External Audit Services Delivered by Registered Statutory Auditors
Shareholders, lenders, and regulators need to know your financial statements can be trusted. ABM Chartered Accountants delivers external audits that provide an independent opinion on whether your accounts give a true and fair view, carried out to FRC auditing standards.
Statutory Audits From Chartered Accountants You Trust
An external audit is an independent examination of your company’s financial statements by a registered statutory auditor. It results in an audit opinion on whether those statements give a true and fair view. Companies that exceed the statutory audit thresholds, or that are required to be audited by their articles or stakeholders, must have one.
Our ICAEW and ACCA qualified accountants conduct external audits under International Standards on Auditing (UK) issued by the FRC. We take a risk-based approach, test your key controls, verify material balances, and deliver a clear audit opinion along with a management letter highlighting areas for improvement.
What Our External Audit Service Covers
From statutory audit to management letter reporting, here is how ABM Chartered Accountants delivers external audits that give your stakeholders the independent assurance they require.
Statutory Audit
Auditing your company's financial statements to confirm they give a true and fair view as required.
Group Audit
Auditing consolidated group accounts where a parent company has one or more subsidiary entities.
Subsidiary Audit
Auditing individual subsidiary company accounts to meet group or regulatory audit requirements.
Voluntary Audit

Audit Planning & Execution
Designing and delivering a risk-based audit approach tailored to your business and its controls.
Management Letter
Reporting our audit findings with practical recommendations to strengthen your financial controls.
Independent Assurance That Your Stakeholders Rely On
An external audit is more than a legal requirement. It gives shareholders confidence in the numbers they receive, gives banks and lenders comfort when extending credit, and gives directors assurance that the financial statements they sign are accurate. ABM Chartered Accountants delivers that assurance with a thorough, risk-based approach that adds real value.
The management letter that accompanies every audit also identifies weaknesses in your internal controls, accounting processes, and financial reporting. These recommendations help you strengthen your systems, reduce the risk of error or fraud, and improve the quality of your financial information for decision making.

Frequently Asked Questions
Here are answers to the external audit questions we hear most often. Contact our team for tailored guidance.
Does my company need an external audit?
Your company needs a statutory audit if it exceeds two of the three size thresholds: turnover above 15 million pounds, balance sheet total above 7.5 million pounds, or more than 250 employees. Companies in regulated sectors or those required by their articles may also need one.
What changed with the audit thresholds in 2025?
From April 2025, the size thresholds for small company classification increased significantly. Turnover rose from 10.2 million to 15 million pounds and the balance sheet total rose from 5.1 million to 7.5 million pounds. This means many previously audited companies now qualify for exemption.
Can I still have an audit if I am exempt?
Yes. Many companies choose to have a voluntary audit even when they fall below the statutory threshold. This may be because their bank requires it, their articles of association mandate it, or their shareholders holding at least 10 percent of shares request one.
What does an external audit involve?
An external audit involves planning the audit approach, assessing risk, testing internal controls, verifying material account balances and transactions, reviewing disclosures, and forming an opinion on whether the financial statements give a true and fair view. ABM Chartered Accountants follows ISAs (UK) throughout.
What is a management letter?
A management letter is a report issued alongside the audit opinion that sets out any weaknesses or recommendations identified during the audit. It highlights areas where your internal controls, processes, or financial reporting could be improved. It is a valuable part of every external audit.
How much does an external audit cost?
Fees depend on the size of your company, the complexity of your operations, and the quality of your accounting records. We offer transparent, fixed-fee pricing agreed before the audit starts. Contact ABM Chartered Accountants for a tailored quote for your business.
