The NEBOSH Construction Certificate is the working name for Health and Safety Management for Construction (UK), NEBOSH’s current construction H&S qualification. It is a single-unit qualification (unit CN1) at SCQF Level 7 (RQF Level 4 in England, Wales and Northern Ireland), with about 70 taught hours plus around 40 hours of private study. Assessment is a single scenario-based open-book examination with a 48-hour completion window, sat online. The syllabus covers CDM 2015 dutyholder roles, construction-specific hazards (working at height, excavation, demolition, plant, electricity, fire and others), and the management framework that ties them together. Holders are eligible for the CSCS Academically Qualified Person (AQP) card and IIRSM Associate Membership (AIIRSM). Replaces the withdrawn NEBOSH National Certificate in Construction Health and Safety, last assessed in March 2023.
Construction accounts for more worker deaths than any other UK industry. The Construction (Design and Management) Regulations 2015 sit on top of an already busy compliance picture, including working at height, asbestos, manual handling, noise, occupational health, plant and electrical work. People charged with making sense of all that on site need a qualification that maps to the reality of construction risk. The NEBOSH Construction Certificate is that qualification. It is the standard credential UK contractors look for in site-based safety advisers, the foundation for principal contractor compliance work, and a common route into construction-sector roles for people with a general H&S background.
This guide explains what the qualification covers, who it is for, how it is assessed, and how it sits alongside the General Certificate, CSCS and SMSTS.
NEBOSH calls it Health and Safety Management for Construction (UK). Most providers and learners still use the shorter “NEBOSH Construction Certificate” name and that is the searchable label you will see throughout this guide. The official name is the one that appears on the certificate itself.
The qualification sits at SCQF Level 7 in the Scottish Credit and Qualifications Framework, with 12 SCQF credit points. That is comparable to RQF/CQFW Level 4 in England, Wales and Northern Ireland. SCQF Level 7 is higher than A Level but lower than degree level. It is one academic notch above the NEBOSH General Certificate (RQF Level 3 / SCQF Level 6).
The qualification is delivered as a single unit (CN1). There is no separate workplace risk-assessment unit, no second sitting and no NCC1/NCC2 split. (The earlier two-unit qualification, NEBOSH National Certificate in Construction Health and Safety, was withdrawn after March 2023.) Taught content is a minimum of 70 hours, with NEBOSH recommending another 40 or so hours of private study and revision.
The Construction Certificate is aimed at people who carry day-to-day responsibility for safety on construction projects. The audience splits broadly into four groups:
It is not aimed at the general construction workforce. CSCS cards and site-specific induction cover that. It is aimed at the people accountable for setting up and managing the work safely.
NEBOSH lists no formal entry requirements. English at IELTS 6.0 or equivalent is recommended because the open-book scenario assessment requires substantial written answers.
CN1 is a single unit organised into 13 elements covering construction-specific hazards and the management framework that controls them. Per NEBOSH’s official CN1 syllabus guide (specification January 2025):
NEBOSH describes the qualification as “guided by legislation but focussed on best practice”. The legal framework is taught (HSWA 1974, MHSWR 1999, CDM 2015, the Working at Height Regulations 2005, LOLER, COSHH and sector-relevant pieces), but the syllabus emphasises practical application of controls rather than legal recitation.
By the end of the course, NEBOSH expects learners to be able to:
CN1 is assessed by a single scenario-based open-book examination, delivered as a digital assessment. The format is:
There is no separate practical risk-assessment unit. The scenario-based format is designed so that answers reward applied judgement, not material recall. Learners cannot simply quote course content back.

A common comparison. Both are NEBOSH certificate-level qualifications, but they sit at different levels, cover different ground and are assessed differently.
| Aspect | NEBOSH General Certificate | NEBOSH Construction Certificate |
|---|---|---|
| Level (Scotland) | SCQF Level 6 | SCQF Level 7 |
| Level (England, Wales, NI) | RQF Level 3 | RQF Level 4 |
| Scope | All workplace hazards, cross-sector | Construction-specific, with CDM 2015 at the centre |
| Unit structure | Two units (GNC1 + GNC2) | Single unit (CN1) |
| Assessment | GNC1 24-hour open-book exam + GNC2 practical workplace risk assessment | Single CN1 scenario-based open-book exam, 48-hour window |
| Taught hours | ~66 taught hours | ~70 taught hours |
| Best for | Cross-sector H&S advisers, line managers, anyone moving into a workplace H&S role | Site-based construction roles, principal contractor reps, CDM dutyholders |
| Professional recognition | IOSH AIOSH (TechIOSH route) and IIRSM AIIRSM | IIRSM AIIRSM, plus CSCS AQP card eligibility |
Some learners take both. Holders of the General Certificate sometimes add the Construction Certificate when they move into construction; holders of the Construction Certificate occasionally add the General Certificate when their role broadens. Neither is a prerequisite for the other; both are standalone qualifications. The Construction Certificate cannot be made up of units from the General Certificate or any other NEBOSH qualification. NEBOSH states it is standalone.
For the broader picture on the General Certificate, see our guide to the NEBOSH General Certificate.
