How Long Does an IOSH Certificate Last? Validity and Renewal Explained

28 April 2025

3 min read

How long is the IOSH Managing Safely certificate valid for?

Here is the fact that surprises most people: your IOSH Managing Safely certificate does not officially expire. IOSH itself confirms the certificate has no formal expiry date. Once you have passed, the qualification is yours.

In practice, though, the working answer is three years. IOSH recommends refreshing your knowledge with the one-day Managing Safely Refresher every three years so your training reflects current legislation and best practice, and many employers and principal contractors treat three years as the effective validity period when they audit training records. So while nobody can take your certificate away, expect to be asked for evidence of refresher training if yours is more than three years old.

How often should IOSH Managing Safely be refreshed?

Every three years is the standard recommendation, and it is what most UK employers apply in practice. The refresher is a single day, much shorter than the original three to four day course, so it is a straightforward way to keep the qualification working for you.

How long does it take to get your IOSH certificate?
