External Audit Services

Our approach to external audit

Audits are fundamental to the success of UK business and capital markets. Our audit clients include privately owned companies, PE-backed businesses, public sector organisations and businesses listed in the UK and internationally. We support our audit clients as they grow and enter new markets.

In the UK we have over 250 audit partners and directors and more than 3,000 dedicated audit staff focused on delivering high quality, robust and transparent audits. As a Tier One regulated firm, we are one of a small number of audit firms equipped to deliver audits for businesses of any size and structure.

BDO's focus is on the mid-market where we choose to work with ambitious, growing businesses that drive the UK economy.

A BDO audit is more than what we do, it’s how we do it.

  • Our partner-led audits are delivered by sector and market specialists - driving valuable insights, advising on market issues, how they will impact the businesses we work with, and connecting our clients to a network of industry leaders
  • We take pride in proactive and transparent communication to our clients. BDO's inclusive culture creates high performing teams who are authentic, curious, collaborative and operate as one
  • We invest time to understand the businesses we work with and develop tailored audits directed at key audit risks
  • BDO commits to excellent delivery, with efficient, well-managed and high-quality audits, underpinned by market leading technology.

Our audits are characterised by independence and professional scepticism. Our audit will be a complete, accurate and fair representation of your financial statements and disclosures that will will enable your business to deliver accurate and transparent reporting to all stakeholders drive long-term value.

Features of audits

Our audit partners and staff are based across our 18 UK offices and our international network includes audit specialists who deliver high quality audits in more than 166 countries internationally. We deliver audits for international groups in collaboration with other BDO member firms while maintaining the same commitment to independence and quality.

The Audit Committee Network is a dedicated programme of roundtable discussions for Chairs of Audit Committees with subject matter experts and topical articles. This community provides open dialogue, learning and mutual support to members to stay ahead in the ever-evolving corporate governance.

These events align with BDO’s wider support for Non Executive Directors, keeping them up to speed with regulatory developments as well as the latest in corporate strategy and governance.

Non-Executive Directors Hub

We issue formal reports at the start and end of the audit process. We also attend all Audit Committee meetings. It is important for our team to be robust and independent of management. If differences in opinion do arise, we will brief your CFO to ensure they understand our views before raising the issue with the Audit Committee.

We provide a private, secure digital portal designed to streamline the exchange of information and communication. The portal acts as a single point of reference for all stored information and helps avoid duplication of effort.

BDO Advantage is our innovative data analytics solution that enables us to provide management, the Board and the Audit Committee with an insightful view of the processes and data within key business cycles. 

We use BDO advantage alongside other technology to assess the data in your financial statements to check for completeness and accuracy, look for outliers and determine which areas require additional audit focus. We will also look for opportunities to apply bespoke data analytics in other areas of your Financial Statement.

We have extensive experience of working with internal audit teams. We will work with your internal auditors to obtain an understanding of the nature and extent of the audit procedures they perform and the related findings. This will assist us in determining whether, and how, the work of the internal audit function can be used.
