The NEBOSH National General Certificate is a Level 3 qualification in occupational health and safety, equivalent to an A Level. It takes around 80–120 hours of study (typically 10 days of teaching plus self-study) and is assessed through an open-book exam (GNC1, previously NG1) and a workplace-based risk assessment (GNC2, previously NG2). It is the standard entry qualification for safety officer, advisor and coordinator roles. Around 230,000 people worldwide hold this certificate.
The NEBOSH National General Certificate is the most widely recognised health and safety qualification in the UK. If you’re planning a career in health and safety, or your employer has asked you to take responsibility for it, this is almost certainly the qualification you’ll be asked to hold.
This guide covers what the certificate actually involves — course content, study time, assessment, cost, and the kind of jobs it qualifies you for. If after reading you’re ready to enrol, you can book directly on our NEBOSH National General Certificate course page.
The NEBOSH National General Certificate in Occupational Health and Safety is a Level 3 vocational qualification awarded by NEBOSH (the National Examination Board in Occupational Safety and Health). It’s recognised in over 130 countries and is the foundational qualification for working in health and safety in the UK.
Key facts:
The qualification suits four types of learner:
If you want to work as a Health and Safety Officer, Advisor, Coordinator or similar, the NEBOSH General Certificate is almost always the minimum entry requirement. It’s a sensible first step because it covers the breadth of health and safety practice without requiring prior knowledge.
If your role has expanded to include responsibility for the health and safety of a team, the NEBOSH General Certificate gives you the depth that shorter awareness courses don’t. It’s the right choice when you need to design risk assessments, lead investigations or represent the business on safety matters — not just discharge daily duties.
Construction, oil and gas, manufacturing, food and drink, logistics — these sectors operate under strict regulatory regimes where holding the General Certificate is often a contractual requirement for site managers, contractors and supervisors.
The certificate has no formal entry requirements, which makes it accessible to people moving into health and safety from operations, HR, facilities, engineering or any other discipline. We see this regularly — operations managers who’ve informally been doing safety work for years, finally formalising it.
The qualification is split into two units. You can sit them independently — many learners take GNC1 first, then GNC2 — but you need to pass both within five years to be awarded the full certificate.
The theoretical unit. GNC1 covers the principles and practice of safety management:
GNC1 is assessed through an open-book exam (see below).
The practical unit. GNC2 requires you to carry out a workplace risk assessment in your own workplace, document your findings, and submit a written report. It is not exam-based; it is a workplace project completed in your own time, showing that you can apply GNC1 theory in real conditions. You submit it through the NEBOSH platform 10 working days after your GNC1 exam.
GNC2 is marked on a points-based system with a 60% pass mark. This is a change from the older approach: rather than one overall judgement on whether the work reached the standard, your report is now scored against set criteria, and NEBOSH issues a mark breakdown document showing where points were gained and lost. Your GNC1 and GNC2 results are released together on the same day, 60 working days after the GNC1 exam.
For learners who don’t have access to a workplace, KeyOstas can arrange access to a partner site for the practical assessment.
By the end of the qualification you’ll have the technical depth and practical confidence to lead workplace H&S in any UK organisation, from a small office to a multi-site operation across construction, manufacturing, healthcare or the public sector.
Apply HSG65 plan-do-check-act, develop policy, organise responsibilities and verify competence across your organisation.
Apply the 5-step process, hierarchy of control and ALARP to identify hazards and select proportionate controls.
Lead structured investigations, complete RIDDOR reporting and feed lessons learned into safer ways of working.
Develop H&S policy, drive worker engagement and embed positive H&S culture from the boardroom to the shop floor.
Control physical, psychological, chemical, biological, mechanical, electrical and fire hazards across the workplace.
Apply the Health and Safety at Work etc Act 1974, MHSWR 1999, COSHH, PUWER, the Manual Handling Operations Regulations and RIDDOR to live workplace decisions.
GNC1 is a 24-hour open-book exam delivered remotely. You receive the question paper electronically, complete it in your own time within the 24-hour window, and submit electronically. You can use any reference materials — your course notes, the NEBOSH textbook, online sources — but the answers must be your own work. NEBOSH uses plagiarism detection on every submission.
The exam typically presents a workplace scenario followed by questions asking you to apply health and safety principles to that scenario. NEBOSH publishes specimen papers on its website if you want to see the format.
After the open-book exam, you’ll be invited to a short closing interview — a video call where a NEBOSH-appointed examiner asks you to explain your answers. This is to confirm the work is your own. It’s not a re-test; if you wrote the answers, you’ll have no trouble.
You select a workplace, identify hazards, evaluate risks, recommend controls, and produce a written report. The report is assessed against published criteria. Most learners take three to four weeks to complete GNC2 alongside other commitments.
It depends on the format. Three typical timelines:
| Format | Teaching schedule | Total elapsed time |
|---|---|---|
| Block release | 10 consecutive days | 6–10 weeks (including exam and GNC2) |
| Day release | One day per week for 10 weeks | 4–6 months |
| Distance learning | Self-paced | 3–12 months |
Total study time is around 80–120 hours regardless of format. Block release is faster but more intense. Distance learning is slower but fits around full-time work.
