Providing a Comprehensive and Independent QMS Assessment

ISO 9001 internal audits are a key requirement for maintaining a compliant and effective Quality Management System (QMS). They help organisations verify that processes are being followed, identify non-conformities, and drive continual improvement.

Regular internal audits provide valuable insight into how well your QMS is functioning and whether it continues to meet ISO 9001:2015 requirements.

Patient Guard acts as your independent internal audit partner, delivering objective, expert-led audits that assess your Quality Management System against ISO 9001 requirements and your own internal procedures.

Without effective internal audits, organisations may overlook compliance issues, process weaknesses, and opportunities for improvement before external certification or surveillance audits.

Patient Guard provides expert ISO 9001 internal audit services for organisations across all sectors. We support audit planning, execution, reporting, and corrective action follow-up.

Whether you are preparing for initial certification, maintaining certification, or improving your QMS, we ensure your system is fully audit-ready.

Alex Lewis - Patient Guard - Quality Assurance Manager
"The best way to pass an external assessment is to have already survived a more rigorous internal one. We provide the critical, objective eye needed to verify your QMS is functioning exactly as intended, giving you total confidence before your certification body arrives."

Frequently Asked Questions (FAQs)

An ISO 9001 internal audit is a structured review of your Quality Management System to verify compliance with ISO 9001:2015 and ensure the system is effectively implemented.

Internal audits should be conducted at planned intervals, usually annually or based on process importance, risk, and previous audit results.

Yes, Patient Guard provides independent internal auditors to ensure objective and unbiased audit results.

Any non-conformities found during the audit should be addressed through corrective action. We can also support CAPA planning and follow-up.

Audit duration depends on the size and complexity of the organisation, but most internal audits take between 1–3 days.

ISO 9001:2015 Clause 9.2.2 requires that auditors be objective and impartial. It is often difficult for small medical device teams to audit their own processes without bias.

Working with the Patient Guard team has been a great experience throughout our MHRA and ISO 13485 documentation journey. Their expertise, structured approach, and practical guidance helped our team build a robust quality management system while keeping us aligned with regulatory expectations. The collaboration was professional, responsive, and focused on finding solutions rather than simply identifying issues. A special thank you to Alex and Steve for their outstanding coordination, responsiveness, and continuous support throughout the project. They were always approachable, provided valuable feedback, and worked closely with our team to resolve challenges efficiently. Their commitment made a significant difference in keeping our documentation effort on track. I highly recommend Patient Guard to any healthcare or MedTech organization looking for experienced regulatory and quality system partners for MHRA, ISO 13485, and broader medical device compliance initiatives. Thank you again to the entire Patient Guard team for being such reliable partners.

STEPPER design, manufacture & distribute eyewear across the globe. With the increasingly complex landscape concerning the placing of Mecial Devices onto the market, we realised we needed professional guidance. We found Patient Guard via a simple internet search and are delighted we did! They provide a pragmatic solution to our needs, are totally reliable & always available to answer our (often simplistic) questions. They are highly efficient & responsive to what is a changing picture in our world and nothing is too much trouble. We have a much better understanding of regulatory affairs and our responsibilities as manufacturers & distributors and they support us in navigating the requirements in different territories. Updating our Declaration of Conformity, ensuring our labelling is compliant and acting as our PRRC are the key areas of their service for us.
