs assurance scope. Universal opt-out controls should extend to AAP consultations, ensuring that investors receiving surveys or invitations can easily decline future outreach. Evidence of consultation outcomes, stakeholder demographics, and opt-out rates should be stored alongside the AAP to show responsiveness.

Action plan for 2024: Refresh audit committee charters; update tendering roadmaps; perform skills assessments; implement universal opt-out compliant communication platforms; build evidence repositories; schedule training on the Minimum Standard, fraud risk, and sustainability reporting; coordinate with internal audit for a readiness review; and prepare improved audit committee reporting for the 2024 annual report cycle. Boards should request assurance that tender documentation, auditor independence assessments, and stakeholder engagement logs are complete and accessible.

Industry engagement through working groups, standards bodies, and peer networks provides early insight into emerging expectations and good practices. Active participation can influence outcomes and ensure organizational interests are considered in future developments.

Competency assessment documentation

FRC's minimum standard requires documented assessment of audit committee member competencies. Develop competency frameworks aligned with FRC expectations, conduct periodic assessments, and document training activities addressing identified gaps.

External auditor oversight

Audit committees must show effective oversight of external auditors. Document auditor appointment processes, fee negotiations, audit plan reviews, and quality assessments. Maintain evidence of committee challenge and auditor responsiveness.