People new to construction H&S often confuse three things that sit alongside each other but serve different purposes. Most site-based safety roles need a combination of the three.
| Scheme | What it is | What it does |
|---|---|---|
| CSCS card | Industry card scheme covering construction occupations | Confirms a worker has the H&S awareness and occupational competence for site access. Holders of the NEBOSH Construction Certificate qualify for the Academically Qualified Person (AQP) card. |
| SMSTS (Site Management Safety Training Scheme) | 5-day site management course delivered by CITB-approved providers | Provides on-site supervisory safety knowledge. Industry-recognised but not an academic qualification. Complements rather than replaces a NEBOSH qualification. |
| NEBOSH Construction Certificate | SCQF Level 7 / RQF Level 4 academic qualification (CN1) | Provides the underpinning H&S knowledge and management framework. Counts towards CSCS AQP card eligibility and is widely the preferred credential for site-based safety roles. |
Many site managers hold all three: an SMSTS for the operational management knowledge, a CSCS card for site access, and the NEBOSH Construction Certificate for the academic H&S competence. None of them substitutes for the others.
For more on CSCS and how it fits with H&S qualifications, see our CSCS card and H&S qualifications guide.
The Construction (Design and Management) Regulations 2015 are the legal framework the Construction Certificate teaches around. CDM places explicit duties on six dutyholder roles: client, principal designer, principal contractor, designer, contractor, and worker. Each has competence requirements written into the regulations. The Construction Certificate provides the H&S knowledge those competence requirements assume.
For principal contractors specifically, CDM 2015 requires arrangements to be in place to plan, manage and monitor the construction phase, and to coordinate matters relating to health and safety. That competence is what the Construction Certificate is structured to teach. It does not, on its own, satisfy the regulations. The dutyholder still has to demonstrate the arrangements are real and proportionate to the project. The qualification is the foundation most principal contractors build on.
For the wider CDM context, see our CDM Regulations 2015 explained guide.
The Construction Certificate is the standard credential for several site-based roles. Holders typically move into one of:

NEBOSH specifies a minimum of 70 taught hours plus approximately 40 hours of private study and revision. Total elapsed time depends on the study mode:
After the taught content, learners sit the CN1 examination on one of NEBOSH’s scheduled sittings. NEBOSH typically lists three UK sittings per year (current dates on the NEBOSH page). Results arrive within 50 working days.
NEBOSH operates a tiered Learning Partner accreditation: Bronze, Silver and Gold. The tier reflects the depth of the partnership and the quality assurance NEBOSH applies. Gold Learning Partners have the longest-standing relationships with NEBOSH and are subject to the most active monitoring of teaching quality and learner outcomes.
KeyOstas has been a NEBOSH Gold Learning Partner since 2019. Gold tier matters in practical terms: tutor support is closer to the assessment standards NEBOSH applies, materials are kept current with syllabus changes (the move to single-unit CN1 in 2023 being the most relevant for construction), and pass rates at Gold partners run reliably above the sector average.
What to look for when choosing any Learning Partner:
No. They sit at different academic levels: the General Certificate is SCQF Level 6 / RQF Level 3; the Construction Certificate is SCQF Level 7 / RQF Level 4. They cover different ground: the General Certificate is cross-sector, the Construction Certificate is construction-specific and built around CDM 2015. They are assessed differently: the General Certificate has two units (GNC1 + GNC2); the Construction Certificate has one (CN1).
No. NEBOSH treats both as standalone qualifications. Either can be taken first. Learners working firmly in construction often take the Construction Certificate as their only certificate-level qualification.
A minimum of 70 taught hours plus around 40 hours of private study. Total elapsed time from start to certification is typically 3 to 6 months depending on study mode.
SMSTS is a 5-day site management course providing operational on-site supervisory knowledge. The NEBOSH Construction Certificate is an academic qualification (SCQF Level 7 / RQF Level 4) providing the underlying H&S management framework. Many site managers hold both.
Yes. NEBOSH-accredited online and distance-learning options are widely available. CN1 is sat remotely with a 48-hour window. Virtual classroom delivery is now standard at many Learning Partners.
CN1 is a digital scenario-based open-book examination with a 48-hour window. Learners download the paper, complete it within that window, and submit online. The exam tests applied judgement on a realistic construction scenario rather than recall of syllabus material.
The qualification provides the H&S knowledge that competence requires. A qualification on its own does not satisfy CDM. The principal contractor still needs to demonstrate the arrangements to plan, manage and monitor the construction phase are real and proportionate to the project.
Holders qualify for:
The qualification does not count toward IOSH membership at any tier. If you need the IOSH pathway, the General Certificate is the certificate-level NEBOSH qualification that grants AIOSH eligibility (with TechIOSH after relevant experience).
Partially. SCQF Level 7 (Scotland), with 12 SCQF credit points. That maps to RQF Level 4 in England, Wales and Northern Ireland. NEBOSH’s own materials sometimes use “Level 7” without specifying the framework; the safest description is “SCQF Level 7, comparable to RQF Level 4”. It is not RQF Level 7 (which would be Master’s degree level).
If the NEBOSH Construction Certificate is the right qualification for your role, the next step is choosing a delivery mode and Learning Partner that suits your work pattern. KeyOstas delivers the qualification in classroom, virtual classroom and on-site formats as a NEBOSH Gold Learning Partner.
