Preparing for a UK statutory audit: practical considerations for finance teams
02 March 2026
As the busy US audit season draws to a close, your attention may now be shifting to the reporting and audit requirements for your subsidiary undertakings in other jurisdictions.
Our article below outlines how you can begin preparing for your UK audit and offers practical guidance to help ensure you are fully ready.
A statutory audit can feel demanding, but it remains a critical process for maintaining financial integrity and meeting regulatory obligations in the UK.
Whether you are a small business owner or part of a larger organisation, preparing effectively can streamline the process and reduce disruption, particularly as compliance expectations and documentation standards continue to evolve.
How to prepare for a UK audit
Entering the audit process without adequate preparation often results in delays, inefficiencies and increased costs, placing pressure on both internal teams and auditors. Early planning, including reviewing prior year recommendations, plays an important role in delivering a smooth and well-managed audit.
You know your business better than anyone else. It is therefore good practice to document:
- Changes in operations, systems or key personnel
- Significant transactions during the year
- Upcoming events that may affect financial reporting
- Forecasts and budgets prepared for going concern assessments
- Any identified gaps in internal controls for auditors to be aware of
- Controls or systems currently in place
- Supporting evidence for all closing balance sheet balances, with any differences reconciled or corrected
Common challenges
Accounting issues
Overlooking changes in accounting standards or updated recognition criteria for transactions and balances can create avoidable complications during fieldwork.
Collation of data
Obtaining appropriate supporting data from multiple sources can be time-consuming. Identifying the right individuals to provide information may also prove difficult, particularly where several systems feed into the accounting system or where operations span multiple jurisdictions.
A disciplined month-end close process and a comprehensive financial reporting package often provide much of the information required for a UK financial statement audit.
Time constraints
Managing auditor requests alongside internal deadlines can affect readiness. Setting aside a defined preparation window and maintaining regular check-ins with the audit team can support a steady flow of information and minimise bottlenecks.
Consideration of projections
Detailed forecasts are required when auditors assess going concern. Careful attention should be given to supporting key assumptions, modelling sensitivities and clearly documenting management’s conclusions.
Internal control documentation
Auditors review internal controls to identify potential areas of risk. Clear documentation of control processes, combined with an internal assessment of potential weaknesses, can save time and maximise the value of your audit.
Accounting policy misalignments
Certain transactions, including long-term contract accounting, require specific treatment and should be reviewed before the audit commences, with assumptions appropriately supported.
International groups applying local GAAP (such as US GAAP) to overseas subsidiaries (using UK GAAP) may encounter differences in accounting treatment. Addressing these matters during audit planning helps avoid late adjustments to your trial balance.
Integrity of the trial balance
Auditors are required by ISA 500 to consider the consistency and reliability of information. Using an appropriate accounting system and reconciling balances with supporting evidence on a regular basis can reduce the risks of fraud or error and improve the audit process.
Intercompany positions
For group entities, balances with related parties should be reconciled in advance. Auditors typically seek balance confirmations to obtain sufficient appropriate evidence. Unreconciled positions can delay procedures and complicate consolidation adjustments.
Communication
With many audits now conducted remotely and finance teams dispersed across locations, clear communication is more important than ever. Scheduled planning meetings between management and auditors contribute to a more coordinated process.
Embedding an audit mindset internally
A statutory audit should not be viewed solely as an annual compliance requirement. Many of its disciplines can be incorporated into internal processes to strengthen financial oversight throughout the year.
For example:
- Reviewing and implementing any audit findings communicated by the auditors and discuss internally with your team
- Reviewing the trial balance periodically can help identify areas of concern that can be addressed ahead of the audit
- Updating control manuals for changes in systems, controls, approval processes, and personnel can refine internal procedures and mitigate risk
- Maintaining dialogue with your audit team throughout the year helps foster a long-term relationship and ensures any questions are answered as they arise
- Keeping auditors informed of significant events during the year so expectations remain aligned
Embedding these practices supports stronger internal controls, reduces risk and contributes to more efficient audits over time.
