ISO Internal Audit Services

What is an ISO Internal Audit?

ISO internal audits are a structured review of your management system, processes and controls to assess whether they meet the requirements of the relevant ISO standard and your own internal procedures.

Internal audits are required by standards such as ISO 9001, ISO 27001 and ISO 22301, and help organisations evaluate how effectively their management systems are operating. They also identify areas for improvement before external certification audits take place.

An effective internal audit provides an objective assessment of how well processes are being followed in practice, highlights potential risks and non-conformities, and identifies opportunities to improve performance.

Regularly auditing your management system enables you to maintain certification readiness and strengthen governance. Many organisations choose to use an independent external consultant to conduct internal audits, ensuring objectivity and access to specialist expertise.

“It’s been a delight to deal with Evalian – they are exemplars of good, professional service. My initial web inquiry instigated a same-day meeting with our account manager, who instantly discovered what we needed (support for an internal ISO27001 audit). A proposal followed sooner than promised, which we were pleased to accept. Then we met with our consultant – the most knowledgeable, engaging and helpful auditor you could wish to know. Jack led us through 3 days of intense audit with empathy, spirit and professionalism. He has coached us to become a better business. I look forward to working with them again.” – Nick Delacamp, A24

Why Use an Independent Internal Auditor?

Many organisations choose an independent ISO auditor like Evalian to bring an objective perspective to their management system. Internal teams can often be too close to day-to-day operations, making it difficult to identify gaps, inefficiencies, or areas where processes have drifted from documented procedures.

Independent audits reduce bias and provide access to experienced ISO specialists who understand the practical challenges organisations face. They can offer valuable insight into compliance, risk, and continual improvement opportunities, while helping to ease pressure on internal resources. An external audit also provides reassurance that your management system is being assessed thoroughly and consistently.

 Trustindex verifies that the original source of the review is Google. This particular review is for Neil and Joe, who have been incredibly supportive and patient. Evalian were recommended to us by our lawyer as we were looking for support regarding GDPR policies and processes. Nothing seems too taxing for Neil, despite probably asking him numerous silly questions. I am unsure how he does it, but Neil seems to make dealing with GDPR processes less onerous and more fun. With a brilliant sense of humous and fantastic communication skills, which we as a company value very highly, Evalian comes very highly recommended. Kudos also to Joe, who helped us find the right person at Evalian to work with. Thanks Evalian!

We have been running a project to update all of our GDPR policies and processes to ensure we remain compliant. Neil our contact at Evalian was on hand 24/7 providing speedy and accurate responses. Often turning around work within the same day if not the same week. The teams dedication to understand the scope of the project, provide their recommendations and expertise was outstanding. I look forward to continuing to work with Evalian and their team. It has made GDPR a whole lot easier to handle and we have now rolled this out in house with simplicity and ease thanks to Neil and his team. Thankyou and I hope we will continue to work together for many more years!

 Trustindex verifies that the original source of the review is Google. I worked with Evalian on a gap analysis project for my organisation. The process was seamless, well communicated and collaborative. Working with John and Neil was a pleasure, they spent time with me to explain the process in detail, understand my needs and organisation and alleviate any concerns along the way. I now have a comprehensive report with clear actions I can drive forward. Would 100% recommend!

 Trustindex verifies that the original source of the review is Google. Evalian recently supported us with implementation of ISO 27001 and ISO 27701. Our consultants - Jamie, Daniel and Ray - shared a vast amount of experience and knowledge, and gave us a lot of suggestions, understanding very well the peculiarities of our organization and processes.
Weekly calls were very useful to keep the project on track.
The 2 auditors assigned for the ISO 27001 assessment were very happy with the quality of our documentation, partially due to Evalian.
We will highly recommend company and team; we're immensely grateful for their support.

FAQs

What is an ISO internal audit?

An ISO internal audit is a systematic review of your management system, processes, and controls to determine whether they meet the requirements of the relevant ISO standard and your own documented procedures. Internal audits help identify non-conformities, assess effectiveness, and support continual improvement.

Are ISO internal audits mandatory?

Most ISO standards, including ISO 9001, ISO 27001, ISO 14001, and ISO 22301, require organisations to conduct internal audits at planned intervals. Internal audits are a key part of maintaining certification and demonstrating ongoing compliance.

How often should an ISO internal audit be conducted?

The frequency of internal audits depends on your organisation, risks, and certification requirements. Many organisations operate an annual audit programme, although higher-risk areas may be audited more frequently. Audit schedules should be based on the importance and performance of the processes being reviewed.

Can internal audits be outsourced?

Yes. Many organisations choose to outsource internal audits to an independent ISO specialist like Evalian. External auditors provide an objective assessment, reduce internal resource pressures, and bring experience gained from auditing a wide range of organisations and management systems.

What happens if non-conformities are identified?

Identifying non-conformities is a normal and valuable outcome of the audit process. Findings are documented in a clear audit report, along with recommendations for corrective action. Where required, we can also provide guidance on addressing findings and improving management system performance.

Will an internal audit help us prepare for certification?

Yes. Internal audits are one of the most effective ways to prepare for certification, surveillance, and recertification audits. They help identify gaps before external auditors do, giving your organisation time to address issues and strengthen compliance.

Are internal audits carried out remotely or on-site?

Both options are available. Depending on your organisation, management system, and audit scope, internal audits can be conducted remotely, on-site, or through a combination of both approaches.
