What's the difference between IOSH Working Safely and IOSH Managing Safely?
IOSH Working Safely is a 1-day awareness course for every employee, covering hazard spotting and personal responsibility. IOSH Managing Safely is a 3-day course for line managers and supervisors, covering practical hazard assessment, risk control and incident investigation. Both are awarded by the Institution of Occupational Safety and Health and widely accepted across UK construction.
Key facts
- IOSH Working Safely – 1 day. Audience: all employees. Awareness level.
- IOSH Managing Safely – 3 days. Audience: line managers, supervisors and team leaders. Practical management level.
- Both are awarded by the Institution of Occupational Safety and Health, the UK’s chartered body for occupational safety professionals.
- Both certificates are valid indefinitely. IOSH recommends a refresher every 3 years to keep knowledge current.
- Working Safely sits at the level CSCS green-card holders are typically asked to demonstrate; Managing Safely sits at the level main contractors expect of site supervisors.
- Neither course is a legal requirement on its own, but both satisfy the “adequate training” duty under the Health and Safety at Work Act 1974.
Who runs IOSH and why it matters
The Institution of Occupational Safety and Health is the chartered professional body for health and safety in the UK. Founded in 1945, IOSH sets the syllabus, assessment standards and trainer accreditation for the courses that carry its name. IOSH certificates are recognised by main contractors and pre-qualification frameworks across UK construction and the wider industry. When a contractor asks for “an IOSH ticket” in a tender or PQQ, they almost always mean one of these two: Working Safely for operatives or Managing Safely for supervisors.
IOSH Working Safely: who it is for
Working Safely is the entry-level IOSH course. It is designed for any employee in any sector, with no prior safety training assumed. The syllabus covers the basics every worker should know: defining hazard and risk, identifying common hazards on site (slips and trips, manual handling, working at height, electricity, machinery), how to protect the environment around the workplace, and what to do if something goes wrong. Assessment is a short multiple-choice test and a hazard-spotting exercise. The course is typically delivered in 1 day, classroom or remote-instructor format. It suits operatives, apprentices, office staff who occasionally visit site, sub-contractors on short-term placements and graduate trainees in their induction period.
IOSH Managing Safely: who it is for
Managing Safely is the IOSH course aimed at people who plan and direct work, not just carry it out. The audience is line managers, supervisors, foremen, project managers, team leaders, gangers and contracts managers. The syllabus goes deeper than Working Safely: assessing risks under the Management of Health and Safety at Work Regulations 1999, controlling hazards using the hierarchy of control, understanding personal responsibility under the Health and Safety at Work Act 1974, investigating incidents and writing the report afterwards, and measuring performance via leading and lagging indicators. Assessment is a written exam plus a workplace risk assessment project completed back at site. Delivered in 3 days, typically over 3 consecutive days or in 1-day blocks across a fortnight.

Refreshers and the “valid forever” misconception
An IOSH certificate does not formally expire. That is not the same as “valid forever in the contractor’s eyes”. Main contractors and PQQ frameworks routinely ask for IOSH certificates dated within the last 3 years on submitted CVs and ticket lists. IOSH itself recommends a refresher every 3 years to keep the certificate respected at PQQ stage. A 1-day IOSH Managing Safely Refresher exists for that purpose. If your team’s certificates are older than 3 years and you are about to bid for work, the refresher is the cheapest way to remove the question from the tender response. See our Managing Safely Refresher course page for current dates.
Where IOSH sits next to NEBOSH
IOSH and NEBOSH are the two best-known safety qualifications in UK construction. They serve different purposes. IOSH Working Safely and Managing Safely are short courses that build practical safety knowledge for workers and supervisors. NEBOSH qualifications are longer, more academic and lead to a recognised certificate that a dedicated health and safety officer or advisor would hold on their CV. A typical career path: IOSH Working Safely as an operative, IOSH Managing Safely on promotion to supervisor, then NEBOSH National General Certificate if you move into a dedicated H&S role. For the full comparison see our IOSH vs NEBOSH FAQ.

We also run the Managing Safely Refresher for teams whose certificates need bringing back inside the 3-year window. Group bookings of 6 or more typically work out cheaper per head than individual centre bookings; on-site delivery removes downtime entirely.

Quick answers to related questions
Does an IOSH certificate expire?
IOSH certificates have no formal expiry date. IOSH recommends a refresher every 3 years to keep knowledge current, and most main contractors expect IOSH certificates on submitted CVs to be dated within the last 3 years.
Is IOSH Managing Safely a legal requirement for supervisors?
No. There is no UK law that names IOSH Managing Safely specifically. The Health and Safety at Work Act 1974 requires employers to provide adequate safety training to supervisors. Managing Safely is the most widely accepted way of meeting that duty in construction.
Can I do IOSH Managing Safely if I’ve never done Working Safely?
Yes. Managing Safely is a stand-alone course with no formal prerequisite. Working Safely is recommended where the candidate has no prior safety training, but for most line managers in construction Managing Safely is the right entry point.
