Choosing an internal auditor course in the UK can feel harder than the audit itself. Do you go ISO 9001, 27001 or 17025? Is CQI and IRCA accreditation essential, or will a provider certificate do? Can your team learn online without losing the practical edge you need on site? With budgets tight and standards evolving (hello, ISO 27001:2022), you need training that’s recognised, hands-on and aligned to your sector—without wasting days out of the business.
This guide does the legwork for you. We’ve shortlisted eight of the best internal audit training courses in the UK for 2025, covering ISO management systems (9001, 14001, 45001, 27001), laboratory competence (ISO/IEC 17025), food safety (BRCGS) and professional internal auditing practice. For each provider, you’ll see what the course covers, who it’s best for, how it’s delivered and assessed, the accreditation behind the certificate, and a price guide so you can compare like for like. Whether you need a two‑day ISO internal auditor, a certified 27001 route, or a one‑day skills refresher, use this list to pick a credible option and get auditing with confidence.

- Recognition required: Employer, client or regulator expectations.
- Sector fit: ISMS, labs, food, QMS/EMS/OHS, or mixed.
- Delivery fit: Classroom, virtual, e‑learning or in‑house.

- Progression path: Step to Lead Auditor or advanced skills.