UK pricing varies considerably across providers — from low-cost self-study video courses with no tutor support, through to premium tutor-led classroom delivery from Gold-tier NEBOSH Learning Partners. The headline price often doesn’t tell you what’s actually included.
When comparing providers, the questions worth asking are:
KeyOstas pricing reflects what we deliver: tutor-led teaching from NEBOSH and IOSH-experienced practitioners, NEBOSH Gold Learning Partner status (the highest NEBOSH tier), full inclusion of registration and both unit exam fees, GNC2 risk assessment guidance, and pre- and post-exam tutor support. For current pricing, course dates and full details of what’s included, see the NEBOSH National General Certificate course page.
NEBOSH publishes overall pass rates around 60–70% for the General Certificate. That’s the global average across all Learning Partners and delivery formats.
Pass rates at individual Learning Partners vary considerably. Quality of teaching, access to a tutor, exam preparation, and the rigour of GNC2 feedback all influence outcomes. KeyOstas consistently exceeds the national average — our first-time pass rate runs at 85% or above.
For more on what drives pass rates and how to maximise your own chances, see our guide to how we deliver the General Certificate.
The General Certificate qualifies you for entry-level and mid-level health and safety roles. Common job titles include:
UK salaries for these roles currently run from around £28,000 (entry-level officer) to £45,000 (experienced advisor or coordinator). London and the South East tend to pay 10–15% above national averages.
If your career goal is more senior — Head of Safety, HSEQ Manager, Director-level — you’ll typically need to progress to the NEBOSH National Diploma after the General Certificate. The Diploma is the standard for mid-to-senior safety leadership roles.
Typical UK earning ranges for NEBOSH General Certificate holders:
| Role | UK salary range |
|---|---|
| H&S Adviser | £32k–£48k |
| H&S Officer | £28k–£42k |
| EHS Coordinator | £32k–£45k |
| SHEQ Manager | £50k–£75k |
| H&S Manager | £55k–£85k+ |
Approximate UK ranges as of 2026; verify against a current job board for live figures. Higher in regulated industries (oil & gas, pharma, nuclear), Tier-1 manufacturing, healthcare leadership and London-area roles. Day rates for contract H&S roles average £350–£500.
Yes. Holders of the NEBOSH General Certificate are eligible to apply for Technical Membership (Tech IOSH), which is the level of IOSH membership that recognises practising safety competence below Chartered status. It’s a useful credential to add to your CV alongside the certificate itself.
The NEBOSH General Certificate is a Level 3 RQF qualification giving broad technical coverage of H&S management, risk assessment and workplace hazards. It’s designed for people moving into a workplace H&S role. IOSH Managing Safely is a short awareness course for line managers who need day-one H&S competence rather than an academic credential. See our NEBOSH vs IOSH guide for the full comparison.
The NEBOSH National General Certificate covers UK law and regulatory practice. The International General Certificate (IGC) covers ILO conventions and international good practice rather than any one country’s legislation. If you’re working in the UK, take the National. If you’re working internationally, take the IGC. The structure, depth and study time are equivalent.
NEBOSH approves Learning Partners on a tiered system: Bronze, Silver and Gold. Gold Learning Partners — the highest tier — are required to demonstrate sustained quality, robust internal verification and consistently high pass rates. There are around 100 Gold Learning Partners worldwide.
KeyOstas has been a NEBOSH Gold Learning Partner since 2019. We’ve been delivering NEBOSH qualifications since 1984 — 41 years of continuous NEBOSH delivery, longer than most competitors have been in business.
When choosing a provider, the questions worth asking:
For more on this, see our NEBOSH vs IOSH guide if you’re still deciding which route is right for you.
It’s harder than awareness-level qualifications like IOSH Managing Safely, but it’s not academically demanding in the way a degree is. Most learners pass first time with proper preparation — around 80–120 hours of study including teaching time. The most common reason for failing GNC1 is treating the open-book exam as easier than it is. The questions reward applied knowledge, not the ability to look things up.
No formal entry requirements. NEBOSH recommends English at IELTS 6.0 level or equivalent, because both GNC1 and GNC2 require substantial written answers. There’s no minimum age, no prior qualification required, no specific work experience needed.
Yes. Online options range from self-paced video courses (cheap, but you’re on your own) to live virtual classroom delivery with a tutor (more expensive, much higher pass rates). KeyOstas offers virtual classroom delivery alongside in-person and on-site options.
You can resit failed units. There’s a resit fee charged by NEBOSH (separate from your original course fee), and you’ll need to wait until the next available exam window. KeyOstas provides post-exam support and revision help to learners who need to resit. Most resit candidates pass on their second attempt.
No. Once you’ve passed both GNC1 and GNC2, the qualification is yours permanently. There’s no renewal requirement, though continuing professional development (CPD) is expected if you become a Tech IOSH member.
The National General Certificate covers UK law and regulatory practice. The International General Certificate (IGC) covers ILO conventions and international good practice rather than any single country’s legislation. If you’re working in the UK, take the National. If you’re working internationally, take the IGC. The structure, depth and study time are equivalent.
