A.C.T. Audit is the perfect solution for international companies operating in the UK seeking to meet statutory and voluntary audit requirements. We add value by providing effective internal control recommendations through the Communications with those Charged with Governance (ISA 260).


We have strong working relationships with many of the top international audit firms, working as a component auditor on group audit assignments. We provide group auditors with full access to our working paper files and go well beyond the standard requirements of ISA600 to ensure principal auditors have regular direct updates at each stage of the assignment.

Global networks who work with A.C.T. Audit benefit from working with an independent UK audit firm, and the services provided by our specialised audit team trained within the audit departments of big four firms.
We have extensive experience of auditing consolidated financial statements, and acting as principal auditor co-ordinating the working of local auditors.

A.C.T. Audit is regulated by the Association of Chartered Certified Accountants and by the International Standard on Quality Control (UK) issued by the Financial Reporting Council. We have implemented a system of quality control procedures in respect of all audit work carried out by the firm. Our audit files are subject to independent quality control procedures, including voluntary hot reviews by independent quality control reviewers who comply with the ethical standards issued by the Financial Reporting Council. Our reviewers have the necessary qualifications, competence and experience to carry out file reviews in accordance with International Standard on Quality Control (UK).
