Frequently Asked Questions

An ICAEW registered audit firm is an accountancy practice that has been registered with the Institute of Chartered Accountants in England and Wales (ICAEW) to conduct statutory audits. This registration ensures the firm meets strict professional standards, regulatory requirements, and has the necessary expertise to perform audits in compliance with UK legislation. Acumon is an ICAEW registered audit firm authorised to conduct audits across the UK, Jersey, and the Isle of Man.

Acumon provides comprehensive audit services including statutory audits for limited companies, Public Interest Entity (PIE) audits authorised by the Financial Reporting Council, charity audits compliant with Charity SORP, group audits for international groups, and audits for organisations with UK turnover ranging from £1m to £500m. We also conduct audits for PLCs, partnerships, LLPs, and UK subsidiaries of international groups.

The duration of an audit depends on the size and complexity of your organisation. A typical audit for a small to medium-sized company may take 4-8 weeks from planning to completion, while larger or more complex audits may take 8-12 weeks or longer. We work closely with you throughout the process to minimise disruption and ensure timely completion. Our digital portal and Inflo analytics platform help streamline the audit process and improve efficiency.

A Public Interest Entity (PIE) audit is required for certain organisations that are considered to be of public interest, such as listed companies, banks, insurance companies, and other entities specified by the Financial Reporting Council. Acumon is FRC-authorised to conduct PIE audits. If your organisation meets PIE criteria, you must use an FRC-authorised audit firm. We can help determine if your organisation requires a PIE audit and provide the necessary services.

To prepare for an audit, you should gather all relevant financial records including accounting records, bank statements, invoices, contracts, payroll records, and any supporting documentation. Ensure your accounting system is up to date and all transactions are properly recorded. Our team will provide a detailed list of required documents and work with you to ensure everything is ready. We also offer guidance on how to prepare your financial statements and supporting schedules.

Audit costs vary depending on the size and complexity of your organisation, the scope of work required, and the time involved. We provide transparent, fixed-fee quotes based on your specific circumstances. Factors that influence cost include company size, number of transactions, complexity of operations, and any special requirements. Contact us for a tailored quote based on your organisation's needs.
