The Centre for Public Interest Audit (CPIA) is a policy and research institute formed to improve audit quality across the profession.
Our vision
We believe that increasing trust in UK audit and assurance is key to building confidence in Britain’s capital markets. Driving change requires collective commitment, a willingness to ask the difficult questions and an evidence-based approach to advancing best practice. Our strength is the combination of our collective expertise to challenge the status quo; we are action-oriented, forward-looking and provide objective perspectives on audit quality to drive real change.
We aspire to be the clear driving force behind a resilient and valued audit profession, which demonstrates integrity, transparency and accountability
at its core.
A trusted audit and assurance profession benefits all society: whether through enabling competition and choice by supporting newer PIE auditor entrants to the market, creating innovation through data-led research or by representing PIE audit with a clear voice for the first time. The CPIA will help to build trust in auditing, and confidence in UK plc as a result.
How will we achieve this

Providing evidence-based thought leadership on profession-wide issues

Promoting audit quality, knowledge and education

Supporting best practice in auditing public interest entities (PIEs)
Our focus
We advocate for meaningful reform and recognise the importance of reform in improving audit quality across the profession. Therefore we welcome the announcement in the King’s Speech that a Draft Audit Reform and Corporate Governance Bill will be laid before Parliament in 2025. As a primarily policy and research institute we will provide an expert voice to the Bills’ passage, and beyond, which ensures it supports high quality audit.
Our focus is on engaging with priority stakeholders, including investors, audit chairs, and regulators. Our goal will be to identify areas of shared concern and to advocate for proportionate measures.

2025 Audit Trust Index
We publish the Audit Trust Index annually to measure and track perceptions of audit trust and identify emerging trends and challenges facing the profession. The insights gathered guide our strategic decisions, shape our work plan, and reinforce our commitment to enhancing audit quality and public trust in the UK audit landscape.
